Canon EOS camera errors

The camera in the last three decades has evolved a lot. Going from being a mechanical device to a highly sophisticated one, with a control panel and interior components very similar to a computer.

Like computers, they can sometimes get into internal "conflict" and crash. With a restart, many times the problem is solved, as it happens with computers and we can return to work normally.

In current Canon cameras, a series of codes have been installed that provides a lot of information about the type of error that is affecting the camera. Giving the user at least an idea of ​​what is happening.

On other occasions we have already talked about the most common errors in Canon EOS cameras, today we want to continue listing the most common error codes. And in turn, the possible steps that the user can follow to try to solve the problem on their own.

Error 10 - File Malfunction

This error is indicating an error in the files on the memory card. Either those that are written or those that are being saved. Restart the camera, transfer the files to a computer and try to view them. If the files are damaged you will not be able to save them. Try to format the memory card, if the error persists you will have to contact your technical service.

Error 20: Mechanical Malfunction

Shutter mechanism error, most likely there is some kind of blockage, error, or disturbance that is preventing the correct operation of the shutter mechanism. In this case, we know that it is not an electronic problem.

Error 30: Shutter malfunction

Unlike Error 20, this one points to some kind of problem with the shutter ... But in this case, it could be a mechanical problem or some kind of electronic communication error.

Error 40: Power supply malfunction

This error indicates that there is an internal error getting power. It is probably due to a battery in bad condition, or poorly charged. Try to reinsert the battery and check that it makes good contact.

How to Remove Scratches From Camera Lens

Error 50: electronic control malfunction

This error is indicating to the user that we are facing an electronic error. However, it does not indicate where the error is.

Error 70: Image malfunction

It may be a memory card writing error, or an image capture error. There may be a simple memory card error, or it may be another problem. But first, it is convenient to rule out the first case.

Error 80: Error in electronic control or image malfunction.

It is an electronic error, which may be related to the capture of the image or to another undetermined assumption.

Solution: The quick fix to fix Canon EOS error codes 10/20/30/40/50/70/80 is to turn off the camera, remove the battery from the camera, wait 15-20 seconds, and then reinstall the battery. Turn on the camera again and check.

Error 99: non-specific error code

In cameras prior to 2007, this error generated a lot of misinformation among users. It was a non-specific error. That jumped like the Check Engine light on cars. It simply meant that something was wrong.

Today Error 99 is a general error and can occur due to several different causes.

Solutions:


Turn the camera off, remove and reinstall the battery and turn the camera on.

If the above solution fails, gently wipe the camera lens and electrical contacts (the area highlighted in red) with a clean, dry cloth.

Gently wipe the electrical contacts and the flash with the help of a clean, dry cloth. Never touch directly with your hands.

Error 60 Trip error

An error occurred when shooting, lens movement may be obstructed. Solution: Check that the camera lens is clear and make sure nothing is obstructing it. After this, turn the camera off and on again.

In the event that the error persists, you should contact your technical service

HOW TO BECOME AN EXPERT IN BLOCKCHAIN

The article was written By Mickael Mosse – Blockchain and Cryptocurrency Expert

The blockchain has become the latest technology that practically everyone talks about: from technical publications to informal conversations in coffee or meetings in the corporate boardroom - it is everywhere.

But if you could stop most people on the street to ask "What exactly is Blockchain? “It is likely that, at most, you got vague references to Bitcoin in response. Now, let's keep the following in mind: Blockchain is touted as the most revolutionary invention since the Internet. Don't you think it's worth learning the basics of what it is and how it works?

Next, we are going to show you a brief section of information about the blockchain and then we will say some instructions on how to become an expert in this technology that is definitely changing the game. Let's go there!

Mickael Mosse Blockchain Advisor

    Mickael Mosse Crypto Advisor

BASIC CONCEPTS ABOUT THE BLOCKCHAIN

Mickael Mosse points out that, One of the biggest misconceptions about the blockchain is that it is synonymous with " cryptocurrency ." The truth is that blockchain is more of a foundation for crypto, it is the technology that underpins Bitcoin(btw)  and other cryptocurrency transactions (sort of like a digital book), and it has wide implications for a variety of modern business practices.

Perhaps the best way to think about blockchain is as a "general purpose" technology, something like a back-end database. It is useful for more than just monetary transactions, it can also be used to track and support a variety of sensitive data streams, such as identity records or contractual agreements. This technology will inevitably spread to sectors like government, law, energy, and healthcare, plus the obvious: finance and banking.

In the not too distant future, Blockchain will probably be a common element of smart contracts, everyday retail transactions, even the way we vote.

Mickael Mosse points out that, The main benefits of this technology and why it is so exciting, is that it is very transparent (every transaction made through the blockchain is open to the public), practically incorruptible (due to its distributed nature) and extremely versatile (as mentioned, btw cryptography). Transactions are only the surface of what can be done with blockchain technology.

All that said, perhaps the second biggest idea about blockchain is that it will irreversibly affect all industries.

Mickael Mosse points out that, Most people talk about blockchain as if it were a magical technology that can transform any business model it touches. Even though it's a wildly exciting technology, it needs to be understood for what it is - a database structure that has some really useful features that are well suited to a number of industry problems.

In other words, blockchain technology itself is not the end of everything for all social and business issues today. However, it can have a great impact on the solutions to those problems. Therein lies its potential.

HOW AND WHY TO BECOME A BLOCKCHAIN EXPERT

According to Mickael Mosse, Blockchain technology is likely to evolve rapidly this year from being "something exciting" to becoming a concrete tool. So why should this matter?

On the one hand, blockchain development is already the second most popular skill in the job market. The Blockchain will quickly become an integral part of many, and perhaps surprising, business models. No matter what sector you are in, there is a great possibility that the Blockchain will have an impact on the way the organization you work for carries out its day-to-day processes.


Therefore, being one of the first people in your company to truly understand Blockchain technology can provide you with a huge advantage on the corporate scale. More generally, the ability to generate ideas about how an emerging technology of this scale will affect your business is extremely beneficial to your critical thinking skillset and can be applied to other disruptive concepts such as artificial intelligence, Machine Learning, the Deep Learning, the Internet of Things, virtual reality, augmented reality, etc. says Mickael Mosse,


In addition to staying on top of the latest blockchain developments through blogs, newsletters, podcasts, or online courses, investing your time in comprehensive Blockchain-focused training will help you truly master this exciting new platform. The right knowledge will make you the “go-to” person on that topic within your organization.

Don't you know what to study to deepen this knowledge and become an expert in Blockchain? The  Expert in Blockchain and Decentralized Applications" course will provide you with the basis to understand cryptocurrencies, blockchain technology systems, and their operation. Technology, Blockchain, and btw Cryptoeconomics are what you need to launch your career, regardless of the sector or industry in which you move. What are you waiting for? This is the year of Blockchain technology, get ahead.

Differences between Bitcoin and Bitcoin Cash

The article was written By Mickael Mosse – Blockchain and Cryptocurrency Expert

Each cryptocurrency has a protocol, operating rules inherent to its chain of blocks. This protocol determines how the validation of transactions is articulated, the incentives for those who validate them, the expected time for each transaction, the size of the block, the tendency to centralization or decentralization, transparency, security, privacy, etc. . The continuation of the blockchain, that is, the production of successive blocks requires the consensus of the full nodes. A full node stores the entire chain of blocks and only archives the new blocks(generated by miners) that are consistent with the determined protocol specifications of a blockchain.

Mickael Mosse points out that, Not all wallets (the software that allows you to access the blockchain and "store" your cryptocurrencies) need to be full nodes, they can simply guarantee that your transfers are in one block by connecting to multiple nodes that accept the same protocol, without having to store all the blockchain. Currently, the Bitcoin Blockchain weighs about 185GB. In this way, other nodes confirm your transactions. The popular Electrum wallet, like most wallets, use this system called SPV ("simplified payment verification").

The Bitcoin consensus works in such a way that if 51% of the full nodes give something for certain, it is true, that is, if 51% of the blocks accept a protocol, this protocol is considered valid in this chain of blocks.

Mickael Mosse Bitcoin advisor

Soft fork & Hard fork

Mickael Mosse points out that, When there is a protocol update, it should be accepted by the majority of full nodes. A soft fork implies an update of the protocol that the community of nodes accepts and is implemented as the new protocol of that same blockchain. In the case of the soft fork, the nodes that have not implemented the update can continue to use the blockchain but without benefiting from the update, however, the blocks mined from that moment must update their mining software so that their blocks are accepted. For example, SegWit is a soft fork that implements a code enhancement to reduce the weight of transactions in the blocks so that each block can validate more transactions.

A hard fork, on the other hand, generates a new chain of blocks, where the old protocol is not valid. When a hard fork occurs, the chain of blocks branches, in such a way that it gives rise to two chains of blocks, two protocols, and therefore two currencies. This is the case of Bitcoin Cash, a hard fork that occurred on August 1, 2017, by the community that did not agree with SegWit and created this fork that expanded the block size from 1MB to 8MB. It should be noted that when a hard fork occurs you do not lose your coins, they are replicated in the new blockchain, so that with your keys you will have the same units in the new blockchain as in the original one at the time of the fork.

Differences between BTC and BCH

According to Mickael Mosse, The fundamental difference between Bitcoin and Bitcoin Cash is in the size of the block. While Bitcoin currently has a block size of 2 MB, Bitcoin Cash currently has 32 MB after a hard fork on May 15 which increased it from 8 MB. The reason for this difference lies in the scalability of the cryptocurrency, those who operated with Bitcoin (btw) when its price was skyrocketing surely remember the high commissions. These work in such a way that miners include the highest commission transactions first.

As the size of the Bitcoin (btw) block is "capped" at 2 MB (previously 1 MB), only a limited number of transactions have space inside (the average transaction weighs about 255 Bytes). A block is mined every 10 minutes, in fact, the protocol is programmed in such a way that when transactions are carried out in less time the difficulty of mining the block increases, and if it takes longer it decreases, giving the average of 10 minutes per block. The consequence of this is clear, a maximum of about 400,000 transactions per day, which is about 3-5 transactions per second. Visa has the capacity to support 50,000 transactions per second. 

Mickael Mosse Blockchain Advisor

This is where the controversial commissions arise, if you want your transaction to be validated earlier, you must pay a higher commission. Depending on the demand for using the network, the commissions will go up or down, so they have an important correlation with the price. It is in relation to this problem where Bitcoin Cash arises, by increasing the size of the block it allows to carry out more transactions per minute then it means lower commissions. In fact, the increase in the popularity and price of Bitcoin Cash coincides with the increase in the commissions of the Bitcoin (btw)  network, as can be seen below.

As can be seen above, if we look at the months and the price variation, the increase in the price of Bitcoin was accompanied by the increase in commissions which in turn was accompanied by the increase in the price of Bitcoin Cash. Below is the Bitcoin Cash / Bitcoin ratio. These relational movements can be used in a simple, cheap, and even leveraged way through CFDs on platforms such as Admiral Markets.

The BTC vs BCH debate

According to Mickael Mosse, The popular debate between these two coins boils down to the debate between immediate scalability (network capacity to support more and more users) (BCH) versus decentralization (BTC). As we have said above, the size of the bitcoin (btw) blockchain is currently about 185 GB, increasing the size of the block or decreasing the average time to mine the block means increasing the speed of increasing the size of the blockchain.

In itself, the size of the chain is not a problem, larger and larger blocks could be implemented to minimize transaction time and thus achieve scalability. The problem lies in who has the capacity to store a chain of blocks that every day increases, for example, 30 GB. Recall that the "voters" of the Bitcoin network are the full nodes that store the entire blockchain. In this sense, the increase in the size of the block is directly an attack on decentralization, which is, after all, the essence of Bitcoin(Remember that it arises as an alternative to fiat money and the monopoly of central banks). Greater decentralization implies a more democratic control of the protocol, as can be seen from what has been said, it also implies a network, in principle, more secure. says Mickael Mosse.

Mickael Mosse Bitcoin advisor

On the other hand, this supposes the inoperability of Bitcoin (btw) as a means of payment at a massive level, since, as we see, there is a tremendous "trade-off" between scalability and decentralization in the short term. However, we must remember that Bitcoin is still in its infancy, it is still an "experiment". In this sense, several decentralized alternatives are being developed for the scalability of Bitcoin, the most famous example is the Lightning Network.

The answer will generally depend on the section or location of the same. In other words, the same size is not used for a photo gallery, an advertising banner or to illustrate a service.

The first thing we should know when we are going to upload an image to our website is the required size. For this, we must look at what are the proportions allowed for that field and select an image that is the required size or somewhat larger. If you do not know where to download photos do not hesitate to read our post on "Image Banks ". neck joint service Next, we are going to explain two ways to cut an image in a simple way, and then we can introduce it on your website.

Once installed we open the image in the program.

In the main menu of the application we select "Scale" (Menu-> Image-> Scale the image). A box with various options will appear. We cut the "Width" and insert the required width and click on height (it is important to keep the chain so that it is trimmed proportionally) and click on "Scale".

At this point, it is possible that "Width" and "Height" coincide, if this is your case goes to the last point, otherwise continue with the following steps.

10 commandments not to be tricked into buying online

When the time comes to enter your credit card number on the Internet, do you have cold sweats, are you hesitating or are you just not doing it? However, this method of purchase is super safe ... provided you know the 10 tips to avoid getting caught online. Many people are asking questions about online business ... here are 10 answers that I present to you in the form of 10 commandments from François to shop on the Web in a safe and intelligent way!

The ultimate advice

Before the 10 commandments ... THE ultimate advice! Never make a transaction via a computer that could be infected with a virus or a public computer. You might have caught a cookie, key sensor, or other shit that retransmits to you-don't-know-what what you type on your keyboard.

Good protection and antivirus suite is the only key to protect yourself.

Think twice also before making a transaction in an Internet cafe or public computer. You do not know if it is well maintained or worse if someone has introduced software for recording what you write.

# 10: HTTPS

To make a transaction on the Web, it must be done on a site offering a secure connection (in https and not in http). The "S" is super important, it is a safety signal. Also, make sure your web browser is up to date. You can check from time to time on their website to make sure.

# 9: Returns and refunds

Take a look at the site's return and refund policy. If the item is defective or broken upon arrival, can you exchange it? How do you get a refund for a purchase? Do you have to reship the package at your expense? Sometimes you have to go to the store to deliver the goods to the merchant at no cost and receive a refund.

# 8: Read!

Take out your glasses and read the fine print!
You never read them, on a regular contract ... and even less on the Web. You are looking for the "next" button and do not read a single line of the legal text of the transaction.
Do not think that you will be able to cry in front of the judge saying "I did not know it", because it will be your fault!
Read the exchange and refund conditions before buying. You will avoid unpleasant surprises if there is a glitch with your article.

# 7: Long live the paper!

Print your transactions or create a file for each transaction. You will have the purchase number, time, and date. This could help you in the event of a confrontation with a company, even a non-fraudulent one because we can go back up in the system to find it. And before a judge, the paper is still much more valuable than an "I swear your honor to you". 

Best online shopping site online shopping bangladesh home delivery you may visit this sitr for a secure online shopping 

# 6: delivery charges

Read carefully to find out how much you will be charged for delivery and keep in mind that if it is in the United States, it is in American dollars and if it is not far from your home, you could pick up your package to avoid fees. Good sites offer you different packages (fast = more expensive and longer time = cheaper). Whether purchased here or elsewhere in another city, province, or country, you should read about the delivery costs.

# 5: Customs

It's fine to pay less for a product bought elsewhere, but in addition to having to validate the exchange rate of our currency, we must look at the side of customs fees.

For a product purchased from Uncle Sam, if the product is manufactured in the United States, you will only pay GST and QST. For other countries, inquire about the customs rate by contacting 1-800-959-2036. It seems so complex that I asked them if we had a cost grid on the Web and I was told that no ... it's too complicated, it is case by case, by product and by country!

# 4: Customs again ...

Customs may equal customs clearance fees. In addition to taking a look at customs fees and delivery costs, you also need to know how the customs clearance of good works.

Several large delivery companies offer free paperwork to get your goods across the Canadian border. Please note ... this depends on the type of delivery (basic package or luxury package!). In one case it's free and in the other ... pay for wanting to save!

# 3: Buy local!

In addition to saving in customs and delivery costs (it is less far away, therefore, cheaper), you will be able to disembark at the merchant's if ever a problem occurs.

Not easy to cry in the office of the company that fooled you in Texas, but much easier to cry in the office a few kilometers from home!

# 2: Read again

Read the privacy policies of the site on which you provide personal information during a transaction.
Several sites will sell your info, share it with partners and you will then receive tons of unwanted emails. Note that the best way to prevent this is to look on the site if it is recognized by the major web security agencies. These sites must guarantee respect for their customers' personal information.

# 1: Your credit card

Ask your company for a credit card with a very small limit that you will only use for your online purchases. In case of fraud, it will be reduced and this will simplify everything with your card company. Note that the regulations are on the consumer side and unless you have shown great negligence, you should not go out too much in the event of a mishap.

The best thing to do is to ask your financial institution what their policy is on the internet shopping and shop for another card if it doesn't suit you.

Also, some sites will offer to save your credit card number to save you time during your next purchase. It is preferable not to use this function: if your profile or the site is a victim of hacking, your banking information will not be affected.

How to become certified in Cisco CCNA 200-301 on your own

The Cisco CCNA certification is one of the most widely recognized for any network administrator. This certification is the first step in the different Cisco certifications and will allow us to expand our curriculum with this globally recognized certification.

Now that we have everything clear with reference to the exam, let's go with the theory. There is a true infinity of books that will prepare you for the exam in a very effective way, we are going to indicate some highly recommended resources to start preparing this Cisco CCNA 200-301 certification that will start from February 2020, although we would recommend not examining the first, and wait until other users put their experience with this new exam through different forums, and thus, prepare it perfectly to pass it.

The first and most important is a study guide which we will find entirely in English, and which will be our base when acquiring knowledge and reviewing our progress. Its name is " CCNA 200-301 Official Cert Guide, Volume 1 " by Wendell Odom.

This new book, written in two different volumes and completely in English, is among the best sellers as far as the Cisco certification study is concerned. With its new edition of the Wendell Odom CCNA Cert Library, which is an official Cisco Systems certificate guide that will help us learn, prepare, and practice to pass the Cisco CCNA 200-301 certification exam.

t is a book written and designed with the clear objective of providing evaluation, review, and practice, which will help us to self-assess ourselves so that we do not have problems against the Cisco written test. At the beginning of each chapter, we will have a small questionnaire that will help us orient ourselves on the time necessary for us to dedicate to each section. Its index of most recurring topics in the Cisco exams will serve as a clear reference, as well as the extra exam preparation exercises at the end of each of the chapters, which will help us delve into the most determining concepts that we must know thoroughly.

In short, this book will help us master all the topics of the new Cisco CCNA 200-301 certification, and will allow us to self-assess our knowledge with the incorporation of real questions from previous exams so that you know in detail what you will find in a real exam. . This book also shares preparation tips, tips to help us identify our weaknesses, and thereby strengthen them before we take the Cisco written test. This guide also has access to video instructions and online hands-on labs, this entire official study guide is designed to guide us to success by ensuring we pass the exam for the current Cisco CCNA 200-301 certification.

The second volume of this book is Wendell Odom's CCNA 200-301 Official Cert Guide, Volume 2.

This is the second volume of the official Cisco Systems Certificate Guide written by Wendell Odom, it is thought in the same way as its first part. It is also officially approved by Cisco Systems as an official study guide. This second volume also expands the online practice lab with more exercises evaluated so that we can continue preparing and improving. With this second volume, we will have our complete certification guide, and we will have a huge basis to pass the Cisco written test without problems, obtaining our valuable Cisco CCNA 200-301 certification.

And as a third reference work we have another highly recommended book, also in English, but required for the preparation of the Cisco CCNA exam, it is called " 31 Days Before Your CCNA Exam: A Day-By-Day Review Guide for the CCNA 200-301 Certification Exam »by Allan Johnson.

The companion learning book " 31 Days Before Your CCNA 200-301 Exam " gives us a simple and practical insight to understanding the Cisco Systems CCNA Routing & Switching certification process. This book helps us put our ideas in order and tackle the 31 days prior to the exam with Cisco Systems certified routines, which will help us polish the last few points we need before facing the Cisco written test. This book breaks down key Cisco exam topics into 31 daily review sessions, using short, concise summaries, organized lists, helpful charts, and contrasting graphical examples.

Recommended web pages to prepare the CCNA certification

With the three previous books, we can prepare for the CCNA certification exam, but at RedesZone we suggest that you go one step further and we leave you a series of pages where you can expand your knowledge even more if possible, although it is possible that some resources that There are on these websites are designed for previous versions of Cisco CCNA, so you should take it into account.

NETWORK CORE

In this free access page, we will learn networking and we can enjoy it completely in Spanish, it has a large number of entries written as a work diary, in which we will learn step by step with practical cases in tools such as GNS3 one of the emulators of most popular networks for their advanced possibilities and configurations.

This page in English is organized by sections and work laboratories, it is also free as well as Network Core, and it offers topic by topic knowledge in CCNA, from beginner level to more complex levels as we advance in the topics that it proposes. Without a doubt, a perfect tool to expand knowledge even from scratch.

NETWORK LESSONS

On this page, we will find content exclusively based on Cisco. It is a page with free content but it has very useful preparatory information for Cisco courses, but for a fee, however, it is a really recommended resource. The content is in English and is presented in learning units for users of all levels.

PACKETLIFE

This page is free and is structured as a blog, many entries, a section for capturing packages, a section for books of interest, very useful to complete knowledge after having acquired a basis with the books and pages that we recommend.

YouTube channels to learn networking and Cisco

Now that we have a base acquired with the books and complemented with pages of knowledge, we are going to continue expanding them with another type of learning, this time based on YouTube. Two channels of the largest communicators in the CCNA area are David Bombal and " DansCourses".

David Bombal has been expanding YouTube with his knowledge for more than 11 years, he is an eminence in the field of the CCNA and CCNP, and through his videos, both practical and theoretical, we will see virtually all the doubts that arise as we acquire knowledge to obtain the CCNA certification. David Bombal also has a website where he teaches courses and solves any questions in a direct communication channel with him, a service that is, for a fee, although in our way of seeing things the hand of a great man like David Bombal is priceless.

DAVID BOMBAY YOUTUBE CHANNEL

discourses have 10 years of experience on YouTube, like David Bombal, he has extensive knowledge in CCNA which he captures in the videos he uploads to this communication channel. It also has its own website where it exposes its knowledge for free and even, ordered by courses and specialty so that you prepare yourself to obtain the official CCNA certification, without a doubt, a huge support to expand knowledge.

DANSCOURSES YOUTUBE CHANNEL

And if we still want to be much better prepared for the challenge of the official Cisco CCNA certification exam, we are going to recommend three courses that you can take online, the first and second courses that we recommend come from the renowned Udemy and taught by Germán Hernández for the Cisco CCNA 200-301 course in Spanish, and by Óscar Leonel for the Cisco CCNA Fácil Theory and Practice course in Spanish.

The first of the following two courses that we recommend are owned by Udemy, who has many courses on its website at very different prices, the first that we recommend is the Cisco CCNA 200-301 Course in Spanish, with a price of 199, 99 euros if you are a Udemy student.

GERMÁN HERNÁNDEZ ONLINE COURSE ON UDEMY

The course, as its name indicates, is focused on the 200-301 certification, just what we want to obtain, it is a course created by Germán Hernández and that already has about 200 students enrolled doing this course, we must take into account that it is a course born recently, the previous certification course, the CCNA 200-125 registered more than 10,000 students studying the creation of Germán Hernández.

The next course, also from Udemy, has an affordable price of 29.99. It is a course that is also taught in Spanish and is designed so that we understand the basis of the Cisco Systems certifications in the CCNA field. With different sections, this course wants to easily prepare us for the 200-301 certification exam and already has more than 550 students enrolled in the course taught by Óscar Leonel. A good starting point, but we recommend this course as complementary training. It is a course designed to expand knowledge when we already have a base.

OSCAR LEONEL ONLINE COURSE ON UDEMY

The last course we are going to talk about is the property of the GNS3 Academy website, it is a paid course, very affordable, yes, only $ 10.89 and in perfect English. It is a course that is also aimed at the three disciplines, 200-125, 100-105, and 200-105, which, although they will be obsolete shortly, this course interests us to expand knowledge and above all, to use the Most important application within the CCNA simulation, GNS3. For this reason, although it is a course that perhaps due to the subject matter we may miss, as an extension and for the price we leave it as recommended. It is a course that is based on practical exercises and with the powerful simulation tool for Routing and Switching GNS3 equipment. Learning to develop in this tool will be of great help to you in preparing for the CCNA exam.

Websites that publish previous Cisco reviews

We have one last step to recommend you, and it is probably one of the most important. On these two web pages, past exam exercises are published and it is very convenient to know the previous questions to learn them in detail since it could make the difference between passing or failing.

9TUT.COM

It is a page with a lot of content, but it highlights its section CCNA 200-125 where it is publishing exercises from previous exams and explained step by step for your entire understanding. It is vitally important to review them, it will help you enormously in your current exam. Completely free and in English. Now we will be thinking that this section no longer serves us since it is the certification that will expire in February, but as you can read in the body of the page itself, as soon as the new certification exams begin, the CCNA 200 category will be opened- 301 and your exams will be published in it.

EXAMCOLLECTION.COM

It is a page where exams are published in full of a multitude of certifications, it is a payment alternative to the previous page, although taking into account what we are risking, it is possible that we do not find it so much what this page asks us monthly as a way of subscription. A much more complete page than 9tut and also in English, so we strongly recommend that you visit this page to prepare well to pass the exam and obtain the official Cisco CCNA certification. As in the previous case, this page will also have the exams for the new certification as soon as they begin to impose them on the new applicants.

That is all we can suggest for you to prepare for the exam yourself, from RedesZone we hope that all these indications help you and you can take the exam for this Cisco CCNA 200-301 certification with guarantees to pass it.
