You must design an Oracle Data Guard configuration for an OLTP database that meets these permanent requirements:
1. Data loss is not permitted.
2. Read-only applications should not connect to the primary database instance.
Additionally, there are these requirements, only one of which is ever done at any one time:
1. It should be possible to apply designated patches with a minimum amount of downtime.
2. Upgrading to a new database release should be performed with the least possible amount of downtime.
3. New application software releases should be tested against an exact and up-to-date replica of the primary database.
Which configuration meets these requirements with the fewest databases?
Which three are prerequisites for enabling Fast-Start Failover?
Which two are true about the creation of a Data Guard Broker configuration?

Which two are true about the output of this DGMGRL command?
Which two Data Guard features require the use of flashback database by the broker?

Your Data Guard environment consists of these components and settings:
1. A primary database
2. A remote physical standby database
3. Real-time query is enabled
4. The redo transport mode is set to SYNC.
5. The protection mode is set to Maximum Availability.
You notice that queries executed on the physical standby database receive errors: ORA- 03172: STANDBY_MAX_DATA_DELAY of 15 seconds exceede
Examine the Data Guard configuration:
Identify two possible reasons for this error.
