What is exchanged through the HA2 link?
Explanation
Correct: C
"Data Link—The HA2 link is used to synchronize sessions, forwarding tables, IPSec security associations and ARP tables between devices in an HA pair. Data flow on the HA2 link is always unidirectional (except for the HA2 keep-alive); it flows from the active device to the passive device."
