1.What are the parts of an IPv4 address? (Choose two.)
A. Host
B. Network
• A, B. An IPv4 address is a hierarchical address that is made up of two parts: a network portion and a host portion.
2. What is the purpose of the network address?
B. To refer to a network
• B. The network address is a standard way to refer to a network.
3. What are characteristics in common among unicast, broadcast, and multicast IPv4 communication? (Choose two.)
A. The source address is always a unicast address.
C. There are never multiple destination addresses in the header.
• A, C. For all three types of communication, the IPv4 address of the originating host is placed in the packet header as the source address, and there is only one IP source and destination address.
4. Which of the following addresses IPv4 would be used in a private network?
A. 240.23.56.12 B. 192.0.1.12 C. 127.27.20.10 D. 192.168.1.1 E. 169.254.72.6
• D. The private address blocks are 10.0.0.0 to 10.255.255.255 (10.0.0.0/8); 172.16.0.0 to 172.31.255.255 (172.16.0.0/12); and 192.168.0.0 to 192.168.255.255 (192.168.0.0/16).
5. What is the principal reason for the development of IPv6? _________________________________________________________________
• The need for more address space is because of the exhaustion of the IPv4 addresses.
6. How are IPv6 addresses represented?
C. 8 hextets separated by colons
• Hextet is the unofficial term used to refer to a segment of 16 bits or four hexadecimal values. An IPv6 address requires 8 hextets to represent the 128 bits.
7. What type of IPv6 address should be used for communication that is limited to a single network segment?
B. Link-local
• B. An IPv6 link-local address enables a device to communicate with other IPv6-enabled devices on the same link and only on that link (subnet).
8. What methods automatically provide global unicast addresses? (Choose two.)
A. SLAAC B. DHCPv6 C. ICMP D. DAD E. ANDing
• Two ways in which a device can obtain an IPv6 global unicast address automatically are Stateless Address Autoconfiguration (SLAAC) and DHCPv6.
9. Which type of IPv4 address allows a host to send a message to a group of hosts?
A. Unicast B. Multicast C. Broadcast
• Multicast is used to send a single IPv6 packet to multiple destinations.
10. What protocol is used in IP networks to verify connectivity? _________________________________________________________________
• ICMP Both IPv4 and IPv6 use an ICMP protocol as the principal means to verify connectivity.
11. What utility is used to identify network path between hosts?
A. DHCP B. Ping C. Multicast D. Traceroute
• Traceroute (tracert) is a utility that generates a list of hops that were successfully reached along the path.
