Exam AWS Certified DevOps Engineer - Professional DOP-C02 topic 1 question 151 discussion

Exam question from Amazon's AWS Certified DevOps Engineer - Professional DOP-C02
Question #: 151
Topic #: 1
[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

A DevOps engineer wants to find a solution to migrate an application from on premises to AWS. The application is running on Linux and needs to run on specific versions of Apache Tomcat, HAProxy, and Varnish Cache to function properly. The application's operating system-level parameters require tuning. The solution must include a way to automate the deployment of new application versions. The infrastructure should be scalable and faulty servers should be replaced automatically.

Which solution should the DevOps engineer use?

  • A. Upload the application as a Docker image that contains all the necessary software to Amazon ECR. Create an Amazon ECS cluster using an AWS Fargate launch type and an Auto Scaling group. Create an AWS CodePipeline pipeline that uses Amazon ECR as a source and Amazon ECS as a deployment provider.
  • B. Upload the application code to an AWS CodeCommit repository with a saved configuration file to configure and install the software. Create an AWS Elastic Beanstalk web server tier and a load balanced-type environment that uses the Tomcat solution stack. Create an AWS CodePipeline pipeline that uses CodeCommit as a source and Elastic Beanstalk as a deployment provider.
  • C. Upload the application code to an AWS CodeCommit repository with a set of .ebextensions files to configure and install the software. Create an AWS Elastic Beanstalk worker tier environment that uses the Tomcat solution stack. Create an AWS CodePipeline pipeline that uses CodeCommit as a source and Elastic Beanstalk as a deployment provider.
  • D. Upload the application code to an AWS CodeCommit repository with an appspec.yml file to configure and install the necessary software. Create an AWS CodeDeploy deployment group associated with an Amazon EC2 Auto Scaling group. Create an AWS CodePipeline pipeline that uses CodeCommit as a source and CodeDeploy as a deployment provider.

I go with D, simply because with Fargate you have very limited access to the OS.

Selected Answer: D
While option A is a strong candidate due to its serverless nature and ease of deployment, option D is the most suitable solution given the need for specific software versions, OS-level tuning, and the requirement for a scalable and fault-tolerant infrastructure. Option D provides the necessary control over the software environment and infrastructure configuration, along with the benefits of automation and scalability.

Selected Answer: B
Option B is clearly the preferred option: - Uses Elastic Beanstalk web server tier with load balancing - Provides managed Tomcat platform - Supports configuration files for software installation - Includes auto-scaling and health monitoring - Uses CodePipeline for automated deployments - Appropriate for web applications Option A: Containerization created unnecessary overhead and it will turn up more expensive Option C: Worker tier is for background processes, not suitable for web applications Option D: - More manual configuration required - Less managed service features - No built-in platform support - More complex to maintain

AWS Fargate does not allow direct tuning of Linux OS-level parameters because it is a fully managed, serverless compute engine for containers. With Fargate, AWS abstracts the underlying infrastructure, including the operating system, and does not expose granular OS-level configurations.

I doubt this question will come up since both A and D are correct: https://aws.amazon.com/blogs/containers/announcing-additional-linux-controls-for-amazon-ecs-tasks-on-aws-fargate/ they need to add some words to the question tat force you to choose either A or D

Today we’re excited to announce that customers can now tune Linux kernel parameters in ECS tasks on AWS Fargate. Tuning Linux kernel parameters can help customers optimize their network throughput when running containerized network proxies or achieve higher levels of workload resilience by terminating stale connections. This launch provides parity for ECS tasks launched on AWS Fargate and Amazon EC2 container instances. https://aws.amazon.com/blogs/containers/announcing-additional-linux-controls-for-amazon-ecs-tasks-on-aws-fargate/

The question only needs Linux OS, its not asking for any extra customizations. AWS fargate allows you to choose the linux platform - and you can package the specific packages in a docker container.
