A host on a subnet has an IP address of 125.35.88.7 and a subnet mask of 255.255.240.0. What is the broadcast address for the subnet the host belongs to?

A. 125.35.88.255

B. 125.35.94.255

C. 125.35.95.255

D. 125.35.255.255

Solution

C is correct. A Boolean AND between the IP address 125.35.88.7 and the subnet mask of 255.255.240.0 shows the subnet ID as 125.35.80.0. Turning on all the remaining host bits, we have 125.35.01011111.11111111, which equates to 125.35.95.255
