A workstation is added to a newly created subnet using 192.168.100.0/24. A DHCP server is available on subnet 192.168.101.0/24. The user is unable to lease an address from the DHCP server. Which of…

While assigning a static IP address would allow the workstation to communicate, it bypasses the DHCP issue and is not the "BEST resolve the problem" for enabling DHCP functionality across subnets.

Adding another DHCP server to the same subnet (192.168.101.0/24) does not help the workstation on a different subnet (192.168.100.0/24) receive an address, as broadcasts are still confined.

DHCP Discover broadcasts are limited to the local subnet and cannot cross router boundaries to reach a DHCP server on a different subnet. Adding a DHCP relay agent to the 192.168.100.0/24 subnet would forward the DHCP Discover requests as unicast messages to the DHCP server on 192.168.101.0/24, allowing the workstation to lease an address.

Adding a DHCP server directly to the 192.168.100.0/24 subnet would resolve the issue, but a DHCP relay agent is generally a more efficient and scalable solution for managing DHCP services across multiple subnets from a centralized server, making it a "BEST" solution in many enterprise contexts.
