Nokia Certified Network Associate (NCNA) — Question 22

Given the associated prefix value, which of the following is a valid host address?

Answer options

• A. 172.16.224.255/18
• B. 255.255.255.255/32
• C. 224.1.2.1/8
• D. 192.168.24.59/30

Correct answer: A

Explanation

Option A, 172.16.224.255/18, is a valid host address as it falls within the defined range for that subnet. Option B is a broadcast address for the entire subnet and cannot be assigned to a single host. Option C is an address that falls within the multicast range and is not valid for a host. Option D, while a valid address, is at the end of its subnet range, making it unsuitable as a host address.
