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.
