Which three operations are available for a quarterly maintenance update on Autonomous Container Database?

Oracle Autonomous Container Database (ACD) provides specific options for managing quarterly maintenance updates to ensure minimal disruption and flexibility. The three correct operations available are:

Reschedule and patch immediately (B):This option allows users to adjust the maintenance window to a more convenient time and apply the patch right away within that rescheduled window. It’s useful when the default schedule conflicts with business operations but immediate patching is still desired.

Reschedule patching (C):This option enables users to defer the patching to a later maintenance window that suits their operational needs, providing flexibility without applying the patch immediately.

Skip patching (D):Users can choose to skip a quarterly maintenance update entirely, which is beneficial if the current database version is stable and no immediate updates are required. Oracle allows skipping up to two consecutive quarterly updates for Autonomous Container Databases on dedicated infrastructure.

The incorrect options are:

Patch immediately (A):This is not a standalone option for quarterly updates on ACDs. Patching occurs within scheduled maintenance windows, and immediate patching outside of rescheduling is not supported as a distinct choice.

Apply a partial patch (E):Oracle does not support applying partial patches during quarterly maintenance updates. Updates are delivered as complete bundles to ensure consistency and security.

This aligns with Oracle’s maintenance policies for Autonomous Databases on dedicated infrastructure, where control over scheduling and skipping is provided, but partial patching is not an option.
