+\* *passing the CKA is a requirement before passing the CKS*
+
+If you pass all those certifications, you become a [Kubestronaut](https://www.cncf.io/training/kubestronaut/).
+
+## Expectation for the CKA
+---
+
+The following table summarizes the distribution of the CKA questions across 5 main subjects.
+
+| Subject                                            |  %  |
+|----------------------------------------------------|-----|
+| Cluster Architecture, Installation & Configuration | 25% |
+| Workloads & Scheduling                             | 15% |
+| Services & Networking                              | 20% |
+| Storage                                            | 10% |
+| Troubleshooting                                    | 30% |
+
+## CKA Environment
+---
+
+The CKA is a 2h exam. It contains 15/20 questions and requires at least 66% correct answers. This exam is remotely proctored, so you can take it from home (or any other quiet location) at a time that best suits your schedule.
+
+Before launching the exam, which you do via your [Linux Foundation Training Portal](https://trainingportal.linuxfoundation.org/access/saml/login), you need to perform a couple of prerequisites including making sure the PSI Browser works correctly on your environment. This browser gives you access to the remote Desktop you'll use during the exam.

+
+## Tips & tricks
+---
+
+### Tools
+
+Make sure you have a basic knowledge of
+
+- **vim**
+- **openssl**
+
+```bash
+# Visualize the content of a certificate
+openssl x509 -in cert.crt -noout -text
+```
+
+- **systemd / systemctl / journalctl**
+
+```bash
+# Restart kubelet
+systemctl restart kubelet
+
+# Check kubelet logs
+journalctl -u kubelet
+```
+
+### Aliases
+
+Defining a couple of aliases at the very beginning of the examination could save time.
+
+```bash
+alias k=kubectl
+export dr="--dry-run=client -o yaml"
+export fd="--grace-period=0 --force"
+```
+
+### Imperative commands
+
+Don't create specifications manually, instead use `--dry-run=client -o yaml` as in these examples.
+
+```bash
+k run nginx --image=nginx:1.20 --dry-run=client -o yaml > pod.yaml
+k create deploy www --image=nginx:1.20 --replicas=3 --dry-run=client -o yaml > deploy.yaml
+k create role create-pod --verb=create --resource=pods --dry-run=client -o yaml > role.yaml
+```
+
+Quickly change the current Namespace.
+
+```bash
+k config set-context --current --namespace=dev
+```
+
+Don't wait for the grace period to get rid of a Pod.
+
+```bash
+k delete po nginx --force --grace-period=0
+```
+
+### Reference guide
+
+The [Kubectl quick reference guide](https://kubernetes.io/docs/reference/kubectl/quick-reference/) is a must-read.
+
+### Access to exam simulator
+
+Registering for the CKA gives you access to two sessions of the official Exam simulator. I highly recommend using these sessions once you're almost ready.
