ACE Practice Question: Your team uses Cloud Build to build and push…
This ACE practice question tests your understanding of your team uses cloud build to build and push…. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Enable BinAuthz on the GKE cluster; Cloud Build automatically signs images when BinAuthz is enabled.
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.
B
Distractor review
Use Artifact Registry vulnerability scanning; images that pass scanning are automatically trusted by GKE.
Vulnerability scanning identifies known CVEs but does not create attestations or integrate with BinAuthz trust enforcement.
C
Distractor review
Add a Cloud Build step that runs `gcloud container binauthz attestations sign-and-create` without additional configuration.
The signing command requires a pre-existing attestor, note, and KMS key. Running it without setup will fail.
D
Best answer
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 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.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

FAQ
Questions learners often ask
What does this ACE question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: 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. — Binary Authorization (BinAuthz) works by: 1) Creating an attestor with an associated note in Container Analysis. 2) Generating a signing key pair (often via Cloud KMS). 3) Configuring Cloud Build to sign images after build using the private key (creating an attestation). 4) Creating a BinAuthz policy on the GKE cluster that requires the attestation. 5) GKE enforces the policy at pod admission time — unsigned images are rejected by the BinAuthz admission controller.
What should I do if I get this ACE question wrong?
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related ACE questions on access control and AAA configuration.
