NETWORKING ADDRESSING- WEEK 2

Question 1

What definition best describes “binary”?

Answer 1

A numbering system with a base of 2, using digits 0 and 1.

Question 2

TRUE OR FALSE? Subnetting makes the network more efficient by dividing the network into smaller, interconnected networks which helps to minimize network traffic.

Answer 2

TRUE

Question 3

What is the best definition for Classless Inter-Domain Routing (CIDR) notation?

Answer 3

CIDR is a method that allows an IP address to use any subnet mask, regardless of predefined classes.

Question 4

Which statement represents the binary equivalent of the hexadecimal number AF?

Answer 4

10101111

Question 5

What is an advantage of using hexadecimal over binary?

Answer 5

Hexadecimal notation allows for a more compact representation of binary data.

Question 6

What is a limitation of the IPv4 address space?

Answer 6

The maximum size of an IPv4 address is 32 bits, which limits the number of unique addresses that can be assigned.

Question 7

What best describes Variable Length Subnet Mask (VLSM)?

Answer 7

A method for assigning IP addresses to devices that allow different subnets to have different subnet masks depending on their size.

Question 8

Which statement best describes how IP addresses and subnet masks work together?

Answer 8

An IP address and subnet mask work together to determine the network and host portions of an IP address.

Question 9

Complete the sentence. An IPv4 address consists of ___________.

Answer 9

32 bits divided into four octets.

Question 10

How many bits would the network portion need to “borrow” from the host portion in order to create 16 new sub-networks?

Answer 10

4 host bits

Question 11

What are the key characteristics of the IPv6 protocol?

Answer 11

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

Question 12

What is the structure and format of MAC addresses?

Answer 12

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

Question 13

TRUE OR FALSE? The IPs 192.168.2.3/24 and 192.61.123.1/24 are in the same subnet.

Answer 13

FALSE

Question 14

How do IP addresses and subnet masks work?

Answer 14

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 15

What is the structure of IPv6 addresses?

Answer 15

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

Question 16

TRUE OR FALSE? IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses.

Answer 16

TRUE

Question 17

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

Answer 17

They provide a unique identifier for devices on a network.

Question 18

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

Answer 18

TRUE

Question 19

What is not a reason for subnetting a large network?

Answer 19

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

Question 20

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

Answer 20

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