Oracle Cloud Database Services 2025 Professional Sample Questions (Q97-Q102):
NEW QUESTION # 97
Within the context of Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) virtual machine (VM) provisioning, which action is typically the RESPONSIBILITY of the customer?
- A. Managing the Oracle Grid Infrastructure software stack.
- B. Ensuring the underlying hardware infrastructure remains fault-tolerant.
- C. Maintaining the OCI hypervisor software.
- D. Automatically applying critical security patches to the operating system.
Answer: A
Explanation:
B: Managing the Oracle Grid Infrastructure software stack:
* Customers are responsible for the installation, configuration, and maintenance of the Oracle Grid Infrastructure when using BaseDB VMs.
* This includes managing Oracle Clusterware and Automatic Storage Management (ASM) if applicable.
* Ensuring the Grid Infrastructure's availability and performance is part of customer-managed tasks.
Why the other options are incorrect:
* A. Hardware fault tolerance:Managed by Oracle Cloud Infrastructure.
* C. Hypervisor maintenance:Handled by Oracle as part of the OCI infrastructure.
* D. Security patching:While OCI provides tools, the responsibility for OS patching lies with the customer.
NEW QUESTION # 98
Oracle NoSQL Database Cloud Service utilizes a key-value data model. Which of the following statements accurately describes the fundamental structure of data within this model?
- A. Each data item is uniquely identified by a key, and the associated value can be any data type or structure.
- B. Data is organized into tables with predefined schemas, similar to relational databases.
- C. Data is stored as JSON documents with flexible structures, allowing for nested elements.
- D. Data is structured in a graph format, representing entities as nodes and relationships as edges.
- E. Relationships between data items are explicitly defined through foreign keys and joins.
Answer: A
Explanation:
C: Each data item is uniquely identified by a key, and the associated value can be any data type or structure.
Key-Value Data Model:
* The key-value model is fundamentally based on a simple association between a unique key and its corresponding value.
* The value can be a simple data type (string, number) or a complex structure (like JSON).
* Oracle NoSQL Database Cloud Service uses this model to ensure efficient, scalable data access.
Why the other options are incorrect:
* A. Organized into tables with schemas:This represents a relational database model.
* B. Stored as JSON documents:Although NoSQL can store JSON, the fundamental model is still key- value.
* D. Relationships defined through foreign keys and joins:This is typical of relational databases.
* E. Graph format with nodes and edges:Represents a graph database model, not key-value.
NEW QUESTION # 99
Which of the following statements accurately describes the recommended procedure for patching Grid Infrastructure in a BaseDB VM system where the database is NOT managed by Oracle Cloud Infrastructure (OCI)?
- A. You cannot manually patch Grid Infrastructure in a BaseDB VM system; Oracle Cloud Infrastructure manages all patching operations.
- B. Apply the Grid Infrastructure patch directly to the DB system. OCI handles the patching order for all components automatically.
- C. Apply the Grid Infrastructure patch first, then apply the database patch, after validating the GI is working correctly.
- D. Apply the database patch first, then apply the Grid Infrastructure patch to ensure compatibility.
Answer: C
Explanation:
Recommended Patching Order:
In Oracle environments, it is crucial to patchGrid Infrastructure (GI) firstbecause GI components are responsible formanaging cluster resources and storage. Applying GI patches before database patches ensures that the underlying infrastructure is compatible and stable.
* After the GI patching,validatethe environment to ensure all components are functioningcorrectly before proceeding with database software updates.
* This order minimizes the risk ofdowntime or compatibility issues.
Why the other options are incorrect:
* A:OCI does not automatically handle manual patching in non-managed DB systems.
* B:Applying the database patch first may result in compatibility problems.
* D:Users can manually patch Grid Infrastructure in BaseDB VMs.
NEW QUESTION # 100
Which two statements are true about the Oracle Cloud Infrastructure (OCI) Monitoring tools available for Base Database Service Virtual Machine DB Systems?
- A. DB system performance events are only accessible via the Oracle Database Enterprise Manager interface, and these events cannot be integrated with OCI monitoring tools.
- B. The OCI Monitoring service allows users to define alarms based on metric thresholds, triggering notifications via OCI Notifications service.
- C. Customer-installed monitoring agents are strictly prohibited on Base Database Service Virtual Machine DB Systems to maintain security compliance.
- D. Only Oracle Cloud Agent metrics can be used for metric data charting, alarming, and notifications. OS metrics can only be collected.
- 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: B,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.
NEW QUESTION # 101
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 manage the underlying operating system of the Compute instance.
- B. To automate database patching and upgrades.
- C. To handle database backups and recovery operations.
- 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.
