Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable all health checks on load balancers to prevent false alarms during failover.
Why it's wrong here
Disabling health checks hinders the system's ability to detect and route around failures.
- ✓
Automate failover orchestration using tools like OCI Full Stack Disaster Recovery.
Why this is correct
Automation reduces human error and speeds up recovery execution.
- ✓
Conduct regular disaster recovery drills using non-disruptive testing features like Snapshot Standby.
Why this is correct
Regular drills validate RTO/RPO assumptions and team readiness.
- ✗
Rely solely on manual documentation stored on local laptops for failover steps.
Why it's wrong here
Manual documentation leads to delays, errors, and high RTO.
- ✓
Ensure adequate compute and database capacity is provisioned or reserved in the target DR region.
Why this is correct
Capacity constraints in the DR region can prevent successful failover.
