Client PCs Unable to Receive Addressing Information

Client PCs are unable to receive addressing information from a newly configured interface on a router.

Which of the following should be added to allow the clients to connect?

A.

DHCP lease time

B.

IP helper

C.

TTL

D.

DNS record type.

B.

When a client PC is unable to receive addressing information from a newly configured interface on a router, it means that the router is not forwarding the DHCP broadcast messages to the DHCP server. To allow the clients to connect, the router needs to be configured with an IP helper.

Option A, DHCP lease time, is not relevant in this scenario. DHCP lease time determines how long an IP address will be assigned to a client.

Option C, TTL (Time To Live), is a field in the IP header that specifies how many hops a packet can take before being discarded. It is not relevant to this scenario.

Option D, DNS record type, is also not relevant in this scenario. DNS record type determines the type of DNS record being queried or created, such as A, AAAA, MX, CNAME, etc.

Option B, IP helper, is the correct answer. An IP helper is a feature that is configured on a router to forward DHCP broadcast messages to a DHCP server on another network. The IP helper allows DHCP clients to obtain IP addressing information from a DHCP server located on a different subnet or network segment.

In summary, when clients are unable to receive addressing information from a newly configured interface on a router, configuring an IP helper on the router will allow DHCP broadcast messages to be forwarded to the DHCP server, and clients will be able to obtain IP addressing information.
