Your company requires two diverse multihop eBGP peerings to a partner network. Which two methods should you use to improve lost peer detection? (Choose 2)

Fast Peering Session Deactivation immediately tears down a BGP session when the interface used to reach the peer goes down, bypassing the hold-timer countdown and providing near-instantaneous lost-peer detection for multihop sessions.

Sub-second BGP keepalives are not recommended because they generate excessive CPU load on both peers and can cause session instability under congestion or packet loss, making them an unreliable detection mechanism.

Sub-second hold timers risk excessive BGP session flapping from normal transient packet loss; BGP standards specify a minimum hold time of 3 seconds, and reducing this further creates operational instability.

The minimum route advertisement interval (MRAI) governs how frequently BGP sends UPDATE messages, which affects convergence speed but has no effect on how quickly a lost BGP peer session is detected.

Selective Address Tracking monitors the routing table for the reachability of the BGP peer's IP address; when the peer route is withdrawn or disappears, the BGP session is immediately deactivated, making it well-suited for multihop eBGP topologies where no direct interface link exists.
