A company is running an application on Amazon EC2 instances in an Auto Scaling group. Recently, an issue occurred that prevented EC2 instances from launching successfully, and it took several hours for the Support team to discover the issue. The Support team wants to be notified by email whenever an EC2 instance does not start successfully.
Which action will accomplish this?
B

A company uses AWS Storage Gateway in file gateway mode in front of an Amazon S3 bucket that is used by multiple resources. In the morning when business begins, users do not see the objects processed by a third party the previous evening. When a DevOps engineer looks directly at the S3 bucket, the data is there, but it is missing in Storage Gateway.
Which solution ensures that all the updated third-party files are available in the morning?
A
A DevOps engineer sets up two Amazon S3 event notifications for an S3 bucket from the S3 console. Both event notifications will be invoked when an object PUT action occurs. One event notification will invoke an AWS Lambda function if the file suffix is .csv. Another event notification will invoke an Amazon Simple
Notification Service (Amazon SNS) topic if the file suffix is .xlsx
The DevOps engineer notices that files with the .csv suffix can invoke the Lambda function successfully. However, files with the .xlsx suffix cannot invoke the SNS topic.
Which reason explains why the SNS topic is not invoked when .xlsx files are added to the S3 bucket?
B
A rapidly growing company wants to scale for Developer demand for AWS development environments. Development environments are created manually in the
AWS Management Console. The Networking team uses AWS CloudFormation to manage the networking infrastructure, exporting stack output values for the
Amazon VPC and all subnets. The development environments have common standards, such as Application Load Balancers, Amazon EC2 Auto Scaling groups, security groups, and Amazon DynamoDB tables.
To keep up with the demand, the DevOps Engineer wants to automate the creation of development environments. Because the infrastructure required to support the application is expected to grow, there must be a way to easily update the deployed infrastructure. CloudFormation will be used to create a template for the development environments.
Which approach will meet these requirements and quickly provide consistent AWS environments for Developers?
A
A DevOps engineer notices that all Amazon EC2 instances running behind an Application Load Balancer in an Auto Scaling group are failing to respond to user requests. The EC2 instances are also failing target group HTTP health checks.
Upon inspection, the engineer notices the application process was not running in any EC2 instances. There are a significant number of out of memory messages in the system logs. The engineer needs to improve the resilience of the application to cope with a potential application memory leak. Monitoring and notifications should be enabled to alert when there is an issue.
Which combination of actions will meet these requirements? (Choose two.)

A company wants to migrate a legacy application to AWS and develop a deployment pipeline that uses AWS services only. A DevOps engineer is migrating all of the application code from a Git repository to AWS CodeCommit while preserving the history of the repository. The DevOps engineer has set all the permissions within CodeCommit, installed the Git client and the AWS CLI on a local computer, and is ready to migrate the repository.
Which actions will follow?
A
A company is using AWS to deploy an application. The development team must automate the deployments. The team has created an AWS CodePipeline pipeline to deploy the application to Amazon EC2 instances using AWS CodeDeploy after it has been built using AWS CodeBuild.
The team wants to add automated testing to the pipeline to confirm that the application is healthy before deploying the code to the EC2 instances. The team also requires a manual approval action before the application is deployed, even if the tests are successful. The testing and approval must be accomplished at the lowest costs, using the simplest management solution.
Which solution will meet these requirements?
B
A DevOps engineer wants to deploy a serverless web application that is based on AWS Lambda. The deployment must meet the following requirements:
✑ Provide staging and production environments.
✑ Restrict developers from accessing the production environment.
✑ Avoid hardcoding passwords in the Lambda functions.
✑ Store source code in AWS CodeCommit.
✑ Use AWS CodePipeline to automate the deployment.
What is the MOST operationally efficient solution that meets these requirements?
A
A company wants to use AWS development tools to replace its current bash deployment scripts. The company currently deploys a LAMP application to a group of
Amazon EC2 instances behind an Application Load Balancer (ALB). During the deployments, the company unit tests the committed application, stops and starts services, unregisters and re-registers instances with the load balancer, and updates file permissions. The company wants to maintain the same deployment functionality through the shift to using AWS services.
Which solution will meet these requirements?
B
A company gives its employees limited rights to AWS. DevOps engineers have the ability to assume an administrator role. For tracking purposes, the security team wants to receive a near-real-time notification when the administrator role is assumed.
How should this be accomplished?
