What are the differences between kubectl apply and kubectl create?

This KCNA practice question tests your understanding of kubernetes fundamentals. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Which TWO of the following are correct about the 'kubectl apply' command compared to 'kubectl create'? (Select exactly two.)

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

kubectl apply can accept a directory of YAML files with -f

Option D is correct because `kubectl apply -f <directory>` accepts a directory of YAML files and applies all resource definitions within it, making it a convenient way to manage multiple resources declaratively. This is a key feature of `kubectl apply`, which processes each file in the directory and sends the configurations to the Kubernetes API server for creation or update.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • kubectl apply requires the --save-config flag to record the last-applied-configuration annotation

    Why it's wrong here

    The annotation is set automatically by apply.

  • kubectl apply cannot be used on resources that already exist

    Why it's wrong here

    It can be used to update existing resources.

  • kubectl apply can create objects but not update them

    Why it's wrong here

    apply also updates objects.

  • kubectl apply can accept a directory of YAML files with -f

    Why this is correct

    apply accepts files, directories, and URLs.

  • kubectl apply uses a declarative approach and can update existing objects

    Why this is correct

    apply is declarative and updates objects to match the provided config.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse `kubectl apply` with `kubectl create`, mistakenly thinking `apply` cannot update existing resources or that it requires extra flags to record configuration history, when in fact `apply` is inherently declarative and updates are its primary strength.

Detailed technical explanation

How to think about this question

Under the hood, `kubectl apply` sends a PATCH request to the Kubernetes API server using a strategic merge patch (or JSON merge patch for custom resources), which compares the live object state with the `last-applied-configuration` annotation to compute a diff. This allows it to update only the fields that have changed, preserving changes made by other controllers or operators. In real-world GitOps workflows, `kubectl apply` is the standard command for synchronizing a desired state from a Git repository to a cluster.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the KCNA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
