Can you pls provide a better explaination of Question 10 of Mock exam 4 of ckad.
I am not able to understand the solution from the one provided, also it does not contain the output whic I actually get while working.

I guess my question is:

  1. What did you expect?
  2. What did you get?

I did find that running k describe on the ingress controller pod did give me a different error than what was the underlying problem – it complains about a missing secret (which is not actually missing), and does not mention the problem with the error handler service, which is misspecified in the deployment. The solution, though, does work – fixing where the default error service is and fixing the ingress’ paths does fix the problem.
