If the former primary database became a logical standby database it will be in mount state

Question 3

Your expertise is requested for these customer requirements:

4. The primary database must be resilient in case of a single network failure. Which solution is correct for these requirements?

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

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

one physical standby database with Real-Time Query enabled, receiving redo from two Far Sync instances that are connected the primary

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

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.

Question 4

Which two are prerequisites for enabling Automatic Block Media Recovery in a Data Guard environment consisting of a primary database, one physical standby database and one logical standby database?

FLASHBACK DATABASE must be enabled on the physical standby database.

There must be connectivity between the primary and the physical standby database.

FLASHBACK DATABASE must be enabled on the primary database.

The physical standby database must have Real-Time Apply enabled.

The logical standby database must have Real-Time Query enabled

Question 5

On your logical standby database, you specified these rules:
1Z0-066 dumps exhibit

Which is true regarding the execution of the UNSKIP procedure?

it succeeds only if SQL apply is stopped before deleting the SQL Apply filter

it succeeds but the SQL Apply fitters are not deleted.

It deletes both the SQL Apply filters.

it returns an error because the syntax to delete a SQL Apply filter must specify the same object names as specified when the filter was added

it succeeds only if all DML statements executed on the primary have been applied on the logical standby

Question 6

Your Data Guard environment has two remote physical standby databases.
Client applications use the local naming method to define connectivity to the primary database instance.
Which will automatically redirect clients to the new primary database in case of a switchover or failover?

Create a database service on the standby databases; automate the start of the service after a role change, and modify the connection description on the clients to use that service.

Configure a PRIMARY role service on the Primary and Standby and modify the Client connect descriptor to include both Primary and the Standby.

Set the DB_NAME parameter identically on all databases; modify the connection descriptor on the clients to use DB_NAME to connect to the primary database instance.

Set the LOCALJJSTENER parameter for all the database instances, to register services with the default listener on the primary database host.

Question 7

Increase the PROCESSES initialization parameter

Increase the value for the MAX_SERVERS SQL apply parameter.

Decrease the number of archiver processes on the standby databas

increase the PARALLEL_MAX_SERVER initialization parameter

Decrease the number of PREPARER processes

Increase the RECOVERY_PARALLEUSM initialization parameter

Question 8

A query on the view DBA_LOGSTDBY_UNSUPPORTED on your primary database returns several rows.
As a result of this, you decide that an upgrade may not use logical standby databases
Which three are true about upgrading Data Guard environments consisting of one physical standby database running on a separate host from the primary?

The upgrade requires downtime until the upgrade of the standby is completed.

The broker must be disabled during the upgrade

With manual upgrade, catupgrd.sql can be executed on the primary and standby databases simultaneously.

The upgrade requires downtime until the upgrade of the primary is completed.

The new release of the Oracle Software must be installed on both the primary and standby database hosts

Redo Apply on the standby database must be stopped while the primary database is upgraded.

Fast-Start Failover can be used to protect the primary database during the upgrade.

Question 9

Examine the Data Guard configuration:
1Z0-066 dumps exhibit

Which three will be true after a switchover to Sheep?

Dogs will be an enabled logical standby database.

Sheep will be the primary database.

Cats will be a disabled physical standby database.

Dogs will be a disabled logical standby database

Cats will be an enabled physical standby database.

Question 10

The broker must be disabled during the upgrade

With manual upgrade, catupgrd.sql can be executed on the primary and standby databases simultaneously.

The upgrade requires downtime until the upgrade of the primary is completed.

The new release of the Oracle Software must be installed on both the primary and standby database hosts

Redo Apply on the standby database must be stopped while the primary database is upgraded.

Question 11

Which three are among the various tasks performed by the data Guard Monitor (DMON) process?
