Oracle Database Administration II Exam Practice Test

Oracle Database Administration II focuses on operational database administration, including recovery planning, instance memory, auditing, user controls, and performance support. Practice topics also touch on transaction behavior, temporary tablespaces, optimizer statistics, bulk data loading, and diagnostic logs. These areas connect routine DBA decisions with database availability, security, and reliable application data access.

About the Oracle Database Administration II Exam

Effective administration requires choosing the right recovery approach for a failure scenario, understanding how backup files and redo support point-in-time recovery, and managing the fast recovery area. Memory questions concern instance parameters such as SGA_TARGET and their role in automatic shared memory management. Security-related tasks include tracking administrative changes and using user profiles to control account behavior. Other operational skills include distinguishing temporary storage from permanent data, committing transactions, gathering optimizer statistics with DBMS_STATS, and loading formatted files with SQL*Loader. Alert-log interpretation supports investigation of database events and errors. These topics involve recognizing what each Oracle feature does and when it fits an administrative task; they do not establish official exam coverage or topic weighting.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A database is configured with a fast recovery area. Which statement best describes its purpose?

  1. AIt stores recovery-related files such as archived redo logs and RMAN backups, subject to space management policies.
  2. BIt holds all currently active user sessions and their cursors.
  3. CIt replaces the database's control files and online redo logs.
  4. DIt automatically stores every database object in compressed form.
Show answerCorrect answer: A

The fast recovery area is a centralized storage location for recovery-related files, including eligible backups, archived redo logs, and flashback logs. Its space usage is managed according to configuration and retention requirements; it does not replace core database structures or store session state.

Question 2

A DBA wants to record administrative activity, such as changes to users and privileges, for later review. Which Oracle capability is intended for this purpose?

  1. ADatabase auditing
  2. BSegment advisor
  3. CAutomatic Workload Repository snapshots
  4. DResult cache
Show answerCorrect answer: A

Oracle auditing can record selected database actions and security-relevant events for review, subject to the auditing configuration and available audit policies. Segment advisor analyzes space use, AWR snapshots capture performance statistics, and the result cache stores query results or function results.

Question 3

What does the Oracle instance parameter SGA_TARGET control when automatic shared memory management is in use?

  1. AThe target total size of the System Global Area
  2. BThe maximum number of concurrent user sessions
  3. CThe size of each datafile in the database
  4. DThe retention period for archived redo logs
Show answerCorrect answer: A

SGA_TARGET specifies a target size for the SGA. Oracle can adjust the sizes of eligible SGA components to manage memory within that target, subject to other parameter settings.

Question 4

What is the main purpose of an Oracle profile assigned to a user?

  1. ATo define password and resource limits for the user
  2. BTo specify the user's default datafile
  3. CTo grant ownership of all objects in a schema
  4. DTo choose the instance's character set
Show answerCorrect answer: A

A profile can impose password-management settings and, when resource limits are enabled, resource limits for users assigned to it. It does not grant object ownership or determine a datafile or character set.

Question 5

Which type of Oracle backup contains enough information to restore a database to a point in time when combined with the required redo?

  1. AA consistent physical backup taken only after the database is shut down normally
  2. BAn inconsistent physical backup taken while the database is open
  3. CA text file containing only initialization parameter values
  4. DA Data Pump export of selected schemas
Show answerCorrect answer: B

An open-database physical backup can be inconsistent because datafiles may reflect different points in time. With the necessary archived redo and recovery procedures, Oracle can make the restored files consistent to a target point in time.

Question 6

Which SQL command makes a transaction's changes permanent and visible to other sessions?

  1. ASAVEPOINT
  2. BROLLBACK
  3. CCOMMIT
  4. DDISCONNECT
Show answerCorrect answer: C

COMMIT ends the current transaction and makes its changes permanent. SAVEPOINT marks a point within a transaction, while ROLLBACK reverses uncommitted changes.

Question 7

Which statement about a temporary tablespace is correct?

  1. AIt is used for temporary operations such as sorts that exceed available memory
  2. BIt stores the database's permanent data dictionary tables only
  3. CIt is required to keep online redo log members
  4. DIt prevents users from creating permanent schema objects
Show answerCorrect answer: A

Temporary tablespaces provide space for operations such as large sorts and hash operations when they cannot be completed in memory. They are separate from ordinary permanent storage for persistent table data.

How to use this practice test

Access the free question bank to work through a session of up to 20 randomly selected questions from the published set of 50. After the session, review the results and use any missed items to identify Oracle concepts that need further practice, such as recovery choices, memory management, auditing, or data loading.

Preparation tips

  • For recovery scenarios, distinguish backup types and map the role of redo when restoring to a target point in time; review how the fast recovery area supports recovery files.
  • Practice interpreting SGA_TARGET in the context of automatic shared memory management, and identify which memory components the setting can influence.
  • Compare auditing administrative activity with user-profile controls; be able to explain the different security purpose each serves.
  • Review the practical use of DBMS_STATS, SQL*Loader, temporary tablespaces, transaction COMMIT, and the alert log in routine DBA work.
