Oracle Cloud Database Services 2025 Professional Sample Questions (Q22-Q27):

NEW QUESTION # 22
Which database lifecycle management operation in BaseDB requires the creation of a new database home and is non-reversible after completion?

  • A. Upgrading the Oracle Grid Infrastructure.
  • B. Applying an operating system patch.
  • C. Enabling Automatic Storage Management (ASM).
  • D. Scaling the compute shape of the VM.
  • E. Upgrading the Oracle Database software version.

Answer: E

Explanation:
Database Software Upgrade:
When upgrading theOracle Database software versionon aBaseDB VM, a newOracle Homeis created to house the upgraded software. Once the database is moved to this new home, the process isnot easily reversible.
* Rolling back would requiredowngrading, which is a complex and risky process.
* The new Oracle Home ensures that the upgraded database environment isisolated from the previous version, preventing compatibility conflicts.
Why the other options are incorrect:
* A:Grid Infrastructure upgrades can be managed independently of the database upgrade.
* B:Scaling VMs is a reversible operation.
* D:OS patches do not impact the Oracle Home directly.
* E:ASM configuration changes are reversible.


NEW QUESTION # 23
If the Database Management Service is failing to collect performance metrics from a cloud database, which is the LEAST likely cause?

  • A. The database user account used by the Management Agent has been locked.
  • B. The database is temporarily offline.
  • C. Incorrect IAM policies preventing the service from accessing the database.
  • D. The Database Management Service instance is located in a different region than the database.

Answer: D

Explanation:
Reasoning:
TheDatabase Management Servicecan collect performance metrics from databases across different regions within the same OCI tenancy. Therefore, the geographic location of the service relative to the database isnot a common issue.
More Likely Causes:
* A:IAM policies that do not grant sufficient permissions are a common issue.
* B:If the database is offline, no metrics can be collected.
* D:A locked database user account used by the Management Agent will prevent data collection.
Why C is incorrect:
The Database Management Service can be configured to collect metrics from databasesacross regions, as long as network access and permissions are properly configured.


NEW QUESTION # 24
Which two functionalities can be accomplished using the Performance Hub within Database Management for monitoring?

  • A. Identify blocking sessions that are impacting database performance.
  • B. Upgrade the database to a newer version.
  • C. Directly modify database initialization parameters.
  • D. Execute ADDM (Automatic Database Diagnostic Monitor) analysis on a historical workload.

Answer: A,D

Explanation:
A: Execute ADDM (Automatic Database Diagnostic Monitor) analysis on a historical workload:
* Performance Hub allows users to analyze performance data collected over time.
* ADDM analysis provides insights into performance bottlenecks and recommendations for tuning.
C: Identify blocking sessions that are impacting database performance:
* Performance Hub helps identify active blocking sessions, enabling quick resolution of performance issues.
* It provides real-time and historical data for better troubleshooting.
Why the other options are incorrect:
* B. Modify database parameters:Performance Hub does not have the ability to change database configurations directly.
* D. Upgrade the database:Upgrades are managed through other tools, such as Database Upgrade Assistant (DBUA).


NEW QUESTION # 25
When considering autoscaling for provisioned throughput in NoSQL Database Cloud Service, which metric is LEAST relevant for determining when to scale up the capacity units?

  • A. Number of rejected read requests due to insufficient RCUs.
  • B. Latency of read and write operations.
  • C. Number of rejected write requests due to insufficient WCUs.
  • D. CPU utilization of the compute instances hosting the database.

Answer: D

Explanation:
A: CPU utilization of the compute instances hosting the database:
* Autoscaling in NoSQL Database Cloud Service primarily focuses onRCUs (Read Capacity Units)and WCUs (Write Capacity Units).
* The objective is to dynamically adjust capacity based onquery workload, not onCPU utilization.
* Even if CPU usage is high, it might not necessarily indicate that the capacity units are inadequate.
Why the other options are more relevant:
* B. Rejected read requests (RCUs):Direct indicator that read capacity is insufficient, requiring scaling.
* C. Rejected write requests (WCUs):Indicates that the write throughput is inadequate, necessitating scaling.
* D. Latency of read and write operations:Increased latency often points to under-provisioned throughput.


NEW QUESTION # 26
When migrating to MySQL HeatWave on Oracle Cloud Infrastructure (OCI), what is the recommended method for securely transferring large database backups?

  • A. Transferring the backup files directly over the public internet using FTP.
  • B. Creating a secure VPN connection and transferring the backup files using scp.
  • C. Use of Data Pump with a database link.
  • D. Using the Oracle Cloud Infrastructure Data Transfer Service with physical storage appliances.
  • E. Shipping physical hard drives containing the backup files to the OCI data center.

Answer: D

Explanation:
Secure Transfer with OCI Data Transfer Service:
TheOCI Data Transfer Serviceis designed to securely transfer large datasets, including database backups, to the cloud. It involves:
* Using physical storage appliancesto copy data locally and then shipping these devices to OCI data centers.
* Data isencrypted and securely transported, minimizing the risks associated with online transfers.
* This method is cost-effective and practical forterabytes or petabytes of data, avoiding bandwidth limitations and reducing transfer time.
Why the other options are incorrect:
* A:FTP over the public internet is insecure and slow.
* B:Physical hard drives without encryption and secure handling increase data breach risks.
* D:SCP over VPN is secure but impractical for extremely large datasets.
* E:Data Pump is useful for database-to-database transfers, not large file migrations.
