Oracle Cloud Database Services 2025 Professional Sample Questions (Q56-Q61):

NEW QUESTION # 56
Which two actions must you undertake when configuring the networking to provide network connectivity for a MySQL HeatWave DB System instance?

A. Deploy the MySQL HeatWave DB System to a public subnet to allow external connectivity for users.
B. Configure a dynamic routing gateway for inter-VCN connectivity.
C. Create ingress security rules in the VCN security list or Network Security Groups (NSGs) to allow traffic to the MySQL HeatWave DB System.
D. Ensure the subnet used has a Service Gateway to Oracle Services, such as Object Storage, so that patching can be applied.
E. Create egress security rules in the VCN security list or Network Security Groups (NSGs) to block access from the MySQL HeatWave DB System to any outside network.

Answer: C,D

Explanation:
A: Service Gateway for Oracle Services:
* Ensures the HeatWave DB System can accessOracle Serviceslike Object Storage without using the public internet.
* Essential for tasks such aspatching and backups.
C: Ingress security rules:
* Allows necessary traffic to reach the HeatWave DB System.
* Typically, rules will permitMySQL port (3306)and anyapplication-specific ports.
* Configured usingVCN security lists or NSGs.
Why the other options are incorrect:
* B. Public subnet deployment:Exposes the database to the internet, which is a security risk.
* D. Dynamic routing gateway:Not mandatory unless inter-VCN connectivity is specifically required.
* E. Blocking egress entirely:Restricting all outbound traffic can prevent necessary updates and communication with Oracle services.

NEW QUESTION # 57
In the context of MySQL HeatWave, what is the purpose of the HeatWave AutoPilot feature?

A. To automatically generate reports on MySQL performance and usage.
B. To automatically back up and restore the MySQL database to Oracle Cloud Infrastructure Object Storage.
C. To automatically detect and prevent security vulnerabilities in the MySQL database.
D. To automate various aspects of HeatWave management, such as data placement, node sizing and resource allocation, and query scheduling.
E. To automatically scale the number of MySQL instances based on transactional workload demands.

Answer: D

Explanation:
C: To automate various aspects of HeatWave management, such as data placement, node sizing and resource allocation, and query scheduling.
HeatWave AutoPilot Automation:
* HeatWave AutoPilot is designed to simplify and optimize the management of HeatWave.
* It automates critical tasks like:
* Data placement:Optimizing where data is stored in the HeatWave cluster for efficient query processing.
* Node sizing and resource allocation:Dynamically adjusting the size of the HeatWave cluster and allocating resources based on workload demands.
* Query scheduling:Optimizing the execution of queries for maximum performance.
* Enhanced Performance:By automating these tasks, HeatWave AutoPilot helps to ensure optimal performance and resource utilization.
Why the other options are incorrect:
* A. Automatically detecting and preventing security vulnerabilities:This is not the primary function of HeatWave AutoPilot.
* B. Automatically scaling MySQL instances based on transactional workload:HeatWave is focused on analytical workloads, not transactional scaling.
* D. Automatically generating performance reports:While monitoring is important, this isnot the main purpose of AutoPilot.
* E. Automatically backing up to OCI Object Storage:Backup and restore are separate functions and not part of AutoPilot's core functionality.

NEW QUESTION # 58
Which two requirements must be met first to create an Exadata Database Service Instance?

A. You only need a VCN and Universal Cloud Credits.
B. There are no prerequisites for creating an Exadata Database Service instance.
C. You need to define the VCN, Private Client subnet, and Private Backup subnet.
D. You need to create an Exadata Infrastructure and VM Cluster resource.
E. You need to define the VCN, Private Client subnet, and Service Backup subnet.

Answer: C,D

Explanation:
C: Define VCN, Private Client subnet, and Private Backup subnet:
* These network components are necessary to ensure secure connectivity and backup configurations.
* TheVCN (Virtual Cloud Network)provides network isolation.
* ThePrivate Client subnetenables secure client connections.
* ThePrivate Backup subnetis required for secure access toOCI Object Storagefor backups.
E: Create Exadata Infrastructure and VM Cluster resource:
* Exadata Infrastructure represents the physical hardware.
* VM Cluster resource defines compute and storage resources for the databases.
* Both must be set up before provisioning the actual database instance.
Why the other options are incorrect:
* A. VCN and Universal Cloud Credits:Insufficient; more configuration is needed.
* B. Service Backup subnet:Incorrect, it should be aPrivate Backup subnet.
* D. No prerequisites:Incorrect; prerequisites include both network and infrastructure setup.

NEW QUESTION # 59
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. Maintaining the OCI hypervisor software.
B. Ensuring the underlying hardware infrastructure remains fault-tolerant.
C. Managing the Oracle Grid Infrastructure software stack.
D. Automatically applying critical security patches to the operating system.

Answer: C

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 # 60
You need to implement a backup and recovery strategy for your MySQL HeatWave Database System. What is the recommended method for backing up and restoring your HeatWave cluster?

A. Using the MySQL Enterprise Backup tool directly on the HeatWave nodes.
B. Using the OCI Object Storage service for storing manual database dumps.
C. Relying solely on MySQL replication to another MySQL instance.
D. Utilizing OCI Database backups, which include both the MySQL Database System and the HeatWave cluster.
E. Manually copying the data files from the HeatWave cluster's storage.

Answer: D

Explanation:
C: Utilizing OCI Database backups:
* Integrated withOracle Cloud Infrastructure (OCI), providing consistent and complete backups.
* Supports both theMySQL Database System and the HeatWave cluster, ensuring data integrity.
* Automates backup scheduling and retention policies.
* Facilitates easy restoration in case of data loss or corruption.
Why the other options are incorrect:
* A. Manual copying:Prone to errors and lacks consistency.
* B. Manual dumps to Object Storage:Labor-intensive and not automated.
* D. MySQL replication:Suitable for high availability, but not a substitute for regular backups.
* E. MySQL Enterprise Backup on nodes:Complex and not designed for HeatWave's distributed environment.
