Guys.. I would need help to understand this question

it's from Oliver Lehmann

You are assigned as a project manager for an internal project. During cost planning and budgeting you discovered that there are peak times of costs during the project and other times when costs are fairly low. What could this mean for the project?

1 The fiscal budget mechanism which is used by the performing organization may not allow for cost peaks in your project, and you may have to level out expenditures over time.
