Which of the following tasks should the project manager complete first when validating deliverables?

Validating deliverables involves ensuring that the project's outputs meet the defined requirements and objectives. The first step in this process is to review the project objectives to confirm that the deliverables align with the intended goals. This review provides a benchmark against which the deliverables can be assessed, ensuring that they fulfill the project's purpose before seeking stakeholder feedback or assessing documentation.

This aligns with the CompTIA Project+ PK0-005 exam objectives, particularly under Domain 2.1: Explain the value of artifacts in the discovery/concept preparation phase for a project, which emphasizes the importance of aligning deliverables with project objectives.
