2V0-71.23 Question 268
Single answerYou are tasked with deploying a Tanzu Kubernetes Grid Service cluster on a vSphere environment. The cluster requires high performance and fault tolerance for its persistent volumes. How can you ensure the storage policy applied to the cluster meets these requirements?
- A
Create a vSphere storage policy with RAID 5, set it as the default storage policy, and apply it to the Supervisor Cluster.
- B
Use a vSphere storage policy with RAID 1 mirroring, configure it for high availability, and apply it to the Supervisor Cluster.
- C
Use the default vSAN storage policy provided by vSphere with Tanzu without any modifications.
- D
Manually assign individual datastore clusters to each namespace without using a storage policy.
Show answer and explanation
Correct answer: B
Explanation
In vSphere with Tanzu, storage policies are essential for defining the characteristics of storage resources used by Kubernetes workloads. For high performance and fault tolerance, a RAID 1 storage policy with mirroring is most appropriate. Applying this policy to the Supervisor Cluster ensures all namespaces and workloads inherit the desired storage characteristics.
- A. Incorrect.
RAID 5 offers storage efficiency but does not provide the high fault tolerance and performance required for Tanzu Kubernetes Grid Service persistent volumes. It is not suitable for this scenario.
- B. Correct.
RAID 1 provides mirroring, ensuring both high performance and fault tolerance, which are critical for the persistent volumes required by Tanzu Kubernetes Grid Service. Applying this policy to the Supervisor Cluster ensures the desired behavior.
- C. Incorrect.
The default vSAN storage policy may not be optimized for high performance and fault tolerance. Customizing a policy is necessary to meet the specific requirements of the scenario.
- D. Incorrect.
Manually assigning datastores bypasses the use of vSphere storage policies, which are essential for applying consistent and scalable storage configurations across clusters.
