Exam KCNA topic 1 question 71 discussion

The correct answer is: B. kubectl explain deployment.spec.replicas Explanation: The command kubectl explain is used to provide detailed information about the fields of Kubernetes objects, including their specifications. The command kubectl explain deployment.spec.replicas specifically provides information about the replicas field within the spec of a deployment object. This is the most appropriate command for getting details about that particular field.

A. kubectl get deployment.spec.replicas: This command attempts to retrieve the value of replicas directly from the deployment resource. However, it's not a standard way to access nested fields like spec.replicas. B. kubectl explain deployment.spec.replicas: This command is used to get documentation or information about a specific field within a Kubernetes resource definition. It will provide details about what the replicas field represents within the spec of a deployment. C. kubectl describe deployment.spec.replicas: This command describes an existing resource, such as a deployment, but it does not specifically explain the meaning or purpose of a field like replicas within the spec. D. kubectl explain deployment --spec.replicas: This command is close but not entirely correct. It attempts to explain a flag --spec.replicas for the kubectl explain command, rather than directly explaining the replicas field within the spec of a deployment.
