You are using a configMapGenerator to create a ConfigMap from a file. You notice that the generated ConfigMap has a hash suffix (e.g., 'my-config-abc123'). You want to reference this ConfigMap in a Deployment. How should you reference it?

Use the full hashed name 'my-config-abc123' in the Deployment.

Disable the hash suffix by setting 'disableNameSuffixHash: true' and reference 'my-config'.

You cannot reference a generated ConfigMap in a Deployment; you must create it manually.

Use the name 'my-config' in the Deployment's configMapRef, and Kustomize will update it to the hashed name.

In a typical Kustomize directory structure, what is the relationship between a base and an overlay?

The overlay replaces the base in the final output

The overlay references the base and applies modifications on top of it

The base references the overlay to inherit environment-specific settings

The base and overlay are independent and do not reference each other

What is the primary purpose of Kustomize in Kubernetes?

To replace Helm as the only package manager for Kubernetes

To store Kubernetes secrets in an encrypted format

To generate random configuration values for testing purposes

To manage Kubernetes resources declaratively without using templates

You are deploying the same kustomization to two different clusters. To avoid resource name conflicts, you want all resources in one cluster to have the prefix 'blue-' and in the other 'green-'. You also want to deploy them to different namespaces. What is the best way to achieve this?

Use kubectl apply with the --namespace flag and manually rename resources in each cluster.

Use a JSON patch to change the metadata.name and metadata.namespace of each resource.

Create two overlays, each with a namePrefix and namespace field set appropriately.

Set the namePrefix and namespace fields in the base kustomization.
