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?
A.
cluster-2 is declared the winner after 5 seconds and I/O will continue at that cluster.
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.
