CompTIA Network+ (N10-008) — Question 24

Client devices cannot enter a network, and the network administrator determines the DHCP scope is exhausted. The administrator wants to avoid creating a new
DHCP pool. Which of the following can the administrator perform to resolve the issue?

Answer options

• A. Install load balancers
• B. Install more switches
• C. Decrease the number of VLANs
• D. Reduce the lease time

Correct answer: D

Explanation

Reducing the lease time allows IP addresses to be released and reused more quickly, thereby alleviating the exhaustion of the DHCP scope. The other options do not address the underlying issue of available IP addresses; installing load balancers, switches, or altering VLANs won't resolve the lack of DHCP leases.
