World of Computer Networking Your CCNA start - Subnetting Example

The video tutorial explains the need for subnetting and demonstrates how to create subnets from a Class B network. It covers the process of borrowing bits from the host part to form subnets, changing the subnet mask, and calculating the number of hosts per subnet. The tutorial also discusses converting binary to decimal for subnet addresses and introduces advanced subnetting concepts, including calculating broadcast addresses and creating more subnets by borrowing additional bits.

What is the default subnet mask for a Class B network?

• /8

• /16

• /24

• /32

How many subnets can be created by borrowing 2 bits from the host part?

• 8

• 4

• 16

• 2

What is the new subnet mask when 2 bits are borrowed from a /16 network?

• /18

• /20

• /22

• /24

Which of the following is a unique feature of each subnet?

• Same host bits

• Same subnet mask

• Different borrowed bits

• Same network part

What is the decimal equivalent of the binary 01000000 in the context of subnetting?

• 256

• 32

• 64

• 128

How many subnets can be created by borrowing 4 bits?

• 4

• 16

• 8

• 12

What is the maximum number of hosts per subnet when there are 14 host bits?
