DGMGRL > show configuration;

Configuration-Animals -
Protection Mode: MaxAvailability
Databases:
dogs- Primary database
dogsfsl Far Sync
sheep- Physical standby database

Fast-Start Failover: DISABLED -
Configuration Status:

SUCCESS -
An attempt to enable fast-start failover raises an eror:
DGMGRL> enable fast_start failover;
Error: ORA-16693: requirements not met for enabling fast-start failover
Failed.
Identify two possible reasons for this error.

Answer options

• A. The FastStartFailoverTarget property is not set on Sheep.
• B. The FastStartFailoverTarget property is not set on Dogs.
• C. The FastStartFailoverTarget property is not set on DogsFS1.
• D. The LogXptMode property is set to ASYNC on Dogs.
• E. The RedoRoutes property is not set on Dogs.
• F. The RedoRoutes property is not set on DogsFS1.

Correct answer: A, D

Explanation

The error ORA-16693 indicates that the requirements for enabling fast-start failover are not satisfied, and one likely reason is that the FastStartFailoverTarget property must be set for the standby database Sheep (Option A). Additionally, for fast-start failover to function properly, the LogXptMode property should ideally be set to SYNC, and if it's ASYNC on Dogs (Option D), it can also prevent fast-start failover from being enabled.
