Oracle Cloud Database Services 2025 Professional Sample Questions (Q62-Q67):

NEW QUESTION # 62
When a new security patch is released for the Oracle Database software on a BaseDB VM system, what is the recommended approach for applying it in a production environment?

A. Apply the patch to a production standby database (if one exists) and then failover to the patched standby.
B. Wait for Oracle Cloud Infrastructure to automatically apply the security patch to all BaseDB VM systems.
C. Immediately apply the patch directly to the production database during off-peak hours to minimize potential security vulnerabilities.
D. Download the patch and apply it to a non-production environment that mirrors the production environment for testing before applying it to production.

Answer: D

Explanation:
B: Testing patches in a non-production environment:
* Critical to ensure that the patch does not introduce performance issues or compatibility problems.
* Best Practice:Apply the patch to astaging environmentthat mirrors production, validate stability, and then proceed to production.
* Minimizes the risk of unplanned downtime or disruptions.
Why the other options are incorrect:
* A. Immediate application in production:Risky as untested patches might cause outages.
* C. Automatic patching by OCI:OCI does not automatically apply database patches; the customer must manage this.
* D. Patching the standby and failing over:While a good strategy when applicable, it still requires prior testing.

NEW QUESTION # 63
Which two of the following describe capabilities of the Database Management service in relation to database parameter management?

A. Database Management provides recommendations for parameter tuning based on historical performance data.
B. Database Management does not offer parameter management capabilities due to security concerns.
C. Database Management can automatically detect and correct parameter settings that deviate fromOracle- recommended best practices, regardless of the database edition.
D. Database Management facilitates comparing parameter settings between different databases or across different points in time for a single database.

Answer: A,D

Explanation:
B: Recommendations for parameter tuning:
* Database Management analyzes historical performance data and provides tuning recommendations.
* These recommendations align with Oracle best practices to optimize database performance.
C: Comparison of parameter settings:
* The service allows users to compare parameter configurations between different databases or across time points for a single database.
* This is useful for identifying changes or discrepancies that could impact performance.
Why the other options are incorrect:
* A. Automatic correction of parameters:Database Management does not automatically correct parameters; changes require manual intervention.
* D. Lack of parameter management:Incorrect statement, as the service does offer parameter management features.

NEW QUESTION # 64
Within the context of Exadata Database Service, what does scaling out primarily refer to?

A. Increasing the CPU core count of a single database server VM.
B. Adding additional database server VMs and storage servers to the Exadata system.
C. Upgrading the version of the Oracle Database software.
D. Expanding the amount of RAM available to a single database instance.

Answer: B

Explanation:
Scaling Out:
Scaling out in Exadata means increasing thenumber of database server VMs and storage serversto handle a larger workload. This is achieved byadding more compute nodesand storage cells, allowing the system to distribute database processingacross multiple nodes.
This horizontal scalability is ideal for environments with fluctuating workloads or growing data volumes. It improvesquery performance and fault tolerancesince data and workload are distributed across more hardware resources.
Why the other options are incorrect:
* A:Increasing CPU cores within a single VM is consideredscaling up.
* C:Upgrading the database software version is unrelated to scaling.
* D:Increasing RAM is also a form of scaling up, not scaling out.

NEW QUESTION # 65
What are the two primary dimensions typically governed by table rate limits in Oracle NoSQL Database Cloud Service?

A. CPU utilization and memory consumption.
B. Number of indexes and query complexity.
C. Storage capacity and network bandwidth.
D. Read throughput and write throughput.

Answer: D

Explanation:
Rate Limiting in NoSQL:
In Oracle NoSQL Database Cloud Service, rate limiting primarily controlsread and write throughput. This means defining themaximum number of read and write operations per secondthat a table can handle.
The goal is toprevent a single table from consuming excessive resources, ensuringfair allocationand system stability.
Why the other options are incorrect:
* A:Storage capacity is managed via quotas, not rate limits.
* C:CPU and memory are related to system resources, not table operations.
* D:Indexing and query complexity are managed differently, often via query optimization.

NEW QUESTION # 66
Which two prerequisites are required before you can provision a MySQL HeatWave DB system?

A. A pre-configured MySQL database dump for initial data loading.
B. A configured OCI Vault with encryption keys for database security.
C. A Virtual Cloud Network (VCN) with appropriately configured subnets.
D. An OCI Compute instance to act as a client for the MySQL DB system.
E. A MySQL Enterprise Edition license.

Answer: C,E

Explanation:
VCN Requirement (B):
AVirtual Cloud Network (VCN)with appropriate subnets is essential to providenetwork connectivity and isolationfor the HeatWave DB system. It ensures secure data flow within the Oracle Cloud Infrastructure.
License Requirement (E):
Since HeatWave is anenterprise feature, it requires aMySQL Enterprise Edition license.Without this license, the HeatWave functionalities cannot be utilized.
Why the other options are incorrect:
* A:Data loading can be performed post-provisioning.
* C:While encryption can be configured, it is not a prerequisite.
* D:An OCI Compute instance may be used as a client but is not mandatory for provisioning.
