Q62. Which statement accurately reflects the impact of applying an Oracle-provided patch to the operating system on an Exadata Database Service instance using the Oracle Cloud Infrastructure (OCI) console?

The OCI console-initiated patch process only updates the database software, leaving the underlying OS untouched.

The OCI console-initiated patch process automatically updates both the database software and the underlying operating system on all compute and storage nodes concurrently.

The OCI console-initiated patch process updates the database software and the OS, allowing for a rolling update strategy on the database nodes, minimizing downtime. Storage nodes are updated separately.

The OCI console-initiated patch process only patches the storage servers; database nodes require manual OS patching.

Q63. Which two functionalities are provided by the SQL Performance Analyzer (SPA) within Database Management, aiding in cloud database tuning?

Automatically rewrite SQL queries to improve their performance.

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

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

Q64. Which statement accurately describes the function of the HeatWave service in relation to a standard MySQL database?

HeatWave is a standalone database system that replaces MySQL, offering enhanced security features.

HeatWave provides an in-memory, massively parallel query accelerator to MySQL, improving analytical query performance.

HeatWave is a specialized version of MySQL designed solely for transactional workloads, optimized for high concurrency.

HeatWave acts as a caching layer in front of MySQL, speeding up access to frequently accessed data.

HeatWave is a clustering solution, where a single MySQL instance is split into multiple parts.

Q65. Which two statements accurately describe the Database Management’s Autonomous Database monitoring capability?

Database Management provides real-time and historical performance data, but is limited to monitoring CPU utilization on Autonomous Databases.
