Question 3

What files should be backed up during an offline backup?
A)parameter and datafiles
B)parameter and control files
C)parameter,control,and datafiles
D)parameter,control,datafiles,and redo logs

Accepted Answer

During an offline backup, all parameter, control, and data files should be backed up to ensure a complete backup of the entire database. Redo logs are not necessary for an offline backup as they are only required for recovery purposes.

Question 4

During an online backup,the commands to rebuild your control file are placed in a(n)____ file.
A)log
B)trace
C)parameter
D)archive

Accepted Answer

During an online backup, the commands to rebuild your control file are placed in a trace file. This is because when Oracle databases perform certain operations, such as backups, they can generate trace files for diagnostic purposes, which include valuable information like control file rebuild commands.

Question 5

What is another name for an offline backup?
A)hot backup
B)cold backup
C)normal backup
D)transactional backup

Accepted Answer

A cold backup is another name for an offline backup. This type of backup involves copying data from a system or device that is not currently in use, such as a server that has been shut down or disconnected from the network. Cold backups provide an extra layer of protection against data loss or corruption, as they are not vulnerable to the same risks as live systems.

Question 7

What happens during the transition from the MOUNTED to OPEN state during startup?
A)Read the parameter file
B)Open the datafiles and redo log files
C)Open and reads the database control files
D)Processes started

Accepted Answer

During the transition from the MOUNTED to OPEN state, the database opens the datafiles and redo log files, making them accessible for queries and transactions.

Question 10

Which state follows NOMOUNT during a normal database startup?
A)SHUTDOWN
B)MOUNTED
C)OPEN
D)ONLINE

Accepted Answer

During a normal start up of the Oracle database, the state transitions are as follows:
1. NOMOUNT: Oracle reads the parameter file and creates the instance. At this stage, the database is not mounted.
2. MOUNTED: Oracle mounts the database, opening it for access without opening it for general use.
3. OPEN: Oracle opens the database for general use.

Therefore, the state that follows NOMOUNT during a normal start up is MOUNTED.

Question 11

To configure automated backups,you must designate an on-disk storage area for backup files,called the ____________________ recovery area.

Accepted Answer

The answer of To configure automated backups,you must designate an...

Question 12

During a(n)____ shutdown,the instance does not accept any new user connections,and immediately terminates current user connections.
A)Normal
B)Transactional
C)Immediate
D)Abort

Accepted Answer

An immediate shutdown is the option that immediately terminates current user connections and does not allow any new user connections to the instance. This is useful in situations where there may be issues with the database that require immediate resolution. A normal shutdown allows current transactions to complete before terminating connections, while a transactional shutdown allows current transactions to complete and then rolls back any uncommitted transactions. An abort shutdown also immediately terminates user connections, but it does not perform any instance recovery during startup.

Question 13

When performing an online backup,the database must be placed in ____ mode.
A)BACKUP
B)RECOVERY
C)ARCHIVE
D)ARCHIVELOG

Accepted Answer

When performing an online backup, the database must be in ARCHIVELOG mode. This is because ARCHIVELOG mode enables the database to continue to function while backups are being taken, by allowing the archiving of all redo log files. This ensures that all changes made to the database during the backup process can be recovered if needed.

Question 14

What task can be performed by the SYSOPER user?
A)Receive all system privileges with Admin Option
B)Create a new database within an existing database instance
C)Recover the database to a specific point in time
D)Perform database recovery operations

Accepted Answer

The SYSOPER user has limited privileges compared to the SYSDBA role, focusing primarily on operational tasks such as starting up and shutting down the database, mounting and dismounting databases, and performing basic backup and recovery operations, including database recovery.

Question 15

What does the database do first during a Normal shutdown?
A)Closes all files
B)Writes the contents of the data buffer cache to the datafiles
C)Stops all background processes
D)Writes the contents of the redo log buffer to the redo log files

Accepted Answer

During a Normal shutdown, the database first writes the contents of the data buffer cache to the datafiles to ensure all changes are committed to the database before shutting down. Once the write is complete, the database will then close all files, stop all background processes, and write the contents of the redo log buffer to the redo log files.

Question 16

A(n)____________________ server specifies the location of servers on a network.

Accepted Answer

The answer of A(n)____________________ server specifies the location of servers...

Question 18

What backup strategy is best?
A)offline backups only
B)online backups only
C)a combination of offline and online backups
D)depends on the needs of the specific organization

Accepted Answer

The best backup strategy depends on the specific needs, resources, and risk profile of the organization. Different organizations may require different approaches to ensure their data is adequately protected and recoverable in case of an incident.
