Frequently Asked Questions and Myths
FAQ
What changes have been made to the associate-level certification programs offered by Cisco?
Cisco declared on March 26, 2013, that it was planning to update or redesign the associate-level certification programs. This includes the CCNA and Cisco CCENT certifications. Cisco works on restructuring these courses to ensure that the course material is aligned with the changes in the technology in the routing and switching industry. The course material for these courses also includes advanced switching and routing technologies, including security, remote, and voice. This certification was previously called the CCNA Certification and has now been broken down into multiple segments, and one segment is the routing and switching certification.
Additionally, most associate-level examinations, including the CCNA Voice, CCNA SP Operations, CCNA Security, and CCNA Wireless examinations, consider the CCENT Certification as a prerequisite. You should visit the Cisco Learning Network to learn more about these associate-level certifications. This network will also help you learn more about the numerous changes that are made to the syllabus.
Are there changes being made to the CCNA Routing and Switching Exam?
Cisco has split the CCNA certification into the ICND1 and ICND2 examinations. Cisco has included the following topics in the syllabus for the certification: IPv6, investigating, and the most recent Cisco routing and switching technology and software. Cisco, as mentioned
earlier, always includes newer concepts in the syllabus since improvements and advancements are being made in this industry. The exams 640-816 ICND2, 640-822, and 640-802 will now be replaced by the 200-101 ICND2, 100-101 ICND1, and 200-120 CCNA respectively.
Why have so many new topics been included in the CCNA and CCENT Routing and Switching exams?
Numerous Cisco clients across the globe have affirmed that they require every employee with a Cisco certification, especially a CCNA certification, to have better abilities and knowledge. To accommodate this request, Cisco has moved a few subjects from the ICND2 certification to the ICND1 certification examination. If you pass the ICND1 test now, you will undoubtedly have better skills and more knowledge when compared to a student who passed the previous ICND1 examination.

Myths About CCNA
An issue with the Internet is that it gives some people the power to spread incorrect information about anything. The Internet also allows rumors and incorrect information to spread quickly. The fact is that the story is always exaggerated as it moves from one platform to the next, and the CCNA examinations are no exception to this. There are a few myths about the CCNA and CCNP examinations that have been covered in this section.
The questions you are asked in the exam are based on the survey that you fill out at the start of the exam.
Every student is required to complete a survey before he or she begins the test. This survey will ask the candidates about the different topics they are comfortable with and also talks about some technologies that they are comfortable with. It is difficult to rate yourself ISDN, Frame Relay, and other technologies since you are about to take an examination that covers those topics. Therefore, it is possible that you may worry about how the questions will impact
your examination. The truth is that your answers to the questions in the survey do not matter. There are some forums and posts on the Internet, which will tell you that you must always rate yourself excellent on any topic that is being asked. This is because they believe that the questions asked from that topic will be easy for one to cover. If you lower the rating, the difficulty of the questions asked from that topic will increase. Cisco has debunked this myth, and you mustn't read too much into the questions asked in the survey. You should not worry too much when you are filling out the survey.
When you answer a question incorrectly, the exam will ask you questions from that topic until you get one answer right.
Cisco does not follow the pattern of adaptive testing in any of the certification examinations that it conducts. All the questions asked during the examination will be taken from a large question base. If you have appeared for the Novell examination or the GMAT, you will understand what I mean by adaptive testing. Therefore, CCNA examinations are not nerve-wracking.
Your answer will be marked wrong for the simulator questions if you include an extra command.
Both the CCNA and CCNP examinations use the simulator engine. This engine will only act like a router or a switch. Therefore, you can use some extra commands during the examination. You will be given instructions and information about the engine that you are using before the exam. Remember to relax and try to configure the switch the same way you did when you were practicing your labs.
Once you walk into the examination room with a combination of the required knowledge, the troubleshooting skills, theoretical and practical knowledge, and hands-on experience, you can pass your exam. Do not let what some people believe about the examination deter you from applying.
Things to Keep in Mind
CCNA is a comprehensive exam
Regardless of which CCNA certification you appear for, you will notice that the questions are spread across the different topics covered in the syllabus. You will see that the questions are not only based on TCP/IP topics but also cover questions on how routing protocols can be used to span trees. There is a lot to cover in the CCNA examination, and it is for this reason that the exam is deemed to be difficult. Instructors and experts state that every candidate should always focus on the ICND subjects if they wish to create a foundation for themselves. This means that you will need to understand everything in the material for those exams.
The CCNA exam is very quick
The CCNA examination is very quick in the sense that you only have ninety minutes to answer sixty questions. It is very difficult for anybody to answer those many questions in a short period, but if you are well prepared, you can zoom past the questions in no time. You must remember to focus on your training and experience. Most of the questions in the examination will focus on real-world problems.
The Cisco Networking Fundamentals
The CCNA Routing and Switching Certifications will teach you about the different fundamentals of Cisco networking if you are looking to work in that field. This certification focuses on foundational IP networking skills. It also teaches individuals how to troubleshoot any issues. A CCNA certification will help you learn more about designing and configuring LAN switches, identify basic threats, configure IP routers, install and verify the basic IPv4 and IPv6 network, understand topologies, configure EIGRP, connect to a WAN, configure OSPF in IPv4 and IPv6, understand network issues and wide area of the technologies, understand device management and Cisco licensing.
