Controllers fails over?

Answer options

• A. Gratuitous ARP
• B. Reverse ARP
• C. Proxy ARP
• D. HSRP
• E. BOOTP

Correct answer: B

Explanation

Reverse ARP (Address Resolution Protocol) is utilized for enabling devices to obtain their IP address from a known MAC address, particularly during a failover situation. The other options, such as Gratuitous ARP and Proxy ARP, serve different purposes like updating ARP tables or enabling communication between different subnets, respectively, and are not specifically designed for handling failovers.
