The project manager should communicate with the affected stakeholders first after realizing that the sign-off for the project scope baseline is delayed due to multiple changes and that the budget for this project is restricted by the project sponsor. The affected stakeholders are those who have an interest or influence on the project and may be impacted by any changes or delays. Communicating with them can help to explain the situation, assess the impact, seek feedback, and manage expectations.

The RACI (Responsible, Accountable, Consulted, Informed) matrix is used to document which resources are responsible for which tasks. The RACI matrix is a tool that helps to clarify roles and responsibilities on a project. It assigns a level of responsibility to each resource involved in the project. References: CompTIA Project+ Study Guide Section 3.4.
The project manager should use a RACI matrix to document which resources are responsible for which tasks.
A RACI matrix is a type of responsibility assignment matrix (RAM) that plots the roles and responsibilities of resources on a project team. RACI stands for Responsible, Accountable, Consulted, and Informed. A RACI matrix can help to clarify who does what on a project, avoid confusion and duplication of work, and improve communication and collaboration among team members.

Explanation
When implementing an IT infrastructure change that takes risks into consideration, the project manager should develop a rollback plan. A rollback plan is a contingency plan that outlines the steps that need to be taken in case the change does not work as expected. It includes a plan to roll back the changes and restore the system to its previous state. References: CompTIA Project+ Study Guide Section 3.3.
The project manager should develop a rollback plan when implementing an IT infrastructure change that takes risks into consideration. A rollback plan is a contingency plan that describes how to revert back to the previous state of the system in case of a failure or disruption during the change implementation. A rollback plan can help to minimize the impact of the change on the system performance and availability and ensure business continuity and data integrity.

Explanation
Lessons learned, removing resources, and removing access are activities that a project manager would perform during the closing phase of a project. Lessons learned is a process of collecting and documenting the knowledge and experience gained from a project for future reference and improvement. Removing resources is a process of releasing or reallocating any human or material resources that were used for the project.
Removing access is a process of revoking any permissions or privileges that were granted to the project team members or stakeholders for accessing any systems or data related to the project. These activities can help to finalize and close a project successfully and ensure that all deliverables are transferred, all documentation is approved and archived, all contracts are closed, and all stakeholders are satisfied.
