As a part of a project, structured cabling activities have been outsourced to another company.

The project manager should approve the deliverables and monitor the performance of the outsourced structured cabling activities. These are the responsibilities of the project manager when dealing with external vendors or contractors, as they ensure that the quality standards, scope, schedule, and budget are met according to the contract terms and the project plan. The project manager should also communicate regularly with the vendor and provide feedback and guidance as needed. The other options are not correct because:

Purchasing the materials is not the responsibility of the project manager, but the vendor who is performing the structured cabling activities. The project manager should only verify that the materials are suitable and available for the project.

Assigning the resources is not the responsibility of the project manager, but the vendor who is performing the structured cabling activities. The project manager should only ensure that the vendor has the adequate and qualified resources to complete the work.

Accepting delays in the work is not a good practice for the project manager, as it can negatively affect the project schedule, scope, and quality. The project manager should proactively identify and manage the risks and issues that may cause delays, and implement contingency plans or corrective actions if necessary.

Negotiating with the vendors is not a task that the project manager should do during the execution of the structured cabling activities, as it should have been done during the planning and procurement phases of the project. The project manager should only adhere to the contract terms and conditions that have been agreed upon with the vendor, and only renegotiate if there are significant changes or disputes that require it. References = CompTIA Project+ Study Guide: Exam PK0-005, 3rd Edition, Chapter 8: Planning Projects, Part 4 (Procurement and Communication), pages 243-260; CompTIA Project+ Certification Exam Objectives, Domain 2: Project Planning, Objective 2.5: Given a scenario, plan procurement for a project; Domain 3: Project Execution, Objective 3.2: Given a scenario, execute and monitor project tasks using traditional methodologies.
