What could the configuration error be?

• A.More stages were added than required to the build pipeline.
• B.Dynamic Groups access and OCI IAM policies to the code repository are not set.

A DevOps Engineer is tasked with providing a solution, which will help in easy management of deployed applications and troubleshoot them on the Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE). What are three actions the DevOps Engineer must perform to accomplish the given task? (Choose three.)

• A.Manually deploy the Kubernetes dashboard on an existing cluster and access it using the URL: hs://localhost:8001/api/vi/namespaces/kube-dashboard/services/httparkubernete dashboard:/proxy/#!/login
• B.Manually deploy the Kubernetes dashboard on an existing cluster and access it using the URL: dashboard:/proxy/#!/login http://localhost:8001/api/vi/namespaces/kube-system/services/httpsikubernetes.
• C.Create a service account and the clusterrolebinding, obtain an authentication token for the service account using kubectl command, and run a kubectl proxy command to enable the kubernetes dashboard
• D.Use the default dashboard that comes configured with the Kubernetes implementation on the Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE).
  Automatically deploy the Kubernetes dashboard during cluster creation, create the cluster using the API and set the iskubernetesDashboardEnabled attribute to true and access it using the http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login
• E.Automatically deploy the Kubernetes dashboard during cluster creation, create the cluster using the API and set the iskubernetesDashboardEnabled attribute to true and access it using the URL: http://localhost:8001/api/v1/namespaces/kube-dashboard/services/httparkubernetes dashboard:/proxy/'/login
