The failover service group named websg is FROZEN and is ONLINE/PARTIAL in a two- node cluster. The

power is unplugged from the system on which websg is ONLINE/PARTIAL.

Consider the configuration file below:

group wewbsg (

AutoFailover = 1

AutoStartList = { sym1, sym2 }

Parallel = 0)

What will be the state of websg on the surviving system?

A. AutoDisabled

B. OFFLINE

C. FROZEN

D. ONLINE/PARTIAL
