- A
Use Cloud IAM Conditions to grant roles with a time constraint (e.g., request.time < timestamp).
IAM Conditions can include temporal conditions, providing just-in-time access that expires automatically.
- B
Create custom roles that are only granted during incident response drills.
Why wrong: This does not provide just-in-time access; roles persist until revoked.
- C
Use Cloud Audit Logs to monitor and revoke access after the incident.
Why wrong: This is a detective and reactive measure, not just-in-time provisioning.
- D
Use VPC Service Controls to allow access only from specific IPs.
Why wrong: VPC Service Controls restrict data access based on context, but are not designed for time-based privileged access.

PCDE Practice Question: Bootstrapping a Google Cloud Organisation for DevOps
This PCDE practice question tests your understanding of bootstrapping a google cloud organisation for devops. 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.
An organization wants to implement privileged access management (PAM) for their Google Cloud environment. They need to grant temporary, just-in-time access to production projects for incident responders. Which GCP service should they use?
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
✓
Use Cloud IAM Conditions to grant roles with a time constraint (e.g., request.time < timestamp).
Cloud IAM Conditions with Access Context Manager can be used to enforce time-based conditions on IAM roles. Additionally, using Cloud IAM's 'iam.roles.update' with time-based conditions or using the Cloud Asset Inventory for access approval are not standard. The best approach is to use Cloud IAM Conditions to grant roles that expire after a defined duration, combined with Access Approval for review.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Why this is correct
IAM Conditions can include temporal conditions, providing just-in-time access that expires automatically.
Related concept
Authentication checks who the user is.

Create custom roles that are only granted during incident response drills.
Why it's wrong here
This does not provide just-in-time access; roles persist until revoked.
- ✗
Use Cloud Audit Logs to monitor and revoke access after the incident.
Why it's wrong here
This is a detective and reactive measure, not just-in-time provisioning.
- ✗

Why it's wrong here
VPC Service Controls restrict data access based on context, but are not designed for time-based privileged access.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related PCDE questions on access control and AAA configuration.
