An IP subnetting design requires 200 subnets and 120 hosts/subnet for the largest subnets, and requires that a single mask be used throughout the one private IP network that will be used. The design also requires planning for 20 percent growth in the number of subnets and number of hosts/subnet in the largest subnet. Which of the following answers lists a private IP network and mask that, if chosen, would meet the requirements?a. 10.0.0.0/25b. 10.0.0.0/22c. 172.16.0.0/23d. 192.168.7.0/24

b. 10.0.0.0/22

Explanation:

Variable length subnet masking is a concept in networking that helps minimize wasting of Ipv4 ( IP version 4) network addressing. It takes a networking address and splits it to variable length.

The question above requires 120 hosts and a future host update of 20%, which is 144 hosts and a subnet of the same address of 200 to 240 in update. The host octet of the network address is totally used, which gives 254 hosts, that is extract 110 hosts. This can be further subnetted.

The two bits from the third octet is used for subnetting to give over 240 subnet mask.

you have to email it to yourself from your phone then download it to either google drive or you computer files. then you can go to where ever you saved it and select it and then copy and paste it. or you could attach it to your question when you are writing it which would be much easier. for example: go to the attachment.

answer would be
