Question 1 of 30

Following a complex Oracle Database migration to Oracle Cloud Infrastructure (OCI), a critical application experiencing intermittent performance degradation has been reported. The root cause remains elusive, with initial investigations pointing towards potential bottlenecks in the integration layer between the migrated database and legacy on-premises systems, alongside possible resource contention within the OCI tenancy. The project lead must coordinate a rapid, multi-faceted response to restore service stability while adhering to strict service level agreements (SLAs) and ensuring minimal impact on ongoing business operations. Which approach best demonstrates the required competencies for effective incident resolution in this scenario?

Implement a comprehensive, phased diagnostic approach utilizing OCI monitoring services (e.g., Oracle Cloud Infrastructure Monitoring, Performance Hub) to gather granular performance metrics from the database, compute, and network layers, concurrently engaging cross-functional teams (database administrators, network engineers, application developers) for collaborative root cause analysis and iterative solution validation.
Immediately roll back the entire database migration to the on-premises environment to stabilize the critical application, while initiating a separate, long-term project to re-evaluate the migration strategy and identify a more robust integration solution.
Escalate the issue to Oracle Support exclusively, providing them with all available logs and performance data, and await their detailed analysis and recommended remediation steps before implementing any changes.
Focus solely on optimizing the Oracle Database parameters within OCI, assuming the integration layer and application logic are functioning correctly, and postpone further investigation into other potential contributing factors until database-level tuning is complete.
