Correct Answer: 127.0.0.1
Explanation:
To test the localstack on your host, ping the loop back interface of 127.0.0.1
Correct Answer: Router(config)#ip subnet-zero
Explanation:
A Class C subnet mask of 255.255.255.224 is 3 bits on and 5 bits off (11100000) and provides 8 subnets, each with 30 hosts. However, if the command ip subnet-zero is not used, then only 6 subnets would be available for use.
Correct Answer: 30
Explanation:
A/27 (255.255.255.224) is 3 bits on and 5 bits off. This provides 8 subnets, each with 30 hosts. Does it matter if this mask is used with a Class A, B, or C network address? Not at all. The number of host bits would never change.
Correct Answer: /all
Explanation:
The /all switch must be added to the ipconfig command on a PC to verify DNS configuration.
Correct Answer: Smaller routing tables
Explanation:
Route aggregation results in smaller routing tables.
Correct Answer: tracert
