Kubernetes Administrator (CKA) Practice Questions: Second Edition Part 4

Can we join a new node in the cluster?

K8s Control Plane shows its status as NotReady (while setting up control plane and nodes) because you have not done ___________________ yet.

Calico is a __________.

If you do not create a new namespace, K8s will create a new namespace for you. True or false?

kubeadm creates a namespace for system components called __________.

Kubernetes provides _________________ robust and self-healing without the need for administrative intervention?

Which Kubernetes cluster can tolerate a component loss and serve workloads without interruption?

When using multiple planes for high availability, you likely need to communicate with the Kubernetes API through a load balancer. Does it include clients such as kubelet instance? What is the name of plane?

Which cluster is an architecture in which the distributed data storage cluster supplied by etcd is placed on top of the cluster produced by kubeadm-managed nodes running control plane components?

Which of the following is an architecture in which the distributed data storage cluster supplied by etcd is separate from the cluster established by control plane nodes?

From a user’s perspective, which of the following for Kubernetes enables you to carry out any Kubernetes function?

Which tool allows you to quickly and easily create Kubernetes clusters?

Which of the following allows you to create a local single-node in the Kubernetes cluster automatically? Is it great for getting Kubernetes up and running quickly for development purposes?

Which of the following enables Kubernetes object templating and package management that you can use to manage your templates (known as charts)?

Which converts Docker compose files into Kubernetes objects?

Which configuration management tool allows you to manage Kubernetes object configurations and allows you to share and reuse template configurations for Kubernetes applications?

When doing maintenance, you may need to deactivate a Kubernetes node. You may accomplish this by ________________ the node. Containers currently executing on the node be gently terminated (and potentially rescheduled on another node)?

Which of the following ignores system pods on the node that cannot be destroyed?

If you have any DaemonSet pods running on the node, you likely need to use the –ignore-daemonsets flag. When draining a node, which of the following you may need?

Suppose the node remains part of the cluster. In that case, you can allow pods to run on the node again when maintenance is complete using which command?

When you are running an application in Kubernetes, you will probably, at some point, want to pass ______________ values to your applications at runtime to control how they behave?

Which of the following stores data in the form of a key-value map and can be passed to your container applications?

Which of the following are similar to ConfigMaps, but are designed to store sensitive data more securely, such as passwords or API keys?

You can pass ConfigMap and Secret data to your containers as ______, which are visible to your container process at runtime?

ConfigMaps and Secrets configuration data may also be supplied to containers in the form of ________. It causes the configuration data to appear in files available to the container file system.

Which of the following allows you to define several resources you expect a container to use, such as CPU or memory?

Which of the following provides a way for you to limit the number of resources your containers can use?

Which value indicates whether or not the container is operating? Does the kubelet terminate the container and subject it to the restart policy if that probe fails?

Which of the following indicates whether the container’s application is running? All other probes are blocked until it succeeds if that probe is supplied. If that probe fails, the kubelet terminates the container and subjects it to the restart policy.

Which of the following indicates if the container is prepared to respond to queries? If that probe fails, the endpoints controller removes the Pod’s IP address from all Services that match the Pod’s endpoints.

Kubernetes can automatically restart containers when they fail. Which allows you to customize this behavior by defining when you want a pod’s containers to be automatically restarted?

Which is the default restart policy in Kubernetes? With this policy, containers always are restarted if they stop, even if completed successfully.

Which restart policy restarts containers only if the container process exits with an error code or the container is determined to be unhealthy by a liveness probe?

Which restart policy causes the pod’s containers to never be restarted, even if the container exits or a liveness probe fails?

Which of the following are containers that run once during the startup process?
Note: A pod can have any number of which, and they each run once to complete.
