The company needs to configure the EKS cluster with the appropriate node groups and scaling policies. Given that the application experiences variable workloads, what is the best approach to ensure that the EKS cluster can automatically scale the number of nodes based on demand while maintaining high availability across the AZs?

Accepted Answer

Configure the EKS cluster with an Auto Scaling Group (ASG) that spans multiple AZs and set up Cluster Autoscaler to manage the scaling of the node groups based on resource requests and limits defined in the pods.

Question 17

A company is experiencing fluctuating traffic patterns on its e-commerce platform, leading to inconsistent performance and increased costs. The architecture is currently set up with an Auto Scaling group configured to scale out based on CPU utilization. The team is considering implementing a more sophisticated Auto Scaling strategy that includes both scheduled scaling and dynamic scaling based on multiple metrics. If the team decides to implement a scheduled scaling policy to handle predictable traffic spikes during holiday sales, how should they configure the scaling actions to ensure optimal resource utilization while minimizing costs?

Accepted Answer

Schedule scaling actions to increase the instance count before the expected traffic surge and decrease it after the peak period ends.

Question 18

Accepted Answer

Implement an Auto Scaling group with multiple EC2 instances behind an Application Load Balancer (ALB)

Question 20

A company is planning to deploy a multi-tier application on AWS using Amazon VPC. The application consists of a web tier, an application tier, and a database tier. The web tier needs to be publicly accessible, while the application and database tiers should remain private. The company wants to ensure that the database tier is not directly accessible from the internet and can only be accessed by the application tier. Given this scenario, which configuration would best meet these requirements while ensuring optimal security and performance?

Accepted Answer

Create a public subnet for the web tier, a private subnet for the application tier, and another private subnet for the database tier, using security groups to control access between the application and database tiers.

Question 21

A company is developing a microservices architecture using Amazon API Gateway to manage its APIs. They want to implement a throttling mechanism to control the rate of requests to their backend services. The company anticipates a peak load of 1,000 requests per second and wants to ensure that no single client can exceed 100 requests per second. Additionally, they want to allow a burst capacity of 200 requests for short periods. How should they configure the API Gateway to meet these requirements while ensuring that the backend services remain responsive?

Accepted Answer

Set a rate limit of 100 requests per second with a burst limit of 200 requests.
