Question 360
Which service-to-requirement explanation best fits this situation: An organization needs recovery options if an entire geographic AWS Region becomes unavailable?
Explanation
Correct Answer
Using more than one Region can improve resilience to region-level failures when data and services are replicated appropriately. This fits the situation: An organization needs recovery options if an entire geographic AWS Region becomes unavailable.
Incorrect Answers
Single-AZ deployment places resources in one Availability Zone rather than spreading risk across AZs. This does not address the need for An organization needs recovery options if an entire geographic AWS Region becomes unavailable. The appropriate Multi-Region deployment applies because Using more than one Region can improve resilience to region-level failures when data and services are replicated appropriately.
Single-Region Multi-AZ only: Improves AZ fault tolerance within one Region but does not protect against a full-Region outage. This does not address the need for An organization needs recovery options if an entire geographic AWS Region becomes unavailable. The appropriate Multi-Region deployment applies because Using more than one Region can improve resilience to region-level failures when data and services are replicated appropriately.
Single edge cache: Holds cached content and is not multi-Region application recovery. This does not address the need for An organization needs recovery options if an entire geographic AWS Region becomes unavailable. The appropriate Multi-Region deployment applies because Using more than one Region can improve resilience to region-level failures when data and services are replicated appropriately.
