CompTIA Network+ (N10-009) — Question 521

A technician configures a new printer and places it on the network. Which of the following is the best way to ensure the printer will always keep the same IP configuration?

Answer options

• A. Add a new scope.
• B. Place an exclusion.
• C. Extend the lease time.
• D. Create a reservation.

Correct answer: D

Explanation

Creating a reservation is the best method to ensure that the printer retains the same IP configuration because it assigns a specific IP address to the printer's MAC address. The other options do not guarantee a fixed IP; adding a new scope increases address availability, placing an exclusion only prevents certain addresses from being assigned, and extending the lease time simply prolongs the duration an IP can be used before renewal.
