PCSE Supporting compliance requirements Practice Question
This PCSE practice question tests your understanding of supporting compliance requirements. 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 company must enforce that no data can be accessed from outside a specific set of Google Cloud projects. They want to ensure that only authorized services can communicate between projects. Which TWO controls should they implement? (Choose TWO.)
Access Context Manager defines and manages context-aware access policies that can be used with VPC Service Controls to enforce access based on context.
B
VPC Service Controls
VPC Service Controls establish a data security perimeter that restricts data access from outside the perimeter.
C
Cloud Armor
Why wrong: Cloud Armor protects against DDoS attacks, not data access enforcement.
D
Identity-Aware Proxy (IAP)
Why wrong: IAP controls user access to applications based on identity, not service-to-service communication between projects.
E
Cloud NAT
Why wrong: Cloud NAT allows outbound internet access but does not enforce data access restrictions.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Access Context Manager
VPC Service Controls create a perimeter around resources, and Access Context Manager defines context-aware access policies based on attributes like IP range, device policy, etc.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Access Context Manager
Why this is correct
Access Context Manager defines and manages context-aware access policies that can be used with VPC Service Controls to enforce access based on context.
Related concept
Static NAT maps one inside address to one outside address.
✓
VPC Service Controls
Why this is correct
VPC Service Controls establish a data security perimeter that restricts data access from outside the perimeter.
Related concept
Static NAT maps one inside address to one outside address.
✗
Cloud Armor
Why it's wrong here
Cloud Armor protects against DDoS attacks, not data access enforcement.
✗
Identity-Aware Proxy (IAP)
Why it's wrong here
IAP controls user access to applications based on identity, not service-to-service communication between projects.
✗
Cloud NAT
Why it's wrong here
Cloud NAT allows outbound internet access but does not enforce data access restrictions.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCSE NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Access Context Manager — VPC Service Controls create a perimeter around resources, and Access Context Manager defines context-aware access policies based on attributes like IP range, device policy, etc.
What should I do if I get this PCSE question wrong?

Static NAT maps one inside address to one outside address.
