Which service should be disabled on a router to prevent a malicious host from falsely responding to ARP requests with the intent to redirect the Ethernet frames?

• LLDP
• reverse ARP
• proxy ARP
• CDP

Explanation: Proxy ARP is a technique used on a device on a network to answer ARP queries for a device on another network. This service should be disabled on a router and the correct default gateway address should be configured (manually or by DHCP) for the normal process of remote network access. CDP and LLDP are device discovery protocols. Reverse ARP is used to resolve IP addresses.
