CompTIA Network+ (N10-008) — Question 535

A technician needs to allow a device to maintain the same IP address lease based on the physical address of a network card. Which of the following should the technician use?

Answer options

• A. MAC address reservation
• B. Static IP address
• C. Custom DNS server entry
• D. IP address exclusion

Correct answer: A

Explanation

The correct answer is MAC address reservation, as it allows a specific IP address to be permanently assigned to a device based on its MAC address. A static IP address can also be used, but it does not include the automatic assignment feature based on the MAC address. A custom DNS server entry and IP address exclusion do not relate to maintaining an IP lease based on physical hardware.
