Correct Answer: The first network in the block
Explanation:
The network address used to advertise a summary address is always the first network in the block
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: 200.10.5.64
Explanation:
This is a pretty simple question. A/28 is 255.255.255.240, which means that our block size is 16 in the fourth octent. 0,16, 32, 48, 64, 80, etc. The host is in the 64 subnet.
Correct Answer: DNS
Explanation:
The most likely problem if you can ping a computer by IP address but not by name is a failure of DNS.
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
Explanation:
tracert is the Windows version of the Cisco command that displays the networks traversed on a path to a network destination.
Correct Answer: arp -a
Explanation:
The arp -a command displays IP-to-MAC-address mappings on a Windows PC.
