A TCP transfer survives failover, but a UDP stream does not. Ordinary session-pickup is enabled and the topology has converged. Which additional configuration is relevant?

Choose the single best answer.

A.Enable configuration synchronization without copying connectionless state
B.Increase device priority to preserve the UDP session
C.Enable session-pickup-delay to guarantee every short-lived UDP session is copied
D.Enable the supported connectionless session-pickup setting

Show the answer and explanation

✓ Correct answer

Enable the supported connectionless session-pickup setting

The additional connectionless setting synchronizes eligible UDP/ICMP state. Configuration or priority does not copy it; delayed synchronization can leave recent state uncopied rather than guaranteeing preservation.
