The Kubernetes Exam Your Daily kubectl History Already Chose

Every syllabus comparison of the CKA and the CKAD tells you the same thing: one is broader, one is narrower, both are two hours, both need 66%, both are 100% hands-on. None of that actually tells you which one to sit. What tells you is far simpler and sitting right there in your shell history: the commands you already run against a cluster every week.

Instead of another domain-by-domain breakdown, run this 5-command self-test. It takes less time than reading a syllabus PDF.

The self-test

Open your shell history (history | grep kubectl, or just think back to last week) and check off which of these five you actually typed, not which ones you know exist.

# 1. Node-level operations
kubectl drain node-3 --ignore-daemonsets
kubectl cordon node-3

# 2. Cluster state backup/restore
etcdctl snapshot save /backup/etcd-snap.db

# 3. Cluster-wide access control
kubectl create rolebinding dev-binding --role=dev-role --user=jane -n team-a

# 4. Rolling out an application change
kubectl set image deployment/api api=myorg/api:v2.3
kubectl rollout status deployment/api

# 5. Application-level debugging
kubectl describe pod api-7d9f8 | grep -A5 Events
kubectl logs api-7d9f8 --previous

Commands 1 through 3 are cluster-owner work: you are responsible for the machine underneath the workloads, not just the workloads. Commands 4 and 5 are the daily reality of shipping and debugging an application on infrastructure someone else keeps running.

Scoring it

If your real, honest history leans 1-2-3, that is a CKA profile. The exam's four domains, cluster architecture, workloads and scheduling, services and networking, and troubleshooting, are all written from the point of view of the person who owns the node, not just the pod running on it.

If your history leans 4-5, that is a CKAD profile. Its domains, application design, deployment configuration, observability, and application environment, assume the cluster is a given and test how fast and correctly you can ship and fix what runs on top of it.

Most engineers do not sit at either extreme. If you are close to even, the tiebreaker is not preference, it is the market: over 80% of Kubernetes job postings in Pakistan in 2026 name the CKA specifically, even for roles that lean closer to application deployment day-to-day. When the self-test is a genuine toss-up, that market data is the deciding vote, not a coin flip.

Why this beats a syllabus comparison

A syllabus tells you what is testable. It does not tell you what is natural. Two engineers can read the identical CKA domain list and one will find etcd restore drills intuitive because they have broken a cluster and fixed it before, while the other will find the same drills exhausting because their daily work never touches that layer. Preparation time roughly triples when you are studying a domain that is not already close to your muscle memory. The self-test above is really a proxy for that: it tells you which exam you can prepare for in 12 weeks without fighting your own instincts the whole way.

The certification is one line item, not the whole plan

Whichever exam the self-test points you to, it is worth remembering that a certification is a single, well-defined credential inside a much longer career arc, not a career plan by itself. If you are mapping out where a Kubernetes credential actually sits relative to the rest of the skill stack, from Linux fundamentals through to a lead or architect title, the complete DevOps Career Guide for Pakistan lays out the full seven-to-ten-year path and exactly where a CKA or CKAD pays off most along it.

I put the full comparison in one place: the 2026 PKR pricing for both exams, role-based recommendations, and the salary premium each certification carries in the Pakistani market, over here: Kubernetes Certification Pakistan: CKA vs CKAD.
