Explanation

In active/active HA, both nodes must simultaneously handle traffic while sharing a virtual IP - floating IP (C) and ARP load sharing (D) both support this model. A floating IP is a virtual IP address that can be assigned to either active node, while ARP load sharing allows both nodes to respond to ARP requests for the same virtual IP, distributing traffic across the cluster.

VRRP (A) and HSRP (B) are distractors because both protocols are designed for active/standby (active/passive) redundancy - only one device is actively forwarding at a time, with the other on standby; neither natively supports simultaneous active forwarding across multiple nodes in true active/active fashion.

Memory tip: Think "FA" - Floating IP and ARP load sharing are the two methods that keep both nodes Fully Active. VRRP and HSRP both have "standby" or "redundancy" baked into their names, hinting at their passive-backup nature.
