CKAD mock exam 5, Q 7

The question asks to update helm repo, and then upgrade a nginx release to be above 13.2.9.
At the beginning I used “helm upgrade” command without setting --version, which upgraded to latest nginx version 18.3.2, that is already above 13.2.9 as per question requirement, but the grader didn’t accept my answer

When I used --version option to set to the next version 13.2.10 , the answer got accepted.

is there a reason why latest nginx chart is not accepted

I don’t really have much direct knowledge of how the graders are coded. It’s possible that the grader doesn’t code that particular path; I’m not sure what default behavior is when --version is not supplied, and we may not be testing the default behavior.
