You execute the commands to configure settings in RMAN: RMAN> CONFIGURE DEVICE TYPE sbt PARALLELISM 1; RMAN> CONFIGURE DEFAULT DEVICE TYPE TO sbt;
RMAN> CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE sbt TO 2; RMAN> CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE sbt TO 2; RMAN> CONFIGURE DATAFILE BACKUP COPIES FOR DRVICE TYPE DISK TO 2;
Then you issue the following command to take a backup: RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which statement is true about the execution of these commands? Choose the best answer.
Correct Answer:B

Examine the backup requirement for your company:
1) Every Sunday, a backup of all used data file blocks is performed.
2) Every Wednesday and Friday, a backup of all the changed blocks since last Sunday's backup is performed.
3) On all the other days, a backup of only the changed blocks since the last day's backup is performed.
Which backup strategy satisfies the requirements?
Correct Answer:A
Multilevel Incremental Backups RMAN can create multilevel incremental backups. Each incremental level is denoted by a value of 0 or 1. A level 0 incremental backup, which is the base for subsequent incremental backups, copies all blocks containing dat
A. You can create a level 0 database backup as
backup sets or image copies. The only difference between a level 0 incremental backup and a full backup is that a full backup is never included in an incremental strategy. Thus, an incremental level 0 backup is a full backup that happens to be the parent of incremental backups whose level is greater than 0. A level 1 incremental backup can be either of the following types: A differential incremental backup, which backs up all blocks changed after the most recent incremental backup at level 1 or 0. A cumulative incremental backup, which backs up all blocks changed after the most recent incremental backup at level 0. Incremental backups are differential by default.
Which three statements are true about Oracle Secure Backup (OSB)?
Correct Answer:ACE
File system backups may be performed at the file, directory, file system or raw partition level with full, incremental and offsite backup scheduling. As backup needs grow requiring more tape drives and centralized backup management of multiple servers, Oracle Secure Backup XE can be easily upgraded to the Oracle Secure Backup edition. http://www.oracle.com/technetwork/products/secure-backup/learnmore/osb-xe-10-130649.pdf
Which two statements are true about a multitenant architecture?
Correct Answer:CD
You are only able to switch the archived logs when you connect to the root of a CDB, but you cannot switch archived redo logs when connected to a PDB. You can able to create a PDB without temporary tablespace but not able to make it use the temporary tablespace of CDB.
You want RMAN to make duplicate copies of data files when using the backup command. What must you set using the RMAN configure command to achieve this?
Correct Answer:D
Configuring Backup Duplexing You can use the CONFIGURE ... BACKUP COPIES command to specify how many copies of each backup piece should be created on the specified device type for the
specified type of file. This type of backup is known as a duplexed backup set. The CONFIGURE settings for duplexing only affect backups of datafiles, control files, and archived logs into backup
sets, and do not affect image copies. NOT A The CONFIGURE MAXSETSIZE command limits the size of backup sets created on a channel. This CONFIGURE setting applies to any channel, whether manually allocated or configured, when the BACKUP command is used to create backup sets. The default value
is given in bytes and is rounded down to the lowest kilobyte value. Reference: http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmconfa.htm#BRADV137
