Exam MTCNA Topic 2 Question 48 Discussion

Proxy ARP allows a router to answer ARP requests on behalf of another device. It is often used in networks where hosts don't have proper default gateways but still need to communicate with devices in different subnets.
MTCNA Course Material - ARP Types:
"Proxy ARP allows a router to respond to an ARP request for an IP address that is not on the local subnet, effectively acting as a proxy." Rene Meneses MTCNA Guide - ARP Configuration:
"Proxy ARP is useful for bridging two IP networks or for clients that do not have default gateways defined." MikroTik Wiki - ARP Modes:
"When Proxy ARP is enabled, the router replies to ARP requests for hosts that are not on the same subnet." Other options:
* A: Gateway DP is not a standard term or protocol.
* B: RARP maps MAC to IP - outdated and not used in this context.
* D: Inverse ARP is used in Frame Relay, not Ethernet/IP networks.
