Explanation

Before upgrading a VCD appliance cluster, you must protect the entire cluster (not just one node) with a snapshot so you can roll back every appliance if the upgrade fails - making A correct and B/C wrong because snapshots of only the primary or only the standby leave the rest of the cluster unprotected. You must also switch database failover from Manual to Automatic (option D) so that the embedded PostgreSQL database can promote a standby node on its own if the primary becomes unavailable during the rolling upgrade sequence - option E is the exact opposite and would leave you requiring manual intervention at the worst possible moment.

Memory tip: Think "ALL nodes, AUTO failover" - before the upgrade, go big (whole cluster) and go hands-free (automatic), so the upgrade can proceed without gaps in protection or availability.
