2V0-71.23 Question 225
Select 3A Kubernetes administrator is deploying a Tanzu Kubernetes Grid (TKG) cluster and needs to integrate a shared storage solution that can dynamically provision persistent volumes for applications. The administrator decides to use a Container Storage Interface (CSI) driver. Which of the following statements about CSI in the context of Tanzu Kubernetes Grid are accurate?
- A
CSI drivers allow Kubernetes to interact with different storage systems for dynamic provisioning of persistent volumes.
- B
CSI drivers are embedded within the Kubernetes core and cannot be updated independently of Kubernetes versions.
- C
The vSphere CSI driver is supported for use with Tanzu Kubernetes Grid to provision persistent volumes on vSphere storage.
- D
A CSI driver must be manually installed in every Tanzu Kubernetes Grid cluster, as it is not automatically deployed.
- E
CSI drivers support advanced storage functionalities such as snapshots and volume cloning depending on the storage system.
Show answer and explanation
Correct answers: A, C, E
Explanation
Container Storage Interface (CSI) drivers allow Kubernetes to interface with external storage systems for dynamic provisioning of persistent volumes, enabling the flexibility needed for modern containerized workloads. In Tanzu Kubernetes Grid, the vSphere CSI driver is a common choice for provisioning storage in vSphere environments. CSI is designed to be external to the Kubernetes core, allowing for independent updates and advanced features like snapshots and cloning. This decoupling ensures compatibility and feature enhancement without the need for Kubernetes version upgrades.
- A. Correct.
Correct: CSI drivers enable Kubernetes to interface with external storage systems for dynamic provisioning, making them essential for persistent storage in Kubernetes environments.
- B. Incorrect.
Incorrect: CSI drivers are designed to be external to the Kubernetes core, allowing independent updates without requiring a Kubernetes version change.
- C. Correct.
Correct: The vSphere CSI driver is a supported and commonly used driver for Tanzu Kubernetes Grid, especially in vSphere environments, to manage persistent volumes.
- D. Incorrect.
Incorrect: While some CSI drivers may require manual installation, Tanzu Kubernetes Grid distributions often include automated processes for deploying certain drivers, such as the vSphere CSI driver.
- E. Correct.
Correct: CSI drivers can provide advanced features like snapshots, volume cloning, and resizing, depending on the capabilities of the underlying storage system and the driver implementation.
