NEW QUESTION # 49
You have a Kubernetes cluster running a critical application. To enhance security, you need to implement a NetworkPolicy that restricts ingress traffic to your application pods only from specific allowed IP addresses and ports. Furthermore, you want to allow egress traffic to all external services.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Allowed IP Addresses and Pons:
- Identify tne specific IP addresses and ports from whiCh you want to allow ingress traffic. For example, let'S say you want to allow traffic from
192.168.1.10 on port 8080.
2. Create the NetworkPolicy YAML:
- Create a NetworkPolicy YAML file named 'ingress-restriction.yamr with the following contents:

3. Apply the NetworkPolicy: - Apply the NetworkPoliCY YAML file using kubectl apply -f ingress-restriction.yamr 4. Test the NetworkPolicy: - Try to access the pods running your critical application from other IP addresses or ports outside of the allowed ones. This should result in connection Failures. - Attempt to access external services from the pods. This should succeed as egress traffic is allowed.


NEW QUESTION # 50
You need to configure a Kubernetes deployment to use a secret stored in a different namespace. How can you access the secret in a different namespace, and how can you mount it as a file in your deployment's container?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Ensure Access to the Secret:
- The service account used by your deployment needs to have read access to the secret in the other namespace. This can be done using a Role and RoleBinding. If the service account already has access, skip to step 2.
- Create a role in the secret's namespace:

- Create a RoleBinding in the secret's namespace:

- Apply the Role and RoleBinding using: bash kubectl apply -f role-yaml kubectl apply -f rolebinding.yaml 2. Modify your Deployment - Update your Deployment YAML file to mount the secret as a file, specifying the namespace:

- Replace 'my-secret with the actual name of the secret and 'secret-namespace with the namespace where the secret is stored. 3. Apply the Updated Deployment: - Apply the updated deployment using: bash kubectl apply -f my-deployment.yaml 4. Access Secret Data: - The secret's data is now mounted in the container at the specified 'mountPatm. You can access the secret's data using the mounted file.]


NEW QUESTION # 51
You have a microservice application that is deployed as a Deployment. You want to implement a mechanism to handle temporary network issues or other transient failures that may occur during the application's communication with external services. Explain how you can use readiness probes and liveness probes in combination with a restart policy to address these failures.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Readiness Probes:
- Add a 'readinessProbe' to the container spec of your application pods.
- The probe should check the health and readiness of the application to receive incoming requests.
- This probe should be executed periodically.
- If the probe fails, the pod will be considered not ready and won't receive traffic.
- Example using a TCP socket check:

2. Define Liveness Probes: - Add a 'livenessProbe' to the container spec of your application pods- - This probe should check the health of the application pod itself. - It should be executed periodically to detect issues that might not affect readiness but indicate a problem with the application. - If the liveness probe fails for a specified number of consecutive attempts, the pod will be restarted. - Example using a HTTP endpoint cneck:

3. Set Restart Policy: - Ensure that the restart policy for the pod is set to 'Always' (the default) to automatically restart the pod upon failure detected by the liveness probe. 4. Implement Health Check Endpoints: - Implement the health check endpoints within your application (e.g., ' Ihealth' for the liveness probe, a simple TCP connection for the readiness probe) to allow probes to assess the nealth of the application and its dependencies. 5. Verify and Monitor: - Deploy the updated Deployment and simulate network failures or other transient issues. - Monitor the pods' health and observe that they are automatically restarted and marked as not ready when necessary, ensuring continued application availability despite temporary disruptions.


NEW QUESTION # 52
Exhibit:

Task
You have rolled out a new pod to your infrastructure and now you need to allow it to communicate with the web and storage pods but nothing else. Given the running pod kdsn00201 -newpod edit it to use a network policy that will allow it to send and receive traffic only to and from the web and storage pods.

  • A. Pending

Answer: A
