Question 1 of 30

An Oracle RAC database instance on Node 1 unexpectedly terminated, causing a critical application outage. The system administrator, Elara, observes that the Clusterware has not automatically restarted the instance on Node 1, nor has it initiated an automatic instance migration to another node. Several dependent services are now unavailable. Elara needs to restore service as quickly as possible while ensuring the integrity of the cluster and data. Which immediate course of action demonstrates the most advanced understanding of Grid Infrastructure administration and problem resolution in such a scenario?

Thoroughly investigate the root cause of the instance termination on Node 1 by reviewing alert logs, Grid Infrastructure logs, and OS-level diagnostics before initiating any recovery actions.
Immediately execute a cluster-wide reboot to ensure all Grid Infrastructure components and database instances are reset to a known state.
Force an instance migration of the affected database to Node 2 without initial diagnostics, assuming a node-specific issue.
Disable automatic instance restarts for the database and manually attempt to start the instance on Node 1 after a brief cooling-off period.
