PDE Operationalizing machine learning models Practice Question
This PDE practice question tests your understanding of operationalizing machine learning models. 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 healthcare organization is deploying a model that processes protected health information (PHI). They need to ensure that the inference data is encrypted in transit and at rest, and access is audited. Which combination of services meets these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Vertex AI Endpoints with VPC-SC, CMEK, and Cloud Audit Logs
Option C is correct because VPC Service Controls (VPC-SC) provides data exfiltration protection and ensures inference data remains within a defined security perimeter, Customer-Managed Encryption Keys (CMEK) encrypt data at rest with keys controlled by the organization, and Cloud Audit Logs capture all access events for auditing. This combination directly addresses encryption in transit (via VPC-SC perimeter enforcement) and at rest (via CMEK), plus access auditing via Cloud Audit Logs.
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.
✗
Cloud Run with VPC connector and Cloud KMS
Why it's wrong here
Cloud KMS is for key management, but VPC-SC is not used, and Cloud Audit Logs are not guaranteed.
✗
Vertex AI Endpoints with IAM and Cloud Monitoring
Why it's wrong here
IAM controls access but not audit logging, and Cloud Monitoring does not provide encryption.
✓
Vertex AI Endpoints with VPC-SC, CMEK, and Cloud Audit Logs
Why this is correct
VPC Service Controls protect against unauthorized data movement, CMEK for customer-managed encryption keys, and Cloud Audit Logs for compliance.

✗
AI Platform Prediction with Cloud Armor
Why it's wrong here
Cloud Armor is for DDoS protection, not encryption or auditing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that IAM and Cloud Monitoring alone satisfy encryption and auditing requirements, but IAM controls access without encrypting data at rest, and Cloud Monitoring tracks performance metrics, not access logs; candidates must recognize that VPC-SC, CMEK, and Cloud Audit Logs are the specific services needed for encryption and auditing in ML inference.
Detailed technical explanation
How to think about this question
VPC Service Controls uses context-aware access policies based on identity, device, and network attributes to create a security perimeter around Vertex AI Endpoints, preventing data exfiltration even if a service account is compromised. CMEK integrates with Cloud KMS to encrypt model data and predictions at rest using AES-256, with the customer holding the key in Cloud HSM for FIPS 140-2 Level 3 compliance. Cloud Audit Logs capture Admin Activity, Data Access, and System Event logs, which are immutable and retained for 400 days by default, enabling forensic analysis of every prediction request.

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 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.
