Linux Foundation Certified Kubernetes Security Specialist (CKS) Sample Questions:
SIMULATION
Create a new ServiceAccount named backend-sa in the existing namespace default, which has the capability to list the pods inside the namespace default.
Create a new Pod named backend-pod in the namespace default, mount the newly created sa backend-sa to the pod, and Verify that the pod is able to list pods.
Ensure that the Pod is running.
Correct Answer:
A service account provides an identity for processes that run in a Pod.
When you (a human) access the cluster (for example, using kubectl), you are authenticated by the apiserver as a particular User Account (currently this is usually admin, unless your cluster administrator has customized your cluster). Processes in containers inside pods can also contact the apiserver. When they do, they are authenticated as a particular Service Account (for example, default).
When you create a pod, if you do not specify a service account, it is automatically assigned the default service account in the same namespace. If you get the raw json or yaml for a pod you have created (for example, kubectl get pods/<podname> -o yaml), you can see the spec.serviceAccountName field has been automatically set.
You can access the API from inside a pod using automatically mounted service account credentials, as described in Accessing the Cluster. The API permissions of the service account depend on the authorization plugin and policy in use.
In version 1.6+, you can opt out of automounting API credentials for a service account by setting automountServiceAccountToken: false on the service account:
apiVersion: v1
kind: ServiceAccount
metadata:
name: build-robot
automountServiceAccountToken: false
...
In version 1.6+, you can also opt out of automounting API credentials for a particular pod:
apiVersion: v1
kind: Pod
metadata:
name: my-pod
spec:
serviceAccountName: build-robot
automountServiceAccountToken: false
...
The pod spec takes precedence over the service account if both specify a automountServiceAccountToken value.
SIMULATION

Documentation Deployments, Pods, bom Command Help bom-help
You must connect to the correct host. Failure to do so may result in a zero score.
[candidate@base] $ ssh cks000035
Task
The alpine Deployment in the alpine namespace has three containers that run different versions of the alpine image.
First, find out which version of the alpine image contains the libcrypto3 package at version 3.1.4-r5.
Next, use the pre-installed bom tool to create an SPDX document for the identified image version at /home/candidate/alpine.spdx.
You can find the bom tool documentation at bom.
Finally, update the alpine Deployment and remove the container that uses the idenfied image version.
The Deployment's manifest file can be found at /home/candidate/alpine-deployment.yaml.
Do not modify any other containers of the Deployment.
Correct Answer:
See the Explanation below for complete solution
Explanation:
1) Connect to the correct host
ssh cks000035
sudo -i
export KUBECONFIG=/etc/kubernetes/admin.conf
2) List the 3 container names + images in the Deployment
kubectl -n alpine get deploy alpine -o jsonpath='{range .spec.template.spec.containers[*]}{.name}{"\t"}{.image}{"\n"}{end}' You'll get 3 lines like:
c1 alpine:3.xx
c2 alpine:3.yy
c3 alpine:3.zz
3) Identify which alpine image has libcrypto3 at 3.1.4-r5
Fastest reliable method (since it's Alpine, just query apk inside each image):
Run these one-by-one for each image you saw in step 2:
docker run --rm <ALPINE_IMAGE_1> sh -c 'apk info -v libcrypto3 2>/dev/null | head -n1' docker run --rm <ALPINE_IMAGE_2> sh -c 'apk info -v libcrypto3 2>/dev/null | head -n1' docker run --rm <ALPINE_IMAGE_3> sh -c 'apk info -v libcrypto3 2>/dev/null | head -n1'
✅ The correct image is the one that prints exactly:
libcrypto3-3.1.4-r5
Note that full image tag, e.g.:
IMG=alpine:3.xx
4) Create SPDX document with bom for that identified image
(Use the identified image from step 3.)
bom generate --image $IMG --format spdx --output /home/candidate/alpine.spdx Verify file exists:
ls -l /home/candidate/alpine.spdx
5) Remove ONLY the container that uses that image version
The manifest to edit is:
vi /home/candidate/alpine-deployment.yaml
In the spec.template.spec.containers: list, find the container entry whose image: equals the identified $IMG, and delete that one container block only (name/image/ports/etc for that container).
Save:
:wq
6) Apply the updated Deployment (do not change other containers)
kubectl apply -f /home/candidate/alpine-deployment.yaml
Wait rollout:
kubectl -n alpine rollout status deployment/alpine
7) Verify only 2 containers remain
kubectl -n alpine get deploy alpine -o jsonpath='{range .spec.template.spec.containers[*]}{.name}{"\t"}{.image}{"\n"}{end}' You should now see 2 lines, and the $IMG line should be gone.
If bom generate ... errors (quick fix)
Check exact syntax on that system:
bom --help
bom generate --help
Then rerun with the flags it expects, keeping:
image = $IMG
output = /home/candidate/alpine.spdx
format = spdx
