1z0-931-25 Exam Dumps - Oracle Autonomous Database Cloud 2025 Professional

Scaling OCPUs in an Autonomous Database triggers a specific status update. The correct answer is:

SCALING IN PROGRESS (D):When you increase (or decrease) the number of OCPUs,the database status in the OCI console changes to “SCALING IN PROGRESS.” This indicates that the system is actively adjusting the compute resources, a process that typically completes in a few minutes with no downtime for active transactions.

The incorrect options are:

UPSCALE IN PROGRESS (A):“Upscale” is not an official status term used by Oracle for this operation.

RESIZING IN PROGRESS (B):While “resizing” might intuitively fit, Oracle specifically uses “SCALING IN PROGRESS” for CPU adjustments.

UPLIFT IN PROGRESS (C):“Uplift” is not a recognized status in the context of Autonomous Database scaling.

This status reflects Oracle’s terminology for dynamic scaling.

Autonomous Database on Dedicated Infrastructure offers unique features:

Correct Answer (A): “Users are offered greater control and isolation starting at the Exadata Cloud Infrastructure level” highlights dedicated hardware (compute, storage, network), ensuring isolation and performance not available in shared setups.

Correct Answer (E): “Users have more control over the maintenance schedule” allows scheduling maintenance windows, unlike shared infrastructure’s fixed schedules.

Incorrect Options:

B: OS customization is not allowed; Oracle manages the stack fully.

C: No OS access is provided; it’s a managed service.

Creating an Autonomous Database offers specific deployment options. The two correct ones are:

APEX Service on Dedicated Infrastructure (A):This option provisions an Autonomous Database on dedicated Exadata infrastructure with Oracle Application Express (APEX) pre-installed and optimized. It’s ideal for APEX-based apps (e.g., custom web forms) requiring isolated resources. In the OCI console, you select “Dedicated Infrastructure” and “APEX Service” as the workload type, specifying OCPUs and storage. For example, a company might deploy an APEX app for internal reporting on a dedicated ACD, ensuring performance isolation from other tenants.

Autonomous JSON Database on Shared Infrastructure (C):This creates a schema-less, JSON-centric ADB on shared infrastructure, optimized for document storage (e.g., { "order_id": 123, "items": [...] }). It’s provisioned via the OCI console under “Shared Infrastructure,” selecting “JSON Database” as the workload type. For instance, a mobile app might use it to store user data, leveraging SQL/JSON queries like SELECT JSON_VALUE(doc, '$.order_id'). It’s cost-effective and fully managed, sharing Exadata resources.

The incorrect options are:

APEX Service on Shared Infrastructure (B):There’s no distinct “APEX Service” workload type on shared infrastructure. APEX is available within ATP or ADW on shared infra, but it’s not a standalone option—you’d provision ATP and enable APEX manually, not as a dedicated “APEX Service.”

Autonomous JSON Database on Dedicated Infrastructure (D):JSON Database is onlyoffered on shared infrastructure, not dedicated. Dedicated options include ATP, ADW, and APEX Service, but JSON Database leverages shared resources for simplicity and cost.

These options cater to specific app development (APEX) and NoSQL (JSON) needs.

Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) defines four verb levels for policy permissions:

Read (B): Allows viewing resource details without modification (e.g., read autonomous-databases).

Manage (C): Permits full control, including creating, updating, and deleting resources (e.g., manage autonomous-databases).

Inspect (D): Enables listing resources and basic metadata without detailed access (e.g., inspect autonomous-databases).

Use (E): Allows interaction with resources (e.g., connecting to a database) without altering their configuration.

Incorrect Option:

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.

Oracle Database supports spatial data with a dedicated data type:

Correct Answer (A): SDO_GEOMETRY is the native data type for storing spatial information, such as points, lines, and polygons, in a structured format compatible with spatial queries and operations.

Incorrect Options:

B: SDO_LOCATION is not a valid data type; it may be a confusion with SDO_GEOMETRY.

C: SDO_RELATE is a spatial operator for relationship analysis, not a storage type.

Full Detailed In-Depth Explanation:

User and role management in Autonomous Database:

A:False. OCI console manages infrastructure, not database users.

B:True. SQL Developer provides a GUI for user/role administration.

C:False. DBMS_CLOUDADMIN is for cloud-specific tasks, not user creation.

D:True. SQL*Plus allows direct SQL commands for user/role management.

The Data Load card in Database Actions (within ADB’s web interface) simplifies data loading. The false statement is:

You must first manually create your database credentials using DBMS_CLOUD.CREATE_CREDENTIAL before accessing your Oracle Object Storage Bucket (D):This is incorrect. The Data Load card automates credential management for Oracle Object Storage by leveraging the ADB instance’s IAM permissions. When you select an OCI Object Storage bucket in the UI, it uses the instance’s resource principal or user OCI credentials (e.g., from your signed-in OCI session), eliminating the need to manually run DBMS_CLOUD.CREATE_CREDENTIAL. For example, uploading sales.csv from a bucket via the Data Load card requires only bucket selection and file mapping—no PL/SQL credential setup. This automation enhances usability, contrasting with manual methods where CREATE_CREDENTIAL is needed (e.g., in SQL scripts).

The true statements are:

Data formats supported include: text, CSV, JSON, Avro, and Parquet (A):The Data Load card supports these formats, parsing them into tables using DBMS_CLOUD under the hood. E.g., a JSON file { "id": 1, "name": "John" } loads as rows.

Data can be loaded from a local data source (B):You can upload files directly from your local machine (e.g., a CSV on your desktop) via the browser interface, staging them temporarily for loading.

Data can be uploaded from several cloud storage sources including S3, Azure, Google Cloud, and Oracle Object Storage (C):The card supports these external cloud sources, requiring credentials (e.g., AWS keys), alongside native OCI Object Storage integration.

Data can be loaded from a remote database using Database Links (E):DBLinks allow pulling data from another Oracle database (e.g., INSERT INTO local_table SELECT * FROM remote_table@link), supported in the Data Load card.

The automation of credentials in D is a key differentiator for the UI-based Data Load feature.
