Back 2

To reserve addresses for the subnet broadcast address and subnet ID

D. 192.1.168.0

E. 1.0.0.0

Back 5

9.0.0.0

192.1.168.0

1.0.0.0

Front 6

Before Class B network 172.16.0.0 is subnetted by a network engineer, what parts of the structure of the IP addresses in this network already exist, with a specific size? (Select two answers.)

Back 6

Network

Host

Front 7

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 andcreates 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 theparts of the structure of addresses in this network?

Back 7

The host part got smaller.

Front 8

Which of the following terms are not used to reference the one number in each subnet used to uniquely identify the subnet? (Select two answers.)

Back 8

Subnet broadcast

Subnet name

Front 9

An IP subnet is a subset of a Class A, B, or C network. The word subnet is a shortened version of the phrase _____.

Back 9

subdivided network

Front 10

IP addressing rules group addresses into groups called subnets. The rules are as follows:

Back 10

Addresses in the same subnet are not separated by a router.

Addresses in different subnets are separated by at least one router.

Front 11

The decision of how to subnet a network lies with the answer to the following:

Back 11

The number of subnets required (how many networks do I need?)

The number of hosts needed in each subnet

Front 12

Devices receive their IP address and mask assignments in one of two ways:

Back 12

dynamic, by using DHCP

static

Front 13

Addresses in the classful network have a structure with two parts:

Back 13

The network part (some- times called the prefix)

The host part.

Front 14

Each classful network has four key numbers that describe the network. You can drive these four numbers if you start with just one IP address in the network. The numbers are as follows:

Back 14

Network number

First (numerically lowest) usable address

Last (numerically highest) usable address

Network broadcast address

Front 15

Which of the following are true about IP address 172.16.99.45’s IP network? (Select two answers.)

Back 15

The network is a Class B network.

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

Front 16

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

Back 16

The network ID is 192.168.6.0.

The default mask for the network is 255.255.255.0.

Front 17

Which of the following is a network broadcast address?

Back 17

172.30.255.255

Front 18

Which of the following is a Class C network ID?

Back 18

192.168.1.0

Front 19

Which of the following answers lists the prefix (CIDR) format equivalent of 255.255.254.0?

Back 19

/23

Front 20

Which of the following answers lists the prefix (CIDR) format equivalent of255.255.255.240?

Back 20

/28

Front 21

Which of the following answers lists the dotted-decimal notation (DDN) equivalent of /24?

Back 21

255.255.255.0

Front 22

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

Back 22

255.255.255.252

Front 23

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?

Back 23

H=8

Front 24

An engineer is thinking about the following IP address and mask using classless IP addressing logic: 10.55.66.77, 255.255.255.0. Which of the following statements are true when using classless addressing logic? (Choose two.)

Back 24

The prefix length is 24 bits.

The host part’s size is 8 bits.

Front 25

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