Multiple choice

What is the purpose of a subnet mask?

  1. To divide a network into smaller subnetworks

  2. To determine the network address of a host

  3. To determine the broadcast address of a network

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A subnet mask serves multiple purposes. It is used to divide a network into smaller subnetworks, allowing for more efficient routing and addressing. It also helps determine the network address of a host, which is the first address in the subnet, and the broadcast address, which is the last address in the subnet.

Multiple choice

What is the maximum number of subnetworks that can be created from a network with a subnet mask of 255.255.255.192?

  1. 2

  2. 4

  3. 8

  4. 16
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The number of subnetworks that can be created from a network is determined by the number of bits in the host portion of the subnet mask. In this case, the host portion is 8 bits (32 - 24 = 8), so the maximum number of subnetworks is 2^8 = 256. However, since the network address and broadcast address also occupy two addresses, the actual number of usable subnetworks is 256 - 2 = 254.
