CompTIA Network+ (N10-007) — Question 612

Which of the following is used to define the duration during which a client can use an IP address?

Answer options

• A. MAC reservation
• B. IP helper
• C. Pool
• D. Lease time

Correct answer: D

Explanation

The correct answer is 'Lease time' as it directly refers to the duration an IP address is assigned to a client. Options like 'MAC reservation' and 'IP helper' are related to DHCP but do not define time duration, while 'Pool' refers to a collection of IP addresses rather than the time they can be used.
