SIMULATION
You can switch the cluster/configuration context using the following command:
[desk@cli] $ kubectl config use-context dev
A default-deny NetworkPolicy avoid to accidentally expose a Pod in a namespace that doesn't have any other NetworkPolicy defined.
Task: Create a new default-deny NetworkPolicy named deny-network in the namespace test for all traffic of type Ingress + Egress The new NetworkPolicy must deny all Ingress + Egress traffic in the namespace test.
Apply the newly created default-deny NetworkPolicy to all Pods running in namespace test.
You can find a skeleton manifests file at /home/cert_masters/network-policy.yaml

NEW QUESTION # 63
Given an existing Pod named nginx-pod running in the namespace test-system, fetch the service-account-name used and put the content in /candidate/KSC00124.txt Create a new Role named dev-test-role in the namespace test-system, which can perform update operations, on resources of type namespaces.

NEW QUESTION # 64
SIMULATION
Documentation
ServiceAccount, Deployment,
Projected Volumes
You must connect to the correct host . Failure to do so may
result in a zero score.
[candidate@base] $ ssh cks000033
Context
A security audit has identified a Deployment improperly handling service account tokens, which could lead to security vulnerabilities.
Task
First, modify the existing ServiceAccount stats-monitor-sa in the namespace monitoring to turn off automounting of API credentials.
Next, modify the existing Deployment stats-monitor in the namespace monitoring to inject a ServiceAccount token mounted at /var/run/secrets/kubernetes.io/serviceaccount/token.
Use a Projected Volume named token to inject the ServiceAccount token and ensure that it is mounted read-only.
The Deployment's manifest file can be found at /home/candidate/stats-monitor/deployment.yaml.
Answer:
Explanation:
See the Explanation below for complete solution
Explanation:
1) Connect to correct host
ssh cks000033
sudo -i
export KUBECONFIG=/etc/kubernetes/admin.conf
2) Patch the ServiceAccount to disable automounting
Task: turn off automounting of API credentials for stats-monitor-sa in monitoring.
kubectl -n monitoring patch sa stats-monitor-sa -p '{"automountServiceAccountToken": false}' Verify:
kubectl -n monitoring get sa stats-monitor-sa -o yaml | grep -i automount
3) Edit the Deployment manifest file
Task says to modify the manifest at:
/home/candidate/stats-monitor/deployment.yaml
vi /home/candidate/stats-monitor/deployment.yaml
4) In the Deployment, ensure it uses the ServiceAccount AND inject token via Projected Volume
4.1 Make sure Deployment uses the SA
Under:
spec: -> template: -> spec:
ensure:
serviceAccountName: stats-monitor-sa
(If it already exists, leave it; don't add extra changes beyond requirements.)
4.2 Add a projected volume named token
Under:
spec: -> template: -> spec: -> volumes:
add (or modify existing volume if present) so it is exactly:
- name: token
projected:
sources:
- serviceAccountToken:
path: token
This creates the file token inside the mounted directory, so the final path becomes:
/var/run/secrets/kubernetes.io/serviceaccount/token
4.3 Mount the projected volume read-only at the required location
Under the target container:
spec: -> template: -> spec: -> containers: -> (your container) -> volumeMounts:
Add:
- name: token
mountPath: /var/run/secrets/kubernetes.io/serviceaccount
readOnly: true
โ
This satisfies:
Projected volume name: token
Mount path: /var/run/secrets/kubernetes.io/serviceaccount/token (file inside mount) Mounted read-only
4.4 Important: Don't break default token mount behavior
Because you disabled SA automounting at the ServiceAccount level, you must explicitly mount the projected token (done above). That's the whole point of this task.
Save and exit:
:wq
5) Apply the updated Deployment
kubectl -n monitoring apply -f /home/candidate/stats-monitor/deployment.yaml Wait rollout:
kubectl -n monitoring rollout status deployment/stats-monitor
6) Verify the token file exists in the running Pod
Get a pod name:
POD=$(kubectl -n monitoring get pods -l app=stats-monitor -o jsonpath='{.items[0].metadata.name}') echo $POD Check the token file path exists:
kubectl -n monitoring exec -it $POD -- ls -l /var/run/secrets/kubernetes.io/serviceaccount/token Optional: confirm it's mounted read-only (usually shown by mount options):
kubectl -n monitoring exec -it $POD -- mount | grep /var/run/secrets/kubernetes.io/serviceaccount
โ
What the examiner checks
SA stats-monitor-sa has:
automountServiceAccountToken: false
Deployment stats-monitor mounts a projected volume named token
Token file is at:
/var/run/secrets/kubernetes.io/serviceaccount/token
Mount is readOnly: true
If label selector doesn't match (-l app=stats-monitor)
Use:
kubectl -n monitoring get pods
Then set:
POD=<paste-pod-name>
