The answer is enabling data encryption at rest using Cloud KMS, implementing VPC Service Controls, and applying IAM with least privilege. These three steps form the foundation for securing a generative AI pipeline on Vertex AI with sensitive data because encryption protects stored data from unauthorized access, VPC Service Controls prevent data exfiltration by restricting network boundaries, and least-privilege IAM ensures only necessary permissions are granted to users and services. On the Google Cloud Generative AI Leader exam, this question tests your ability to distinguish secure configurations from common pitfalls—like using a public endpoint with an API key, which exposes the pipeline, or disabling audit logging, which removes visibility into threats. A frequent trap is assuming encryption alone is sufficient, but defense-in-depth requires all three controls working together. Memory tip: think “EVI” for Encryption, VPC, and IAM—the three pillars that lock down sensitive data from storage to access to network egress.
Generative AI Leader Google Cloud's Generative AI Offerings Practice Question
This Generative AI Leader practice question tests your understanding of google cloud's generative ai offerings. 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.
Which THREE steps are required to secure a generative AI pipeline that uses Vertex AI and involves sensitive customer data?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use VPC Service Controls to create a perimeter around Vertex AI resources
Options A, B, and E are correct. Data encryption at rest protects stored data; VPC Service Controls prevent data exfiltration; IAM with least privilege controls access. Option C (public endpoint with API key) is insecure. Option D (disable audit logging) reduces security visibility.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 VPC Service Controls to create a perimeter around Vertex AI resources
Why this is correct
VPC-SC prevents data from leaking outside the perimeter.
Related concept
Authentication checks who the user is.
✓
Apply IAM roles with least privilege and use service accounts for the pipeline
Why this is correct
Least privilege minimizes risk of unauthorized access.
Related concept
Authentication checks who the user is.
✗
Expose the prediction endpoint publicly with an API key
Why it's wrong here
Public endpoints increase attack surface; use private endpoints with IAM.
✓
Enable data encryption at rest using Cloud KMS
Why this is correct
Encryption protects data at rest from unauthorized access.
Related concept
Authentication checks who the user is.
✗
Disable audit logging to reduce data exposure
Why it's wrong here
Audit logging is crucial for security monitoring and compliance.
Common exam traps
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.
Detailed technical explanation
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.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related Generative AI Leader questions on access control and AAA configuration.
