A DevOps engineer is asked to access an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster to deploy new applications and manage existing ones.
Which two statements are true? (Choose two.)
ATo access the cluster using kubectl, you have to set up a Kubernetes configuration file for the cluster. The kubeconfig file by default is named config and stored in the $HOME/.kube directory.
BWhen 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.
CGenerating an API signing key pair is not required while setting up cluster access using local machine if the public key is not already uploaded in the console.
DThe 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.
ETo access the cluster using kubectl, you have to set up a Kubernetes manifest file for the cluster. The kubeconfig file by default is named config and stored in the $HOME/.manifest directory.

A
B
C
D
The Kubernetes Master node serves as the central control plane for managing the cluster’s resources and orchestrating workload deployment.
What are the primary responsibilities of the Kubernetes Master node?
AThe Master node is primarily tasked with executing application workloads and ensuring their availability within the cluster.
BThe Master node oversees the scheduling and allocation of cluster resources, ensuring optimal utilization across nodes.
CThe Master node monitors network traffic within the cluster, ensuring secure communication and efficient data transfer between nodes.
DThe Master node serves as a repository for storing container images, facilitating rapid deployment and scaling of applications.
As a DevOps Engineer, you are tasked with explaining the key concepts of Terraform to a new team member. You want to ensure they understand the fundamental concepts of Terraform.
