Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q83-Q88):

NEW QUESTION # 83
Which are the two restrictions for an Always Free Autonomous Database? (Choose two.)

  • A. Supports only ATP as a workload type
  • B. Oracle Application Express (APEX) not included
  • C. Maximum of two Always Free Databases per OCI tenancy
  • D. Maximum of one OCPU per Database

Answer: C,D

Explanation:
The Always Free tier of Autonomous Database has specific limits. The two correct restrictions are:
Maximum of two Always Free Databases per OCI tenancy (B): OCI's Always Free tier allows up to two free ADB instances per tenancy (e.g., one ATP, one ADW). This limit ensures fair resource distribution across users. For example, you might create FREEATP1 (1 OCPU, 20 GB) and FREEADW1 (1 OCPU, 20 GB) in your tenancy, but a third free instance isn't permitted-you'd need a paid upgrade. This is tracked by tenancy OCID, visible in the OCI console under "Limits." Maximum of one OCPU per Database (D): Each Always Free ADB is capped at 1 OCPU, non-scalable, with 20 GB of storage. This restricts compute power (e.g., no auto-scaling to 3x like paid tiers), suitable for small workloads like dev/test apps. For instance, a free ATP instance runs a lightweight app with SELECT * FROM users, but can't handle heavy concurrency due to the single OCPU.
The incorrect options are:
Supports only ATP as a workload type (A): False. Always Free supports both ATP (transactional) and ADW (warehouse) workload types, giving flexibility for OLTP or analytics (e.g., ATP for a web app, ADW for reports).
Oracle Application Express (APEX) not included (C): False. APEX is included in both free ATP and ADW instances, pre-installed and accessible via the OCI console (e.g., "Development" > "APEX"). You can build apps like a task tracker without extra cost.
These restrictions balance free access with resource constraints, encouraging upgrades for heavier use.


NEW QUESTION # 84
What is a best practice when planning and instituting access controls for your Autonomous Dedicated environment regarding subnets, compartments, and user groups?

  • A. Create at least 2 of each resource.
  • B. Only 1 subnet and 1 compartment are allowed, multiple groups highly advised.
  • C. Only 1 of each is allowed to be allocated per environment.
  • D. Create a separate VCN that contains only public subnets.

Answer: A

Explanation:
When designing access controls for an Autonomous Dedicated environment, Oracle recommends redundancy and separation for security and manageability:
Correct Answer (D): "Create at least 2 of each resource" (subnets, compartments, user groups) is a best practice:
Subnets: Using at least two subnets (e.g., one public, one private) enhances security by segregating traffic and provides failover options if one subnet encounters issues.
Compartments: Multiple compartments allow logical separation (e.g., dev, test, prod), simplifying access control and resource management.
User Groups: At least two groups (e.g., admins, developers) streamline permission assignments and reduce the risk of over-privileging users.
Incorrect Options:
A: OCI allows multiple subnets and compartments; restricting to one limits flexibility and security.
B: There's no such limitation; multiple resources are supported and encouraged.
C: A VCN with only public subnets contradicts security best practices, as private subnets are critical for database isolation.
This approach aligns with Oracle's guidance for secure and scalable deployments.


NEW QUESTION # 85
You want to enable automatic indexing in a database, but any new auto indexes should be created as invisible indexes, so that they cannot be used in SQL statements. Which command will you use?

  • A. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','OFF')
  • B. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','IMPLEMENT')
  • C. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','REPORT ONLY')
  • D. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','INVISIBLE')

Answer: C

Explanation:
Oracle's automatic indexing feature, available in Autonomous Database, optimizes query performance by creating and managing indexes. The requirement here is to enable it but ensure new indexes are invisible (not used by the optimizer unless explicitly made visible). The correct command is:
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','REPORT ONLY') (C): The REPORT ONLY mode enables automatic indexing, where the database identifies and creates candidate indexes based on workload analysis. However, these indexes are created as invisible by default, meaning the optimizer does not use them in SQL execution plans unless a DBA manually makes them visible (e.g., via ALTER INDEX ... VISIBLE). This mode is ideal for testing or validation without impacting production queries. For example, if a query frequently filters on a column, an invisible index might be created, but it won't affect performance until explicitly activated.
The incorrect options are:
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','IMPLEMENT') (A): The IMPLEMENT mode fully enables automatic indexing, creating and maintaining visible indexes that the optimizer uses immediately. This contradicts the requirement for invisible indexes.
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','OFF') (B): The OFF mode disables automatic indexing entirely, so no indexes (visible or invisible) are created, failing the requirement to enable it.
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','INVISIBLE') (D): There is no INVISIBLE mode in DBMS_AUTO_INDEX.CONFIGURE. While indexes can be set as invisible individually, this is not a valid configuration option for the auto-indexing feature.
The REPORT ONLY mode provides a controlled approach, allowing index creation for analysis without immediate deployment. This is particularly useful in Autonomous Database, where automation is balanced with DBA oversight.


NEW QUESTION # 86
Data Guard is enabled for your Autonomous Database and the Lifecycle State field for the primary database indicates that it is Stopped. Which statement is true?

  • A. Standby database is also stopped.
  • B. Failover is automatically initiated.
  • C. Switchover is automatically initiated.
  • D. Standby database is terminated.

Answer: A

Explanation:
With Autonomous Data Guard enabled, the primary and standby databases are tightly coupled:
Correct Answer (C): "Standby database is also stopped" is true. When the primary database is stopped (e.g., via OCI Console), the standby database is also stopped to maintain consistency and alignment between the two. This ensures the standby remains a viable replica when the primary restarts.
Incorrect Options:
A: Switchover (role reversal) requires manual initiation and an active primary; it doesn't occur automatically on stop.
B: The standby is not terminated; it remains configured but stopped.
D: Failover (standby promotion) is not automatic on a planned stop; it's triggered only by primary failure.
This behavior preserves Data Guard functionality.


NEW QUESTION # 87
Oracle Data Safe is a unified control center for your Oracle databases that helps you understand the sensitivity of your data, evaluate risks to data, mask sensitive data, implement and monitor security controls, assess user security, monitor user activity, and address data security compliance requirements. Which statement is FALSE?

  • A. Oracle Data Safe helps you find sensitive data in your database by inspecting the actual data in your database and its data dictionary.
  • B. Oracle Data Safe only supports Autonomous Databases.
  • C. Oracle Data Safe evaluates user types, how users are authenticated, and the password policies assigned to each user.
  • D. Oracle Data Safe helps you assess the security of your cloud database configurations by analyzing database configurations.

Answer: B

Explanation:
Full Detailed In-Depth Explanation:
Oracle Data Safe enhances database security across various deployments. Let's evaluate:
A: True. Data Safe assesses cloud database configurations for vulnerabilities.
B: True. It evaluates user authentication, types, and password policies.
C: False. Data Safe supports Autonomous Databases, Exadata Cloud Service, OCI VMs, and on-premises Oracle databases, not just Autonomous Databases.
D: True. It scans data and metadata to identify sensitive information.
Option C is the false statement, as Data Safe's scope extends beyond Autonomous Databases.
