Question
A company is building a critical data processing application that will run on Amazon EC2 instances. The company must not run any two nodes on the same underlying hardware. The company requires at least 99.99% availability for the application. Which solution will meet these requirements?
Options
- ADeploy the application to one Availability Zone by using a cluster placement group strategy.
- BDeploy the application to three Availability Zones by using a spread placement group strategy.
- CDeploy the application to three Availability Zones by using a cluster placement group strategy.
- DDeploy the application to one Availability Zone by using a partition placement group strategy.

Explanation
A spread placement group is designed to deploy each instance on distinct underlying hardware, reducing the risk of simultaneous failures. By spreading instances across multiple Availability Zones, you achieve high availability and fault tolerance, meeting the 99.99% uptime requirement. Spread placement groups are ideal for critical applications that require maximum resilience to single hardware failures. Neither cluster nor partition strategies offer the same guarantee of separation combined with cross-AZ distribution.
