A heads up -
The final question (#9) on Practice Exam 3 for scaling nginx-deploy to 3 replicas provided me a Correct score on the first attempt after trying “k scale deployment nginx-deploy --replicas=3” despite NOT actually fixing the underlying issue as intended - the number of replicas had not updated to 3.
The condition for checking this question should be reviewed and updated to not give a false correct for others attempting this mock exam.
