Question 1 of 10

Host A is a PC, connected to switch SW1 and assigned to VLAN 1. Which of the following are typically assigned an IP address in the same subnet as host A? (Choose two answers.)

All other hosts attached to the same switch

The local router’s WAN interface

The local router’s LAN interface

Other hosts attached to the same switch and also in VLAN 1

Question 2 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=12

H=8

S=12

N=24

S=8

Question 3 of 10

Which of the following is the subnet broadcast address for the subnet in which IP address 172.31.77.201/27 resides?

172.31.201.255

172.31.77.223

172.31.255.255

172.31.77.207

Question 4 of 10

Why does the formula for the number of hosts per subnet (2H – 2) require the subtraction of two hosts?

To reserve addresses for the subnet broadcast address and subnet ID

To reserve the two addresses required for DHCP operation

To reserve two addresses for redundant default gateways (routers)

To reserve addresses for the subnet ID and default gateway (router)

Question 5 of 10

A fellow engineer tells you to configure the DHCP server to lease the last 100 usable IP addresses in subnet 10.1.4.0/23. Which of the following IP addresses could be leased as a result of your new configuration?

10.1.7.200

10.1.255.200

10.1.4.254

10.1.5.200

10.1.4.156

Question 6 of 10

Working at the help desk, you receive a call and learn a user’s PC IP address and mask (192.168.9.1/27). 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

S=24

H=8

H=7

Question 7 of 10

Which of the following answers lists the prefix (CIDR) format equivalent of 255.255.255.240?

/26

/30

/29

/27

/28

Question 8 of 10

A network engineer spends time thinking about the entire Class B network 172.16.0.0, and how to subnet that network. He then chooses how to subnet this Class B network and creates an addressing and subnetting plan, on paper, showing his choices. If you compare his thoughts about this network before subnetting the network, to his thoughts about this network after mentally subnetting the network, which of the following occurred to the parts of the structure of addresses in this network?

The network part got smaller.

The subnet part got smaller.

The network part was removed.

The host part was removed.

The host part got smaller.

Question 9 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.)

255.255.255.252

/20

255.255.252.0

/24

Question 10 of 10

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

Separates IP addresses into network, subnet, and host parts

Uses a 128-bit IP address

Ignores Class A, B, and C network rules

Applies only for Class A and B networks
