A company wants to migrate its main application to Amazon EC2.The application must provide low latency to users residing in two different geographic locations.The architecture of the application must have disaster recovery capabilities.

How can these requirements be met?

Deploy the application on an EC2 instance and set up EC2 automatic recovery

Deploy the application on multiple EC2 instances running in one Availability Zone

Deploy the application on EC2 instances in Multi-AZs in a single AWS Region

Deploy the application on EC2 instances in multiple AWS Regions.

Explanations:

EC2 automatic recovery provides resilience for a single instance within the same Availability Zone, but it does not cover multiple geographic locations or disaster recovery needs.

Deploying instances in a single Availability Zone does not provide disaster recovery capabilities as it lacks redundancy across locations and AZs.

Multi-AZ in a single AWS Region improves availability but not geographic redundancy, so it does not fully meet low-latency or disaster recovery requirements across regions.

Deploying EC2 instances in multiple AWS Regions provides geographic redundancy, low latency across different locations, and disaster recovery capabilities.

    I think the answer is:
    Deploy the application on EC2 instances in multiple AWS Regions.
