G. 171.15.66.0/28
H. 171.15.66.234/32
2. True or false: IPv6 addresses are in short supply.
A. True
B. False
3. True or false: using DHCP is the only way for a host to obtain an IP address today in the Internet.
A. True
B. False
4. True or false: because it uses a link layer broadcast, in order to receive a response a node using DHCP must be on the same link as its DHCP server.
A. True
B. False
5.. True or false: because DHCP uses link layer broadcasts, the IP gateway for a subnet must also be a DHCP server.
A. True
B.False
6. DHCP is a layer 3 (network layer) protocol
A. True
B. False
7. Mark all of the following that are syntactically valid IPv6 addresses:
A. 2001:470::806d:1::9
B. 64:ff9b::171.66.3.9
C. 65:aagg:54::22:12.44.11.99
D. dead:beef:10:10.44.12.22::9
E. fe80::6aa8:6dff:fe05:8522
F. fe80::213:72ff:fe4c:d96a
8. True or false: It is considered good practice for Network Address Translators to map a single external IP/port pair to multiple internal IP/port pairs.
A. True
B. False
9. True or false: Network Address Translators cannot be layered. I.e., if you have two layers of NAT between a pair of hosts, all IP communication will break.
A. True
B. False
P.S. I don't know why it don't have a proper spacing. :(
Explanation / Answer
Answer:
1. C 171.15.0.0
Siince 171.15.66.234 is a class B IP address , it will divide the octets into two parts , first two parts for the network and the other for host
2. B. False
IPV6 is the standard version of ipv4 . IPV4 was used before but ipv6 is introduced to handle the faults remainded because of ipv4.
3. B FALSE
RARP is another way to obtain the IP address of the host by sending broadcast request to all the hosts in the network layer with the host's MAC address.
6 . True , it works on the network layer.
7. A. 2001:470::806d:1::9
E. fe80::6aa8:6dff:fe05:8522
F. fe80::213:72ff:fe4c:d96a
