Test your Knowledge: Subnetting and CIDR

1. What is the primary purpose of subnetting?

A) To increase the total number of available IP addresses
B) To improve network performance and security by dividing a larger network into smaller sub-networks
C) To change the IP address range of a network
D) To eliminate the need for a subnet mask

2. In CIDR notation, what does the number after the slash (/) represent?

A) The number of available IP addresses in the network
B) The total length of the IP address
C) The number of bits used for the network prefix
D) The number of subnets

True or False: Subnetting can help reduce network congestion by decreasing the size of broadcast domains.

True
False

True or False: CIDR allows for more flexible IP address allocation compared to traditional classful networking.

True
False

Fill in the blank: The IP address 192.168.1.0 with a subnet mask of 255.255.255.192 can be represented in CIDR notation as .

Check

Match the CIDR notation with the correct subnet mask:

1. /24
2. /26
3. /28

5. /16

a) 255.255.255.252
b) 255.255.255.0
c) 255.255.255.192
d) 255.255.255.240
e) 255.255.0.0
