Question 1

Which privilege allows a user to create tables in their own schema?

Accepted Answer

CREATE TABLE

Answer

The CREATE TABLE system privilege specifically grants a user the ability to define and create new tables within their own schema. Without this privilege, a user cannot store new relational tables in the database. This privilege is fundamental for users who need to manage their own data structures.

Question 2

A backup strategy that captures only data blocks changed since the last backup is called:

Accepted Answer

Incremental backup

Answer

An incremental backup strategy captures only the data blocks that have changed since the last backup, whether that was a full or another incremental backup. This method significantly reduces backup time and storage space by only backing up new or modified data. It is efficient for frequent backups between full backups.

Question 3

The process of applying archived redo logs to a standby database to keep it synchronized is known as:

Accepted Answer

Managed recovery

Answer

Managed recovery is the process in Oracle Data Guard where archived redo logs are automatically applied to a physical standby database. This continuous application of redo logs keeps the standby database synchronized with the primary database, ensuring data consistency and readiness for failover or switchover operations.

Question 4

Which authentication method relies on the operating system to verify database users?

Accepted Answer

OS authentication

Answer

OS authentication allows database users to be authenticated directly by the operating system, rather than by the database itself. When a user connects, Oracle trusts the operating system's verification of the user's identity. This simplifies user management by leveraging existing OS user accounts and security policies.

Question 5

The principle of least privilege suggests that users should:

Accepted Answer

Receive only necessary privileges

Answer

The principle of least privilege dictates that users, programs, or processes should be granted only the minimum set of privileges necessary to perform their required tasks. This security best practice minimizes the potential damage if an account is compromised or misused, thereby enhancing overall system security.
