• B.It allows fast incremental backups to be offloaded to the physical standby database.
• C.It allows fast incremental backups to be taken on the primary database.
• D.It starts the RVWR process on the physical standby database instance.
• E.It starts the CTWR process on the primary database instance.
• F.It starts the CTWR process on the physical standby database instance.

Which two statements are true about Real-Time Query? (Choose two.)

• A.Setting STANDBY_MAX_DATA_DELAY =0 requires synchronous redo transport.
• B.Real-Time Query has no limitations regarding the protection level of the Data Guard environment.
• C.Real-Time Query sessions can be connected to a Far Sync instance.
• D.Disabling Real-Time Query prevents the automatic start of redo apply when a physical standby database is opened READ ONLY.

• A.The LGWR process writes to them on a standby database.
• B.Only standby databases can write redo to them.
• C.They are required only for synchronous redo transport.
• D.They are required on a physical standby for real-time apply.
• E.They are required on a logical standby for real-time apply.
• F.It is recommended to have them on the primary database.

• B.performing role transitions when switchover requests are made
• C.communicating with the DMON process of the observer to monitor a primary database in case a fast start failover is required.
• D.activating role-based services appropriately in the various database instances of the configuration, based on the database role
• E.communicating with DMON processes in other database instances that are part of the broker configuration
