Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q224-Q229):

NEW QUESTION # 224
Which type of Service requires manual creation of Endpoints?

Answer: C

Explanation:
A Kubernetes Service without selectors requires you to manage its backend endpoints manually, so B is correct. Normally, a Service uses a selector to match a set of Pods (by labels). Kubernetes then automatically maintains the backend list (historically Endpoints, now commonly EndpointSlice) by tracking which Pods match the selector and are Ready. This automation is one of the key reasons Services provide stable connectivity to dynamic Pods.
When you create a Service without a selector, Kubernetes has no way to know which Pods (or external IPs) should receive traffic. In that pattern, you explicitly create an Endpoints object (or EndpointSlices, depending on your approach and controller support) that maps the Service name to one or more IP:port tuples. This is commonly used to represent external services (e.g., a database running outside the cluster) while still providing a stable Kubernetes Service DNS name for in-cluster clients. Another use case is advanced migration scenarios where endpoints are controlled by custom controllers rather than label selection.
Why the other options are wrong: Service types like ClusterIP, NodePort, and LoadBalancer describe how a Service is exposed, but they do not inherently require manual endpoint management. A ClusterIP Service with selectors (D) is the standard case where endpoints are automatically created and updated. NodePort and LoadBalancer Services also typically use selectors and therefore inherit automatic endpoint management; the difference is in how traffic enters the cluster, not how backends are discovered.
Operationally, when using Services without selectors, you must ensure endpoint IPs remain correct, health is accounted for (often via external tooling), and you update endpoints when backends change. The key concept is: no selector # Kubernetes can't auto-populate endpoints # you must provide them.
=========


NEW QUESTION # 225
You need to deploy a new version of your application to Kubernetes without causing any downtime or disruption to users. What open standard would you use to facilitate this process?

Answer: A

Explanation:
Kubernetes Rolling Update allows you to deploy new versions of your application gradually- It replaces existing pods with the new version one by one, ensuring that there is always at least one pod running the previous version, minimizing downtime. This approach helps maintain the application's availability during updates-


NEW QUESTION # 226
You are developing a microservices application with multiple pods communicating over a shared network. You need to implement a mechanism that ensures only authorized pods can access specific services within the network. What Kubernetes feature can help achieve this?

Answer: A

Explanation:
NetworkPolicy is designed for network traffic control within a Kubernetes cluster It allows you to define rules that control inbound and outbound traffic for pods based on their labels, namespaces, and other criteria. This enables you to enforce access restrictions between pods and services within your application's network. PodSecurityPolicy primarily restricts security settings for pods. ServiceAccount provides identity and credentials, and ResourceQuota and LimitRange manage resource usage.


NEW QUESTION # 227
Which of these is a valid container restart policy?

Answer: C


NEW QUESTION # 228
What kubectl command is used to retrieve the resource consumption (CPU and memory) for nodes or Pods?

Answer: B


NEW QUESTION # 229
