Oracle Cloud Database Services 2025 Professional Sample Questions (Q74-Q79):

NEW QUESTION # 74
Which two are valid mechanisms for accessing OS-level metrics on a Base Database Service Virtual Machine?

A. Utilize the vmcli utility, which allows access to OS-level metrics specific to the DB System.
B. Access OS metrics programmatically via the OCI Monitoring APIs, which allow retrieval of metrics collected by the Oracle Cloud Agent.
C. All OS metrics are automatically pushed to the Cloud Exadata Service Dashboard, and are not available outside of this service.
D. Access OS metrics using the OCI Metrics Explorer within the OCI Console leveraging the Oracle Cloud Agent.
E. The only way to access OS-level metrics is through a custom monitoring agent installed directly on the VM.

Answer: B,D

Explanation:
B: Access OS metrics using the OCI Metrics Explorer within the OCI Console leveraging the Oracle Cloud Agent.
* OCI Metrics Explorer is part of the OCI Monitoring service.
* The Oracle Cloud Agent collects OS-level metrics and makes them available through the OCI Console.
* Users can view metrics like CPU usage, memory utilization, and disk I/O.
E: Access OS metrics programmatically via the OCI Monitoring APIs:
* The Oracle Cloud Agent collects OS metrics and exposes them via OCI Monitoring APIs.
* This approach allows for automated data retrieval and integration with external monitoring tools.
Why the other options are incorrect:
* A. vmcli utility:This is not a standard tool for accessing OS-level metrics on Base Database Service VMs.
* C. Custom monitoring agent:While possible, it is not the primary or only method. Oracle Cloud Agent is the default tool.
* D. Automatically pushed to the Cloud Exadata Service Dashboard:This statement is incorrect as OS metrics are available through OCI Monitoring.

NEW QUESTION # 75
Which BaseDB lifecycle management activity is MOST directly associated with ensuring the continued availability of a database instance during a planned maintenance window?

A. Performing an in-place upgrade of the database software.
B. Taking a full database backup using RMAN.
C. Resizing the block volume storage.
D. Applying a quarterly security patch.
E. Using Oracle Data Guard for a switchover operation.

Answer: E

Explanation:
C: Using Oracle Data Guard for a switchover operation:
* Aswitchoveris a planned role reversal between the primary and standby databases.
* Zero data loss:Since both databases are synchronized, it minimizes downtime.
* Ideal for planned maintenance:The primary database is switched to the standby, allowing maintenance on the original primary without downtime.
* Data Guard Switchover:
sql
CopyEdit
ALTER DATABASE SWITCHOVER TO standby_db;
Why the other options are incorrect:
* A. Full backup with RMAN:Backup does not ensure availability during maintenance.
* B. In-place upgrade:Typically involves downtime.
* D. Quarterly patch:Patching often requires database restarts, causing downtime.
* E. Resizing block volume:Does not maintain availability if the database requires restarting.

NEW QUESTION # 76
Which Oracle Cloud Infrastructure (OCI) service is PRIMARILY used to store backups created from a BaseDB database?

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

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.

NEW QUESTION # 77
How does the HeatWave Lakehouse capability extend the analytical capabilities of MySQL HeatWave?

A. By automatically replicating the MySQL database to a disaster recovery site.
B. By providing a graphical user interface for managing the MySQL database.
C. By providing a built-in ETL (Extract, Transform, Load) tool for data integration.
D. By creating a separate data warehouse in the cloud to store historical data.
E. By enabling HeatWave to query data directly from object storage (e.g., Oracle Cloud Infrastructure Object Storage, Amazon S3) in various formats without requiring data loading.

Answer: E

Explanation:
B: Querying data directly from object storage without data loading:
* HeatWave Lakehouse extends MySQL HeatWave by allowing direct query execution on data stored in external object storage.
* Supports formats such asCSV,Parquet, andAvro.
* Eliminates the need for data import, making the process faster and more efficient for large datasets.
* Enhances HeatWave's capability to act as aLakehouseby unifying data warehousing and data lake functionalities.
Why the other options are incorrect:
* A. GUI for database management:Not related to analytical extension.
* C. Disaster recovery replication:Not related to Lakehouse functionality.
* D. Built-in ETL tool:Lakehouse focuses on query capability, not ETL.
* E. Separate data warehouse:HeatWave Lakehouse queries data in-place, not creating a separate warehouse.

NEW QUESTION # 78
You need to monitor the data loading process into your HeatWave cluster to ensure optimal performance.
Which OCI service provides the most detailed information on data loading operations and potential bottlenecks?

A. OCI Notifications
B. OCI Streaming
C. OCI Functions
D. OCI Monitoring with HeatWave specific metrics
E. OCI Service Connector Hub

Answer: D

Explanation:
C: OCI Monitoring with HeatWave specific metrics:
* OCI Monitoring collects and visualizes detailed metrics related to HeatWave cluster operations.
* Key metrics include:
* Data load throughput
* Data load latency
* Memory and CPU utilization
* These metrics help identify bottlenecks during data loading, allowing for proactive performance tuning.
* Integrates withOCI Alarmsto notify administrators when thresholds are breached.
Why the other options are incorrect:
* A. OCI Notifications:Sends alerts but does not collect performance metrics.
* B. OCI Service Connector Hub:Moves data between services but does not provide direct performance insights.
* D. OCI Streaming:Used for real-time data ingestion, not specifically for HeatWave monitoring.
* E. OCI Functions:Executes serverless functions, not related to HeatWave metrics.
