- A
Grant the IAP-secured Web App User role to each individual user from the corporate domain.
Why wrong: Works but not scalable; groups are preferred.
- B
Create a Cloud Identity group containing all corporate users, and grant the IAP-secured Web App User role to that group.
Scalable and maintainable approach.
- C
Use a custom SAML attribute in the IdP to filter access.
Why wrong: Extra complexity; group-based access is simpler.
- D
Configure a firewall rule that allows traffic only from the corporate IP range.
Why wrong: IAP works over the internet; firewall rules are not suitable for user-level access.

PCSE Practice Question: Configuring Access Within a Cloud Solution Environment
This PCSE practice question tests your understanding of configuring access within a cloud solution environment. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 wants to allow their employees to access an internal web application running on Compute Engine using Identity-Aware Proxy (IAP). They want to ensure that only users from their corporate domain (example.com) can access the app. What is the recommended approach?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Cloud Identity group containing all corporate users, and grant the IAP-secured Web App User role to that group.
Option B is correct because Identity-Aware Proxy (IAP) uses Cloud Identity groups to manage access at scale. By creating a group containing all corporate users (e.g., from example.com) and granting the IAP-secured Web App User role to that group, you enforce domain-level access without managing individual users. This approach leverages IAP's integration with Cloud Identity to verify the user's email domain against the group membership, ensuring only example.com users can reach the application.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that IP-based firewall rules (Option D) are sufficient for access control, but the trap here is that IAP is specifically designed to replace network-level controls with identity-based access, making IP filtering an outdated and insecure approach in this context.
Detailed technical explanation
How to think about this question
IAP uses signed JWTs (JSON Web Tokens) to verify user identity after authentication via Google's OAuth 2.0 or SAML IdP. When a Cloud Identity group is granted the IAP-secured Web App User role, IAP checks the user's email domain against the group's membership list (which can be synced from Google Workspace or Cloud Identity). This approach ensures that even if a user has a valid Google account but is not in the example.com domain, they are denied access—unlike IP-based rules which can be spoofed or bypassed via VPNs.
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 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.
