CCNA 1 R&S Introduction to Networks Chapter 9 QUIZ

1 Which two devices do not require an IP address in order to operate on a network? (Choose two.)

hubs*
routers
workstations
switches*
servers

2 Fill in the blank.

Consider the following range of addresses:
2001:0DB8:BC15:0600:0000:: to 2001:0DB8:BC15:0FFF:0000::

The prefix for the range of addresses is “_______”.

Correct Answer
/52

/ 52

3 What does the IP address 192.168.1.15/29 represent?

subnetwork address
multicast address
unicast address
broadcast address*

4 What is an advantage of subnetting a network?

It provides more IP addresses for hosts.
It contains broadcast traffic within its subnet.*
It allows for encapsulation of different types of data packets.
It eliminates the need for the ARP protocol.

5 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 192.168.1.64
subnet mask 255.255.255.192*

subnetwork 192.168.1.32
subnet mask 255.255.255.240

subnetwork 192.168.1.64
subnet mask 255.255.255.240

subnetwork 192.168.1.128
subnet mask 255.255.255.192

subnetwork 192.168.1.8
subnet mask 255.255.255.224

Refer to the exhibit. A company is deploying an IPv6 addressing scheme for its network. The company design document indicates that the subnet portion of the IPv6 addresses is used for the new hierarchical network design, with the site subsection to represent multiple geographical sites of the company, the sub-site section to represent multiple campuses at each site, and the subnet section to indicate each network segment separated by routers. With such a scheme, what is the maximum number of subnets achieved per sub-site?

0
4
16*
256

7 Fill in the blank.

An IPv6 address block with a /48 prefix has a/an “________” bit field for the subnet ID.

Correct Answer
16

sixteen

8 Which two types of device are typically assigned with static IP addresses? (Choose two.)

workstations
web servers*
printers*
hubs
laptops

9 Three devices are on three different subnets. Match the network address and the broadcast address with each subnet where these devices are located. (Not all options are used.)

Device 1: IP address 192.168.10.77/28 on subnet 1

Device 2: IP address192.168.10.17/30 on subnet 2

Device 3: IP address 192.168.10.35/29 on subnet 3

Subnet 1 network number -> 192.168.10.64

Subnet 1 broadcast address -> 192.168.10.79

Subnet 2 network number -> 192.168.10.16

Subnet 2 broadcast address -> 192.168.10.19

Subnet 3 network number -> 192.168.10.32

Subnet 3 broadcast address -> 192.168.10.39

10 A network engineer is subnetting the 10.0.240.0/20 network into smaller subnets. Each new subnet will contain between a minimum of 20 hosts and a maximum of 30 hosts. Which subnet mask will meet these requirements?

255.255.224.0
255.255.240.0
255.255.255.224*
255.255.255.240

11 The network portion of the address 172.16.30.5/16 is “_______”.

Correct Answer
172.16

12 How many host addresses are available on the 192.168.10.128/26 network?

30
32
60
62*
64

13 What is the main reason that a network administrator would use VLSM?

cost savings
enhanced security
efficient use of address space*
shorter delay of data transmissions

14 What two IPv6 prefixes are valid when nibble aligned subnet masks are used (Choose two.)

/64*
/65
/66
/67
/68*
/69
