DOP-C02 Exam
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 is building a serverless application that uses AWS Lambda functions to process data.
A BeginResponse Lambda function initializes data in response to specific application events. The company needs to ensure that a large number of Lambda functions are invoked after the BeginResponse Lambda function runs. Each Lambda function must be invoked in parallel and depends on only the outputs of the BeginResponse Lambda function. Each Lambda function has retry logic for invocation and must be able to fine-tune concurrency without losing data.
Which solution will meet these requirements with the MOST operational efficiency?
A global company uses Amazon S3 to host its product catalog website in the us-east-1 Region. The company must improve website performance for users across different geographical regions and must reduce the load on the origin server. The company must implement a highly available cross-Region solution that uses Amazon CloudFront. Which solution will meet these requirements with the LEAST operational effort?
