Oracle Cloud Database Services 2025 Professional Sample Questions (Q60-Q65):

NEW QUESTION # 60
If the provisioned read capacity units (RCUs) are consistently underutilized for a NoSQL Database Cloud Service table, what is the MOST direct consequence?

A. Improved query performance.
B. Reduced data durability.
C. Increased storage efficiency.
D. Unnecessary cost expenditure.

Answer: D

Explanation:
C: Unnecessary cost expenditure:
* In Oracle NoSQL Database Cloud Service, you pay for the provisioned RCUs regardless of actual usage.
* Consistently underutilized RCUs mean that you are incurring costs without fully utilizing the allocated resources.
* Proper capacity planning is crucial to optimize costs.
* To reduce expenses, monitor utilization and adjust RCUs accordingly.
Why the other options are incorrect:
* A. Improved query performance:While having adequate RCUs prevents throttling, over-provisioning does not inherently enhance performance.
* B. Increased storage efficiency:Storage is independent of RCUs, which relate to read throughput.
* D. Reduced data durability:Durability is not impacted by underutilized read capacity.

NEW QUESTION # 61
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 facilitates comparing parameter settings between different databases or across different points in time for a single database.
D. Database Management can automatically detect and correct parameter settings that deviate fromOracle- recommended best practices, regardless of the database edition.

Answer: A,C

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 # 62
When migrating a MySQL instance to MySQL HeatWave, which method generally provides the MINIMAL downtime for large databases?

A. Using a third-party ETL tool to extract, transform, and load the data into the HeatWave instance.
B. Creating a physical backup using MySQL Enterprise Backup and restoring it to the HeatWave instance.
C. Utilizing MySQL replication to replicate data to the HeatWave instance and then performing a switchover.
D. Copying the data files directly from the source instance to the HeatWave instance.
E. Using mysqldump to create a logical backup and restoring it to the HeatWave instance.

Answer: C

Explanation:
Using MySQL Replication for Minimal Downtime:
Replication allows forreal-time synchronizationbetween the source MySQL instance and theHeatWave instance. Once the replication catches up, performing aswitchoverto the HeatWave instance ensures minimal disruption.
* This method is especially effective forlarge databases, as data is continuouslysynchronized during the migration process.
* The switchover itself incurs minimal downtime as the applications are redirected to the new instance.
Why the other options are incorrect:
* A:mysqldump and restore are time-consuming for large datasets.
* B:Physical backup and restore are faster than logical, but still involve significant downtime.
* D:Direct data file copying is risky and may cause data corruption.
* E:ETL processes are typically slow and prone to data consistency issues.

NEW QUESTION # 63
Which technology within the Exadata Database Service provides intelligent data offloading and processing capabilities directly within the storage tier?

A. Exadata Smart Scan
B. Exadata Smart Flash Cache
C. Oracle Data Guard
D. Oracle Active Data Guard

Answer: A

Explanation:
Exadata Smart Scan:
This technology is a core feature of Exadata storage servers. It allows the storage servers to perform data filtering, projection, and other processing tasks directly within the storage tier before sending the results to the database compute nodes. This significantly reduces the amount of data transferred over the network, leading to improved query performance.
Why the other options are incorrect:
* A. Oracle Data Guard:Used for disaster recovery and high availability, not for in-storage processing.
* C. Oracle Active Data Guard:Allows read-only access to a standby database, but doesn't provide in- storage processing.
* D. Exadata Smart Flash Cache:Used for caching frequently accessed data in flash memory to improve I/O performance. While it enhances performance, it does not provide intelligent data offloading and processing within the storage tier.

NEW QUESTION # 64
Which two statements accurately describe the relationship between Database Management and metrics collected in OCI Monitoring service?

A. Database Management relies on custom metrics uploaded to OCI Monitoring by the user in order to provide its monitoring features.
B. Database Management directly queries the database for detailed performance data and supplements it with metrics from the OCI Monitoring service.
C. Database Management retrieves performance data exclusively from the OCI Monitoring service and does not directly query the database.
D. Database Management's data collection is completely independent of the OCI Monitoring service.

Answer: B,D

Explanation:
B:Database Management directly queries the database to gather performance data, such as SQL performance and active session history. It also integrates with OCI Monitoring for infrastructure-level metrics like CPU, memory, and storage utilization.
C:Database Management can function independently of OCI Monitoring since it has its own data collection mechanisms.
Why the other options are incorrect:
* A:Database Management does not rely solely on OCI Monitoring.
* D:It does not require custom metrics from the user.
