First — You need to be there 30 mins before exam

The proctor will take variable time to inspect your room. In my case this take around 20 mins.

• Cleaning your room and make it minimal will help !
• Make sure you can show your desk, wall etc. Use laptop or long cable webcam.
• Try removing anything on the wall. In my case, there is birthday card.

Second — Context Context Context !

Exam environment is in the single VM remote desktop. They work with multiple cluster by switching the context.

So I’m so nervous about working on the wrong context → make my exam not scored.

So I add this to check it easily

alias kcc="kubectl config current-context"

# then it easy to check by
kcc

In real scenario, it might not be that easy to happen. Because when you are in the wrong context and about to use something, it might not be there then you know you are in the wrong place.

Anyway, working on the wrong context might irreversible mess up with the state and waste your time.

Third — Always learn how to test by yourself

If your are in the lab environment, it have the check answer button.

It is not the case here.

If you do something wrong, you might not get score and you don’t know it.

So you should learn how to check when it is working

Example

• Access the service with curl or deploy busybox to curl to internal network
• Check the service is up with correct configuration k describe
