Network Administration Quiz 5

What is the purpose of a subnet mask in IP addressing?

• To determine the network portion of an IP address

• To determine the host portion of an IP address

• To determine the class of an IP address

• To determine the country of origin of an IP address

Which standard introduced Classless Inter-Domain Routing (CIDR) to help conserve IPv4 address space?

• RFC 1918

• RFC 1631

• RFC 1519

• RFC 791

What is the advantage of CIDR over classful IP addressing?

• Allows for more efficient use of IPv4 address space

• Increases the number of available IP classes

• Provides faster internet speed

• Enables unlimited host addresses per subnet

Which class of IP addresses range from 128.0.0.0 to 191.255.255.255?

• Class A

• Class B

• Class C

• Class D

What is Variable Length Subnet Masking (VLSM) used for?

• To increase the speed of internet connections

• To determine the class of an IP address

• To subnet a subnet according to individual needs

• To encrypt IP addresses

Which type of routing protocols include subnet masks in their updates?

• Dynamic routing protocols

• Static routing protocols

• Classless routing protocols

• Classful routing protocols

What is the process of subnetting a subnet to fit specific needs called?

• VLSM

• CIDR

• Route summarization

• Supernetting

How is route summarization achieved in CIDR?

• By using static routing protocols

• By encrypting IP addresses

• By increasing the number of available IP classes

• By representing multiple contiguous routes with a single route

Which type of routing updates include subnet masks?

• Classful routing updates

• Classless routing updates

• Static routing updates

• Dynamic routing updates

What is the main benefit of using Classless Inter-Domain Routing (CIDR)?

• More efficient use of IPv4 address space

• Faster internet speed

• Unlimited host addresses per subnet

• Increased security of IP addresses
