Answer: A,C

NEW QUESTION # 148
Which four are true about duplicating a database using Recovery Manager (RMAN)? (Choose four.)

A. A new DBID is always created for the duplicated database.
B. A connection to the target database instance is always required.
C. Duplication can be done by having the auxiliary database instance pull backup sets from the target database instance.
D. Duplication can be done by having the target database instance push copies to the auxiliary database instance.
E. A subset of the target database can be duplicated.
F. A connection to the recovery catalog instance is always required.
G. A backup of the target database is always required.
H. A connection to an auxiliary instance is always required.

Answer: C,D,E,H

Explanation:
A duplicate database is a copy of your target database. With the FOR STANDBY clause, it keeps the same unique database identifier(DBID); If FOR STANDBY not specified it creates a new DBID. The duplicate database can include the same content or only a subset from the source database. It can be in the same host or a separate host. The principal work of the duplication is performed by the auxiliary channels.These channels correspond to a server session on the auxiliary instance on the destination host for backup based duplication. For active database duplication the target channels perform the work of pushing data file copies to the auxiliary instance (if number of allocated target channels is greater than the number of allocated auxiliary channels).

NEW QUESTION # 149
choose one You take regular backups of one of your production databases by using RMAN with a recovery catalog. You have added two new tablespaces to this database which must be included in future backups. Which process occurs which allows the new backups to contain the new datafiles?

A. The recovery catalog is synchronized from the target database control file with a full resync at the next backup.
B. The target database control file is synchronized from the recovery catalog with a partial resync at the next backup.
C. The recovery catalog is synchronized from the target database control file with a partial resync at the next backup.
D. The target database control file is synchronized from the recovery catalog with a full resync at the next backup.

Answer: A

NEW QUESTION # 150
Choose two. RMAN has just been connected to a target database and the recovery catalog database. In which two cases would an automatic full resynchronization occur between this target database's control file and the RMAN recovery catalog?

A. when the target is first registered
B. when control file metadata for data file backups or image copies has been overwritten in the target database's control file due to being older than CONTROL_FILE_RECORD_KEEP_TIME
C. when a backup of the current control file is created
D. when a new tablespace is added to a registered target database
E. when control file metadata for archive log backups or image copies has been overwritten in the target database's control file due to being older than CONTROL_FILE_RECORD_KEEP_TIME

Answer: A,D
