Chapter 8 Networking 1

What is a result of connecting two or more switches together?

• The number of broadcast domains is increased

• The size of the broadcast domain is increased

• The number of collision domains is reduced

• The size of the collision domain is increased

Refer to the exhibit. How many broadcast domains are there?

• 1

• 2

• 3

• 4

What are two reasons a network administrator might want to create subnets? (Two Options)

• Simplifies network design

• Improves network performance

• easier to implement security polocies

• reduction in number of routers needed

• reduction in number of switches needed

Refer to the exhibit. A company uses the address block of 128.107.0.0/16 for its network. What subnet mask would provide the maximum number of equal size subnets while providing enough host addresses for each subnet in the exhibit?

• 255.255.255.0

• 255.255.255.128

• 255.255.255.192

• 255.255.255.224

• 255.255.255.240

If a network device has a mask of /28, how many IP addresses are available for hosts on this network?

• 256

• 254

• 62

Which subnet mask would be used if 5 host bits are available?

• 255.255.255.0

• 255.255.255.128

• 255.255.255.224

• 255.255.255.240

A network administrator is variably subnetting a network. The smallest subnet has a mask of 255.255.255.248. How many usable host addresses will this subnet provide?

• 4

• 6

• 8

• 10

• 12
