Oracle Cloud Database Services 2025 Professional Sample Questions (Q85-Q90):

NEW QUESTION # 85
What is the primary purpose of installing and configuring the Oracle Management Agent when enabling Database Management Service for a cloud database on a Compute instance?

A. To automate database patching and upgrades.
B. To handle database backups and recovery operations.
C. To manage the underlying operating system of the Compute instance.
D. To provide a secure communication channel between the Database Management Service and the database.

Answer: D

Explanation:
A: Secure Communication Channel:
* The Oracle Management Agent acts as a bridge between theDatabase Management Serviceand the database.
* Enables secure data collection, monitoring, and performance analysis.
* Uses encryption to protect data during transmission.
* Facilitates monitoring, alerting, and management through OCI services.
Why the other options are incorrect:
* B. Backup and recovery operations:These are typically handled by backup tools, not the management agent.
* C. OS management:The agent does not manage the operating system itself.
* D. Patching and upgrades:While it can assist, it is not specifically designed for patch management.

NEW QUESTION # 86
Which two prerequisites are required before you can provision a MySQL HeatWave DB system?

A. A Virtual Cloud Network (VCN) with appropriately configured subnets.
B. A pre-configured MySQL database dump for initial data loading.
C. An OCI Compute instance to act as a client for the MySQL DB system.
D. A configured OCI Vault with encryption keys for database security.
E. A MySQL Enterprise Edition license.

Answer: A,E

Explanation:
VCN Requirement (B):
AVirtual Cloud Network (VCN)with appropriate subnets is essential to providenetwork connectivity and isolationfor the HeatWave DB system. It ensures secure data flow within the Oracle Cloud Infrastructure.
License Requirement (E):
Since HeatWave is anenterprise feature, it requires aMySQL Enterprise Edition license.Without this license, the HeatWave functionalities cannot be utilized.
Why the other options are incorrect:
* A:Data loading can be performed post-provisioning.
* C:While encryption can be configured, it is not a prerequisite.
* D:An OCI Compute instance may be used as a client but is not mandatory for provisioning.

NEW QUESTION # 87
Which statement BEST describes the primary architectural distinction between Exadata Database Service and a traditional Oracle Database deployed on virtual machines in the cloud?

A. Exadata Database Service uses a completely different SQL parsing engine compared to a traditional Oracle Database.
B. Exadata Database Service utilizes only virtualized compute nodes, while traditional deployments use bare metal.
C. Exadata Database Service integrates specialized, high-performance storage servers and a high- bandwidth, low-latency RDMA over Converged Ethernet (RoCE) network, optimized for database workloads, which are not present in typical cloud VM deployments.
D. Exadata Database Service exclusively supports Oracle RAC, while traditional cloud deployments can support both single-instance and RAC databases.

Answer: C

Explanation:
Exadata's Unique Architecture:
Exadata Database Service is engineered specifically for Oracle Database workloads. The architecture leverages specialized storage servers that performdata-intensive operations at the storage level(such as filtering and aggregation), reducing the amount of data sent to the compute nodes.
TheRoCE network(RDMA over Converged Ethernet) provides high-bandwidth, low-latency connectivity between compute and storage nodes, significantly enhancing I/O performance. This architecture is optimized for bothOLTP and OLAP workloads, making Exadata a superior choice for performance-critical applications.
Why the other options are incorrect:
* A:Exadata combines both virtualized and bare metal compute nodes.
* C:Both Exadata and traditional cloud deployments can support Oracle RAC, but Exadata is optimized for it.
* D:Exadata uses the same Oracle Database SQL parsing engine; the difference lies in the optimized hardware.

NEW QUESTION # 88
Which two of the following statements are true regarding security considerations for managingExadata Cloud Infrastructure and VM Clusters?

A. Network Security Groups (NSGs) can be used to control network traffic to and from VM Clusters, enhancing security.
B. Customers have full access to the Exadata Infrastructure's hypervisor and can implement custom security policies.
C. Customers are responsible for configuring host-based firewalls on the Exadata Infrastructure to protect against unauthorized access.
D. Oracle manages all security aspects of the Exadata Infrastructure, relieving customers of any security responsibilities.
E. Customers are responsible for configuring and maintaining the security of the operating system and database software within the VM Clusters.

Answer: A,E

Explanation:
B: Network Security Groups (NSGs) for traffic control:
* NSGs allow customers to defineingress and egress rulesto control network traffic.
* Enhances security by restricting access to only authorized IP ranges and protocols.
* Applied at theVM Clusterlevel to manage connectivity efficiently.
E: Responsibility for OS and database security:
* While Oracle manages the infrastructure layer, customers are responsible for securing theoperating system and databasewithin the VM Clusters.
* This includes applying security patches, configuring firewalls, and implementing user access controls.
Why the other options are incorrect:
* A. Host-based firewalls on Exadata Infrastructure:Oracle, not the customer, configures the infrastructure-level security.
* C. Oracle managing all security:Incorrect, as customers manage VM-level security.
* D. Access to hypervisor:Customers do not have hypervisor-level access for security configuration.

NEW QUESTION # 89
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 Streaming
B. OCI Notifications
C. OCI Monitoring with HeatWave specific metrics
D. OCI Service Connector Hub
E. OCI Functions

Answer: C

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.
