- A
To enforce identity-based access control for web applications and SSH/RDP to VMs without requiring a VPN.
IAP provides zero-trust access by verifying the user's identity and context, allowing access to web apps and VMs via SSH/RDP without a VPN.
- B
To manage firewall rules for VPC networks.
Why wrong: VPC firewall rules are managed separately via the VPC firewall service, not IAP.
- C
To provide a VPN connection between on-premises and Google Cloud.
Why wrong: That is the purpose of Cloud VPN or Cloud Interconnect, not IAP.
- D
To act as a web application firewall (WAF) that blocks SQL injection and XSS attacks.
Why wrong: That is the purpose of Cloud Armor. IAP is for identity-based access control.

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. 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.

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
✓
To enforce identity-based access control for web applications and SSH/RDP to VMs without requiring a VPN.
Identity-Aware Proxy (IAP) is a service that provides a zero-trust access control layer for applications and resources. It verifies a user's identity and context before allowing access, enforcing application-level access control. It is not a VPN or firewall; it works at the identity level, not network level. It does not replace Cloud Armor or VPC firewalls but complements them.
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.
