question 435

Multiple Choice

A solutions architect is designing the architecture for a new web application. The application will run on AWS Fargate containers with an Application Load Balancer (ALB) and an Amazon Aurora PostgreSQL database. The web application will perform primarily read queries against the database. What should the solutions architect do to ensure that the website can scale with increasing traffic? (Choose two.)

• A) Enable auto scaling on the ALB to scale the load balancer horizontally.
• B) Configure Aurora Auto Scaling to adjust the number of Aurora Replicas in the Aurora cluster dynamically.
• C) Enable cross-zone load balancing on the ALB to distribute the load evenly across containers in all Availability Zones.
• D) Configure an Amazon Elastic Container Service (Amazon ECS) cluster in each Availability Zone to distribute the load across multiple Availability Zones.
• E) Configure Amazon Elastic Container Service (Amazon ECS) Service Auto Scaling with a target tracking scaling policy that is based on CPU utilization.
