Exam Simulator: IPv4 Addressing

Why does the formula for the number of hosts per subnet (2^H – 2) require the subtraction of two hosts?

Given the following IP addresses, identify which of those are private IP networks? (Choose all that apply.)

You are working with a network designer to build a campus network. He asked you how many subnet (S) bits does he need to create 200 subnets.

Which of the following statements is the correct answer?

Which of the following addresses are not valid Class A network IDs? (Choose all that apply)

What information can you extract having the IP address 172.16.99.45? (Choose two answers.)

Answer the following fill-in-the-blank by typing the range of the Class A private IP networks

Your role is to fill up the table below by typing the first octet range, the valid network numbers and the default mask from Class A, B, and C IP networks.

The addresses in the same network have different values in the network part.

Sort the required steps (from step 1 to step 6) in order to find the:

• Network number

• First (numerically lowest) usable address

• Last (numerically highest) usable address

• Network broadcast address

Your role is to fill up the table below by typing the class network octets, the host octets, the network IDs and the network broadcasts from the following IP addresses.

A network designer asked you how many subnets (S) bits does he need to create 100 subnets? (Type only the number)

Match the IP addresses to their default subnet mask:

The senior network engineer asked you to type the last usable address for a host from the last subnet according to the following details:

Network 9.0.0.0 (Class A)
Mask 255.255.0.0 (for all subnets)

Which of the following addresses are valid Class C network IDs? (Choose two answers)

Answer the following fill-in-the-blank by typing the range of the Class C public IP networks.
