An Engineering team manages a Node.js e-commerce application. The current environment consists of the following components: "¢ Amazon S3 buckets for storing content "¢ Amazon EC2 for the front - end web servers "¢ AWS Lambda for executing image processing "¢ Amazon DynamoDB for storing session -related data The team expects a significant increase in traffic to the site. The application should handle the additional load without interruption. The team ran initial tests by adding new servers to the EC2 front -end to handle the larger load, but the instances took up to 20 minutes to become fully configured. The team wants to reduce this configuration time. What changes will the Engineering team need to implement to make the solution the MOST resilient and highly available while meeting the expected increase in demand?
A web application with multiple services runs on Amazon EC2 instances behind an Application Load Balancer. The application stores data in an Amazon RDS Multi -AZ DB instance. The instance health check used by the load balancer returns PASS if at least one service is running on the instance. The company uses AWS CodePipeline with AWS CodeBuild and AWS CodeDeploy steps to deploy code to test and production environments. Recentl y, a new version was unable to connect to the database server in the test environment. One process was running, so the health checks reported healthy and the application was promoted to production, causing a production outage. The company wants to ensure that test builds are fully functional before a promotion to production. Which changes should a DevOps Engineer make to the test and deployment process? (Choose two.)
A company's application is currently deployed to a single AWS Region. Recently, the company opened a new office on a different continent. The users in the new office are experiencing high latency. The company's application runs on Amazon EC2 instances behind an Application Load Balancer (ALB) and uses Amazon DynamoDB as the database layer. The instances run in an EC2 Auto Scaling group across multiple Availability Zones. A DevOps Engineer is tasked with minimizing application response times and improving availability for users in both Regions. Which combination of actions should be taken to address the latency issues? (Choose three.)
A DevOps Engineer is deploying an Amazon API Gateway API with an AWS Lambda function providing the backend functionality. The Engineer needs to record the source IP address and response status of every API call. Which combination of actions should the DevOps Engineer take to implement this functionality? (Choose three.)
A DevOps Engineer at a startup cloud -based gaming company has the task formalizing deployment strategies. The strategies must meet the following requirements: Use standard Git commands, such as git clone and git push for the code repository. Management tools should maximize the use of platform solutions where possible. Deployment packages must be immutable and in the form of Docker images. How can the Engineer meet these requirements?
To run an application, a DevOps Engineer launches an Amazon EC2 instances with public IP addresses in a public subnet. A user data script obtains the application artifacts and installs them on the instances upon launch. A change to the security classification of the application now requires the instances to run wi th no access to the Internet. While the instances launch successfully and show as healthy, the application does not seem to be installed. Which of the following should successfully install the application while complying with the new rule?
