CompTIA Network+ (N10-008) — Question 605

A network administrator is configuring DCHP and wants to explicitly set an IP address based on a MAC address. Which of the following should the administrator use?

Answer options

• A. Dynamic assignment
• B. Static IP on the server
• C. IP helper
• D. Exclusion range
• E. Reservation

Correct answer: E

Explanation

The correct answer is E, Reservation, which allows the administrator to allocate a specific IP address to a device based on its MAC address. The other options are not suitable for this purpose: Dynamic assignment provides IPs from a pool without MAC binding, Static IP on the server is not managed by DHCP, IP helper is for forwarding DHCP requests, and Exclusion range is used to reserve IPs from being assigned dynamically.
