A DevOps team manages an API running on-premises that serves as a backend for an Amazon API Gateway endpoint. Customers have been complaining about high response latencies, which the development team has verified using the API Gateway latency metrics in Amazon CloudWatch. To identify the cause, the team needs to collect relevant data without introducing additional latency.
Which actions should be taken to accomplish this? (Choose two.)
A company has developed a static website hosted on an Amazon S3 bucket. The website is deployed using AWS CloudFormation. The CloudFormation template defines an S3 bucket and a custom resource that copies content into the bucket from a source location.
The company has decided that it needs to move the website to a new location, so the existing CloudFormation stack must be deleted and re-created. However, CloudFormation reports that the stack could not be deleted cleanly.
What is the MOST likely cause and how can the DevOps engineer mitigate this problem for this and future versions of the website?
A company has a mobile application that makes HTTP API calls to an Application Load Balancer (ALB). The ALB routes requests to an AWS Lambda function. Many different versions of the application are in use at any given time, including versions that are in testing by a subset of users. The version of the application is defined in the user-agent header that is sent with all requests to the API.
After a series of recent changes to the API, the company has observed issues with the application. The company needs to gather a metric for each API operation by response code for each version of the application that is in use. A DevOps engineer has modified the Lambda function to extract the API operation name, version information from the user-agent header and response code.
Which additional set of actions should the DevOps engineer take to gather the required metrics?
A global company manages multiple AWS accounts by using AWS Control Tower. The company hosts internal applications and public applications.
Each application team in the company has its own AWS account for application hosting. The accounts are consolidated in an organization in AWS Organizations. One of the AWS Control Tower member accounts serves as a centralized DevOps account with CI/CD pipelines that application teams use to deploy applications to their respective target AWS accounts. An 1AM role for deployment exists in the centralized DevOps account.
An application team is attempting to deploy its application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster in an application AWS account. An 1AM role for deployment exists in the application AWS account. The deployment is through an AWS CodeBuild project that is set up in the centralized DevOps account. The CodeBuild project uses an 1AM service role for CodeBuild. The deployment is failing with an Unauthorized error during attempts to connect to the cross-account EKS cluster from CodeBuild.
Which solution will resolve this error?
A DevOps engineer needs to implement a solution to install antivirus software on all the Amazon EC2 instances in an AWS account. The EC2 instances run the most recent version of Amazon Linux .
The solution must detect all instances and must use an AWS Systems Manager document to install the software if the software is not present.
Which solution will meet these requirements?
A company is experiencing failures in its AWS CodeDeploy deployments for a critical application. The application is deployed on Amazon EC2 instances. A DevOps engineer must analyze the failed deployments to identify the root cause of the failures.
Which solution will provide the appropriate information to troubleshoot the deployment issues?
A software as a service (SaaS) company uses an Amazon Elastic Container Service (Amazon ECS) cluster behind an Application Load Balancer (ALB) to provide real-time analytics services to clients. The company is using AWS CodePipeline and AWS CodeDeploy to set up a blue/green deployment process for the solution.
The company wants the deployment process to automatically shift traffic in equal increments over a specified total deployment time without any manual intervention. The deployment must ensure zero downtime and provide seamless traffic shifting.
Which solution will meet these requirements?
A company has a guideline that every Amazon EC2 instance must be launched from an AMI that the company ' s security team produces. Every month, the security team sends an email message with the latest approved AMIs to all the development teams. The development teams use AWS CloudFormation to deploy their applications. When developers launch a new service, they have to search their email for the latest AMIs that the security department sent. A DevOps engineer wants to automate the process that the security team uses to provide the AMI IDs to the development teams. What is the MOST scalable solution that meets these requirements?
A company uses an Amazon Elastic Kubernetes Service (Amazon EKS) cluster to host its machine learning (ML) application. As the ML model and the container image size grow, the time that new pods take to start up has increased to several minutes.
A DevOps engineer needs to reduce the startup time to seconds. The solution must also reduce the startup time to seconds when the pod runs on nodes that were recently added to the cluster.
The DevOps engineer creates an Amazon EventBridge rule that invokes an automation in AWS Systems Manager. The automation prefetches the container images from an Amazon Elastic Container Registry (Amazon ECR) repository when new images are pushed to the repository. The DevOps engineer also configures tags to be applied to the cluster and the node groups.
What should the DevOps engineer do next to meet the requirements?
A company runs an application that uses an Amazon S3 bucket to store images. A DevOps engineer needs to implement a multi-Region disaster recovery (DR) strategy for the S3 objects. The DevOps engineer enables two-way replication between the S3 buckets.
The company must be able to fail over to a second S3 bucket that is in a second AWS Region. When an image is added to either S3 bucket, the image must be replicated to the other S3 bucket within 15 minutes .
Which combination of steps will meet these requirements in the MOST operationally efficient way? ( Select THREE. )
