hallo guys today in this class we well lern about mobile app development so let’s start this class
we first take an overview deck of this class, we are going to get:
and many more….Toh stay in class till the end
Certified Cisco Network Associate (CCNA) is a certification course offered by Cisco. Cisco is a leading vendor of IT network equipment, which is designed and manufactured in-house. As the largest OEM in their field, Cisco has the highest market capture of any IT vendor, and Cisco products are used almost universally in business and industry.
1. What is the CCNA Certification?
A CCNA certification validates the skill, ability and expertise of an individual to fix, configure and troubleshoot networks. CCNA is the basic course that lays the foundation for Network Engineers, and once the basics are in place, after doing the CCNA, even other vendors consider it reputed, like Juniper, HP and Dell, to name few.
As businesses around the world rely on IT services to operate efficiently and profitably, CCNA professionals operate at the technical end, ensuring adequate performance of Network devices such as routers, switches and firewalls.
The CCNA certification has evolved through the years. Originally, there was only one CCNA certification. In 2013, the areas of the certification were expanded, to serve the growing demand for Cisco-certified professionals that has accompanied the growth in ecommerce and increasing reliance upon data centers.
Currently, there are certifications within the CCNA focusing on such areas as:
- Routing and Switching
- Service providers
- Data centers
The CCNA gives you an insight into all flavors of the set of Cisco certifications, and once a person has completed CCNA, they would be in a better position to decide further which domain to choose for the next level, based on industry requirements and interest. Generally, CCNA Routing and Switching is the basic credential to obtain, after which one can proceed with the others mentioned below:
- Service providers
- Data centers
2. What Is The Accreditation Body For The CCNA Certification?
A certification is only as good as the accreditation behind it, lending it credibility, and CCNA has among the best organizations in the businesses backing it. A world leader in networking, Cisco’s business operates with the aim of transforming how people communicate and collaborate, manufacturing the vast majority of IT communication equipment in use, today. The CCNA certification is thus globally-recognized and well respected.
3. Who Is Eligible For The CCNA?
Interestingly, there are no formal requirements for a person to meet to be eligible to take the CCNA exams. CCNA certifications thus are a very attractive option for a fresh graduate to pursue, since companies also hire Network Engineers who are CCNA certified, irrespective of level of experience.
4. How To Get Certified
In order to get certified, a person must pass specific exams related to the CCNA certification. They can obtain the passing grades on either:
- ICDN1 (100-101) or the ICDN2 (200-101) Exams
- Combined CCNA (200-120) Exam
Registration for these exams can be done through Cisco directly or with the help of a qualified CCNA training partner like Simplilearn.
Pearson Vue is the authorized testing partner to conduct CCNA certification exams. They recommend registering for the test at least 2 days prior to the date that is planned for the test as the slots are limited and are booked on a first-come, first-served basis. The registration can be done by phone or online. Payment for the tests are due when registering for them. It is recommended to arrive at the testing location for the test at least 45 minutes ahead of time.
In order to pass the exams, the candidate will need to score 80% or above.
5. Getting The Right Training For The Certification
Attempting to take the exam, regardless of level of experience, with no prior training would be ill-advised. Aspirants who undergo certified training with experienced training providers such as Simplilearn stand a better chance of clearing the exam first time out.
Simplilearn’s CCNA training course offers 20 hours of high-quality eLearning content, 2 CCNA simulation exams, a comprehensive glossary, and assistance with scheduling your exam with Pearson Vue.
There are plenty of different programs that vary in mode of delivery, length, and effectiveness. It is up to the individual to make sure that they choose a program that will work for them.
Make sure to consider these factors when choosing a training program for the CCNA certification.
- Location – It is important to choose a location for the training that is convenient. Community colleges and other technical schools offer these types of classes. They can also be found online.
- Program Length – The length of the program can be anywhere from a few days to as long as a person needs to prepare for the exam. There is no specific length that is best, as long as all of the necessary material is covered.
Important information – A good training program will cover the following areas:
- WAN and LAN design
- OSI models
- IP addressing and Subnetting
- VLAN and WLAN
- Routing protocol
- Switching Concepts
- Network Address Translation
- Network Security and management (ACL included)
- VOIP Basics
- Wireless Essentials
- Routers, Switches, Firewall and Data center Introduction.
6. Is Training Enough, Or Is post-Training Preparation Necessary?
Although training sheds light on what is expected of the candidate in preparation for a particular exam, it cannot possibly cover all topics that may be asked on the exam. A candidate should therefore work on enhancing their knowledge on the outlined topics listed above to ensure all areas of CCNA are covered through self-study.
A single source or method of study is not always sufficient to pass the exams as the technology domain is complex, dynamic, and continually advancing. Therefore, the candidate should always endeavor to keep up-to-date with the technological advancement in the environment as they look to expand their knowledge. For more information about what people are doing to prepare for the CCNA certification exams, consider participating on various CCNA forums on the internet to see what’s new and what’s hot.
7. Exam Structure
In order to prepare well for the exam, it is essential to know what to expect. Each CCNA exam is a little different from the one before, and is usually delivered in one of the following formats:
- ICDN1 – This exam consists of between 40 to 50 questions and a person has 90 minutes to complete it
- ICDN2 – This exam consists of 40 to 50 questions with a time limit of between 75 and 90 minutes
- Combined CCNA – This exam consists of 45 to 55 questions and has a 90 minute time limit
The tests are designed to assess the individual’s ability when it comes to installing, configuring, and troubleshooting network systems. The certification is valid for 3 years once the exams have been passed with a score of 80% or above.
8. What if one fails to pass the exam in one go?
Like any other certification exams, not everyone will pass on their first try. Statistics show that it takes people an average of 3 times to pass the test. There are no limits on the number of times that a person can take the test. Hence, it is important to practice with a good partner like Simplilearn. The other thing to consider is the cost of taking the test. At nearly $300 per test, retaking it multiple times can be a problem for some.
9. How does the CCNA Certification Help Career Growth?
The CCNA certification is among the most respected certifications in the industry. It can open up new opportunities for higher positions and more money. As per statistics, the average salary hike upon obtaining a CCNA certification is about 20%.
10. Post Examination Requirement
Once a person has obtained the CCNA certification, they need to ensure that they put the acquired skill to test in day-to-day activities. Being recognized as a part of the Cisco certified Network is something that a person should be proud of. Seeking out other like professionals and networking is also a good way to continue learning about Cisco Network systems.
As the technology involved changes rapidly, networking with other IT professionals can help a person stay up to date as they work to maintain their certification standard and prepare for their next steps that could include other associate level certifications from Cisco.
Taking the CCNA exams requires knowledge and commitment, but the rewards are worth the effort. Given the intense competition in the IT networking field, the only way to stand out from the crowd and get your resume noticed is with a professional certification that validates your skills and goes a long way toward demonstrating commitment to the employer.
As Tom Hanks said back in the movie Forrest Gump, “It happens”. Almost every time I chat with someone new around the “so whatta ya do for work” question, my side of the conversation commonly comes around to the CCNA exam. And when the other person is an IT person who knows anything about CCNA, 4 times out of 5 – without any prompting from me – they comment about how it’s a tough exam to pass, especially for an entry level cert. And that’s not just from what they’ve heard or experienced about newbies to Cisco – I’ve met many people with a fair amount of Cisco experience, or who were former CCxP certified folks, who found CCNA difficult. And a lot of people who’ve recertified by taking CCNA again have told me that they were surprised how much harder the test was than when they had passed it 3 years ago. So as Mr Gump says, it happens – these dangling comments, the reasons why they think it’s a hard test to pass.
Well, I’ve not done much posting about CCNA specific topics in quite a while… so here we go. Today I’ll look at some of the root causes of the difficulty, focusing on preparation before the exam. Next class , I’ll look at the exam itself, and why the exam is a challenge. Then I’ll bridge into some discussion of what to do about those challenges in the coming class . Your job – tell me why you think CCNA is a difficult exam, or why you don’t. And as always, make sure to not break Cisco’s NDA when posting about an exam. 😉
First, a few background comments. If you’re considering CCNA, don’t let my first few words of this class
scare you away from CCNA. Lots of people study and pass. But if you’re thinking that CCNA would be a quick entry-level cert to get, you might want to take a closer look.
Next, CCENT (www.cisco.com/go/ccent) is officially Cisco’s entry level cert, but in practice, CCNA functions more as the entry level Cisco cert. Most (if not all) of the associate and professional level Cisco certs require CCNA and not CCENT; in fact, even the CCNA specializations (eg, CCNA Voice) uses CCNA, not CCENT, as the prereq. So for now, I’ll focus on CCNA, and in particular, the single-exam path to CCNA: the 640-802 exam.
Now to what I really want to discuss today: why CCNA is difficult.
First, consider the prep time before the exam. CCNA is a big set of topics today. My two book CCNA Exam Cert Guide set, if you ignore the pages for front matter and back matter, totals to over 1200 pages. (OK, I do have a rep for being “thorough” in my books, but that’s still a lot.) The authorized Cisco courses for CCNA total 10 days of classroom time – and frankly, I think most people still need to study after those classes to be ready to pass the 649-802 exam., The rest of the associate and professional level certs essentially cover a single 5-day class’s worth of material, with a few exceptions.
The size of coverage results in two underlying issues in my opinion. First and more obvious, the study time required to be ready for the test. Second and less obvious is the forget-before-the-exam issue. If you’re diligent, and take 10 hours a week to study CCNA (quite a bit of time per week for most folks), you may need 10-15 weeks of such effort to read books, watch videos, discuss in communities, take practice exams, practice subnetting, practice hands-on skills, review, etc. In that time, some of the early reading may just fall out of your memory. Then you need more review, which takes more time, viscous cycle, etc etc.
Next, I wonder how much the monetary cost impacts the preparation. Most people purchase multiple tools to prepare, and use many free resources. Usually, scrambling around to find free resources costs a little more time, but you might save a few bucks. And there’s a ton of CCNA products out there, including several with my name on them. You could spend many hundreds of dollars beyond the your base study book(s), on videos, gear or simulators, practice tests. How much of that stuff you need depends in part on the person, but I’m thinking that some people take the test, and think that maybe buying/using one more study resource may have made the difference. (Any anecdotes on that in particular? What did you, in retrospect, wish you had done more when prepping for CCNA?)
Certainly, taking a CCNA class can really help you prepare for the exam. Classes typically cost well past $1000 US, making them out-of-reach for a lot of people whose companies are not footing the bill. It makes me wonder how many people feel like that their (lack of) budget really impacted their ability to prepare for CCNA.
The third and last exam prep issue I’ll bring up today is the whole question of knowing when you are ready to have a reasonable shot at taking and passing the 640-802 exam. It’s a bit of chicken and egg problem because it is a first Cisco exam, so it’s more difficult to know if you’re ready. (For those of you in this particular boat right now, take a look at the sample of the exam interface.) But I think that a lot of people gauge their readiness using the exam software and exams, but that’s a tough way to gauge your readiness. But using practice exams may be the best we have, so let me comment a bit.
First off, the actual CCNA has many hidden details that we don’t know about grading. Are all multichoice questions equal? Are all Sims equal? Are Sim questions graded with partial credit (answer is yes from what I’ve heard in the past). In a testlet with 4 subquestions, how does that compare to a single multiple choice question as far as points go? How do they decide how many questions you get, which then impacts how much time pressure exists? We don’t really know.
Next, compare that lack of knowledge about the exam to the test-taker strategy of taking a “sample CCNA exam” with whatever exam software you use. For instance, with my CCNA ECG books, the CD in the back has practice questions (supplied by the publisher, often times by me for my own books), and exam software from Boson (www.boson.com). You can take a “sample CCNA exam”, timed, and get a score. You might take those tests to help decide whether to take the actual exam now, or wait a few more weeks for more study.
However, it’s difficult for those building the exams to make such a practice exam match up to the real exam experience because of all the hidden details about scoring. Even if a particular exam used questions that match the same level of difficulty as the actual exam – not always easy to do, by the way – getting the right mix into a single mock exam is difficult because of the hidden scoring details. So if you pass the practice exams with high scores, it may mean you’re ready. Unfortunately, it might also mean that the practice exam had easier questions, or not enough of the longer application questions so that oyu didn’t have time pressure, or not enough Sim/Simlet questions, or you had seen some of the questions when using the software before, skewing the results. Or, you could fail, or barely pass, but have actually been ready a month ago, with the opposite factors.
So, what do you do to gauge whether you’re ready for a Cisco exam? Is the “passing the sample exams” measure your primary gauge? Or is it something else?
That’s it for today. So, what amI leaving out, for preparation issues that make passing CCNA difficult? What’s your biggest hang-up? Weigh in on the following survey as well.
