問題 #45
Which three statements are true about redo transport?

A. With synchronous redo transport, LGWR ships redo directly to RFS processes on the standby database instances and waits for an acknowledgment.
B. Multiple RFS processes may receive redo on one standby database instance.
C. With asynchronous redo transport, TTnn processes may read redo from the log buffer or from standby redo logs on the primary database.
D. Multiple RFS processes may receive redo on one far sync instance.
E. An RFS process on a standby database instance may receive redo from an archiver process on the primary database instance to perform archive gap resolution.

答案：A,B,E

問題 #46
A Data Guard environment has this configuration and these attributes:
A primary database
A physical standby database named sbdb
The configuration is in maximum availability protection mode.
Then sbdb is converted to a snapshot standby database.
Which two statements are true?

A. The protection mode is lowered to maximum performance.
B. sbdb can still apply redo.
C. sbdb can still receive redo.
D. The recovery point objective increases.
E. The recovery time objective increases.

答案：C,D

問題 #47
Which two are prerequisites for configuring Transaction Guard in a Data Guard environment?

A. Grant execute permission on the DBMS_APP_CONT package to relevant database schema owners.
B. Set INSTANCE_NAME identically on all the Data Guard Configuration databases and modify the local service name on the client to include a CONNECTION_LIST containing all the standby hosts.
C. Create a database service with COMMIT_OUTCOME set to TRUE and ensure that the service is statically registered with the default listener on the primary host.
D. Ensure that connection descriptors for database clients use the failover clause with the COMMIT_OUTCOME parameter set to TRUE.
E. Create a database service with COMMIT_OUTCOME set to TRUE, and ensure clients use that service to connect to the database instance.

答案：A,E

問題 #48
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?

A. 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.
B. Configure a PRIMARY role service on the Primary and Standby and modify the Client connect descriptor to include both the Primary and the Standby.
C. Set the LOCAL_LISTENER parameter for all the database instances, to register services with the default listener on the primary database host.
D. Create a database service on the standby databases; automate the start of the service after a role change, and modify the connection descriptor on the clients to use that service.

答案：D

問題 #49
You have a Data Guard Broker configuration called 'Somewhere' as shown:
DGMGRL> SHOW CONFIGURATION;
Configuration - Somewhere
Protection Mode: MaxPerformance
Databases:
Nearby - Primary database
FS - Far Sync
Farout - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
You then run this command:
DGMGRL> SHOW DATABASE 'Nearby' 'InconsistentProperties';
Which two are true about the output of this DGMGRL command?

A. Any inconsistency reported is on an instance-specific basis.
B. It shows all properties whose broker configuration values for database Nearby are inconsistent with the broker configuration values for database Farout.
C. It shows all properties whose broker configuration values for database Nearby are inconsistent with the values in the corresponding server parameter file or the runtime values for database instance Nearby.
D. A far sync instance cannot have inconsistent properties because it has no database.

答案：C,D

問題 #50
