Quick Answer
The answer is Managing a Stage Boundary. This process is triggered when a Stage Plan’s tolerances are forecast to be exceeded because it provides the formal mechanism to escalate the deviation to the Project Board. In PRINCE2, tolerances define the acceptable deviation for a stage’s time, cost, scope, risk, or quality; when a forecast shows these will be breached, the Stage Manager cannot simply adjust the plan but must invoke the Managing a Stage Boundary process to produce an Exception Plan and request new authorization. On the PRINCE2 Foundation exam, this question tests your understanding of the escalation hierarchy—specifically that tolerances are managed at the stage level, not the project level, and that the Project Board retains authority for approving any change beyond those tolerances. A common trap is confusing this with the Controlling a Stage process, which handles day-to-day management within tolerances, not the escalation outside them. Remember the memory tip: “Stage Boundary for the big breach, Controlling a Stage for the daily reach.”
This PRINCE2F practice question tests your understanding of prince2 processes. 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 process is triggered when a Stage Plan's tolerances are forecast to be exceeded?
Directing a Project
Why wrong: DP authorizes, but SB produces the plan.
Managing a Stage Boundary
SB includes creating an Exception Plan when tolerances are exceeded.
Controlling a Stage
Why wrong: CS would escalate, but SB is the process for creating an Exception Plan.
Closing a Project
Why wrong: CP is for project closure.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Managing a Stage Boundary
Managing a Stage Boundary is used to produce an Exception Plan and request authorization from the Project Board.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Directing a Project
Why it's wrong here
DP authorizes, but SB produces the plan.
Managing a Stage Boundary
Why this is correct
SB includes creating an Exception Plan when tolerances are exceeded.
Related concept
Authentication checks who the user is.
Controlling a Stage
Why it's wrong here
CS would escalate, but SB is the process for creating an Exception Plan.
Closing a Project
Why it's wrong here
CP is for project closure.
Common exam traps
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
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.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
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
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.
