Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q43-Q48):

NEW QUESTION # 43
What two actions can you do when a refreshable clone passes the refresh time limit? (Choose two.)

A. You can manually refresh the clone
B. You can use the instance as a read-only database
C. You can extend the refresh time limit
D. You can disconnect from the source to make the database a read/write database

Answer: B,D

Explanation:
A refreshable clone in Autonomous Database is a read-only copy of a source database that syncs periodically, but it has a refresh time limit (typically 7 days). Once this limit is exceeded, specific actions are available. The two correct options are:
You can disconnect from the source to make the database a read/write database (B): After the refresh time limit passes, the clone can no longer sync with the source. You can "disconnect" it (via the OCI console or API, e.g., oci db autonomous-database update --is-refreshable-clone false), converting it into an independent, read/write Autonomous Database. This requires a new license and incurs full costs, but it allows modifications (e.g., INSERT or UPDATE) that were blocked in read-only mode. For example, a test clone might be disconnected to become a production instance after testing.
You can use the instance as a read-only database (C): Even after the refresh limit, the clone remains functional as a read-only database, retaining its last refreshed state. You can query it (e.g., SELECT * FROM sales) for analysis or reporting without further refreshes, though it won't reflect source updates. This is useful if ongoing read-only access suffices without needing write capabilities.
The incorrect options are:
You can manually refresh the clone (A): False. Once the refresh time limit (e.g., 7 days) is exceeded, manual refreshes are not possible. The clone's refresh capability expires, and it can't sync again unless recreated. This is a fixed constraint to manage resource usage in ADB.
You can extend the refresh time limit (D): False. The refresh period (set during clone creation, max 7 days) cannot be extended after provisioning. You'd need to create a new clone with a longer limit if needed, but post-expiry, no extension is allowed.
These options provide flexibility post-expiry, balancing read-only continuity and full database conversion.

NEW QUESTION # 44
Which method does NOT permit you to change the database ADMIN user's password of an Oracle Autonomous Database on Shared Infrastructure?

A. Admin page of the Cloud Service Console
B. SQL Developer
C. OS command line from the database server
D. OCI CLI

Answer: C

Explanation:
Changing the ADMIN user's password in an Autonomous Database on Shared Infrastructure is restricted to specific managed methods due to its serverless nature:
Correct Answer (C): "OS command line from the database server" is not permitted because Autonomous Database is fully managed by Oracle. Users do not have direct access to the underlying operating system or server, eliminating this as a viable option.
Valid Methods:
A: The Admin page in the OCI Console allows password changes via the "Change Administrator Password" option, a user-friendly GUI method.
B: The OCI CLI supports password updates using commands like oci db autonomous-database update with the --admin-password parameter.
D: SQL Developer can change the password using an ALTER USER ADMIN IDENTIFIED BY <new_password> command, provided the user has appropriate credentials.
This restriction ensures security and consistency in a managed environment.

NEW QUESTION # 45
Which two statements are true about the Oracle Cloud Infrastructure (OCI)? (Choose two.)

A. An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region.
B. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
C. Regions are dependent on other regions and must be located within 5 thousand kilometers of each other.
D. A single fault domain can be associated with multiple regions and availability domains.

Answer: A,B

Explanation:
Oracle Cloud Infrastructure (OCI) is designed with a hierarchical structure to ensure high availability and fault tolerance:
Correct Answer (B): "An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region" accurately describes OCI's architecture. A region is a standalone geographic area (e.g., US East), and availability domains (ADs) are isolated data centers within that region, enhancing resilience.
Correct Answer (D): "Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region" reflects OCI's design for fault isolation. ADs are physically separate, minimizing the risk of cascading failures.
Incorrect Options:
A: Regions are independent, not dependent, and there's no 5,000-kilometer restriction; they are globally distributed for latency and redundancy purposes.
C: Fault domains are subdivisions within an AD, not across regions or ADs, ensuring resource isolation within a single AD.
This structure supports robust disaster recovery and high availability.

NEW QUESTION # 46
Given the steps:
Create Oracle Machine Learning User
Create Projects
Create Workspaces
Create Notebooks
Run SQL Scripts
Which two steps are out of order when working with Oracle Machine Learning?

A. Create Projects
B. Create Notebooks
C. Create Workspaces
D. Run SQL Scripts
E. Create Oracle Machine Learning User

Answer: A,C

Explanation:
Full Detailed In-Depth Explanation:
The correct sequence for Oracle Machine Learning (OML) is:
Create Oracle Machine Learning User: First step to enable OML access.
Create Workspaces: Containers for organizing projects.
Create Projects: Groups for related notebooks within a workspace.
Create Notebooks: Environments for coding and analysis.
Run SQL Scripts: Executed within notebooks.
In the given list, Create Projects (2) comes before Create Workspaces (3), which is reversed. Workspaces must exist before projects. Thus, C and D are out of order.

NEW QUESTION # 47
While creating an Autonomous Container Database on dedicated infrastructure through the Oracle Cloud Infrastructure (OCI) console, which patch type is offered to be applied during maintenance?

A. Release Update (RU)
B. Prior Release Update Revision (PRUR)
C. Quarterly Bundle Patch (QBP)
D. Prior Release Update (PRU)

Answer: A

Explanation:
When creating an Autonomous Container Database (ACD) on dedicated infrastructure, Oracle offers specific patch types for maintenance. The correct answer is:
Release Update (RU) (D): During the creation of an ACD via the OCI console, users can choose to apply a Release Update (RU), which includes the latest security patches, bug fixes, and enhancements for the database version. RUs are the standard patching mechanism for Autonomous Databases on dedicated infrastructure, ensuring the system stays current.
The incorrect options are:
Quarterly Bundle Patch (QBP) (A): QBPs are not a recognized patch type for Autonomous Databases; they are more associated with on-premises Oracle deployments, not the cloud-native Autonomous infrastructure.
Prior Release Update Revision (PRUR) (B): PRURs are minor updates to prior releases, but they are not offered as a distinct option during ACD creation; Oracle focuses on RUs for consistency.
Prior Release Update (PRU) (C): PRUs refer to updates from previous major releases, but Autonomous Databases typically apply the latest RU, not prior ones, during provisioning or maintenance.
RUs align with Oracle's strategy for maintaining Autonomous Databases.
