NEW QUESTION # 55
You can switch the cluster/configuration context using the following command:
[desk@cli] $ kubectl config use-context qa
Context:
A pod fails to run because of an incorrectly specified ServiceAccount
Task:
Create a new service account named backend-qa in an existing namespace qa, which must not have access to any secret.
Edit the frontend pod yaml to use backend-qa service account
Note: You can find the frontend pod yaml at /home/cert_masters/frontend-pod.yaml
Answer:
Explanation:
[desk@cli] $ k create sa backend-qa -n qa
sa/backend-qa created
[desk@cli] $ k get role,rolebinding -n qa
No resources found in qa namespace.
[desk@cli] $ k create role backend -n qa --resource pods,namespaces,configmaps --verb list
# No access to secret
[desk@cli] $ k create rolebinding backend -n qa --role backend --serviceaccount qa:backend-qa
[desk@cli] $ vim /home/cert_masters/frontend-pod.yaml
apiVersion: v1
kind: Pod
metadata:
name: frontend
spec:
serviceAccountName: backend-qa # Add this
image: nginx

[desk@cli] $ k apply -f /home/cert_masters/frontend-pod.yaml
pod created
[desk@cli] $ k create sa backend-qa -n qa
serviceaccount/backend-qa created
[desk@cli] $ k get role,rolebinding -n qa
No resources found in qa namespace.
[desk@cli] $ k create role backend -n qa --resource pods,namespaces,configmaps --verb list role.rbac.authorization.k8s.io/backend created

NEW QUESTION # 56
You're working with a Kubernetes cluster where you need to enforce a secure supply chain. You have a Kubernetes deployment that utilizes a container image from a specific registry. How would you configure your Kubernetes cluster to only allow images from this registry to be used in deployments?
Answer:
Explanation:
Solution (Step by Step) :
1. Create a PodSecurityPolicy (PSP):
- A PSP is a policy that enforces security restrictions on pods. We will use it to restrict image pulls to a specific registry.
- create a PSP YAML file.
2. Define Allowed Registries: - Within the 'spec' of your PSP, create a field 'seLinux' and then define the allowed registries within the 'seLinux' field. - Example:
3. Apply the PSP: - Apply the PSP to your cluster using kubectl apply -f restricted-registry-psp.yaml' 4. Create a Service Account: - Create a service account that will be allowed to run pods with this PSP:
5. Bind the PSP to the Service Account: - Add the 'securityContext' field to your deployment and specify the PSP you just created:
- Apply the deployment: bash kubectl apply -f deploymentyaml - Now, the deployment will only be able to pull images from the specified registry-
NEW QUESTION # 57
You are running a critical application within a Kubernetes cluster, and you need to implement a robust security posture to prevent unauthorized access and protect sensitive dat
a. The application uses a PostgreSQL database, and you want to enforce strong access control for the database while ensuring the database pods are not directly accessible from the internet Describe how you would implement the following security measures using Kubernetes resources and tools:
1. Network Policy: Create a network policy that restricts access to the PostgreSQL database pods to only the application pods.
2. Pod Security Policies: Enforce strong security policies for the database pods, including restrictions on capabilities, resource usage, and privileged
access.
3. Secret Management Securely store the database credentials using a Kubernetes secret, ensuring that only authorized application pods can access
them.
4. Logging and Monitoring: Implement logging and monitoring for the PostgreSQL database pods to detect any potential security threats or anomalies.
Answer:
Explanation:
Solution (Step by Step) :
1. Network Policy:
1. Create a network policy:
2. Apply the network policy: basn kubectl apply -f postgres-access-policy.yaml 2. Pod Security Policies: 1. Create a Pod Security Policy:
2. Apply the Pod Security Policy: bash kubectl apply -f postgres-psp.yaml 3. Apply the PSP to the PostgreSQL deployment:
3. Secret Management: 1. Create a secret for the database credentials: bash kubectl create secret generic postgres-credentials --from-literal--username=postgres --from-literal-password-your-password 2. Mount the secret in the PostgreSQL pod:
4. Logging and Monitoring: 1. Configure logging for the PostgreSQL pods: - Use a logging solution like Fluentd or EFK (Elasticsearch, Fluentd, Kibana) to collect logs from the PostgreSQL pods. - Configure the logging solution to capture both application logs and database logs. 2. Implement monitoring: - Use Prometheus and Grafana to monitor the PostgreSQL pods for metrics like CPIJ usage, memory consumption, and database queries. - Set up alerts for any unusual activity or performance degradation- Important Notes: - Replace 'your-namespace' with your actual namespace. - Replace 'your-application' with the name of your application- - Ensure that the service account 'postgres-sa' has access to the secret. - You may need to adjust the PSP based on your specific security requirements. This approach provides a comprehensive security posture for your PostgreSQL database within a Kubernetes cluster, ensuring data integrity and access control while providing the necessary monitoring and logging for early threat detection.
NEW QUESTION # 58
SIMULATION
Documentation Deployments, Pods, Falco
You must connect to the correct host . Failure to do so may result in a zero score.
[candidate@base] $ ssh cks000026
Context
A Pod is misbehaving and poses a security threat to the system.
Task
One of the Pods belonging to the application ollama is misbehaving. It is directly accessing the system's memory reading from the sensitive file /dev/mem.
First, identify the misbehaving Pod accessing /dev/mem.
The cluster uses the Docker Engine as its container runtime . If needed, use the docker command to troubleshoot running containers.
Next, identify the Deployment managing the misbehaving Pod and scale it to zero replicas.
Do not modify the Deployment except for scaling it down.
Do not modify any other Deployments .
Do not delete any Deployments.
Answer:
Explanation:
See the Explanation below for complete solution
Explanation:
1) Connect to the correct host
ssh cks000026
sudo -i
2) Identify the misbehaving Pod accessing /dev/mem
This task hints Falco is available → use it first (fast + intended).
2.1 Check Falco logs for /dev/mem access
journalctl -u falco | grep dev/mem
If Falco runs as a pod instead of systemd:
kubectl -n falco logs -l app=falco | grep dev/mem
2.2 Identify the Pod name
From the Falco output, you will see something like:
Pod=ollama-xxxxx Namespace=default File=/dev/mem
Note the exact Pod name (example: ollama-7c9d6f7b6d-abcde)
3) (If Falco logs are unclear) Confirm using Docker runtime
Because the cluster uses Docker, verify which container is accessing /dev/mem.
3.1 List running containers
docker ps
3.2 Inspect suspicious container
(Find container related to ollama)
docker inspect <container_id> | grep ollama
You should confirm it maps to the same Pod you saw in Falco.
4) Identify the Deployment managing the misbehaving Pod
4.1 Get Pod details
kubectl get pod <MISBEHAVING_POD_NAME> -o wide
4.2 Find owning Deployment
kubectl get pod <MISBEHAVING_POD_NAME> -o jsonpath='{.metadata.ownerReference[0].name}' This will output something like:
ollama
That is the Deployment name
5) Scale ONLY that Deployment to zero replicas
Do not edit, delete, or touch anything else
kubectl scale deployment ollama --replicas=0
6) Verify the Pod is terminated
kubectl get pods | grep ollama
Expected: no running Pods
Also confirm replicas:
kubectl get deployment ollama
Replicas should show:
0/0
