Which combination of actions should be taken to address the latency issues?
(Choose three.)
Create a new DynamoDB table in the new Region with cross-Region replication enabled.
Create new ALB and Auto Scaling group global resources and configure the new ALB to direct traffic to the new Auto Scaling group.
Create new ALB and Auto Scaling group resources in the new Region and configure the new ALB to direct traffic to the new Auto Scaling group.
Create Amazon Route 53 records, health checks, and latency-based routing policies to route to the ALB.
Create Amazon Route 53 aliases, health checks, and failover routing policies to route to the ALB.
Convert the DynamoDB table to a global table.
Explanations:
Creating a new DynamoDB table in the new Region with cross-Region replication would not effectively reduce latency. Instead, it introduces complexity without addressing immediate latency issues, as users in the new Region would still face delays due to data not being stored locally.
Creating new global resources (ALB and Auto Scaling group) without a proper traffic routing strategy does not address latency issues effectively. It also adds unnecessary complexity because traffic is not being directed based on proximity to the user.
Creating new ALB and Auto Scaling group resources in the new Region will allow the application to run closer to users in that Region, significantly reducing latency and improving performance for those users.
Configuring Amazon Route 53 with latency-based routing policies helps direct user traffic to the closest ALB. This optimizes application response times by minimizing the distance data must travel, thus improving user experience and availability.
Using failover routing policies is more suitable for high availability scenarios where you want to switch traffic in case of failure, not for reducing latency. It does not provide the latency optimization needed for users in the new Region.
Converting the DynamoDB table to a global table allows for low-latency access to data across multiple Regions. This is beneficial for users in both Regions as it ensures that they have access to the most recent data with minimal delays.
