Which three are true about using Flashback database through role transitions in a Data Guard environment?

• A.Physical standby databases retain their current role when you flash back to a point in time before the switchover occurred which caused this database to become a physical standby.
• B.Flashback database may not be used to undo a physical standby database activation.
• C.Physical standby databases retain their current role when you flash back to a point in time before a reinstate occurred which caused this database to become a physical standby.
• D.Logical standby database roles are reverted to their original role when you flash back to a point in time before the switchover occurred which caused this database to become a logical standby.
• E.Logical standby databases retain their current role when you flash back through to a point in time before the switchover occurred which caused this database to become a logical standby.

You created two remote physical standby databases using SQL and RMAN.
The primary database is a four-instance RAC database and each physical standby database has two instances.
Roles-based services are used for client connectivity and have been defined in the Grid Infrastructure.
Consider these operational requirements:
* The ability to manage multiple standby databases with a single tool
* The simplification of switchovers, failovers, reinstatements, and conversions to and from snapshot standby databases
* The automation of failovers to a specified target standby database
Which TWO tools can be used to fulfill these requirements7

• A.SQL*Plus
• B.Enterprise Manager Cloud Control
• C.DGMGRL
• D.GDCCTL
• E.RMAN
• F.CRSCTL
• G.SRVCTL

You must configure an Oracle Data..........
1. A primary database
2. A physical standby database
Examine these requirements: 1. Data loss is not permitted.
1. Data loss is not permitted.
2. It should be possible to convert the physical standby database to a snapshot standby database.
3. Under normal operations, transactions should commit when redo is written to disk on the primary database and as soon as it has been received by the standby database instance.
4. The availability of the primary database should not be compromised by the availability of the standby database.
5. It should be possible to convert the physical standby database to a logical standby database
6. It should be possible to deploy Real Application Clusters on the primary database.
7. It should be possible to deploy Real Application Clusters on the physical standby database.
You configure SYNC redo transport mode in combination with Maximum Protection mode.

• A.1, 2, and 5
• B.1, 2, 6, and 7
• C.1, 2, 3, 4, 5, 6, and 7
• D.1, 2, 3, 6, and 7
• E.1, 6, and 7

A Data Guard environment has this configuration and these attributes:
A primary database
A physical standby database named sbdb
The configuration is in maximum availability protection mode.
Then sbdb is converted to a snapshot standby database.
Which two statements are true?

• A.The recovery time objective increases.
• B.sbdb can still apply redo.
• C.The recovery point objective increases.
• D.The protection mode is lowered to maximum performance.
• E.sbdb can still receive redo.

You are licensed to use Oracle Active Data Guard.
Which TWO statements are true after enabling block change tracking on a physical standby database?

• A.It allows fast incremental backups to be offloaded to a snapshot standby database, when the physical standby database is converted.
• B.It starts the CTWR process on the primary database instance.
• C.It starts the CTWR process on the physical standby database instance.
• D.It allows fast incremental backups to be taken on the primary database.
• E.It allows fast incremental backups to be offloaded to the physical standby database.
• F.It starts the RVWR process on the physical standby database instance.
