Suggested Answer: A 🗳️
As with standard upgrades to Oracle Grid Infrastructure, at any given point in time for normal operation of the cluster, all the nodes in the cluster must have the same software release and patch level. Because one-off patches can be applied as rolling upgrades, all possible patch levels on a particular software release are compatible with each other.
Note: Starting with Oracle Grid Infrastructure 12c Release 1 (12.1), a new cluster state called "Rolling Patch" is available. This mode is similar to the existing
"Rolling Upgrade" mode in terms of the Oracle ASM operations allowed in this quiesce state.
