Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q240-Q245):

NEW QUESTION # 240
What does "Continuous Integration" mean?

A. The continuous integration and testing of code changes from multiple sources manually.
B. The continuous integration of new tools to support developers in a project.
C. The continuous integration and testing of code changes from multiple sources via automation.
D. The continuous integration of changes from one environment to another.

Answer: C

Explanation:
The correct answer is B: Continuous Integration (CI) is the practice of frequently integrating code changes from multiple contributors and validating them through automated builds and tests. The "continuous" part is about doing this often (ideally many times per day) and consistently, so integration problems are detected early instead of piling up until a painful merge or release window.
Automation is essential. CI typically includes steps like compiling/building artifacts, running unit and integration tests, executing linters, checking formatting, scanning dependencies for vulnerabilities, and producing build reports. This automation creates fast feedback loops that help developers catch regressions quickly and maintain a releasable main branch.
Option A is incorrect because manual integration/testing does not scale and undermines the reliability and speed that CI is meant to provide. Option C confuses CI with deployment promotion across environments (which is more aligned with Continuous Delivery/Deployment). Option D is unrelated: adding tools can support CI, but it isn't the definition.
In cloud-native application delivery, CI is tightly coupled with containerization and Kubernetes: CI pipelines often build container images from source, run tests, scan images, sign artifacts, and push to registries. Those validated artifacts then flow into CD processes that deploy to Kubernetes using manifests, Helm, or GitOps controllers. Without CI, Kubernetes rollouts become riskier because you lack consistent validation of what you're deploying.
So, CI is best defined as automated integration and testing of code changes from multiple sources, which matches option B.

NEW QUESTION # 241
What is the primary purpose of an Ingress resource in Kubernetes?

A. To monitor the health status of application Pods.
B. To expose internal services to external web traffic.
C. To manage persistent volumes for application data.
D. To store configuration data used by applications.

Answer: B

Explanation:
An Ingress resource defines rules for routing external HTTP/HTTPS traffic into the cluster, allowing internal Services to be accessed from outside through a single entry point.

NEW QUESTION # 242
Which statement best describes the role of kubelet on a Kubernetes worker node?

A. kubelet configures networking rules on each node to handle traffic routing for Services in the cluster.
B. kubelet monitors cluster-wide resource usage and assigns Pods to the most suitable nodes for execution.
C. kubelet acts as the primary API component that stores and manages cluster state information.
D. kubelet manages the container runtime and ensures that all Pods scheduled to the node are running as expected.

Answer: D

Explanation:
The kubelet is the node-level agent responsible for interacting with the container runtime and ensuring that Pods assigned to the node are started, kept running, and reported as healthy according to their specifications.

NEW QUESTION # 243
Which of these components is part of the Kubernetes Control Plane?

A. coredns
B. kubelet
C. cloud-controller-manager
D. kube-proxy

Answer: C

NEW QUESTION # 244
You need to configure a Kubernetes cluster to use a specific DNS server. Which of the following methods can be used to achieve this?

A. Modifying the /etc/resolv.conf file on each node
B. Configuring a custom DNS service in the cluster using a Deployment and a Service
C. Setting the 'dnsPolicy' field in the Pod spec to 'ClusterFirst'
D. Setting the 'dnsConfig' field in the Pod spec with custom DNS server details
E. Using the kubelet command-line argument -cluster-dns

Answer: D,E

Explanation:
The kubelet command-line argument -cluster-dns allows you to specify a DNS server for the cluster. This will be used by all Pods in the cluster. Alternatively, you can set the 'dnsConfig' field in the Pod spec to configure custom DNS servers for individual Pods. You can provide specific DNS server addresses and search domains within the 'dnsConfig' field.
