QuestionQ20

Implement and manage an on-premises and hybrid networking infrastructure

Your network includes an Active Directory Domain Services (AD DS) domain. The domain has a server named DHCP1 that runs Windows Server with the DHCP Server role installed. DHCP1 uses the static IPv4 address 10.10.10.5/24.

DHCP1 is authorized in AD DS and has an active scope for the 10.10.20.0/24 subnet.

Client computers on the 10.10.20.0/24 subnet receive APIPA addresses. You confirm that the DHCP Server service is running and that the scope has available IP addresses.

You need to ensure that computers on the 10.10.20.0/24 can receive IPv4 address leases from DHCP1.

What should you do?

Explanation

DHCP clients initially send DHCPDISCOVER messages as local broadcasts, which routers normally do not forward between subnets. A DHCP relay agent forwards those messages between the 10.10.20.0/24 client network and DHCP1 on 10.10.10.0/24, allowing DHCP1 to issue leases from the active scope. Microsoft documents that relay agents enable DHCP clients to obtain addresses from a DHCP server on a different subnet.
