Oracle Cloud Database Services 2025 Professional Sample Questions (Q99-Q104):

NEW QUESTION # 99
During the provisioning of a Base Database Service (BaseDB) virtual machine (VM), what is the significance of the "Compute Shape" selection?

A. It dictates the availability domain in which the VM will be created.
B. It defines the CPU, memory, and network bandwidth allocated to the VM.
C. It specifies the pre-installed database software version.
D. It determines the maximum number of databases that can be created on the VM.

Answer: B

Explanation:
C: Defines CPU, memory, and network bandwidth:
* TheCompute Shapespecifies the resources allocated to the VM.
* Shapes vary in the number ofOCPUs, amount ofRAM, andnetwork performance.
* Selecting an appropriate shape ensures the database has enough computational power and memory to meet workload demands.
Why the other options are incorrect:
* A. Number of databases:Limited by storage and resource capacity, not the shape itself.
* B. Availability domain:Chosen separately during provisioning.
* D. Pre-installed software version:The shape does not determine the database version.

NEW QUESTION # 100
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. Immediately apply the patch directly to the production database during off-peak hours to minimize potential security vulnerabilities.
B. Apply the patch to a production standby database (if one exists) and then failover to the patched standby.
C. Wait for Oracle Cloud Infrastructure to automatically apply the security patch to all BaseDB VM systems.
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 # 101
While operating a MySQL HeatWave cluster, you need to resize the HeatWave cluster to accommodate an increased workload. Which method is the most efficient and recommended way to scale the HeatWave cluster?

A. Recreating the HeatWave cluster with the desired size.
B. Performing a manual data export and import into a new, larger MySQL Database System.
C. Using the OCI CLI or Console to adjust the HeatWave cluster's shape and node count.
D. Manually altering the innodb_buffer_pool_size and restarting the MySQL server.
E. Modifying the underlying VM shapes of the MySQL Database System.

Answer: C

Explanation:
Scaling HeatWave Efficiently:
TheOCI CLI or Consoleprovides a streamlined way to scale the HeatWave cluster. You can easily change the shape and node countthrough the console without significant downtime. The system handles the necessary data redistribution and configuration updates automatically.
* This method minimizes disruption and is significantly faster than manual reconfiguration.
* OCI's automated scaling ensures that the cluster maintainsoptimal performancethroughout the operation.
Why the other options are incorrect:
* A:Adjusting buffer size affects memory, not cluster size.
* C:Changing VM shapes does not directly affect HeatWave.
* D:Recreating the cluster is inefficient and time-consuming.
* E:Manual export/import introduces downtime and is not efficient for scaling.

NEW QUESTION # 102
When cloning a BaseDB database for development and testing, which of the following considerations is MOST critical to ensure compliance with data privacy regulations?

A. Masking or anonymizing sensitive data in the cloned database.
B. Maintaining the same network security group (NSG) rules as the production database.
C. Ensuring the compute shape of the cloned database is identical to the production database.
D. Scheduling the cloning operation during off-peak hours.
E. Using the same database version as the production database.

Answer: A

Explanation:
B: Masking or anonymizing sensitive data:
* Data privacy regulations (likeGDPR,HIPAA) mandate thatpersonally identifiable information (PII) is protected, even in non-production environments.
* Cloning a database without masking sensitive data could expose confidential information to unauthorized users.
* Techniques include:
* Data masking:Replacing real data with realistic, but non-sensitive values.
* Data anonymization:Irreversibly removing personally identifiable information.
Why the other options are incorrect:
* A. Matching compute shape:Relevant to performance, not privacy.
* C. Using the same database version:Important for compatibility, but not related to data privacy.
* D. Same NSG rules:Important for network security, but does not directly address data exposure.
* E. Off-peak scheduling:Minimizes disruption but does not address data protection.

NEW QUESTION # 103
Which Oracle Cloud Infrastructure (OCI) service is PRIMARILY used to store backups created from a BaseDB database?

A. OCI Data Transfer Service
B. OCI Object Storage
C. OCI File Storage
D. OCI Block Volume
E. OCI Archive Storage

Answer: B

Explanation:
C: OCI Object Storage:
* The primary storage service for database backups within OCI.
* Offers high durability, availability, and scalability.
* Integrated with Oracle's automated backup solutions for BaseDB.
* Suitable for both short-term and long-term storage of database backups.
Why the other options are incorrect:
* A. OCI Block Volume:Used for primary database storage, not long-term backups.
* B. OCI File Storage:Typically used for file system-based workloads, not for database backups.
* D. OCI Archive Storage:Suitable for long-term archival but not the primary backup destination.
* E. OCI Data Transfer Service:Used for bulk data migration into OCI, not for backup storage.
