Introducing Cisco Data Center Networking (DCICN) — Question 54

Which two options represent a subnet mask that allows for a maximum of 14 available host addresses on a subnet? (Choose two.)

Answer options

• A. 255.255.255.240
• B. 255.255.255.192
• C. 255.255.240.0
• D. 255.255.192.0
• E. /14
• F. /21
• G. /26
• H. /28

Correct answer: A, H

Explanation

The correct answers are A and H. The subnet mask 255.255.255.240 (A) allows for 16 total addresses, minus 2 for network and broadcast, leaving 14 usable addresses. Similarly, /28 (H) also allows for 16 addresses, providing the same number of usable addresses. The other options either allow for more than 14 usable addresses or do not fit the requirement.
