QUESTION 7
A two-node Solaris Volume Manager campus cluster has been installed at sites A and B. A preferred site A can be configured so that the cluster survives the loss of site B without requiring manual intervention. Which is the correct procedure to create a preferred site A?

A.    Put the quorum device at site A and configure the majority of the diskset metadb replicas on the disks located at site A.
B.    Put the quorum device at site A and add an extra metadb to the disks in the diskset at both sites A and B.
C.    Put the quorum device at site A and add an extra local metadb to the root disk on the server located at site A.
