Chapter 8 quiz

A college has five campuses. Each campus has IP phones installed. Each campus has an assigned IP address range. For example, one campus has IP addresses that start with 10.1.x.x. On another campus the address range is 10.2.x.x. The college has standardized that IP phones are assigned IP addresses that have the number 4X in the third octet. For example, at one campus the address ranges used with phones include 10.1.40.x, 10.1.41.x, 10.1.42.x, etc. Which two groupings were used to create this IP addressing scheme?

-geographic location -device type

What are two benefits of subnetting networks?

-reducing the size of broadcast domains -grouping devices to improve management and security

Three methods allow IPv6 and IPv4 to co-exist. Match each method with its description. 1, The IPv4 packets and IPv6 packets coexist in the same network. 2, The IPv6 packet is transported inside an IPv4 packet. 3, IPv6 packets are converted into IPv4 packets, and vice versa.

1, dual-stack 2, tunneling 3, translation

62

A network administrator has received the IPv6 prefix 2001:DB8::/48 for subnetting. Assuming the administrator does not subnet into the interface ID portion of the address space, how many subnets can the administrator create from the /48 prefix?

65536

What does the IP address 192.168.1.15/29 represent?

broadcast address

Three devices are on three different subnets. Match the network address and the broadcast address with each subnet where these devices are located. Device 1: IP address 192.168.10.77/28 on subnet 1 Device 2: IP address192.168.10.17/30 on subnet 2 Device 3: IP address 192.168.10.35/29 on subnet 3

subnet 1 network address: 192.168.10.64 subnet 1 broadcast address: 192.168.10.79 Subnet 2 network address: 192.168.10.16 subnet 2 broadcast address: 192.168.10.19 subnet 3 network address: 192.168.10.32 subnet 3 broadcast address: 192.168.10.39
