Answer : B

Autonomous Database allows independent scaling of certain resources:

Correct Answer (B): ''Storage'' can be scaled independently of OCPUs via the OCI Console or API, adjusting capacity (e.g., from 1 TB to 2 TB) without altering compute resources.

Incorrect Options:

A: Sessions depend on CPU and memory limits, not independently scalable.

C: Memory scales with OCPUs in a fixed ratio, not separately.

D, E: Concurrency and parallelism are tied to CPU resources and consumer group settings.

This flexibility optimizes cost and capacity management.

Answer : B

Keeping Autonomous Database tables synchronized with an on-premises data source involves loading and updating data from external locations. The Cloud Locations card on the Data Load page is the correct method:

Correct Answer (B): The Cloud Locations card allows users to connect to Oracle Cloud Infrastructure (OCI) Object Storage buckets and load data into Autonomous Database tables. By regularly updating the data in Object Storage from the on-premises source (e.g., via scripts or tools), you can maintain synchronization using this feature. It supports automated data loading workflows when paired with appropriate processes.

Incorrect Options:

A: Oracle REST Data Services (ORDS) is used for building RESTful web services, not for direct data synchronization from on-premises sources to Autonomous Database tables.

C: The Link Data option enables linking to external database tables (e.g., via database links), but it doesn't inherently synchronize data; it provides access rather than replication.

D: There is no ''FEED DATA'' option on the Data Load page in Autonomous Database; this appears to be a fabricated choice.

This method leverages OCI Object Storage as an intermediary, making it a practical solution for ongoing synchronization.

Answer : A, C

Private endpoints enhance security for Autonomous Database:

Correct Answer (A): ''A Network Security Group is required within your Virtual Cloud Network before you can provision a shared Autonomous Database to use private endpoints'' is true. An NSG is mandatory to define ingress/egress rules for the private subnet hosting the endpoint.

Correct Answer (C): ''Private endpoints can be configured when you clone a shared Autonomous Database that was initially created with public endpoints'' is true. Cloning allows switching to a private endpoint configuration.

Incorrect Options:

B: Private endpoints are inaccessible from the public internet, even with ACLs; that's their purpose.

D: Always Free tier doesn't support private endpoints; it's limited to public access.

This ensures isolated, secure connectivity.

Answer : C

Autonomous Database on dedicated infrastructure supports multiple workload types. The correct answer is:

ATP and ADW (C): Autonomous Database on dedicated infrastructure supports both Autonomous Transaction Processing (ATP) for OLTP workloads (high concurrency, low latency) and Autonomous Data Warehouse (ADW) for analytical workloads (high throughput, complex queries). This dual support allows flexibility within a single dedicated Exadata infrastructure.

The incorrect options are:

Autonomous Transaction Processing only (A): Incorrect, as ADW is also supported.

Hybrid Columnar Compression (B): HCC is a data compression feature, not a workload type; it's used within ADW but doesn't define the workload.

Autonomous Data Warehouse only (D): Incorrect, as ATP is also supported.

This versatility is a key feature of dedicated deployments.

Answer : C

Oracle Autonomous Database on Dedicated Infrastructure enforces automatic maintenance to ensure security, stability, and performance. The correct answer is:

You cannot permanently disable scheduled Automatic Maintenance (C): Oracle mandates periodic maintenance updates (e.g., patching) to keep the database secure and compliant with the latest fixes. Customers can influence the timing of these updates but cannot disable them permanently. This is a design principle of the Autonomous Database service to reduce administrative overhead while maintaining system integrity.

The incorrect options are:

Change the Automatic Maintenance Schedule to 'No Preference' (A): This setting allows Oracle to determine the maintenance window but does not disable maintenance. It still occurs as scheduled by Oracle.

Change the Automatic Maintenance Schedule to 'None' (B): There is no 'None' option in the maintenance scheduling settings for Autonomous Dedicated Infrastructure. This is not a valid configuration.

Change the Automatic Maintenance Schedule to 'Specify a Schedule' but do not select any month, week, or day (D): This is not a functional workaround. Specifying a schedule requires selecting a valid time window, and leaving it blank does not prevent maintenance; it simply reverts to Oracle's default scheduling.

Oracle's documentation confirms that while customers can reschedule or skip specific maintenance runs (up to two consecutive quarters), permanently disabling automatic maintenance is not permitted to ensure the system remains up-to-date and secure.
