Which of the following are benefits of route summarization? (Choose three) A. Lower use of IP addresses B. Smaller routing table C. Improved convergence D. Fewer routing updates Correct. Route summarization reduces the size of routing tables because only one summary route is received by the destination router. Incorrect.

How can this impact performance? A. It may lead to a situation in which the network needs more time to detect potential failure with a longer convergence time B. It could lead to high utilization of the link with routing traffic C. It will automatically increase the hold time for the AS To improve performance, EIGRP timers can be manipulated. Which of the following statements are true? (Choose three) A. Mismatched timers can lead to neighborship flapping B. Timers between neighbors need to match C. Timers between neighbors do not need to match D. Changing EIGRP timers can improve network convergence Correct. Hello and hold timers can be changed to help with convergence. A good ratio for this is 3:1. Incorrect. Timers do not need to match. However, mismatched timers could lead to instability. Correct. Timers can be different. However, asymmetrical timers may lead to flapping EIGRP neighborships and network instability. Correct. Mismatched timers can cause problems. For example, if one side of the link has a hello interval set to 5 seconds with the default hold time set to 15 seconds, and the other side has a hello interval set to 30 seconds, the routers will establish a neighbor relationship for 15 seconds and then it will be down for the next 15 seconds.
