The answer is Controlling a Stage. This is the correct process because, in PRINCE2, an Exception Plan is a replacement for the current Stage Plan, created when the project manager forecasts a deviation beyond the agreed tolerances. Once the Project Board authorizes the Exception Plan, the project does not start a new process; instead, it returns to the Controlling a Stage process to manage the work defined in that new plan, ensuring day-to-day management continues under the same process. On the PRINCE2 Foundation exam, this question tests your understanding of process triggers and the flow between stages—a common trap is confusing this with Managing a Stage Boundary, which creates the Exception Plan but does not execute it. Remember the memory tip: “Approval hands off to Control”—the Board approves, then the manager controls the execution.
PRINCE2F Practice Question: Overview of PRINCE2 and the project environment
This PRINCE2F practice question tests your understanding of overview of prince2 and the project 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.
Which PRINCE2 process is triggered by the authorization of an Exception Plan?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Controlling a Stage
An Exception Plan is approved by the Project Board, and the project then returns to the Controlling a Stage process to execute the plan.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Managing Product Delivery
Why it's wrong here
Managing Product Delivery is focused on work package acceptance and execution.
✗
Directing a Project
Why it's wrong here
Directing a Project authorizes stages and exception plans but is not triggered by them.
✓
Controlling a Stage
Why this is correct
Correct. After an Exception Plan is approved, the Project Manager executes it within Controlling a Stage.
Related concept
Authentication checks who the user is.
✗
Managing a Stage Boundary
Why it's wrong here
Managing a Stage Boundary produces the Exception Plan but is not triggered by its authorization.
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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
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 PRINCE2F questions on access control and AAA configuration.
