Question 640
Which high-level AWS choice is most appropriate for this business requirement? An insurance website must continue serving customers if one data center within its selected AWS Region becomes unavailable.
Explanation
Correct Answer
Run redundant application components across more than one Availability Zone. The case involves: An insurance website must continue serving customers if one data center within its selected AWS Region becomes unavailable. The central AWS principle is that distributing workloads across multiple Availability Zones can improve high availability. What matters is: Look for a single-zone failure requirement and independent facilities within one Region. Recommended direction: Run redundant application components across more than one Availability Zone. Expected indication of success: A simulated zone failure leaves a healthy application path available to customers. Caveat: Multi-AZ design does not protect against every Region-wide outage.
Incorrect Answers
Cloud self-service provisioning improves agility by allowing teams to acquire resources rapidly. That addresses a different mechanism; this question turns on Run redundant application components across more than one Availability.
The AWS global footprint offers regional deployment choices without building separate company-owned facilities. That observation may hold without resolving the relevant issue: Run redundant application components across more than one Availability.
AWS Regions provide geographic locations where suitable services can be deployed closer to customers. It does not verify the requested outcome; here the decisive check concerns Run redundant application components across more than one Availability.
