- A
Use Cloud Security Scanner to scan the production cluster for vulnerabilities.
Why wrong: Cloud Security Scanner scans web applications, not container images.
- B
Enable Cloud Asset Inventory to monitor image vulnerabilities across projects.
Why wrong: Cloud Asset Inventory tracks resources but does not prevent deployment of vulnerable images.
- C
Configure Cloud Build to run a vulnerability scan step before pushing images to Container Registry.
Why wrong: Cloud Build can scan, but it does not enforce that scanned images are used in production; a separate attestation mechanism is needed.
- D
Enable Binary Authorization with a policy that requires attestations from Container Analysis for all deployments in the production cluster.
Binary Authorization ensures only verified images are deployed by requiring attestations from approved authorities like Container Analysis.
Cloud Digital Leader Trust and security with Google Cloud Practice Question
This GCDL practice question tests your understanding of trust and security with google cloud. 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.
A technology company runs its containerized microservices on Google Kubernetes Engine (GKE). The development team frequently pushes new container images to Container Registry, and those images are deployed to a production cluster. The security team recently discovered that a few running containers have critical vulnerabilities from outdated base images. They want to enforce a policy that only vulnerability-scanned and approved images can be deployed in the production cluster. The team uses Cloud Build for CI/CD and Container Analysis for vulnerability scanning. Which solution should they implement to meet this requirement?
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
Enable Binary Authorization with a policy that requires attestations from Container Analysis for all deployments in the production cluster.
Binary Authorization enforces deployment-time policies that require signed attestations from trusted authorities (like Container Analysis) before an image can be deployed on GKE. By configuring a policy that mandates an attestation from Container Analysis (which performs vulnerability scanning), only images that have been scanned and approved can be deployed, directly meeting the requirement to block containers with critical vulnerabilities.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse scanning images (which only identifies vulnerabilities) with enforcing a policy that blocks deployment of vulnerable images, leading them to choose a scanning-only option (like C) instead of the policy enforcement mechanism (Binary Authorization).
Detailed technical explanation
How to think about this question
Binary Authorization uses a policy that references attestors (e.g., a Container Analysis note) to verify that an image has a valid signed attestation before allowing a pod to be created on GKE. The attestation is a cryptographically signed payload (using PKI) that proves the image passed a vulnerability scan; if the attestation is missing or invalid, the admission webhook denies the deployment. In practice, this means even if a developer pushes a vulnerable image directly to the registry, the GKE cluster will refuse to run it unless the image has been scanned and the attestation stored in Container Analysis.
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.
