Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q100-Q105):

NEW QUESTION # 100
Which three statements are true about procedures in the DBMS_CLOUD package?

A. The DBMS_CLOUD.CREATE_EXTERNAL_TABLE procedure creates an external table on files in the cloud. You can run queries on external data from the Autonomous Data Warehouse.
B. The DBMS_CLOUD.PUT_OBJECT procedure copies a file from cloud object storage to the Autonomous Data Warehouse.
C. The DBMS_CLOUD.DELETE_FILE procedure removes the credential file from the Autonomous Data Warehouse.
D. The DBMS_CLOUD.VALIDATE_EXTERNAL_TABLE validates the source file for an external table, generates log information, and stores the rows that do not match the format options specified for the external table in a bad file table in Autonomous Data Warehouse.
E. The DBMS_CLOUD.CREATE_CREDENTIAL procedure stores cloud object credentials in the Autonomous Data Warehouse.

Answer: A,D,E

Explanation:
Full Detailed In-Depth Explanation:
The DBMS_CLOUD package facilitates cloud integration:
A: True. CREATE_EXTERNAL_TABLE creates external tables for querying cloud data directly.
B: False. No DELETE_FILE procedure exists; credential management uses DROP_CREDENTIAL.
C: True. CREATE_CREDENTIAL securely stores cloud storage credentials.
D: True. VALIDATE_EXTERNAL_TABLE checks file integrity and logs errors.
E: False. PUT_OBJECT uploads files to cloud storage, not into the database.

NEW QUESTION # 101
Which three are use cases for Graph Studio? (Choose three.)

A. Clustering
B. Pattern matching
C. Facial recognition
D. 3-D modelling
E. Churn analysis

Answer: A,B,E

NEW QUESTION # 102
For someone that is not a service administrator to use SQL Developer Web, what package would you need to use to give them access?

A. ORDS_PRIV.ENABLE_SCHEMA
B. ORDS_ADMIN.ENABLE_SCHEMA
C. SQLDEV_ADMIN.GRANT_SCHEMA
D. ORDS_ADMIN.GRANT_SCHEMA

Answer: B

Explanation:
SQL Developer Web in Autonomous Database relies on Oracle REST Data Services (ORDS) for access. The correct package is:
ORDS_ADMIN.ENABLE_SCHEMA (B): To allow a non-admin user (e.g., ANALYST1) to use SQL Developer Web, the ADMIN user executes ORDS_ADMIN.ENABLE_SCHEMA to enable the schema for ORDS access. This procedure activates the schema for RESTful services, granting privileges like CONNECT and SELECT implicitly for web-based SQL execution. Example:
BEGIN
ORDS_ADMIN.ENABLE_SCHEMA(p_schema => 'ANALYST1');
END;
After this, the user accesses SQL Developer Web via a URL (e.g., https://<adb-host>/ords/analyst1/_sdw), logging in with their database credentials. This is necessary because SQL Developer Web runs on ORDS, and only enabled schemas can interact with it. For instance, an analyst might query SELECT * FROM sales in the web interface post-enablement, without needing full admin rights.
The incorrect options are:
ORDS_ADMIN.GRANT_SCHEMA (A): No such procedure exists in ORDS_ADMIN. Granting is handled via database roles/privileges (e.g., GRANT CONNECT), not a specific ORDS grant function.
ORDS_PRIV.ENABLE_SCHEMA (C): There's no ORDS_PRIV package; this might confuse with ORDS_ADMIN. The correct package is ORDS_ADMIN for schema enablement.
SQLDEV_ADMIN.GRANT_SCHEMA (D): No SQLDEV_ADMIN package exists. SQL Developer Web access is managed through ORDS, not a separate SQL Developer-specific package.
ORDS_ADMIN.ENABLE_SCHEMA is the standard, secure way to enable non-admin access to this tool in ADB.

NEW QUESTION # 103
Which statement is FALSE about loading data into the Autonomous Database using the Data Load card in Database Actions?

A. You must first manually create your database credentials using DBMS_CLOUD.CREATE_CREDENTIAL before accessing your Oracle Object Storage Bucket
B. Data can be uploaded from several cloud storage sources including S3, Azure, Google Cloud, and Oracle Object Storage
C. Data can be loaded from a remote database using Database Links (DBLinks)
D. Data formats supported include: text, CSV, JSON, Avro, and Parquet
E. Data can be loaded from a local data source

Answer: A

Explanation:
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.

NEW QUESTION # 104
Where are the customer-managed encryption keys stored for Autonomous Database on Dedicated Infrastructure?

A. On the Exadata infrastructure where the Autonomous Database Dedicated is hosted
B. Inside the Autonomous Database wallet
C. Inside the backup of the container database
D. In a separate key vault external to the Exadata infrastructure

Answer: D

Explanation:
Customer-managed encryption keys enhance security control:
Correct Answer (A): "In a separate key vault external to the Exadata infrastructure" refers to OCI Vault (Key Management Service), where keys are securely stored and managed outside the database infrastructure.
Incorrect Options:
B: The wallet secures connections, not encryption keys.
C: Storing keys on Exadata compromises separation of duties.
D: Backups don't store keys; they're encrypted by keys from the vault.
This separation ensures robust key management.
