A Company Has Developed a Microservices Application

question 214

Multiple Choice

A company has developed a microservices application. It uses a client-facing API with Amazon API Gateway and multiple internal services hosted on Amazon EC2 instances to process user requests. The API is designed to support unpredictable surges in traffic, but internal services may become overwhelmed and unresponsive for a period of time during surges. A solutions architect needs to design a more reliable solution that reduces errors when internal services become unresponsive or unavailable. Which solution meets these requirements?

• A) Use AWS Auto Scaling to scale up internal services when there is a surge in traffic.
• B) Use different Availability Zones to host internal services. Send a notification to a system administrator when an internal service becomes unresponsive.
• C) Use an Elastic Load Balancer to distribute the traffic between internal services. Configure Amazon CloudWatch metrics to monitor traffic to internal services.
• D) Use Amazon Simple Queue Service (Amazon SQS) to store user requests as they arrive. Change the internal services to retrieve the requests from the queue for processing.
