Answer : A, B

A: Data disk group encryption using OCI Vault provides enhanced security for sensitive data by encrypting data stored within the Exadata storage cells.

B: During provisioning, the size of the DATA and RECO disk groups must be specified. The DATA disk group is used for primary database files, while the RECO disk group is used for recovery-related files.

Why the other options are incorrect:

C: CPU count is part of the compute configuration, not storage.

D: Compression and deduplication settings are managed at the database level, not during storage configuration.

E: Database name and version are part of the database configuration, not storage settings.

Oracle Exadata Storage Configuration

Answer : A, E

A: Exadata VM Clusters can be managed independently from the Exadata Infrastructure. This means you can start or stop the cluster without affecting the infrastructure, which provides flexibility for maintenance and performance tuning.

E: The VM Cluster can be terminated without impacting the Exadata Infrastructure. This feature is useful when you want to reassign the infrastructure resources to a new or different cluster.

Why the other options are incorrect:

B: While some adjustments might not need a reboot, core count scaling often requires restarting.

C: Patching the infrastructure and the VM Cluster are separate processes.

D: Changing the infrastructure shape does not automatically adjust VM Cluster resources. Manual reconfiguration is needed.

Answer : B

AutoML in MySQL HeatWave:

The AutoML feature in MySQL HeatWave integrates machine learning capabilities directly within the database, allowing users to:

Build, train, and deploy models without moving data to external systems.

Automate the entire ML pipeline, including data preprocessing, model selection, and hyperparameter tuning.

This makes it easier for data engineers and analysts to perform predictive analytics without requiring data science expertise.

Why the other options are incorrect:

A: AutoML does not focus on server tuning; it focuses on machine learning.

C: Generating SQL queries from natural language is not within AutoML's scope.

D: AutoML is unrelated to database backup.

E: Visualization is not the primary function; it focuses on model building.

Answer : B

Scaling HeatWave Efficiently:

The OCI CLI or Console provides a streamlined way to scale the HeatWave cluster. You can easily change the shape and node count through the console without significant downtime. The system handles the necessary data redistribution and configuration updates automatically.

This method minimizes disruption and is significantly faster than manual reconfiguration.

OCI's automated scaling ensures that the cluster maintains optimal performance throughout the operation.

Why the other options are incorrect:

A: Adjusting buffer size affects memory, not cluster size.

C: Changing VM shapes does not directly affect HeatWave.

D: Recreating the cluster is inefficient and time-consuming.

E: Manual export/import introduces downtime and is not efficient for scaling.

Answer : A, C

A . Service Gateway for Oracle Services:

Ensures the HeatWave DB System can access Oracle Services like Object Storage without using the public internet.

Essential for tasks such as patching and backups.

C . Ingress security rules:

Allows necessary traffic to reach the HeatWave DB System.

Typically, rules will permit MySQL port (3306) and any application-specific ports.

Configured using VCN 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.
