Oracle Cloud Database Services 2025 Professional Sample Questions (Q52-Q57):

NEW QUESTION # 52
What are the two primary dimensions typically governed by table rate limits in Oracle NoSQL Database Cloud Service?

A. CPU utilization and memory consumption.
B. Number of indexes and query complexity.
C. Read throughput and write throughput.
D. Storage capacity and network bandwidth.

Answer: C

Explanation:
Rate Limiting in NoSQL:
In Oracle NoSQL Database Cloud Service, rate limiting primarily controlsread and write throughput. This means defining themaximum number of read and write operations per secondthat a table can handle.
The goal is toprevent a single table from consuming excessive resources, ensuringfair allocationand system stability.
Why the other options are incorrect:
* A:Storage capacity is managed via quotas, not rate limits.
* C:CPU and memory are related to system resources, not table operations.
* D:Indexing and query complexity are managed differently, often via query optimization.

NEW QUESTION # 53
When migrating a MySQL instance to MySQL HeatWave, which method generally provides the MINIMAL downtime for large databases?

A. Creating a physical backup using MySQL Enterprise Backup and restoring it to the HeatWave instance.
B. Using a third-party ETL tool to extract, transform, and load the data into the HeatWave instance.
C. Copying the data files directly from the source instance to the HeatWave instance.
D. Utilizing MySQL replication to replicate data to the HeatWave instance and then performing a switchover.
E. Using mysqldump to create a logical backup and restoring it to the HeatWave instance.

Answer: D

Explanation:
Using MySQL Replication for Minimal Downtime:
Replication allows forreal-time synchronizationbetween the source MySQL instance and theHeatWave instance. Once the replication catches up, performing aswitchoverto the HeatWave instance ensures minimal disruption.
* This method is especially effective forlarge databases, as data is continuouslysynchronized during the migration process.
* The switchover itself incurs minimal downtime as the applications are redirected to the new instance.
Why the other options are incorrect:
* A:mysqldump and restore are time-consuming for large datasets.
* B:Physical backup and restore are faster than logical, but still involve significant downtime.
* D:Direct data file copying is risky and may cause data corruption.
* E:ETL processes are typically slow and prone to data consistency issues.

NEW QUESTION # 54
Which two prerequisites are required before you can provision a MySQL HeatWave DB system?

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

Answer: A,C

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 # 55
Which of the following is a TRUE statement regarding the storage options typically available when launching an Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) virtual machine (VM)?

A. Object Storage is the default storage option for database datafiles.
B. File Storage is mandatory for database backups.
C. Local NVMe storage is always the default for BaseDB.
D. Block Volumes provide the primary storage and are directly attached to the VM.

Answer: D

Explanation:
A: Block Volumes provide the primary storage and are directly attached to the VM.
Block Volumes:
* These are persistent, durable block storage volumes that are attached to the VM instance.
* Used to store database datafiles, redo logs, and other database-related files.
* Standard and most common way to provision storage for BaseDB VMs.
Why the other options are incorrect:
* B. Object Storage as the default for database datafiles:Object Storage is used for backups and unstructured data, not the primary database files.
* C. Local NVMe as the default:Local NVMe provides high performance but is not always the default.
Block Volumes are standard.
* D. File Storage is mandatory for backups:Not mandatory. Block Volumes or Object Storage can also be used.

NEW QUESTION # 56
In the context of MySQL HeatWave, what is the purpose of the HeatWave AutoPilot feature?

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

Answer: C

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.
