HPE Aruba Certified Central Associate (ACCA) — Question 49

Which statement is true given the IP address 10.64.0.240 and subnet mask 255.255.254.0?

Answer options

• A. 10.64.0.240 is a broadcast address.
• B. There are more than 8 bits in the host portion.
• C. The network portion of the address is 10.64.
• D. The prefix length of the network is /25.

Correct answer: B

Explanation

The correct answer is B because the subnet mask 255.255.254.0 indicates that 23 bits are allocated for the network portion, leaving 9 bits for the host portion. Option A is incorrect as 10.64.0.240 is not a broadcast address but a usable IP address. Option C is wrong because the network portion is actually 10.64.0.0. Option D is incorrect since the prefix length for this subnet mask is /23, not /25.
