Your company needs to deploy a set of Azure Kubernetes clusters. Each cluster has different requirements. The requirements are given below-

Deployment

Requirement

testclusterA

This cluster needs to access an SMB-based file share from the container’s file system

testclusterB

This cluster needs to access files on a managed disk from the container’s file system

testclusterC

This cluster needs to access X.509 certificates from the container’s file system securely

Which of the following would you use in the deployment of the cluster testclusterA?

Answer options:

A.SecretProviderClass
B.Blobfuse-flexvol
C.kubernetes.io/azure-disk
D.kubernetes.io/azure-file
E.volume.beta.kubernetes.io/storage-provisioner

Answer – D 
In the YAML deployment file, you can use the kubernetes.io/azure-file provisioner to access an SMB-based file share. 
This is also mentioned in the Microsoft documentation. 

Since this is clearly mentioned, all other options are incorrect.
