CompTIA Network+ (N10-008) — Question 401

An IP address is maintained despite a failing UPS that causes a workstation to restart several times. Which of the following would allow this to occur?

Answer options

• A. DHCP reservation
• B. DHCP scope
• C. Name server
• D. Root DNS server

Correct answer: A

Explanation

A DHCP reservation ensures that a specific IP address is always assigned to a particular device based on its MAC address, allowing the IP to remain consistent even during restarts. In contrast, a DHCP scope defines a range of IP addresses available for assignment, but does not guarantee a specific address will remain constant. A Name server and Root DNS server are related to domain name resolution, not IP address assignment.
