Computer Networking Fundamentals Week 2

Question 1

CIDR is used to further subnet, while VLSM is only concerned with preserving IP addresses.

Answer 1

False

False. VLSM is used to create smaller subnets within a larger network.

Question 2

IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses.

Answer 2

True.

True. IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses.

Question 3

What is the structure and format of MAC addresses?

Answer 3

MAC addresses are 48-bit numbers typically represented by 12 hexadecimal characters.

MAC addresses are 48-bit numbers typically represented by 12 hexadecimal characters.

Question 4

The IPs 192.168.2.3/24 and 192.61.123.1/24 are in the same subnet.

Answer 4

False

Question 5

How do IP addresses and subnet masks work?

Answer 5

An IP address is used to identify a device on a network, while a subnet mask is used to determine the network portion of the address.

Question 6

What are the key characteristics of the IPv6 protocol?

Answer 6

IPv6 addresses are 128 bits long and are represented in hexadecimal notation.

Question 7

What is the purpose and function of MAC addresses in computer networking?

Answer 7

They provide a unique identifier for devices on a network.

Question 8

What is the structure of IPv6 addresses?

Answer 8

IPv6 addresses consist of eight groups of four hexadecimal digits separated by colons.

Question 9

With CIDR notation, IP addresses are allowed to use any subnet mask, regardless of predefined classes.

Answer 9

True

Question 10

What is not a reason for subnetting a large network?

Answer 10

Subnetting increases the size of the network and network traffic, allowing more packets to be delivered.
