Question

Which statement describes one purpose of the subnet mask setting for a host? A) The subnet mask is used to identify the host's unique IP address. B) The subnet mask is used to determine the host's default gateway. C) The subnet mask is used to divide a network into smaller subnetworks. D) The subnet mask is used to encrypt the host's network traffic.

Answer 1

The purpose of the subnet mask setting for a host is to divide a network into smaller subnetworks.

Step-by-step explanation:

The purpose of the subnet mask setting for a host is to C) divide a network into smaller subnetworks.

The subnet mask is a 32-bit number used in conjunction with the host's IP address to determine which part of the IP address represents the network address and which part represents the host address. It helps to identify the network ID and the host ID within that network. By dividing a network into smaller subnetworks, the subnet mask allows for better organization and management of network resources.

For example, if a network has an IP address range of 192.168.0.0 to 192.168.255.255, a subnet mask of 255.255.0.0 would divide the network into multiple subnetworks, each with its range of IP addresses.

Answer 2

The subnet mask for a host is used to divide a network into smaller subnetworks.

Step-by-step explanation:

The purpose of the subnet mask setting for a host is to divide a network into smaller subnetworks.

The subnet mask is a 32-bit value that separates the IP address into network and host portions. It determines which part of the IP address represents the network ID and which part represents the host ID. By using different subnet masks, a network can be divided into smaller subnets, allowing for better organization and management of network resources.

For example, if a network has the IP address 192.168.1.0 and uses a subnet mask of 255.255.255.0, it can be divided into 256 smaller subnets, with each subnet having a range of 254 possible host addresses.
