Question 2

[am4show have=’p2;’]Which feature automatically disables CEF when it is enabled?

A. RIB
B. ACL logging
C. multicast
D. IP redirects

 

Answer: B[/am4show]

Explanation

ACL Logging means to use the “log” or “log-input” parameters at the end of the ACL statements. For example: “access-list 100 deny icmp any any echo reply log-input”. In either situation, remember that using either of these two parameters disables CEF switching, which seriously impacts the performance of the router.
