Not sure

Probably

9 / 20

What is the main advantage of using RMAN over traditional backup methods?

RMAN requires no disk space

RMAN is not recommended for large databases

RMAN provides incremental backups

10 / 20

True

False

11 / 20

What is the use of the ROLLBACK command in oracle?

It is used for dividing or breaking a transaction into multiple units so that the user has a chance of rolling back a transaction up to a point or location.

It is used in controlling the boundaries of a transaction.

It is used to undo the transactions that have not already been saved permanently to the database and get back to the initial state from where the transaction was started.

It is used for inserting / updating / deleting data to/from a table then we are performing a transaction on a table.

12 / 20

How does RMAN perform backup compression?

By compressing both datafiles and archived logs to reduce storage

By compressing only datafiles

By compressing redo logs only

By compressing only control files

13 / 20

What is the difference between a COLD BACKUP and a HOT BACKUP in Oracle?

A cold backup only backs up data files, while a hot backup includes archived logs

A cold backup is taken when the database is shut down, while a hot backup is taken while the database is running

A hot backup is a full backup, while a cold backup is incremental

There is no difference between a hot and cold backup
