B. auto scaling groups can not span multi region

Option A (creating an Auto Scaling group across two Regions) introduces additional complexity and potential replication challenges, which may not be necessary for achieving high availability within a single Region. Option C (creating an Auto Scaling template for another Region) suggests multi-region redundancy, which may not be the most straightforward solution for achieving high availability without modifying the application. Option D (changing the ALB to a round-robin configuration) does not provide the desired high availability. Round-robin configuration alone does not ensure fault tolerance and does not leverage multiple Availability Zones for resilience. Hence, modifying the Auto Scaling group to use three instances across each of two Availability Zones is the appropriate choice to provide high availability for the multi-tier application.

Option B. Modify the Auto Scaling group to use three instances across each of the two Availability Zones.

B. auto scaling groups cannot span multi region

Option B. Modify the Auto Scaling group to use three instances across each of the two Availability Zones. This option would provide high availability by distributing the front-end web servers across multiple Availability Zones. If there is an issue with one Availability Zone, the other Availability Zone would still be available to serve traffic. This would ensure that the application remains available and highly available even if there is a failure in one of the Availability Zones.

Option B

Agreed

B option B This architecture provides high availability by having multiple Availability Zones hosting the same application. This allows for redundancy in case one Availability Zone experiences downtime, as traffic can be served by the other Availability Zone. This solution also increases scalability and performance by allowing traffic to be spread across two Availability Zones.
