CompTIA Network+ (N10-009) — Question 3

A network administrator needs to set up a file server to allow user access. The organization uses DHCP to assign IP addresses. Which of the following is the best solution for the administrator to set up?

Answer options

• A. A separate scope for the file server using a /32 subnet
• B. A reservation for the server based on the MAC address
• C. A static IP address within the DHCP IP range
• D. A SLAAC for the server

Correct answer: B

Explanation

The correct answer is B because creating a reservation for the server based on its MAC address ensures it always receives the same IP address from the DHCP server. Option A is incorrect as a /32 subnet does not allow for any other devices to communicate on the same network, and option C, while functional, is less efficient than a reservation. Option D is irrelevant in this context since SLAAC is used for IPv6, not DHCP.
