Oracle Cloud Database Services 2025 Professional Sample Questions (Q28-Q33):

NEW QUESTION # 28
Within an IAM policy for Oracle NoSQL Database Cloud Service, what is the purpose of the "resource" element when defining table access permissions?

A. To set the expiration date for the IAM policy.
B. To specify the IAM group that the policy applies to.
C. To define the specific NoSQL table or tables to which the policy's permissions apply.
D. To determine the geographical region where the NoSQL database is located.

Answer: C

Explanation:
B: Define specific NoSQL table permissions:
* The"resource"element specifies which Oracle NoSQL tables the IAM policy will apply to.
* It allows fine-grained access control by linking specific tables to permission statements.
* This ensures that only authorized users or groups can perform operations on specified tables.
Example IAM Policy Syntax:
{
"action": "nosql:table:read",
"resource": "ocid1.nosqltable.oc1..exampleuniqueID",
"effect": "allow"
}
Why the other options are incorrect:
* A. Specify IAM group:Groups are defined in the"subject"element, not the "resource" element.
* C. Geographical region:The region is usually part of theOCID(Oracle Cloud Identifier), not directly specified in the resource element.
* D. Set expiration date:Expiry is not defined within the "resource" element.

NEW QUESTION # 29
During the provisioning of a Base Database Service (BaseDB) virtual machine (VM), what is the significance of the "Compute Shape" selection?

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

Answer: A

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 # 30
Which technology within the Exadata Database Service provides intelligent data offloading and processing capabilities directly within the storage tier?

A. Oracle Data Guard
B. Oracle Active Data Guard
C. Exadata Smart Flash Cache
D. Exadata Smart Scan

Answer: D

Explanation:
Exadata Smart Scan:
This technology is a core feature of Exadata storage servers. It allows the storage servers to perform data filtering, projection, and other processing tasks directly within the storage tier before sending the results to the database compute nodes. This significantly reduces the amount of data transferred over the network, leading to improved query performance.
Why the other options are incorrect:
* A. Oracle Data Guard:Used for disaster recovery and high availability, not for in-storage processing.
* C. Oracle Active Data Guard:Allows read-only access to a standby database, but doesn't provide in- storage processing.
* D. Exadata Smart Flash Cache:Used for caching frequently accessed data in flash memory to improve I/O performance. While it enhances performance, it does not provide intelligent data offloading and processing within the storage tier.

NEW QUESTION # 31
Which of the following components is responsible for automatically offloading suitable queries from MySQL to the HeatWave accelerator?

A. MySQL Shell
B. Oracle Cloud Infrastructure (OCI) Load Balancer
C. MySQL Router
D. MySQL Query Optimizer
E. HeatWave AutoPilot

Answer: D

Explanation:
A: MySQL Query Optimizer:
* TheMySQL Query Optimizerdetermines whether a query can benefit from HeatWave's in-memory, columnar processing.
* If a query is deemed suitable, it is automatically offloaded to the HeatWave cluster.
* This process significantly improves the execution speed of complex analytical queries.
Why the other options are incorrect:
* B. HeatWave AutoPilot:Manages workload optimization but does not directly offload queries.
* C. MySQL Router:Manages connection routing, not query offloading.
* D. MySQL Shell:Primarily used for administrative tasks, not query optimization.
* E. OCI Load Balancer:Manages network traffic distribution, unrelated to database query processing.

NEW QUESTION # 32
Which two statements are true about the Oracle Cloud Infrastructure (OCI) Monitoring tools available for Base Database Service Virtual Machine DB Systems?

A. The OCI Monitoring service allows users to define alarms based on metric thresholds, triggering notifications via OCI Notifications service.
B. Customer-installed monitoring agents are strictly prohibited on Base Database Service Virtual Machine DB Systems to maintain security compliance.
C. Only Oracle Cloud Agent metrics can be used for metric data charting, alarming, and notifications. OS metrics can only be collected.
D. DB system performance events are only accessible via the Oracle Database Enterprise Manager interface, and these events cannot be integrated with OCI monitoring tools.
E. Oracle Cloud Agent collects OS, VM, and Database metrics, which are reported to the OCI Monitoring service and can be visualized via charts or dashboards.

Answer: A,E

Explanation:
Oracle Cloud Agent Capabilities (C):
The Oracle Cloud Agent collects a wide range of metrics, includingOS-level, VM, and database performance metrics. These metrics are integrated with theOCI Monitoring service, where users can view them in customizable charts and dashboards.
Alarms and Notifications (D):
The OCI Monitoring service enables users to set alarms that trigger when certain thresholds are exceeded.
Notifications are sent via theOCI Notifications service, providing proactive monitoring and alerting.
Why the other options are incorrect:
* A:Users can use custom metrics alongside Oracle Cloud Agent metrics.
* B:Customers are allowed to install additional monitoring agents if needed.
* E:Performance data can be integrated with OCI monitoring tools, not limited to Enterprise Manager.
