Drag and Drop Question Refer to the exhibit. Drag and drop the subnet masks from the left onto the corresponding subnets on the right. Not all subnet masks are used. Answer:

The correct answer is 255.255.255.248; 255.255.255.128; 255.255.255.240; 255.255.255.252. Each subnet mask must be chosen based on the number of required hosts in each subnet. The correct masks are selected by finding the smallest power-of-2 block that accommodates the needed hosts plus network and broadcast addresses: /29 (255.255.255.248) supports up to 6 hosts, /25

255.255.255.252

Explanation

Each subnet mask must be chosen based on the number of required hosts in each subnet. The correct masks are selected by finding the smallest power-of-2 block that accommodates the needed hosts plus network and broadcast addresses: /29 (255.255.255.248) supports up to 6 hosts, /25 (255.255.255.128) supports up to 126 hosts, /28 (255.255.255.240) supports up to 14 hosts, and /30 (255.255.255.252) supports up to 2 hosts (point-to-point links). Each mask is matched to the subnet with the host requirement that fits within its usable address range without over-allocating or under-allocating addresses.
