2V0-71.23 Question 226
Select 3You are managing a Kubernetes cluster integrated with VMware Tanzu, and your team wants to dynamically provision persistent storage for stateful workloads. They have decided to use the Container Storage Interface (CSI). Which of the following are key benefits of using CSI in this scenario?
- A
CSI allows Kubernetes to interface with multiple storage providers without modifying the core Kubernetes code.
- B
CSI requires manual creation of PersistentVolume (PV) objects, as it does not support dynamic provisioning.
- C
CSI enables storage features such as snapshots and cloning, depending on the capabilities of the storage provider.
- D
CSI is tied exclusively to VMware vSphere storage systems and does not support third-party storage providers.
- E
CSI allows different types of storage systems to be integrated into Kubernetes in a consistent and standardized way.
Show answer and explanation
Correct answers: A, C, E
Explanation
The Container Storage Interface (CSI) is a standardized API that allows Kubernetes to interact with various storage providers. It decouples storage logic from Kubernetes core, enabling dynamic provisioning and advanced storage features like snapshots and cloning, as long as these capabilities are supported by the underlying storage provider. It also ensures a consistent and standardized way to integrate diverse storage solutions into Kubernetes, making it a key component for managing stateful workloads effectively.
- A. Correct.
Correct: CSI decouples storage provider implementations from the Kubernetes core, enabling Kubernetes to support a wide variety of storage systems without requiring changes to its core code.
- B. Incorrect.
Incorrect: CSI supports dynamic provisioning through StorageClasses, which automatically creates PersistentVolume (PV) objects when a PersistentVolumeClaim (PVC) is made.
- C. Correct.
Correct: Depending on the storage provider's implementation, CSI can enable advanced storage features such as snapshots, cloning, and volume expansion.
- D. Incorrect.
Incorrect: CSI is a standardized interface that supports a wide range of third-party storage providers, not just VMware vSphere storage.
- E. Correct.
Correct: CSI provides a consistent framework for integrating various storage systems into Kubernetes, making it easier to manage storage across different environments.
