CompTIA Network+ (N10-008) — Question 219

A technician manages a DHCP scope but needs to allocate a portion of the scope’s subnet for statically assigned devices. Which of the following DHCP concepts would be BEST to use to prevent IP address conflicts?

Answer options

• A. Dynamic assignment
• B. Exclusion range
• C. Address reservation
• D. IP helper

Correct answer: B

Explanation

The best option to prevent IP address conflicts when allocating a part of the subnet for static devices is the Exclusion range, as it specifically allows you to reserve a set of IP addresses within the scope that DHCP will not assign. Dynamic assignment would still allow DHCP to assign addresses from the entire scope, while Address reservation is used for specific devices rather than a range. IP helper is unrelated to IP address allocation management.
