B. HeatWave leverages a distributed caching mechanism to store frequently accessed data.

C. HeatWave employs a columnar data format in memory, enabling faster scans and aggregations for complex queries.

D. HeatWave uses a specialized indexing technique to speed up data retrieval.

E. HeatWave automatically shards the database to distribute the workload across multiple nodes.

A. The necessary IAM policies must be in place to grant the Database Management Service access to the database.

B. The Oracle Management Agent must be installed and running on the database host, if applicable.

C. The database must be configured with automatic backups enabled.

D. The database must be running and accessible.

A. Each VM Cluster must be associated with its own dedicated VCN, isolating network traffic between clusters.

B. Multiple VM Clusters can be created within a single Exadata Cloud Infrastructure, allowing for workload isolation.

C. Only one VM Cluster can exist within an Exadata Cloud Infrastructure.

D. VM Clusters can span multiple Exadata Cloud Infrastructures, providing a single, unified database environment.

E. VM Clusters within the same Exadata Infrastructure can share a single VCN, simplifying network management.

A. To prevent a single table from consuming excessive resources, ensuring fair allocation and preventing performance degradation for other tables and users.

B. To restrict the total amount of storage space a table can consume.

C. To automatically optimize table schema design for improved query performance.

D. To enforce strict data consistency across all table partitions, ensuring ACID compliance.

A. Direct control over the operating system and database configuration.

B. Automatic scaling of compute and storage resources based on workload demands.

C. Shared Exadata infrastructure with other tenants for cost optimization.

D. Automated patching and upgrades handled by Oracle.

A. Analyze the execution plan of a SQL statement and suggest alternative indexing strategies.

B. Generate a report highlighting the performance impact of a specific database change on a set of SQL statements.

C. Automatically rewrite SQL queries to improve their performance.

D. Compare the performance of SQL statements before and after a database change (e.g., upgrade, parameter change).

A. A write-heavy workload typically necessitates more write capacity units than a read-heavy workload.

B. Higher query complexity generally requires higher read throughput.

C. Larger average record sizes usually demand higher read and write capacity units.

D. Increased frequency of table scans reduces the throughput needed.

A. MySQL Slow Query Log and OCI Logging Analytics.

B. OCI Bastion for secure access to the query execution environment.

C. OCI Vault for auditing query execution.
