Which TWO statements are true about database parameters for databases in a Data Guard environment?

• A.The databases that are part of a Data Guard configuration must have different DB_UNIQUE_NAME initialization parameters.
• B.DB_FILE_NAME_CONVERT is only required if the standby database is on the same host as the primary database.
• C.LOG_FILE_NAME_CONVERT applies to online redo logs and archived logs.
• D.COMPATIBLE must have identical values for primary and standby databases.
• E.If DB_RECOVERY_FILE_DEST is specified, then LOG_ARCHIVE_DEST_n is not required for local archive logs.

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 exceeded. Which two would you recommend to avoid this error?

• A.Increase the number of standby redo log files on the primary database.
• B.Reduce I/O latency for the storage used by the primary database.
• C.Increase the size of the buffer cache on the standby database instance.
• D.Increase the network bandwidth between the primary and standby databases.
• E.Change the protection mode to Maximum Protection.
• F.Change the protection mode to Maximum Performance.

Which three statements are true about snapshot standby databases?

• A.A resize command to extend the size of a datafile in the snapshot standby database, which was created in the snapshot standby database, will succeed.
• B.A resize command to reduce the size of an empty datafile in the snapshot standby database, which was created in the snapshot standby database, will succeed.
• C.A resize command to extend the size of a datafile in the snapshot standby database, which was created in the primary database, will succeed.
• D.A resize command to reduce the size of an empty datafile in the snapshot standby database, which was created in the primary database, will succeed.
• E.A resize command to reduce the size of an empty datafile in the snapshot standby database, which was created in the physical standby database, will succeed.

Which three Data Guard monitoring activities may be performed using Enterprise Manager Cloud Control?

• A.You can monitor the redo apply rate on a snapshot standby database.
• B.You can check if redo apply needs to be tuned.
• C.You can monitor the redo apply rate on a logical standby database.
• D.You can set a critical threshold on the redo generation rate metric for a primary database.
• E.You can set a warning threshold on the redo generation rate metric for a physical standby database.
• F.You can check the potential data loss in the event of a disaster.

Your Data Guard environment consists of these components and settings:
A primary database supporting an OLTP workload
A remote physical standby database
Real-time query is enabled
The redo transport mode is set to SYNC
The protection mode is set to Maximum Availability
Which two statements are true regarding the DelayMins database property for the standby database?

• A.It can only be enabled for a configuration in Maximum Availability mode.
• B.It allows user errors on the primary to be recovered by using the physical standby database.
• C.It specifies a delay before the primary ships redo to the standby destination having DelayMins set.
• D.It allows logical corruptions on the primary to be recovered by using the physical standby database.
• E.It enables you to bypass the default network timeout interval specified for the standby redo transport destination.
• F.It can only be enabled for a configuration in Maximum Performance mode.
