In Agile project management, the iteration review is a meeting held at the end of an iteration where the team demonstrates the work completed during the iteration.

It allows stakeholders to see the tangible results of the development efforts and provides a platform for immediate feedback.

The answer is based on general Agile practices and the role of iteration reviews in Agile project management, which are commonly included in PMP study materials and the PMBOK guide.
