Correct Answer: 1721600 through 17231255255
Correct Answer: 10000 through 10255255255
Correct Answer: Loop back or diagnostics
Correct Answer: Proxy ARP
Explanation:
Proxy ARP can help machines on a subnet reach remote subnets without configuring routing or a default gateway.
Correct Answer: 10xxxxxx
Explanation:
The range of a Class B network address is 128 - 191. This makes our binary range 10xxxxxx.
Correct Answer: Dynamic Host Configuration protocol (DHCP) provides network configuration information (including IP address) to hosts, eliminating the need to perform the configurations manually Domain Name Service (DNS)resolves hostnames - both internet names such as wwwroutersimcom and device names such as workstation 2 to IP addresses, eliminating the need to know the IP address of a device for connection purposes
Correct Answer: /30
Explanation:
A point-to-point link uses only two hosts. A/30, or 255.255.255.252, mask provides two hosts per subnet.
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: 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: 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.
