The correct answer is D. Increase the size of the DHCP scope for the network segment in question. When a DHCP scope has exhausted its address pool but additional IP addresses are available in the subnet range, expanding the existing scope is the most direct fix.
Question
A network administrator is installing additional devices on the network. The network segment is currently utilizing all allocated IP addresses. If there are additional addresses available, which of the following would be BEST for the network administrator to perform to accommodate the new network devices?
Options
- ACreate a new DHCP scope for the network segment in question.
- BConfigure the DHCP server for IPv6.
- CConfigure the network to use NAT for the network segment in question.
- DIncrease the size of the DHCP scope for the network segment in question.

Why each option
When a DHCP scope has exhausted its address pool but additional IP addresses are available in the subnet range, expanding the existing scope is the most direct fix.
A new DHCP scope defines an address range for a different subnet or VLAN and does not resolve address exhaustion on the existing network segment.
Configuring IPv6 on the DHCP server is a major architectural change that does not solve IPv4 address exhaustion and requires full client-side IPv6 support.
NAT translates addresses at network boundaries and does not increase the number of leasable addresses available within the local segment.
Increasing the size of the DHCP scope extends the range of IP addresses the server can lease within the existing network segment, immediately resolving address exhaustion without requiring subnet or routing changes. This is the correct approach because additional addresses are explicitly noted as available, making scope expansion a non-disruptive, targeted solution.
