Google PCA Design for security and compliance Practice Question
This PCA practice question tests your understanding of design for security and compliance. 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 Google Cloud services can be used to implement a zero-trust architecture for network security? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cloud Armor
Options A, B, and C are correct. Cloud Armor enforces security policies at the edge, Identity-Aware Proxy (IAP) verifies identity and context before granting access, and Access Context Manager defines access levels based on device, IP, etc., to enforce fine-grained access. Option D is wrong because Cloud VPN is for network connectivity, not zero-trust security. Option E is wrong because VPC Networks are the underlying network, but zero-trust requires beyond network perimeters.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
VPC Networks
Why it's wrong here
VPC networks provide network segmentation but not identity- and context-based access.
✗
Cloud VPN
Why it's wrong here
Cloud VPN connects networks, but does not enforce zero-trust per-access.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
