Which two kinds of failures make the Data Recovery Advisor (DRA) generate a manual checklist?

Which two kinds of failures make the Data Recovery Advisor (DRA) generate a manual checklist?
(Choose two.)

A.
Failure when no standby database is configured

B.
Failure because a data file is renamed accidentally

C.
Failure that requires no archive logs to be applied for recovery

D.
Failure due to loss of connectivity-for example, an unplugged disk cable

Explanation:
Advising on Repair
On the “View and Manage Failures” page, the Data Recovery Advisor generates a manual
checklist after you click the Advise button. Two types of failures can appear.
Failures that require human intervention: An example is a connectivity failure when a disk cable
is not plugged in.
Failures that are repaired faster if you can undo a previous erroneous action: For example, if you

renamed a data file by error, it is faster to rename it back to its previous name than to initiate
RMAN restoration from backup.
You can initiate the following actions:
Click “Re-assess Failures” after you perform a manual repair. Resolved failures are implicitly
closed; any remaining failures are displayed on the “View and Manage Failures” page.
Click “Continue with Advise” to initiate an automated repair. When the Data Recovery Advisor
generates an automated repair option, it generates a script that shows how RMAN plans to repair
the failure. Click Continue if you want to execute the automated repair. If you do not want the Data
Recovery Advisor to automatically repair the failure, you can use this script as a starting point for
your manual repair.
