CompTIA Network+ (N10-007) — Question 163

Which of the following would allow a device to maintain the same IP address lease based on the physical address of the network card?

Answer options

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

Correct answer: A

Explanation

The correct answer is A, MAC address reservation, as it specifically binds an IP address to a device's MAC address, ensuring that the device always receives the same IP lease. Options B and C do not provide this functionality; a static IP is manually assigned, while an exclusion prevents an IP from being assigned by DHCP. Option D is unrelated, focusing instead on DNS settings.
