HPE6-A86 · Question #12
New IoT devices cannot obtain an IP address from a DHCP server (10.200.1.51). Based on the output below, what should you configure to resolve the issue?
The correct answer is B. Configure an IP helper for the DHCP server. The IoT clients in VLAN 100 send DHCP requests as broadcasts, which do not cross the Layer 3 boundary to reach a DHCP server in another subnet. Configuring a DHCP relay on interface vlan100 to forward DHCP requests to 10.200.1.51 allows the devices to obtain addresses.
