CCNP BCRAN Self-Study: Managing Network Performance with Queuing and Compression

  • Sample Chapter is provided courtesy of Cisco Press.
  • Date: Dec 23, 2003.

Chapter Description

To help you prepare for the CCNP BCRAN exam, Brian Morgan and Craig Dennis discuss some of the advanced queuing techniques offered in Cisco IOS and compression techniques that are possible from Cisco routers.

Q&A

The questions and scenarios in this book are more difficult than what you will experience on the actual exam. The questions do not attempt to cover more breadth or depth than the exam, but they are designed to make sure that you know the answer. Rather than enabling you to derive the answer from clues hidden inside the question itself, the questions challenge your understanding and recall of the subject.

Hopefully, mastering these questions will help you limit the number of exam questions on which you narrow your choices to two options and then guess.

The answers to these questions can be found in Appendix A.

  1. Where on a router is queuing implemented?

  2. When should queuing be considered a viable implementation?

  3. Should a queuing strategy be implemented on all WAN interfaces?

  4. When is WFQ enabled by default?

  5. How does CBWFQ differ from WFQ?

  6. What is the Cisco IOS command to select and sort traffic into various flows in CBWFQ?

  7. What is the Cisco IOS command to assign a policy to one or more flows?

  8. What makes LLQ more detailed than CBWFQ?

  9. What command is used to create LLQ from a CBWFQ configuration?

  10. What is the actual Cisco IOS command to match all traffic from subnet 10.1.1.0 /24 to network 192.168.1.0 /24?

  11. What are the actual Cisco IOS commands to match the access list in question 10 into a single group or flow?

  12. What are the actual Cisco IOS commands to apply a policy that states that "traffic will get 48 kbps during congestion" to the previous flow?

  13. What are the actual Cisco IOS commands used to apply the policy in question 12 to interface serial 0/0?

  14. List the types of compression supported by most Cisco routers.

  15. When should link compression be implemented?

  16. Which type of compression should be utilized on VC-based WAN deployments?

  17. What are the two link-compression algorithms, and which one is considered an open standard?

  18. When is TCP header compression most effective?

  19. When can TCP header compression be implemented?

  20. What compression options are possible across a Frame Relay link?
