Which three types of backups taken in which situations may be used to perform restore operations to a logical standby database in a Data Guard environment? (Choose three.)

• A.backups of data files taken on the primary database if connected to the recovery catalog where the logical standby database is registered
• B.backups of data files taken on the standby database if connected to the recovery catalog where the logical standby database is registered
• C.backups of control files taken on the primary database if connected to the recovery catalog where the logical standby database is registered
• D.backups of data files taken on the logical standby database, if not connected to a recovery catalog
• E.backups of control files taken on the logical standby database if not connected to a recovery catalog

Your expertise is requested for these customer requirements:
1. The Data Guard environment must be in maximum protection mode. 2 Reports must be offloaded to a physical standby database.
3. There must be no lag between the primary and standby databases that affect the reports produced.
4. The primary database must be resilient in case of a single network failure.
Which solution is correct for these requirements?

• A.two physical standby databases with Real-Time Query enabled, receiving redo from the primary with the LOG_ARCHIVE_DEST_n attnbutes SYNC NOAFFIRM to minimize the performance impact on the primary.
• B.two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DELAY parameter set to zero, receiving redo from the primary with asynchronous transport
• C.one physical standby database with Real-Time Query enabled and the
  STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport
• D.one physical standby database with Real-Time Query enabled, receiving redo from two
  Far Sync instances that are connected the primary
• E.two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport

Your Data Guard environment consists of these components and settings:
1. A primary database supporting an OLTP workload
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.
Which two are true regarding the DelayMins Database Property for the standby database?

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

Which two are true about database roles in an Oracle Data Guard Configuration?

• A.A configuration consisting only of a primary and one or more physical standby databases can support a rolling release upgrade.
• B.A Logical Standby Database can be converted to a Snapshot Standby Database.
• C.A Logical Standby Database can cascade redo to a terminal destination.
• D.A Snapshot Standby Database can be a fast-start failover target.
• E.A Physical Standby Database can be converted into a Logical Standby Database.

Examine the Data Guard configuration:
DGMGRL> show configuration;
Configuration -Animals
Protection Mode: MaxPerformance
Databases:
dogs- Primary database
sheep- Physical standby database
cats- Snapshot standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
You receive an error while attempting to raise the protection mode to Maximum Protection:
DGMGRL> edit configuration set protection mode as maxprotection:
Error: ORA-16627: operation disallowed since no standby databases would remain to support protection mode
Failed.
What can you conclude based on this error?

• A.Cats is a snapshot standby database.
• B.The redo transport mode is set to ASYNC for the standby database Sheep.
• C.The redo transport mode is set to ASYNC for both standby databases.
• D.The redo transport mode is set to ASYNC for the standby database Cats.
