In the second module, you learned about Cisco’s information model, which is a modeling framework for the exchange of logically addressed resources. You created logical flows using an IDispatch utility and a text processing system. The result is a logical extract from an IP packet that encapsulates the IP packets. An extract can be stored as a compact form of a Tagged Image with an I-record extension. A Tagged Image is also called a payload for the purpose of transport.

In module 3, you needed to demonstrate your understanding of how an IP packet is classified as an ICMP echo request, ICMP Echo reply, or ICMPransmission. Cisco creates three types of IP packets: normal, urgent, and error. There are different types of protocols involved in sending these packets and they are: SBC packet, BSN packet, and QoS packet. Each type has a different protocol specification and is presented differently on different exams. So, we need to have at least one expert in our team who is competent in answering all these Cisco certification questions.

If you want to get the answers to all these questions quickly, you can take Cisco certification practice tests. These Cisco exams were designed to test your understanding and skills in the areas covered in the exam. Although it does not guarantee you passing, these exams will definitely get you prepared. Remember, however, that you need to study and practice if you want to excel in this field. It is not just about reading a book.

The exam questions differ depending on the level of your Cisco certification. There are specialized exams for those who have just recently earned their CCNA or CCIE certifications or for those who have been doing the same for several years already. Of course, you need to take the right amount of time to study in order to excel in this field. Here are some sample Cisco certification questions that you will surely face on your Cisco certification exams:

o What is a router? routers are hubs in a network that contains many other routers, all of which link up to one central hub where the traffic goes through. You need to know what a router is and its major role in a computer network.

o How does packet delivery work? Packet delivery is the way how data arrives in a computer system. This is one question that might be quite difficult to answer given the many types of packet transmission mechanisms available today. For this reason, you need to do a lot of practice so that you get an accurate grasp of packet delivery.

o What is a switch? Switches are devices that allow you to create different configurations within a single network. One type of switch is the device that allows you to create a virtual private network. Another type of switch is the device that allows you to create a routing table. Cisco exam questions on these switches will help you understand how these switches work.

c. Do you know what a VPN is? A VPN is a type of data link that allows multiple devices to connect to the same network without the physical need to go through a centralized server. Cisco certification questions on VPNs will provide you with a thorough understanding of this technology. You need to have a comprehensive grasp of this technology if you want to pass this exam.

d. Why is a CCNA exam so important? The reason why CCNA certification is so important is because it allows you to have a leg up on the rest of the workforce when it comes to working in the networking space. Without certification in this technology you will find that networking professionals will simply assume that you are not qualified to work in their industry. When you take a CCNA exam your certification shows prospective employers that you have been trained in this particular area. Your willingness to learn and your desire to stay up to date with the latest technologies are great reasons to get a CCNA certification.

e. Who should take Cisco certification exams? Cisco certification questions are designed for all types of people. If you want to get started in the networking world, you will likely be able to pass the exam with little difficulty. On the other hand, if you have experience working as a network engineer in the public or private sectors you will likely need more of a tutor to help you prepare. Either way, anyone can pass these exams.

f. Who should not take Cisco certification questions? First of all you need to make sure that you have the mental capacity to understand and answer any question that you may face on a Cisco exam. Secondly, if you do not know what you are doing chances are you will not study very hard. So, before taking an exam to make sure that you are willing to put in the time necessary to answer any questions that you may have.
