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
Data Recovery Advisor can generate a manual checklist.
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 required faster if you can undo a previous erroneous action: for example, if you renamed a data file by error, it’s faster to rename it back to its previous name than initiate RMAN restoration from backup.

In some cases, the only possible actions are manual.
