Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Executing pre-checks in the target DR region to validate resource readiness and configurations
Why this is correct
Pre-checks validate that all required infrastructure and permissions are in place before executing a failover.
- ✗
Manually deleting all IAM policies in the primary region during normal operations
Why it's wrong here
Deleting IAM policies breaks access control and is not part of a DR runbook.
- ✗
Format-all commands on primary database storage volumes prior to initiating DR
Why it's wrong here
Formatting primary storage prematurely destroys data before confirmation of failover.
- ✓
Verifying database role transition and redo application status on the standby database
Why this is correct
Ensuring the database is promoted and in sync is critical for application data integrity.
- ✓
Orchestrating traffic rerouting via DNS or Load Balancers to point clients to the DR region
Why this is correct
Rerouting traffic ensures incoming client requests reach the active DR environment.
