Pass the Oracle Autonomous Database 1z0-931-25 Questions and answers with ExamsMirror

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).

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.

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 (highthroughput, 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.

Full Detailed In-Depth Explanation:

Autonomous Transaction Processing (ATP) supports specific service names for connectivity:

TPURGENT:High-priority service with 200 concurrent statements per OCPU and parallelism.

MEDIUM:Balanced service for moderate workloads.

HIGH:Optimized for reporting/batch jobs with high parallelism.

LOW:Low-priority service for minimal resource use.

TP:General-purpose transactional service.

TPPERFORMANTis not a recognized service name in ATP documentation, making A the correct answer.
