You have been tasked with provisioning an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster to deploy new applications and manage existing ones. Which two statements are FALSE?
- A. To access the cluster using kubectl, you have to set up a Kubernetes configuration file stored in the
$HOME/.kube directory - B. The only available option when a cluster's Kubernetes API endpoint has a public IP address is to control the cluster locally using kubectl and the Kubernetes Dashboard
- C. To access the cluster using kubectl, you have to set up a Kubernetes manifest file stored in the $HOME/.
manifest directory - D. When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file
Answer: B,C
Explanation:
Setting up a Kubernetes manifest file in the $HOME/.manifest directory is not a standard practice for accessing a Kubernetes cluster using kubectl. Manifest files are used to define and manage Kubernetes resources, such as pods, deployments, and services, but they are not used for configuring access to the cluster.
While controlling the cluster locally using kubectl and the Kubernetes Dashboard is one way to interact with a cluster, it is not the only available option when a cluster's Kubernetes API endpoint has a public IP address.
You can also access and manage the cluster remotely using kubectl from any environment that has network connectivity to the cluster.
