DOP-C02 Exam
A company has developed a web application that conducts seasonal sales on public holidays. The web application is deployed on AWS and uses AWS services for storage, database, computing, and encryption. During seasonal sales, the company expects high network traffic from many users. The company must receive insights regarding any unexpected behavior during the sale. A DevOps team wants to review the insights upon detecting anomalous behaviors during the sale. The DevOps team wants to receive recommended actions to resolve the anomalous behaviors. The recommendations must be provided on the provisioned infrastructure to address issues that might occur in the future.
Which combination of steps will meet these requirements with the LEAST operational overhead? (Select TWO.)
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 DevOps engineer manages an AWS CodePipeline pipeline that builds and deploys a web application on AWS. The pipeline has a source stage, a build stage, and a deploy stage. When deployed properly, the web application responds with a 200 OK HTTP response code when the URL of the home page is requested. The home page recently returned a 503 HTTP response code after CodePipeline deployed the application. The DevOps engineer needs to add an automated test into the pipeline. The automated test must ensure that the application returns a 200 OK HTTP response code after the application is deployed. The pipeline must fail if the response code is not present during the test. The DevOps engineer has added a CheckURL stage after the deploy stage in the pipeline. What should the DevOps engineer do next to implement the automated test?
