Question No. 2

Your Data Guard environment has two remote physical standby databases.

Client applications use the local naming method to connect to the primary database instance.

You want applications to automatically connect to the new primary database instance in case of a switchover or a failover.

Which will fulfill this requirement?

ACreate a database service on each standby database that is started automatically by a trigger, when the database role is PRIMARY; modify the connection descriptors used by client applications to include all the standby hosts and connect to the database instance using that service name.

BCreate a database service on the primary database that is started automatically by a trigger, when the database role is PRIMARY; modify the connection descriptors used by client applications to include all the standby hosts and connect to the database instance using that service name.

CSet the INSTANCE_NAME parameter identically on all databases; modify the connection descriptor on client applications to include all the standby hosts and connect to the database instance using that service name.

DSet the DB_NAME and DB_UNIQUE_NAME identically on all databases; modify the connection descriptors on client applications to include all the standby hosts and connect to the database instance using that service name.

Correct Answer: A

Question No. 3

Examine the Data Guard configuration:

DGMGRL> show configuration;

Configuration Animals

Protection Mode: MaxPerformance

Databases:

dogs Primary database

sheep Snapshot 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 Availability:

DGMGDRL> edit configuration set protection mode as maxavailability;

Error: ORA-16627: operation disallowed since no standby databases would remain to support protection mode

Failed.

Identify two statements that you can execute, either one of which will enable successful raising of the protection mode to Maximum Availability. (Choose two.)

ADGMGRL> convert database sheep to physical standby;

BDGMGRL> convert database cats to physical standby;

CDGMGRL> edit database dogs set property LogXptMode= fastsync;

DDGMGRL> edit database sheep set property LogXptMode= fastsync;

EDGMGRL> edit database cats set property LogXptMode= sync;

Correct Answer: D, E

Question No. 4

You administer a Data Guard environment with a primary and two physical standby databases.

One of the physical standby databases is used for reporting and is on the same host as the primary database.

The other physical standby database is remote, used for disaster recovery and REDO is routed to it via a far sync instance.

Backups are offloaded to the remote physical standby.

Which three are true concerning the management of archive logs in this Data Guard configuration? (Choose three.)

AArchive logs on the primary database may be deleted once they are applied on all standby databases.

BArchive logs on the primary database may be deleted once they are shipped on all standby databases.

CThe deletion policy for archive logs on the remote physical standby should be set so that archived logs are deleted once they backed up at least once on the remote physical standby database.

DThe deletion policy for archive logs on the remote physical standby should be set so that archived logs are deleted once they are applied on all standby databases.

EArchive logs on the primary database may be deleted once they are archived locally to disk.

Question No. 5

Which two are prerequisites for configuring flashback database for Oracle 12c databases, in a Data Guard environment? (Choose two.)

AA flash recovery area must be configured.

BThe database must be in MOUNT state.

CThe database must be in ARCHIVELOG mode.

DA far sync instance must be configured to flash back a standby when the primary has been flashed back.

EThe Data Guard Broker must be used.

Show Answer

Correct Answer: A, C

Configure the following database settings before enabling Flashback Database:

You must have a fast recovery area enabled, because flashback logs can only be stored in the fast recovery area.

Your database must be running in ARCHIVELOG mode, because archived logs are used in the Flashback Database operation.

For Oracle Real Application Clusters (Oracle RAC) databases, the fast recovery area must be in a clustered file system or in ASM.
