2V0-71.23 Question 186
Single answerYour organization has deployed Tanzu Kubernetes Grid (TKG) in a production environment. The operations team notices that one of the Kubernetes clusters is not scaling properly when workloads increase. Upon investigation, you find that the cluster’s resource pool limits are being reached in the underlying vSphere infrastructure. What is the most appropriate action to resolve this issue?
- A
Increase the resource pool limits for the affected cluster in vSphere.
- B
Recreate the cluster with a larger node size using the Tanzu CLI.
- C
Scale out the cluster by increasing the number of worker nodes using the Tanzu CLI.
- D
Migrate the workloads to another cluster that has more available resources.
Show answer and explanation
Correct answer: A
Explanation
The issue arises because the resource pool limits in vSphere are restricting the cluster's ability to scale properly. By increasing these limits, the cluster can access more resources, enabling it to handle the increased workload. This approach avoids downtime and is more efficient than recreating or migrating the cluster.
- A. Correct.
Increasing the resource pool limits in vSphere allows the cluster to access more CPU and memory, resolving the issue without recreating or migrating the cluster.
- B. Incorrect.
Recreating the cluster with a larger node size would require downtime and is not necessary if the issue is related to resource pool limits in vSphere.
- C. Incorrect.
Scaling out the cluster by adding more worker nodes will not resolve the issue if the resource pool limits in vSphere are already being exceeded.
- D. Incorrect.
Migrating workloads to another cluster is not the most appropriate action in this scenario because the issue can be resolved by addressing the resource pool limits in vSphere.
