What is the expected behavior of the virtual volumes in the event of a WAN-COM failure?

You created a synchronous consistency group, which contains two distributed volumes configured with the rule "set cluster-1-detaches".

What is the expected behavior of the virtual volumes in the event of a WAN-COM failure?

B . I/O will continue at both clusters.
C . I/O will be suspended at both clusters until the WAN-COM is repaired.
D . cluster-1 is declared the winner after 5 seconds and I/O will continue at that cluster.

Answer: A
