Oracle Cloud Database Services 2025 Professional Sample Questions (Q33-Q38):

NEW QUESTION # 33
Which two requirements must be met before you can create an Exadata Database Service VM Cluster?

A. A Virtual Cloud Network (VCN) with necessary subnets for client access and backups.
B. A valid support identifier (SI) associated with the OCI account.
C. A configured Oracle Cloud Infrastructure (OCI) Vault and Key.
D. An Exadata Infrastructure resource must be created first.
E. A configured Exadata Cloud@Customer infrastructure.

Answer: A,D

Explanation:
* B. VCN and Subnets:Exadata Database Service VM Clusters require a VCN to provide network connectivity for database instances, client access, and backups. Proper subnets are essential for this network setup.
* E. Exadata Infrastructure Resource:Before creating a VM Cluster, an Exadata Infrastructure resource must be provisioned. The VM Cluster resides within this infrastructure.
Why the other options are incorrect:
* A:OCI Vault and Key are used for encryption but not mandatory for VM Cluster creation.
* C:A valid SI is needed for support but not a technical requirement for VM cluster creation.
* D:Exadata Cloud@Customer is a separate service from Exadata Database Service.

NEW QUESTION # 34
What primary security mechanism within Oracle NoSQL Database Cloud Service governs access to individual tables, dictating which users or groups can perform specific actions?

A. Identity and Access Management (IAM) policies
B. Database Vault
C. Transparent Data Encryption (TDE)
D. Virtual Cloud Network (VCN) security lists

Answer: A

Explanation:
IAM Policies:
Oracle NoSQL Database Cloud Service usesOCI IAM policiesto control access to tables. These policies specify who (user or group) can perform what actions (read, write, delete) on specific database resources. This centralized approach allows for granular permission control, supporting the principle ofleast privilege.
IAM policies are configured at theOCI tenancy leveland can be customized to define access based onusers, groups, and dynamic groups. They are essential for maintaining secure data access, especially in multi- tenant environments.
Why the other options are incorrect:
* A:VCN security lists control network traffic, not table-level access.
* C:Database Vault is for fine-grained access control within traditional Oracle Databases, not NoSQL.
* D:TDE handles data encryption, not access management.

NEW QUESTION # 35
Which statement accurately describes the function of the HeatWave service in relation to a standard MySQL database?

A. HeatWave is a specialized version of MySQL designed solely for transactional workloads, optimized for high concurrency.
B. HeatWave is a standalone database system that replaces MySQL, offering enhanced security features.
C. HeatWave acts as a caching layer in front of MySQL, speeding up access to frequently accessed data.
D. HeatWave is a clustering solution, where a single MySQL instance is split into multiple parts.
E. HeatWave provides an in-memory, massively parallel query accelerator to MySQL, improving analytical query performance.

Answer: E

Explanation:
HeatWave as a Query Accelerator:
HeatWave enhances theMySQL Database Serviceby providing anin-memory, massively parallel query accelerator. It is specifically designed to speed upanalytical (OLAP) queries, making them run significantly faster compared to using MySQL alone.
* The system stores data in acolumnar formatand processes it in memory, utilizingdistributed, parallel processingto achieve high performance.
* Unlike traditional MySQL setups, HeatWave canexecute complex analytical workloadsefficiently.
Why the other options are incorrect:
* A:HeatWave is not a standalone database but an extension of MySQL.
* C:It is optimized foranalytical workloads, not transactional.
* D:It is more than just a caching layer; it actively processes queries.
* E:HeatWave clusters do not split MySQL instances but enhance query processing.

NEW QUESTION # 36
When a new security patch is released for the Oracle Database software on a BaseDB VM system, what is the recommended approach for applying it in a production environment?

A. Wait for Oracle Cloud Infrastructure to automatically apply the security patch to all BaseDB VM systems.
B. Download the patch and apply it to a non-production environment that mirrors the production environment for testing before applying it to production.
C. Apply the patch to a production standby database (if one exists) and then failover to the patched standby.
D. Immediately apply the patch directly to the production database during off-peak hours to minimize potential security vulnerabilities.

Answer: B

Explanation:
B: Testing patches in a non-production environment:
* Critical to ensure that the patch does not introduce performance issues or compatibility problems.
* Best Practice:Apply the patch to astaging environmentthat mirrors production, validate stability, and then proceed to production.
* Minimizes the risk of unplanned downtime or disruptions.
Why the other options are incorrect:
* A. Immediate application in production:Risky as untested patches might cause outages.
* C. Automatic patching by OCI:OCI does not automatically apply database patches; the customer must manage this.
* D. Patching the standby and failing over:While a good strategy when applicable, it still requires prior testing.

NEW QUESTION # 37
Which two statements accurately describe the relationship between Database Management and metrics collected in OCI Monitoring service?

A. Database Management's data collection is completely independent of the OCI Monitoring service.
B. Database Management retrieves performance data exclusively from the OCI Monitoring service and does not directly query the database.
C. Database Management directly queries the database for detailed performance data and supplements it with metrics from the OCI Monitoring service.
D. Database Management relies on custom metrics uploaded to OCI Monitoring by the user in order to provide its monitoring features.

Answer: A,C

Explanation:
B:Database Management directly queries the database to gather performance data, such as SQL performance and active session history. It also integrates with OCI Monitoring for infrastructure-level metrics like CPU, memory, and storage utilization.
C:Database Management can function independently of OCI Monitoring since it has its own data collection mechanisms.
Why the other options are incorrect:
* A:Database Management does not rely solely on OCI Monitoring.
* D:It does not require custom metrics from the user.
