A user reports that they can connect to the Kubernetes API server of their VKS cluster from the corporate network, but they cannot access a web application deployed inside the cluster from the same network. The application is exposed via a LoadBalancer service. The administrator checks the VKS cluster and confirms the service has an external IP assigned. What should the administrator check next?

The kubeconfig file used by the user to access the cluster.

The NSX-T Data Center load balancer configuration and the network policies applied to the namespace.

The DNS configuration of the corporate network.

The storage class used by the application's persistent volume claims.

A VKS cluster's nodes are all showing as 'NotReady' in the Kubernetes API. The administrator checks the vSphere UI and sees that the VMs are running and powered on. What is the most likely cause of this issue?

The VMs cannot communicate with the Kubernetes API server due to a network policy or NSX-T configuration issue.

The VMs are running an outdated Kubernetes version.

The VMs are running out of disk space.

The VMs are not registered with the vCenter Server.

A vSphere administrator creates a new namespace for a development team. When a developer tries to create a pod in the namespace, they receive a 'forbidden' error. The developer can successfully run 'kubectl get namespaces' and can see the new namespace. What is the most likely cause of this issue?

The namespace is not associated with a vSphere storage policy.

The developer is using an outdated kubeconfig file.

The developer's Kubernetes role does not have permission to create resources in the namespace.

The namespace does not have a resource quota configured.

A VKS cluster has recurring provisioning failures due to insufficient IP addresses in the namespace's network. Which remediation is most likely to prevent this issue?

Change the storage class to a more efficient one.

Disable the load balancer for the VKS cluster.

Reduce the number of replicas in the VKS cluster.

Increase the size of the subnet allocated to the namespace.

A VKS cluster provisioning fails, and the administrator needs to identify the root cause. Which command should the administrator use to view the events and status of the VKS cluster?

kubectl get events --all-namespaces
