Which three are true concerning restoring of RMAN backups to primary and physical standby databases in a Data Guard environment? (Choose three.)

• A.Backups of data files taken on the primary database may be restored on a physical standby database.
• B.Backups of control files taken on the primary database may not be restored and used on a physical standby database.
• C.Backups of SPFILEs taken on the primary database may not be restored and used on a physical standby database.
• D.Backups of data files taken on a physical standby database may be restored on a primary database.
• E.Backups of SPFILEs taken on a physical standby database may not be restored on the primary database.
• F.Backups of control files taken on a physical standby database may be restored on the primary database.

You must configure an Oracle Data Guard environment consisting of:
1. A primary database
2. One Physical Standby Database
3. One Logical Standby Database
You must meet these requirements:
1. Primary database availability should not be compromised by the availability of the standby databases.
2. Under normal operations, transactions executed on the primary database should not commit before redo is written to disk on both the primary database and at least one standby database.
Which redo transport mode and which protection mode would you configure to meet these requirements?

• A.SYNC NOAFFIRM and Maximum Availability
• B.ASYNC and Maximum Performance
• C.SYNC NOAFFIRM and Maximum Protection
• D.SYNC AFFIRM and Maximum Availability
• E.SYNC AFFIRM and Maximum Protection

You are required to change the Data Guard Configuration protection mode from MAXPERFORMANCE to MAXAVAILABILITY using Enterprise Manager Cloud Control.
Which two are true about this change? (Choose two.)

• A.Real time apply will be automatically turned on.
• B.If the primary database cannot write its redo to at least one synchronized standby database, then the protection level remains unchanged.
• C.The primary database instance will remain up and running, if it cannot write redo to at least one synchronized standby database.
• D.Fast start failover can be enabled when making the chance.
• E.Transactions will not commit until all redo data needed to recover those transactions are written to the online redo log, and to the standby redo log on at least one synchronizes standby database.

Which three are true about using RMAN in a Data Guard environment? (Choose three.)

• A.Backups of archived redo logs taken on a physical standby are interchangeable with a primary.
• B.A recovery catalog is required when RMAN is used to take backups from a physical standby database if you plan to recover the primary using those backups.
• C.Backups of control files taken on a physical standby are not interchangeable with a primary.
• D.A recovery catalog is required when RMAN is used to take backups from a logical standby database in a Data Guard configuration if you plan to recover the primary using those backups.
• E.Backups of data files taken on a physical standby are interchangeable with a primary.

Which three will be true after a switchover to Sheep? (Choose three.)

• A.Sheep will be the primary database.
• B.Dogs will be a disabled logical standby database.
• C.Cats will be a disabled physical standby database.
• D.Dogs will be an enabled logical standby database.
• E.Cats will be an enabled physical standby database.
