Chapter 8 Netacad

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? (Choose two.)

• support model

• department

• device type

• geographic location

• personnel type

Fill in the blank.

The last host address on the 10.15.25.0/24 network is

• 240

• 128

• .254

• 254

A network administrator subnets the 192.168.10.0/24 network into subnets with /26 masks. How many equal-sized subnets are created?

• 2

• 6

• 1

• 4

An administrator wants to create four subnetworks from the network address 192.168.1.0/24. What is the network address and subnet mask of the second useable subnet?

• subnetwork 192.168.1.8

  subnet mask 255.255.255.224

• subnetwork 192.168.1.64

  subnet mask 255.255.255.192

• ubnetwork 192.168.1.64

  subnet mask 255.255.255.240

• subnetwork 192.168.1.32

  subnet mask 255.255.255.240

What does the IP address 192.168.1.15/29 represent?

• unicast address

• broadcast address

• subnetwork address

• multicast address

Refer to the exhibit. Which two network addresses can be assigned to the network containing 10 hosts? Your answers should waste the fewest addresses, not reuse addresses that are already assigned, and stay within the 10.18.10.0/24 range of addresses. (Choose two.)

• 10.18.10.224/28

• 10.18.10.208/28

• 10.18.10.224/27

• 10.18.10.200/28

• 10.18.10.240/27

What are two benefits of subnetting networks? (Choose two.)

• decreasing the number of broadcast domains

• increasing the size of collision domains

• grouping devices to improve management and security

• combining multiple smaller networks into larger networks

• reducing the size of broadcast domains

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?

• 4096

• 256

• 65536

• 16

• 60

• 64

The network portion of the address 172.16.30.5/16 is

• 172.16

• 30.5

• 172

• 30
