2V0-71.23 Question 228
Select 4Your team is deploying a Kubernetes workload on VMware Tanzu that requires persistent storage. You have been asked to use the Container Storage Interface (CSI) to dynamically provision volumes for the workload. Which of the following statements about CSI in a Tanzu environment are correct?
- A
CSI allows Kubernetes to interact with a wide range of storage providers to provision and manage storage dynamically.
- B
CSI drivers must be installed and configured on the Kubernetes nodes to enable storage provisioning.
- C
CSI is a VMware-specific technology that only supports vSphere storage solutions.
- D
Persistent Volumes (PVs) provisioned via CSI are automatically deleted when the associated Persistent Volume Claim (PVC) is deleted, depending on the ReclaimPolicy.
- E
The VMware vSphere CSI driver supports features such as volume snapshots and resizing.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
The Container Storage Interface (CSI) is a CNCF standard that enables Kubernetes to interact with various storage providers in a consistent way. In a VMware Tanzu environment, the vSphere CSI driver allows Kubernetes to dynamically provision storage backed by vSphere. To use CSI, the necessary drivers must be installed, and it supports features like lifecycle management of Persistent Volumes and advanced functionalities like snapshots and resizing. CSI is not VMware-specific, as it is designed to work with any compliant storage provider.
- A. Correct.
Correct: CSI is a standard interface that allows Kubernetes to work with various storage providers, making it highly versatile and not tied to a specific vendor.
- B. Correct.
Correct: For CSI to function, drivers must be installed and configured on the Kubernetes nodes to enable communication with the underlying storage system.
- C. Incorrect.
Incorrect: CSI is a standard developed by the Cloud Native Computing Foundation (CNCF) and is not VMware-specific. While VMware provides a vSphere CSI driver, the standard itself is vendor-agnostic.
- D. Correct.
Correct: The lifecycle of Persistent Volumes provisioned via CSI is managed by Kubernetes, and the ReclaimPolicy (e.g., Delete or Retain) determines whether the volume is deleted when its associated PVC is deleted.
- E. Correct.
Correct: The VMware vSphere CSI driver supports advanced features like volume snapshots and resizing, enhancing storage flexibility and management capabilities.
