Which two statements are correct about Kubernetes resources? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: A, B

Kubernetes resources are the building blocks of Kubernetes clusters, enabling the deployment and management of applications. Let's analyze each statement:

A . A ClusterIP type service can only be accessed within a Kubernetes cluster.

Correct:

A ClusterIP service is the default type of Kubernetes service. It exposes the service internally within the cluster, assigning it a virtual IP address that is accessible only to other pods or services within the same cluster. External access is not possible with this service type.

B . A daemonSet ensures that a replica of a pod is running on all nodes.

Correct:

A daemonSet ensures that a copy of a specific pod is running on every node in the cluster (or a subset of nodes if specified). This is commonly used for system-level tasks like logging agents or monitoring tools that need to run on all nodes.

C . A deploymentConfig is a Kubernetes resource.

Incorrect:

deploymentConfig is a concept specific to OpenShift, not standard Kubernetes. In Kubernetes, the equivalent resource is called a Deployment , which manages the desired state of pods and ReplicaSets.

I heard Kubernetes is so complicated, they have to make the certification exams as confusing as possible. If you can't handle a few trick questions, how can you manage a real cluster?

D is clearly the other correct answer. NodePort services are a great way to expose apps to the outside world, even if they don't use a cloud load balancer.

That's correct. ClusterIP services are for internal communication within the Kubernetes cluster.

Yes, NodePort services expose the service externally through each node's IP address.

I'm pretty sure A is also correct. ClusterIP services are only accessible within the cluster, which is perfect for internal-facing components.

Wait, isn't C a trick question? I'm pretty sure DeploymentConfig is an OpenShift thing, not a vanilla Kubernetes resource.

I'm not sure about statement D. Can someone explain why NodePort service does not use a cloud provider load balancer?

B is definitely correct. DaemonSets ensure that a pod is running on every node in the cluster. That's super useful for things like monitoring agents and network plugins.

I agree with you, Kanisha. I also believe statement B is correct as daemonSet ensures a replica of a pod on all nodes.

I think statement A is correct because ClusterIP is for internal communication only.
