Passed CKAD

Passed my Certified Kubernetes Application Developer exam this week. I started studying for it in early January, but I paused a couple of weeks later, as work and personal stuff left little time for much else. I studied for a couple of weeks before the exam.

Recommendations for anyone else planning to take the exam:

1. Familiarize yourself with the docs pages

2. Bookmark docs pages of resources in the exam (you are allowed to)

3. Take killer.sh and do it 3-4 times (timing yourself after the first 2)

4. Put some useful aliases/commands on your exam terminal - I used:

• alias kn='kubectl config set-context --current --namespace '

• alias k='kubectl'

• alias kgpods='kubectl get pods'

• export do="--dry-run=client -o yaml"

• and ~/.vimrc lines: set tabstop=2 and set expandtab

5. Pay attention to namespaces and cluster context in each question

6. On your first pass of the questions don’t even read the ones scoring <5%. Read the rest and attempt them if you think you can solve them. On the second pass, read every question scoring <5% and solve them if you can. On the third pass, you should have any questions you will need to think deeper - prioritize the easier-looking ones and those scoring higher.

7. You need to be fast, but try to double check your every answer.

On to CKA, probably :)
