• Question 71:

  Which statement is FALSE about Autonomous Database Maintenance on dedicated Exadata infrastructure?

  A. If a scheduled container database maintenance run cannot take place, Oracle will automatically reschedule thecontainer database maintenance for the following quarter.

  B. Autonomous Exadata Infrastructure maintenance takes place at least once each quarter and is

  mandatory.

  C. You can change your container database maintenance window or reschedule a single container database maintenance run to ensure that your container database maintenance runs follow infrastructure maintenance within the same quarter.

  D. Autonomous Exadata Infrastructure maintenance runs are for infrastructure patching (including patching of theExadata grid infrastructure code and operating systems updates), and include database patching.

  Correct Answer: D

  Exadata infrastructure maintenance takes place at least once each quarter and is mandatory.

  If a scheduled container database maintenance run cannottake place (because of changes made to infrastructure maintenance scheduling or other reasons) , Oracle will automatically reschedule the container database maintenance for the following quarter.

  You can change your container database maintenance window or reschedule a single container database maintenance run to ensure that your container database maintenance runs follow infrastructure maintenance within the same quarter. Exadata infrastructure maintenance patches the Exadata infrastructure (including patching of the Exadata grid infrastructure code and operating systems updates), and DO NOT include database patching.

• Question 72:

  While creating an Autonomous Container Database on dedicated infrastructure through the Oracle Cloud Infrastructure(OCI) console, which patch type is offered to be applied during maintenance?

  A. Release Update (RU)

  B. Prior Release Update Revision (PRUR)

  C. Prior Release Update (PRU)

  D. Quarterly Bundle Patch (QBP)

  Correct Answer: A
