Oracle Cloud Database Services 2025 Professional Sample Questions (Q35-Q40):

NEW QUESTION # 35
A critical query running on your HeatWave cluster is experiencing significant performance degradation.
Which tool or service should you use to identify and analyze the specific query causing the bottleneck?

  • A. OCI Network Visualizer for analyzing network latency.
  • B. OCI Bastion for secure access to the query execution environment.
  • C. OCI Events for tracking query start and end times.
  • D. OCI Vault for auditing query execution.
  • E. MySQL Slow Query Log and OCI Logging Analytics.

Answer: E

Explanation:
MySQL Slow Query Log:
TheMySQL Slow Query Logrecords queries that exceed a specified execution time threshold. It is essential for identifyinglong-running queriesthat may be causing performance bottlenecks.
OCI Logging Analytics:
By integrating the slow query log withOCI Logging Analytics, users can visualize query performance patterns, generate alerts, and identify the root cause of slow performance. This combination is powerful for detecting and addressingquery-specific issues.
Why the other options are incorrect:
* A:OCI Vault is used for managing encryption keys, not query performance.
* B:OCI Events track general occurrences, not detailed query performance.
* D:Network latency analysis is useful but not directly related to query analysis.
* E:OCI Bastion provides secure access, not performance analytics.


NEW QUESTION # 36
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. Maintaining the same network security group (NSG) rules as the production database.
  • B. Using the same database version as the production database.
  • C. Scheduling the cloning operation during off-peak hours.
  • D. Ensuring the compute shape of the cloned database is identical to the production database.
  • E. Masking or anonymizing sensitive data in the cloned database.

Answer: E

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 # 37
Which two of the following options are valid statements regarding the management of the operating system on a Base Database Service Virtual Machine DB System?

  • A. Oracle manages the underlying operating system patching and updates, ensuring the system remains secure and compliant.
  • B. Direct SSH access to the underlying VM is restricted, and all OS-level operations must be performed through the Web Console.
  • C. Customers are responsible for the security and maintenance of the operating system, including applying necessary patches and updates.
  • D. Customers have full root access to the underlying operating system of the Virtual Machine DB System, allowing for customization and installation of custom software.
  • E. Customers are responsible for the initial OS installation, but then patching is controlled entirely by Oracle.

Answer: C,D


NEW QUESTION # 38
Which statement accurately describes the patching process for Oracle Grid Infrastructure (GI) and ASM components on a BaseDB VM system when using user-managed patching?

  • A. Patching GI and ASM components is only required when the operating system of the VM is upgraded.
  • B. The DBA must manually download the GI and ASM patch bundles and apply them using the appropriate patching tools.
  • C. GI and ASM patching is fully automated by Oracle Cloud Infrastructure and requires no user intervention.
  • D. GI and ASM patching is integrated with the database patching process and is automatically handled when the database is patched.

Answer: B

Explanation:
B: Manual patching for GI and ASM:
* In auser-managed environment, the DBA is responsible for downloading and applying patches for Grid Infrastructure (GI)andAutomatic Storage Management (ASM).
* These patches are distinct fromdatabase patchesand need to be applied using tools likeopatchorOracle Universal Installer (OUI).
* The process involves:
* Downloading the patch from Oracle Support.
* Staging the patch on the server.
* Applying the patch using the appropriate commands.
Why the other options are incorrect:
* A. Fully automated by OCI:OCI does not automatically patch GI and ASM in user-managed environments.
* C. Integrated with database patching:GI and ASM patching is handled separately.
* D. Required only during OS upgrade:Incorrect, as patching is required independently for security and stability.


NEW QUESTION # 39
You need to implement a backup and recovery strategy for your MySQL HeatWave Database System. What is the recommended method for backing up and restoring your HeatWave cluster?

  • A. Relying solely on MySQL replication to another MySQL instance.
  • B. Manually copying the data files from the HeatWave cluster's storage.
  • C. Using the OCI Object Storage service for storing manual database dumps.
  • D. Utilizing OCI Database backups, which include both the MySQL Database System and the HeatWave cluster.
  • E. Using the MySQL Enterprise Backup tool directly on the HeatWave nodes.

Answer: D

Explanation:
C: Utilizing OCI Database backups:
* Integrated withOracle Cloud Infrastructure (OCI), providing consistent and complete backups.
* Supports both theMySQL Database System and the HeatWave cluster, ensuring data integrity.
* Automates backup scheduling and retention policies.
* Facilitates easy restoration in case of data loss or corruption.
Why the other options are incorrect:
* A. Manual copying:Prone to errors and lacks consistency.
* B. Manual dumps to Object Storage:Labor-intensive and not automated.
* D. MySQL replication:Suitable for high availability, but not a substitute for regular backups.
* E. MySQL Enterprise Backup on nodes:Complex and not designed for HeatWave's distributed environment.
