Check Your Understanding Questions

Complete all the review questions listed here to test your understanding of the topics and concepts in this chapter. Appendix A, “Answers to the ‘Check Your Understanding‛ Questions,” lists the answers.

1. A network design engineer has been asked to design the IPv4 addressing scheme for a customer network. The network will use IPv4 addresses from the 192.168.30.0/24 network. The engineer allocates 254 IPv4 addresses for the hosts on the network but excludes 192.168.30.0/24 and 192.168.30.255/24 IPv4 addresses. Why must the engineer exclude these two IPv4 addresses?

1. The IPv4 address reserved for the default gateway is 192.168.30.0/24 is, and the IPv4 address reserved for the DHCP server is 192.168.30.255/24.
2. IPv4 addresses reserved for the email and DNS servers are 192.168.30.0/24 and 192.168.30.255/24.
3. IPv4 addresses reserved for outside Internet connectivity are 192.168.30.0/24 and 192.168.30.255/24.
4. The network IPv4 address is 192.168.30.0/24, and the IPv4 broadcast address is 192.168.30.255/24.

2. Which of the following are private IPv4 addresses? (Choose three.)

1. 192.168.5.5
2. 10.1.1.1
3. 192.167.10.10
4. 172.32.5.2
5. 172.16.4.4
6. 224.6.6.6

3. Which address prefix range is reserved for IPv4 multicast?

1. 169.254.0.0 to 169.254.255.255
2. 224.0.0.0 to 239.255.255.255
3. 127.0.0.0 to 127.255.255.255
4. 240.0.0.0 to 254.255.255.255

4. Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask?

1. To identify the network address of the destination network
2. To identify the host address of the destination host
3. To identify the broadcast address of the destination network
4. To identify faulty frames

5. What are characteristics of a multicast transmission? (Choose three.)

1. Computers use multicast transmission to request IPv4 addresses.
2. Routers do not forward multicast addresses in the range of 224.0.0.0 to 224.0.0.255.
3. Multicast messages map lower-layer addresses to upper-layer addresses.
4. The source address of a multicast transmission is in the range of 224.0.0.0 to 224.0.0.255.
5. A single packet can be sent to a group of hosts.
6. Multicast transmissions can be used by routers to exchange routing information.

6. When IPv4 is configured for a computer on a network, what does the subnet mask identify?

1. The dynamic subnetwork configuration
2. The pool of addresses assigned within the network
3. The part of the IPv4 address that identifies the network
4. The device that the computer uses to access another network

7. Which network does a host with IPv4 address 172.32.65.13 reside on if it is using a classful, default subnet mask?

1. 172.32.65.32
2. 172.32.65.0
3. 172.32.0.0
4. 172.32.32.0

8. A technician is setting up equipment on a network. Which devices need IP addresses? (Choose three.)

1. A printer with an integrated NIC
2. A PDA that is attached to a network workstation
3. A web camera that is attached directly to a host
4. An IP phone
5. A server with two NICs
6. A wireless mouse

9. Which IP address type is intended for a specific host?

1. Unicast
2. Broadcast
3. Simulcast
4. Multicast

10. What is the equivalent decimal value given a binary number of 11001010?

1. 212
2. 240
3. 202
4. 196

11. How many usable IPv4 hosts are available given a subnet mask of 255.255.255.0?

1. 255
2. 256
3. 252
4. 254

12. What are differences between binary and decimal numbers? (Choose two.)

1. Binary numbers are based on powers of 2.
2. Decimal numbers include 0 through 9.
3. Numbers typed on a keyboard are entered as binary and converted to decimal by the computer.
4. Binary numbers consist of three states: on, off, null. Decimal numbers do not have states.
5. Decimal numbers are based on powers of 1.
