To determine best path,routers use metrics such as the value of the first octet of the destination IP address.

Question 19

Which of the following is a command you would find in an antispoofing ACL for network 172.31.0.0/16?

D) permit icmp any any redirect

Question 20

Some methods of attacking a Cisco router do not require knowledge of the IOS version,so software patching is recommended.
