Question 1 of 10

Which of the following are not valid Class A network IDs? (Choose two answers.)

127.0.0.0

1.0.0.0

130.0.0.0

9.0.0.0

Question 2 of 10

Which of the following statements are true regarding the binary subnet ID, subnet broadcast address, and host IP address values in any single subnet? (Choose two answers.)

The host part of the subnet ID is all binary 0s.

The host part of a usable IP address can have all binary 1s.

The host part of the broadcast address is all binary 0s.

The host part of any usable IP address must not be all binary 0s.

Question 3 of 10

A Class B network needs to be subnetted such that it supports 100 subnets and 100 hosts/subnet. Which of the following answers list a workable combination for the number of network, subnet, and host bits? (Choose two answers.)

Network = 16, subnet = 9, host = 7

Network = 8, subnet = 7, host = 17

Network = 16, subnet = 8, host = 8

Network = 16, subnet = 7, host = 7

Question 4 of 10

Which of the following is a classful network broadcast address?

192.168.255.1

172.30.255.255

10.1.255.255

224.1.1.255

Question 5 of 10

Which of the following are true about IP address 192.168.6.7’s IP network? (Choose two answers.)

The network ID is 192.168.6.0.

The default mask for the network is 255.255.255.0.

The number of host bits in the unsubnetted network is 16.

The network is a Class B network.

Question 6 of 10

Which of the following statements is true about classless IP addressing concepts?

Separates IP addresses into network, subnet, and host parts

Ignores Class A, B, and C network rules

Uses a 128-bit IP address

Applies only for Class A and B networks

Question 7 of 10

Which of the following masks, when used as the only mask within a Class B network, would supply enough subnet bits to support 100 subnets? (Choose two.)

/20

255.255.252.0

/24

255.255.255.252

Question 8 of 10

Which of the following answers lists the dotted-decimal notation (DDN) equivalent of /30?

255.255.255.0

255.255.255.240

255.255.255.192

255.255.254.0

Question 9 of 10

Working at the help desk, you receive a call and learn a user’s PC IP address and mask (10.55.66.77, mask 255.255.255.0). When thinking about this using classful logic, you determine the number of network (N), subnet (S), and host (H) bits. Which of the following is true in this case?

N=24

N=12

S=12

H=8

S=8

172.31.201.255

172.31.77.207

172.31.77.223
