Oracle 1Z0-931-25 Exam Dumps

DBMS_CLOUD.COPY_DATA loads data into Autonomous Database:

Correct Answer (B): ''The source files can reside in Oracle Object Storage, Amazon S3 Object Storage, or Azure Blob Storage'' is true. The procedure supports these cloud storage services with proper credentials.

Correct Answer (E): ''A valid credential must be created prior to running the DBMS_CLOUD.COPY_DATA procedure'' is true. Credentials (e.g., via DBMS_CLOUD.CREATE_CREDENTIAL) authenticate access to the source storage.

Incorrect Options:

A: Source files are not automatically removed; deletion requires separate action.

C: The target table must exist; COPY_DATA doesn't create it.

D: Archive Storage isn't supported; only Standard Storage is compatible.

This enables flexible data loading from cloud storage.

Graph query languages, like Oracle's Property Graph Query Language (PGQL), are designed for graph databases:

Correct Answer (D): ''Ability to specify patterns'' is a defining feature. Graph queries excel at defining and matching patterns (e.g., nodes and edges) to explore relationships, such as finding paths or subgraphs, critical for applications like social network analysis or fraud detection.

Incorrect Options:

A: Key-value queries are typical of NoSQL key-value stores, not graph databases.

B: While scripting may be possible in some contexts, it's not a core feature of graph query languages.

C: Graph query languages are not inherently object-oriented; they focus on relational graph structures.

This pattern-matching capability distinguishes graph queries from other query paradigms.

Service connections in Autonomous Database:

A . DBNAME_LOW: Optimized for high concurrency with minimal resources per query, ideal for many simultaneous queries.

B . DBNAME_MEDIUM: Balanced concurrency and performance.

C . DBNAME_HIGH: Prioritizes individual query performance, not concurrency.

D . DBNAME_CONCURRENT: Not a valid service name.

Provisioning an Autonomous Database with a private endpoint requires:

Correct Answer (A): Network Security Group (NSG) defines traffic rules for the private endpoint, restricting access to specific sources.

Correct Answer (B): VCN (Virtual Cloud Network) provides the network foundation, hosting the subnet and endpoint.

Correct Answer (E): Subnet (private) contains the database's private endpoint, isolating it from public access.

Incorrect Options:

C: Security Lists apply to subnets but are optional with NSGs, which are preferred for finer control.

D: Route Table is needed for connectivity (e.g., to a NAT Gateway), but not strictly required for the private endpoint itself.

These ensure secure, private access.

Full Detailed In-Depth Explanation:

A: True. Data Insights works with tables and business models in ADW.

B: False. Exclusive to Autonomous Database, not on-premises.

C: True. Search history is retrievable.

D: False. Included in ADW, not separately priced.
