- A
Configure OAuth 2.0 consent screen and create credentials.
Why wrong: This is needed but typically done after enabling IAP? Actually, you need OAuth consent screen before enabling IAP? In the console, you set up OAuth consent screen as part of IAP configuration. But the first step is to enable IAP on the resource.
- B
Enable IAP on the backend service of the load balancer.
Enabling IAP on the backend service is the initial step to protect the application.
- C
Create a firewall rule to allow traffic only from IAP IP ranges.
Why wrong: Firewall rules are necessary to allow IAP traffic, but the first step is to enable IAP itself.
- D
Grant the IAP-secured Web App User role to the corporate domain users.
Why wrong: This is done after IAP is enabled.

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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 security engineer needs to configure Identity-Aware Proxy (IAP) for a web application running on Compute Engine. The goal is to ensure that only authenticated users from the corporate domain can access the application. What is the first step in the configuration?

Correct answer & explanation
✓
Enable IAP on the backend service of the load balancer.
The first step is to enable IAP on the backend service or resource. Then configure OAuth consent screen, create an IAP access policy, and assign IAP-secured Web App User role to users. The correct order is to enable IAP first.
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
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.
