Nokia Certified Network Associate (NCNA) — Question 11

A network with address 208.40.224.0/24 is divided into /28 subnets. What is the network address of the third subnet?

Answer options

• A. 208.40.224.16/28
• B. 208.40.224.32/28
• C. 208.40.224.48/28
• D. 208.40.224.64/28

Correct answer: C

Explanation

When dividing the /24 network into /28 subnets, each subnet has 16 addresses (14 usable). The first subnet is 208.40.224.0/28, the second is 208.40.224.16/28, and the third is 208.40.224.32/28. Therefore, the third subnet's network address is 208.40.224.48/28, making option C the correct answer.
