Question

A network administrator is installing additional devices on the network. Currently, the network segment is 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 an existing network segment has exhausted its allocated IP addresses, expanding the existing DHCP scope is the most direct way to make more addresses available on that segment.

ACreate a new DHCP scope for the network segment in question.

Creating a new DHCP scope generates a separate address pool for a different subnet; devices on the original segment would not automatically receive addresses from a new, unrelated scope.

BConfigure the DHCP server for IPv6.

Configuring the DHCP server for IPv6 is a significant architectural change and does not resolve the immediate IPv4 address exhaustion on the existing segment without reconfiguring all devices.

CConfigure the network to use NAT for the network segment in question.

NAT translates addresses between network boundaries but does not increase the number of available IP addresses within the existing internal network segment.

DIncrease the size of the DHCP scope for the network segment in question.Correct

Increasing the size of the existing DHCP scope extends the range of IP addresses the DHCP server can assign within the current network segment, immediately accommodating new devices without restructuring the network or changing client configurations. This is the least disruptive and most targeted solution when additional addresses are available in the subnet.
