CompTIA Network+ (N10-007) — Question 236

An end-user device requires a specific IP address every time it connects to the corporate network; however, corporate policy does not allow the use of static IP addresses. Which of the following will allow the request to be fulfilled without breaking the corporate policy?

Answer options

• A. DHCP relay
• B. DHCP exclusion
• C. DHCP option
• D. DHCP reservation

Correct answer: D

Explanation

DHCP reservation allows a specific IP address to be assigned to a device based on its MAC address, ensuring the device receives the same IP each time it connects without breaching the static IP policy. The other options do not provide a mechanism for consistently assigning the same IP address to a device; for instance, DHCP relay and option do not focus on IP address consistency, and DHCP exclusion is meant for preventing specific IPs from being assigned.
