Oracle Cloud Database Services 2025 Professional Sample Questions (Q78-Q83):

NEW QUESTION # 78
Which two statements accurately describe the Database Management's Autonomous Database monitoring capability?

A. Database Management does not support monitoring Autonomous Databases without enabling advanced features in the Autonomous Database itself.
B. Database Management can monitor Autonomous Databases, however, the retention period for performance data is shorter compared to that of non-Autonomous Databases.
C. Database Management provides real-time and historical performance data, but is limited to monitoring CPU utilization on Autonomous Databases.
D. Database Management offers comprehensive performance monitoring for Autonomous Databases, including CPU utilization, I/O statistics, active session history, and SQL performance analysis.

Answer: B,D

Explanation:
Comprehensive Monitoring (C):
Database Management supportsdetailed performance monitoringfor Autonomous Databases, including metrics likeCPU usage, I/O statistics, and SQL performance data.
Data Retention Limitation (D):
Theretention period for performance dataon Autonomous Databases is typically shorter than that of manually managed databases due toautomated data management policies.
Why the other options are incorrect:
* A:Database Management covers more than just CPU monitoring.
* B:Monitoring does not require enabling additional features on the Autonomous Database.

NEW QUESTION # 79
When migrating to MySQL HeatWave on Oracle Cloud Infrastructure (OCI), what is the recommended method for securely transferring large database backups?

A. Shipping physical hard drives containing the backup files to the OCI data center.
B. Transferring the backup files directly over the public internet using FTP.
C. Using the Oracle Cloud Infrastructure Data Transfer Service with physical storage appliances.
D. Creating a secure VPN connection and transferring the backup files using scp.
E. Use of Data Pump with a database link.

Answer: C

Explanation:
Secure Transfer with OCI Data Transfer Service:
TheOCI Data Transfer Serviceis designed to securely transfer large datasets, including database backups, to the cloud. It involves:
* Using physical storage appliancesto copy data locally and then shipping these devices to OCI data centers.
* Data isencrypted and securely transported, minimizing the risks associated with online transfers.
* This method is cost-effective and practical forterabytes or petabytes of data, avoiding bandwidth limitations and reducing transfer time.
Why the other options are incorrect:
* A:FTP over the public internet is insecure and slow.
* B:Physical hard drives without encryption and secure handling increase data breach risks.
* D:SCP over VPN is secure but impractical for extremely large datasets.
* E:Data Pump is useful for database-to-database transfers, not large file migrations.

NEW QUESTION # 80
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 scale the number of MySQL instances based on transactional workload demands.
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 back up and restore the MySQL database to Oracle Cloud Infrastructure Object Storage.

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 # 81
Which two requirements must be met first to create an Exadata Database Service Instance?

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

Answer: B,C

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 # 82
Which of the following characteristics is most indicative of a NoSQL database's focus on scalability and availability over strict consistency?

A. Enforcement of strict referential integrity constraints.
B. Partitioning and replication of data across multiple nodes.
C. Reliance on a centralized, single-instance architecture.
D. Support for complex joins and transactions across multiple tables.

Answer: B

Explanation:
C: Partitioning and replication of data across multiple nodes:
* NoSQL databases typically prioritizehorizontal scalabilityby distributing data across multiple nodes.
* Replicationensures data availability even if one node fails.
* This approach leads toeventual consistencyrather than strict ACID compliance.
* The system can continue to operate despite some nodes being offline, maintaining high availability.
Why the other options are incorrect:
* A. Complex joins and transactions:Typical of relational databases prioritizing consistency.
* B. Strict referential integrity:More common in SQL databases requiring ACID transactions.
* D. Centralized architecture:Opposite of scalable, distributed NoSQL models.
