Ultimate Certified Kubernetes Administrator (CKA) Mock Exam Series

Find the pod that consumes the most CPU and store the result to the file /opt/high_cpu_pod in the following format cluster_name,namespace,pod_name.

The pod could be in any namespace in any of the clusters that are currently configured on the student-node.

data stored in /opt/high_cpu_pod?

why it was marked Incorrect for me ?

I think you have stored static solution for verification.

Kindly verify it, If anything wrong at my end please let me know.

Thank you,

Hi Tej,

Just let me know once its fixed.

Hi @swapnilbkc,
Sorry for the late reply. The team pushed some fixes. Please try again.

Regards,

I just noticed that the frontend-stable-cka05-arch consuming maximum CPU, not kube-apiserver-cluster1-controlplane.
