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.
An organization uses Security Command Center (SCC) premium tier and wants to automatically remediate a specific finding type by disabling public access to Cloud Storage buckets. What is the recommended approach?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set up a Cloud Function triggered by SCC findings to remove public access
Option C is correct because Security Command Center (SCC) premium tier can publish findings to Cloud Pub/Sub, which can trigger a Cloud Function via a push subscription. The Cloud Function can then use the Google Cloud Storage API (specifically, the `storage.buckets.setIamPolicy` method) to remove the `allUsers` or `allAuthenticatedUsers` bindings that grant public access, enabling automated, event-driven remediation without manual intervention.
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.
✗
Use Cloud Pub/Sub alone to listen for SCC findings and then manually remediate
Why it's wrong here
Pub/Sub is part of the pipeline but requires a subscriber to act; Cloud Function is the action.
✗
Use IAM to deny all users except project owners from making buckets public
Why it's wrong here
This is preventive but not automated remediation of existing buckets.
✓
Set up a Cloud Function triggered by SCC findings to remove public access
Why this is correct
SCC can publish findings to Pub/Sub, which triggers a Cloud Function to remediate.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure a Cloud Scheduler job to run a script that checks and removes public access
Why it's wrong here
Cloud Scheduler is not event-driven and would be inefficient for real-time remediation.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between event-driven automation (Cloud Functions + Pub/Sub) and scheduled or manual approaches, so candidates mistakenly choose Cloud Scheduler or IAM deny policies because they think 'automation' means periodic checks or preventive controls, rather than reactive, real-time remediation.
Detailed technical explanation
How to think about this question
Under the hood, SCC findings are published to a Cloud Pub/Sub topic in the format of a SecurityFinding object (as defined by the Security Command Center API). A Cloud Function subscribed to that topic receives the finding payload, parses the finding type (e.g., 'PUBLIC_BUCKET_ACCESS'), and then uses the Google Cloud Storage client library to call `bucket.setIamPolicy()` with a policy that removes any `role: roles/storage.objectViewer` or `role: roles/storage.legacyBucketReader` bindings for `allUsers`. This approach ensures sub-second response times and can be extended to handle multiple finding types via conditional logic.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
