Introduction to Subnetting

What is Subnetting?

• The process of dividing a network into smaller subnetworks.

• A method to merge networks into a single larger network.

• An error in IP configuration.

• A technique used solely for network security.

Which of the following are benefits of subnetting?

• Improved network performance

• Increased security

• Efficient use of IP addresses

• All of the above

Subnetting is important for network management because...

• It improves network performance and organization.

• It makes the network more expensive.

• It reduces network security.

• It eliminates the need for management.

Subnetting enhances network security by isolating segments and limiting broadcast domains.

• It isolates network segments, restricting broadcast domains.

• It increases the number of available IP addresses.

• It disables firewalls for better accessibility.

• It allows direct connections between all devices.

The benefit of subnetting in terms of IP address efficiency is its ability to _____________________________ the network into smaller segments.

• allows more efficient use of IP addresses by dividing

• increases the total number of available IP addresses in

• completely eliminates IP address wastage

• simplifies the IP assignment process but does not affect efficiency in

For IP 192.168.1.0/24, what is the subnet mask?

• 255.255.255.0

• 255.255.0.0

• 255.0.0.0

• 255.255.255.128

Subnetting divides an IP address into network and host portions using the subnet mask. Which option correctly states the parts determined by the subnet mask?

• Both network and host portions

• Network portion only

• Host portion only

• None of the above

• host

• network

• subnet

• address

How many usable hosts are there per subnet when subnetting 192.168.1.0/24 into 4 subnets?

• The number of usable hosts per subnet when subnetting 192.168.1.0/24 into 4 subnets is 62.

• The number of usable hosts per subnet when subnetting 192.168.1.0/24 into 4 subnets is 64.

• The number of usable hosts per subnet when subnetting 192.168.1.0/24 into 4 subnets is 60.

• The number of usable hosts per subnet when subnetting 192.168.1.0/24 into 4 subnets is 63.

What does CIDR stand for?

• CIDR stands for Classless Inter-Domain Routing.

• CIDR stands for Classful Inter-Domain Routing.

• CIDR stands for Classless Internet Domain Routing.

• CIDR stands for Centralized Inter-Domain Routing.
