Deploying and implementing a cloud solution →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is to create a Cloud KMS key and attestor, configure Cloud Build to create attestations post-build, then set a BinAuthz policy requiring the attestation on the GKE cluster. This sequence is correct because Binary Authorization relies on a separate attestation step—Cloud Build does not automatically sign images when BinAuthz is enabled; you must explicitly generate a signed attestation using the attestor and KMS key after each successful build, then enforce that attestation via a policy on the cluster. On the Google Associate Cloud Engineer exam, this question tests your understanding of the binary authorization cloud build attestation workflow, often appearing as a multi-step ordering task where the common trap is assuming Cloud Build signs images by default. Remember the mnemonic “Key, Attest, Enforce” to recall the correct order: first create the cryptographic key and attestor, then generate the attestation in Cloud Build, and finally apply the policy on GKE.

Google ACE Deploying and implementing a cloud solution Practice Question

This ACE practice question tests your understanding of deploying and implementing a cloud solution. 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.

Your team uses Cloud Build to build and push Docker images to Artifact Registry. A new security requirement mandates that only images signed by Cloud Build (using Binary Authorization with attestors) can be deployed to your GKE cluster. Which sequence of steps correctly implements this?

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

✓

Create a Cloud KMS key and attestor, configure Cloud Build to create attestations post-build, then set a BinAuthz policy requiring the attestation on the GKE cluster.

Option B is correct because it follows the required workflow: you must first create a Cloud KMS key and an attestor in Binary Authorization, then configure Cloud Build to generate an attestation (signed by the attestor) after each successful build. Finally, you set a Binary Authorization policy on the GKE cluster that enforces the attestation, ensuring only signed images are deployed. Cloud Build does not automatically sign images when BinAuthz is enabled; the attestation must be explicitly created.

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.

  • ✗

    Enable BinAuthz on the GKE cluster; Cloud Build automatically signs images when BinAuthz is enabled.

    Why it's wrong here

    Enabling BinAuthz on GKE does not automatically configure Cloud Build to sign images. Signing requires explicit attestor and KMS key configuration in the build pipeline.

  • ✓

    Create a Cloud KMS key and attestor, configure Cloud Build to create attestations post-build, then set a BinAuthz policy requiring the attestation on the GKE cluster.

    Why this is correct

    This is the correct sequence: KMS key for signing → Container Analysis note → attestor referencing the key → Cloud Build signing step → BinAuthz policy requiring the attestor's signature at deploy time.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Use Artifact Registry vulnerability scanning; images that pass scanning are automatically trusted by GKE.

    Why it's wrong here

    Vulnerability scanning identifies known CVEs but does not create attestations or integrate with BinAuthz trust enforcement.

  • ✗

    Add a Cloud Build step that runs `gcloud container binauthz attestations sign-and-create` without additional configuration.

    Why it's wrong here

    The signing command requires a pre-existing attestor, note, and KMS key. Running it without setup will fail.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Google Cloud often tests the misconception that enabling Binary Authorization on a cluster automatically integrates with Cloud Build to sign images, when in fact you must manually create the attestor, key, and attestation step.

Trap categories for this question

  • Command / output trap

    The signing command requires a pre-existing attestor, note, and KMS key. Running it without setup will fail.

Detailed technical explanation

How to think about this question

Binary Authorization uses attestors that are backed by asymmetric keys stored in Cloud KMS; the attestation is a signed payload containing the image digest. The Cloud Build step must use the `--artifact-url` and `--attestor` flags with the correct project and location, and the attestor must be bound to the KMS key via the `gcloud container binauthz attestors create` command. A common subtlety is that the attestation is stored in a separate Artifact Analysis note, and the BinAuthz policy must reference the attestor by its resource name, not just the project ID.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
