Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q48-Q53):

NEW QUESTION # 48
Which vaults are used for storing customer-managed encryption keys for Autonomous Database on Dedicated Infrastructure?

A. Oracle Audit Vault, Oracle Key Vault
B. Oracle Database Vault, Oracle Key Vault
C. Oracle Key Vault, Oracle Cloud Infrastructure Vault
D. Oracle Cloud Infrastructure Vault, Oracle Database Vault

Answer: C

Explanation:
Autonomous Database on Dedicated Infrastructure supports customer-managed encryption (CME) keys for enhanced security control. The correct vaults are:
Oracle Key Vault, Oracle Cloud Infrastructure Vault (D):
Oracle Key Vault (OKV): A centralized key management solution designed for Oracle environments, OKV securely stores and manages encryption keys. It integrates with Autonomous Database to provide customer-managed TDE (Transparent Data Encryption) keys, offering features like key rotation and auditing. For example, a DBA might upload a master encryption key to OKV, which the database then uses to encrypt data at rest.
Oracle Cloud Infrastructure Vault (OCI Vault): OCI Vault is a general-purpose secrets management service in OCI, capable of storing encryption keys, passwords, and other sensitive data. It supports storing TDE keys for Autonomous Database, providing a cloud-native option with high availability and scalability. You might store a key in OCI Vault and link it to your database via the OCI console.
The incorrect options are:
Oracle Audit Vault, Oracle Key Vault (A): Oracle Audit Vault is for audit log management and analysis, not key storage. It doesn't support CME for Autonomous Database.
Oracle Cloud Infrastructure Vault, Oracle Database Vault (B): Oracle Database Vault enforces access controls within the database but isn't a key storage vault; it's about privilege management, not key management.
Oracle Database Vault, Oracle Key Vault (C): As above, Database Vault isn't a key storage solution, making this pairing incorrect.
Both OKV and OCI Vault offer robust security for CME, giving customers flexibility based on their infrastructure preferences (on-premises OKV vs. cloud-based OCI Vault).

NEW QUESTION # 49
Which two statements are true about accessing the Autonomous Database Tools?

A. Database Actions is accessible from a server running on the same virtual cloud network (VCN) when the Autonomous Database is configured with Private Endpoint networking.
B. Oracle Machine Learning is available only with Autonomous Data Warehouse (ADW) Database.
C. Oracle APEX can be accessed only from the Developer menu in the Service Console.
D. SQL Developer Web is exclusive to Autonomous Database, not traditional Oracle databases.
E. Access to Database Actions is available for all users of Autonomous Database.

Answer: C,D

Explanation:
Full Detailed In-Depth Explanation:
Since only four options are provided but the format requests two answers, I'll assume E from a prior question context. Let's evaluate:
A: True but conditional. Database Actions is accessible with a Private Endpoint, but requires proper network setup (e.g., VCN peering), not guaranteed by default.
B: True. Oracle APEX is accessed exclusively via the "Developer" menu in the Service Console, not other interfaces.
C: False. Oracle Machine Learning (OML) is available in both ADW and ATP, not just ADW.
D: False. Database Actions access requires specific user privileges (e.g., DWROLE), not granted to all users by default.
E (assumed): True. SQL Developer Web is exclusive to Autonomous Database, not traditional Oracle databases.
B and E are the most definitively true statements per documentation.

NEW QUESTION # 50
Which two optimizations are different between Autonomous Data Warehouse and Autonomous Transaction Processing? (Choose two.)

A. Undo Management
B. Memory Usage
C. Data Organization
D. Backup Retention

Answer: B,C

Explanation:
Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP) are optimized for different workloads, reflected in their configurations. The two differing optimizations are:
Memory Usage (A): ADW and ATP allocate memory differently to suit their purposes. ADW prioritizes a larger data cache (part of the SGA) to keep more data in memory, boosting analytical query performance (e.g., aggregations over millions of rows). For example, a SELECT SUM(sales) GROUP BY region runs faster with more cached data. ATP, conversely, balances memory across the SGA and PGA for transactional workloads, emphasizing concurrency and quick row-level operations (e.g., UPDATE orders SET status = 'shipped'). This difference ensures ADW excels at scan-heavy analytics, while ATP handles high-throughput updates.
Data Organization (B): ADW uses a columnar storage format (e.g., Hybrid Columnar Compression) optimized for analytics, storing data by column to speed up aggregations and reduce I/O (e.g., scanning only the sales column for a SUM). ATP uses a row-based format suited for OLTP, enabling fast single-row access and updates (e.g., retrieving or modifying a specific order_id). For instance, inserting a row in ATP is efficient due to row storage, while ADW's columnar format accelerates SELECT AVG(price) FROM products.
The incorrect options are:
Backup Retention (C): Both ADW and ATP use the same automatic backup system (via Oracle's Automatic Workload Repository), with a default 60-day retention adjustable by users. There's no optimization difference here; it's a shared managed feature.
Undo Management (D): Both databases use Oracle's Flashback technology for undo (e.g., rolling back transactions or querying past states), with retention periods set similarly. Undo is managed automatically in both, not optimized differently.
These optimizations tailor ADW for analytics and ATP for transactions, despite their shared autonomous foundation.

NEW QUESTION # 51
Which native data type is used to store spatial information?

A. GEO_JSON
B. SDO_GEOMETRY
C. SDO_LOCATION
D. SDO_RELATE

Answer: B

Explanation:
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.
D: GEO_JSON is a format for spatial data, not a native Oracle data type (though it can be parsed into SDO_GEOMETRY).
This type enables advanced geospatial functionality.

NEW QUESTION # 52
Which four file formats are supported when loading data from Cloud Storage?

A. AVRO
B. DOC
C. Parquet
D. JSON
E. CSV
F. DDL

Answer: A,C,D,E

Explanation:
Full Detailed In-Depth Explanation:
Supported formats:
A: False. DDL is a language, not a data format.
B: True. AVRO is supported for structured data.
C: True. Parquet is optimized for analytics.
D: False. DOC is not supported.
E: True. JSON is flexible for semi-structured data.
F: True. CSV is widely used for tabular data.
