Which of the following answers lists the prefix (CIDR) format equivalent of 255.255.254.0?

Type the prefix (CIDR) format equivalent of 255.255.255.240?

Which of the following answers lists the dotted-decimal notation (DDN) equivalent of /30?

Type the dotted-decimal notation (DDN) equivalent of /17.

Your task is to troubleshoot a user’s PC with IP 10.20.30.5 and mask 255.255.255.0. Based on the given details type the number of the network (N), subnet (S), and host (H) bits.

Your task is to troubleshoot a user’s PC with IP 192.168.100.1/28. Based on the given details type the number of the network (N), subnet (S), and host (H) bits.

Which of the following masks, when used within a Class B network, would supply enough subnet bits to support 90 subnets? (Choose two)

Subnet masks can be written as 32-bit binary numbers, but not just any binary number. In particular, the binary subnet mask must follow these rules:

1. The value must not interleave 1s and 0s.

2. If 0s exist, they are on the left.

3. If 1s exist, they are on the right.

Convert the following binary masks to decimal masks.

Convert the following decimal masks to binary masks.

You are working with a network engineer to design a network for the new Campus. He provided the following details:

The IP address is 195.240.37.43
The subnet mask is 255.255.255.224

You have been tasked to:

1) Find the Prefix length
2) Find the Class of the address
3) Find the network (N), subnet (S), and host (H) bits.
4) Calculate the number of subnets in the network, assuming that the same mask is used throughout.
5) Calculate the number of hosts in the subnet.

Type the subnet IDs and the broadcast addresses, from the following IP addresses.

Find the Subnet IDs from the following IP addresses.

Find the broadcast address from the following IP addresses.

Match the IP addresses with their Subnet IDs.

The broadcast address from the IP address 67.68.67.68/12 is 67.79.255.255.

Which of the following answers lists the prefix (CIDR) format equivalent of 255.192.0.0?

Your senior network engineer tells you to configure the DHCP server to lease the last 100 usable IP addresses in subnet 12.5.4.0/23. Which of the following IP addresses could be leased as a result of your new configuration?

Match the dotted-decimal notation (DDN) with the equivalent binary mask
