NO.56 Which TWO statements are true for Data Guard environments with multi-tenant databases?

A multi-tenant standby database can have fewer pluggable databases than the primary container database.

Different pluggable databases within a logical standby database may have different guard statuses.

The Data Guard broker automatically opens all pluggable databases of a primary database after a role change operation.

The Data Guard broker automatically always opens the pluggable databases of a standby database after a role change operation.

The CDBDBA privilege must be used instead of the SYSDBA privilege for connections as SYS to the root container of a multi-tenant standby database.

NO.57 Your Data Guard environment has two remote physical standby databases.

You want applications to automatically connect to the new primary database instance in case of a switchover or a failover.
Which set of actions will fulfill this requirement?

Set the LOCAL_LISTENER parameter for all the database instance to register services with the default listener on the primary database host.

Create 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.

Set 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.

Set 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.

NO.58 Which THREE statements are TRUE about Global Sequences when connected to a physical standby database with Real-Time Query enabled?

Their usage will always have a performance impact on the primary database.

Their creation requires that a LOG archive_dest_n parameter be defined in the standby that points back to the primary.

If the CACHE option is set then the size of the cache must be at least 100.

Their usage may have a performance impact on the physical standby database if the CACHE size is too small.

They must have the NOORDEK and CACHE options set.

NO.59 Your Data Guard environment has a remote physical standby database with real-time query enabled, which is used for reporting, and a logical standby database used for DSS reporting.
Switchovers or failovers are possible due to testing or in case of a disaster.
Clients use local TNSNAMES.ORA files to define connection strings to the database instances.
Which three will prevent clients from connecting to the wrong database instances?

Oracle Net connectivity to the primary database instance must be established on all the standby database instances.

The standby database services must be defined statically with the Listeners running on the standby database hosts.

The LOCAL_LISTENER parameter on the primary database instance must always be set.

The client applications must use the correct TNS entries when requesting connections to the database instances.

Client TNS entries for the databases use the correct service names for the intended service.

The DB_NAME and DB_UNIQUE_NAME parameters must be set to the same value for all the databases in the Data Guard environment.

A service name is registered with the local listener of each database instance.

Which three are true concerning this command?

It will execute successfully while an Oracle 19c primary database is mounted.

It will execute successfully on an Oracle 19c physical standby database while Real Time Query is active.

If executed successfully on an Oracle 19c primary database, flashback will also be enabled on all logical standby databases that are part of the configuration.

If executed successfully on an Oracle 19c primary database, flashback will also be enabled on all physical standby databases that are part of the configuration.

It will execute successfully while an Oracle 19c primary database is open.

It will execute successfully on an Oracle 19c logical standby database while SQL apply is active.

NO.63 Which two are true about managing and monitoring Oracle container databases in a Data Guard environment using the broker?

If the primary database is not a container database, then a standby may be a container database.

If the primary database is a container database, then a physical standby may be a non-container database.

If the primary database is a container database, then a logical standby may be a non-container database.

All broker actions execute at the root container for container databases.

After a role change, the broker opens all Pluggable databases (pdbb) on the new primary.

NO.64 Which TWO are TRUE about offloading backups to a physical standby database in a Data Guard environment?

The standby database must be registered in an RMAN catalog after the primary database has been registered.

The standby database can not be registered in an RMAN catalog if the primary database has not been registered.

Backups of the standby control file taken while connected to the catalog where the database is registered, may be used to restore the control file on the primary database.

The standby database must be registered in an RMAN catalog before the primary database has been registered.

NO.65 You are using Data Guard in conjunction with Global Database Services.
You have a Data Guard Broker configuration called Sales and a GDS pool called Prod.
Which three are true concerning the management of the broker configuration when using GDS?

DGMGRL may be used to add the Sales configuration to the Prod pool in gds.

Performing a role change with DGMGRL automatically notifies GDS which in turn activates the appropriate services.

DGMGRL may be used to add a single database to the Sales configuration even if Sales is a member of the Prod pool.

Adding a database to the Sales configuration with DGMGRL automatically adds the database to the Prod Pool.

Adding a database to the Sales configuration with DGMGRL requires that the Sales configuration be disabled first. It must then be enabled after the new database is added to the configuration.
