Free Linux Foundation CKA Exam Dumps Questions & Answers

Task Summary
You are managing a WordPress Deployment in namespace relative-fawn.
* Deployment has 3 replicas.
* Pods are not starting due to high resource requests.
* Your job:# Adjust CPU and memory requests so that all 3 pods evenly split the node's capacity.
Step-by-Step Solution
1## SSH into the correct host
bash
CopyEdit
ssh cka000058
# Skipping this will result in a zero score.
2## Check node resource capacity
You need to know the node's CPU and memory resources.
bash
CopyEdit
kubectl describe node | grep -A5 "Capacity"
Example output:
yaml
CopyEdit
Capacity:
cpu: 3
memory: 3Gi
Let's assume the node has:
* 3 CPUs
* 3Gi memory
So for 3 pods, divide evenly:
* CPU request per pod: 1
* Memory request per pod: 1Gi
## In the actual exam, check real values and divide accordingly. If the node has 4 CPUs and 8Gi, you'd allocate ~1.33 CPUs and ~2.66Gi RAM per pod (rounded reasonably).
3## Edit the Deployment
Edit the WordPress deployment in the relative-fawn namespace:
kubectl edit deployment wordpress -n relative-fawn
Look for the resources section under spec.template.spec.containers like this:
resources:
requests:
cpu: "1"
memory: "1Gi"
If the section doesn't exist, add it manually.
Save and exit the editor (:wq if using vi).
4## Confirm changes
Wait a few seconds, then check:
kubectl get pods -n relative-fawn
Ensure all 3 pods are in Running state.
You can also describe a pod to confirm resource requests are set:
kubectl describe pod <pod-name> -n relative-fawn | grep -A5 "Containers" ssh cka000058 kubectl describe node | grep -A5 "Capacity" kubectl edit deployment wordpress -n relative-fawn
# Set CPU: 1, Memory: 1Gi (or according to node capacity)
kubectl get pods -n relative-fawn
