Questions

Question 1: Exam Domains

[30 seconds]

What is the largest weighted domain on the CKAD exam, and what percentage is it worth?

Answer

Application Environment, Configuration and Security at 25%.

This includes ConfigMaps, Secrets, ServiceAccounts, resource requirements, SecurityContexts, and CRDs.

---

Question 2: Multi-Container Patterns

[30 seconds]

Name the three multi-container pod patterns you must know for CKAD.

Answer

1. Init containers - Run before main containers, must complete successfully
2. Sidecar - Run alongside main container for the pod’s lifetime
3. Ambassador - Proxy connections to external services

---

Question 3: Imperative Command

[1 minute]

Write the single command to create a Job named process-data using busybox that echoes “Processing complete”.

Answer

k create job process-data --image=busybox -- echo "Processing complete"

---

Question 4: YAML Generation

[1 minute]

Write the command to generate a deployment YAML file for web-app with nginx image and 3 replicas, without actually creating it.

Answer

k create deploy web-app --image=nginx --replicas=3 --dry-run=client -o yaml > web-app.yaml

Key elements:

• --dry-run=client prevents creation
• -o yaml outputs YAML format

---

Question 5: Pattern Recognition

[30 seconds]

Your application needs to wait for a database service to be available before starting. Which multi-container pattern should you use?

Answer

Init container

Init containers run before the main container starts and must complete successfully. They’re perfect for:

• Waiting for dependencies
• Downloading/generating config
• Running database migrations

---

Question 6: Context Management

[30 seconds]

Write the command to switch to a context named ckad-cluster and set the default namespace to dev.

Answer

k config use-context ckad-cluster
k config set-context --current --namespace=dev

Or combine:

k config use-context ckad-cluster && k config set-context --current --namespace=dev

---

Question 7: Probe Types

[30 seconds]

What are the three probe types in Kubernetes, and what happens when each fails?

Answer

1. Liveness probe - Container is restarted when it fails
2. Readiness probe - Pod is removed from Service endpoints when it fails
3. Startup probe - Container is killed and restarts when it fails (during startup)

---

Question 8: JSONPath

[1 minute]

Write the command to extract just the image names from all containers in a pod named multi-app.

Answer

k get pod multi-app -o jsonpath='{.spec.containers[*].image}'

Or for one per line:

k get pod multi-app -o jsonpath='{range .spec.containers[*]}{.image}{"\n"}{end}'

---

Question 9: CronJob Schedule

[30 seconds]

What cron schedule expression runs a job at 2:30 AM every day?

Answer

30 2 * * *

Format: minute hour day-of-month month day-of-week

• 30 = minute 30
• 2 = hour 2 (2 AM)
• • = every day of month
• • = every month
• • = every day of week

---

Question 10: Three-Pass Strategy

[30 seconds]

In the three-pass exam strategy, what types of tasks should you tackle in Pass 1?

Answer

Quick wins - tasks that take 1-3 minutes:

• Create pod/deployment/service (imperative commands)
• Add labels, annotations
• Expose a deployment
• Simple ConfigMap/Secret creation

Secure easy points first before tackling complex questions.
