Q&A

The questions and scenarios in this book are more difficult than what you should experience on the actual exam. The questions do not attempt to cover more breadth or depth than the exam; however, they are designed to make sure that you know the answer. Rather than allowing you to derive the answers from clues hidden inside the questions themselves, the questions challenge your understanding and recall of the subject. Hopefully, these questions will help limit the number of exam questions on which you narrow your choices to two options and then guess.

You can find the answers to these questions in Appendix A.

1.	Where is the most appropriate place to connect a block of enterprise (internal) servers? Why?
2.	How can you provide redundancy at the switch and core block layers? (Consider physical means, as well as functional methods using protocols, algorithms, and so on.)
3.	What factors should you consider when sizing a switch block?
4.	What are the signs of an oversized switch block?
5.	What are the attributes and issues of having a collapsed core block?
6.	How many switches are sufficient in a core block design?
7.	What building blocks are used to build a scalable campus network?
8.	What are two types of core, or backbone, designs?
9.	Why should links and services provided to remote sites be grouped in a distinct building block?
10.	Why should network-management applications and servers be placed in a distinct building block?
