Which Kubernetes and Cloud Native Associate questions should I review first?

This test does not have enough answers yet for a ranking. Start with these topics: Pod Phase & Pending, Service & Clusterip, Helm & Chart Structure.

How is this hardest-questions list ranked?

The list counts every anonymous answer to the free practice test in the last 90 days. A question needs 20 or more answers to get a rank. The order uses the lower bound of a 95% Wilson confidence interval on the miss rate, so a question with few answers does not outrank a question with many answers. When fewer than 3 questions have 20 answers, the page shows a review set without ranks.

Review question 1

Pod Phase & Pending

Kubernetes Fundamentals

Not ranked

A Pod has just been accepted by the cluster and scheduled. The kubelet on the node is still downloading the container image over the network, and no container has been set up yet. Which phase does the Pod report?

Correct answer

B. Pending, because one or more containers is not yet set up and ready to run, including the time spent downloading images

B is correct: the Pod phase is Pending while containers are not yet set up, and the documentation says this includes the time spent downloading images. A is wrong because Running requires all containers to have been created, with at least one running or starting. C is wrong because Unknown is not reported just because an image pull is in progress. D is wrong because Succeeded means all containers terminated successfully and will not be restarted.

Review question 2

Service & Clusterip

Container Orchestration

Not ranked

A team applies a Service manifest that has a selector and ports but no spec.type field. Which statement describes how this Service can be reached?

Correct answer

B. It gets a cluster-internal IP address and is reachable only from inside the cluster unless it is exposed another way.

B is correct because ClusterIP is the default Service type, and it exposes the Service on a cluster-internal IP. A is wrong because a node port is allocated only when the type is NodePort (or LoadBalancer), not for the default type. C is wrong because an external load balancer is provisioned only when the type is LoadBalancer on a cloud that supports it. D is wrong because a Service without a type receives a cluster IP; only a Service with clusterIP set to None gets no IP address.

Review question 3

Helm & Chart Structure

Cloud Native Application Delivery

Not ranked

Which part of a Helm chart supplies the default configuration values that the templates read, and that a user can override when installing?

Correct answer

B. values.yaml, which holds default values that templates read through .Values and that user-supplied values override

B is correct: values.yaml supplies the defaults, and values given by the user override them. A is wrong because Chart.yaml is the chart's metadata file, not the place for default values. C is wrong because charts/ holds dependent charts, not value files. D is wrong because templates/ holds templates that Helm combines with values to generate Kubernetes manifests.
