CompTIA Network+ (N10-008) — Question 550

A network administrator creates a new network, 10.10.0.0/24, on a DHCP server. The administrator wants to ensure that 10.10.0.10-10.10.0.15 are not allocated to other devices. Which of the following features should the administrator configure?

Answer options

• A. Exclusion
• B. Reservation
• C. Scope
• D. Relay

Correct answer: A

Explanation

The correct answer is A, Exclusion, which allows specific IP addresses within a DHCP scope to be excluded from being assigned to clients. Option B, Reservation, is about permanently assigning specific IPs to devices, while C, Scope, defines the range of IPs available for allocation. Option D, Relay, is used for forwarding DHCP requests across different subnets, not for excluding IPs.
