A rollback plan, also known as a backout plan, is a strategy designed to reverse changes made during a project
in case of failure or undesired results1. A rollback plan is a form of risk response that allows the project to
restore the previous state and minimize the impact of the issue. A rollback plan is usually created during the
planning phase and implemented during the execution or closing phase of the project. The other options are
not correct because:
A compliance check is a process that ensures that the project meets the relevant standards, regulations,
and requirements. A compliance check is not a risk response, but rather a quality control or assurance
activity.
A release plan is a document that outlines the scope, schedule, and resources for delivering a product or
service to the customer. A release plan is not a risk response, but rather a communication or scope
management tool.
A validation check is a process that verifies that the project deliverables meet the customer's needs and
expectations. A validation check is not a risk response, but rather a quality control or assurance
activity. References = CompTIA Project+ Study Guide: Exam PK0-005, 3rd Edition, Chapter 10:

The next step in the process after defining tasks, durations, resources, and costs is to seek baseline approval. A
baseline is an approved version of a project plan that serves as a reference point for measuring progress and
performance throughout the project lifecycle. A baseline typically includes scope, schedule, cost, quality, and
risk parameters. Seeking baseline approval involves presenting the project plan to key stakeholders and
obtaining their formal agreement on the project objectives and deliverables. Baseline approval can help to
establish clear expectations, avoid scope creep, and facilitate change control during project execution.
The NEXT step after defining tasks, durations, resources, and costs during the planning phase is to seek
baseline approval. Baseline approval involves finalizing the project plan and gaining approval from
stakeholders, establishing the plan as the baseline for the project's performance. References: CompTIA

Presentation, application, and data processing. Presentation, application, and data processing are the three
logical and physical computing tiers that make up a three-tier architecture. A three-tier architecture is a type of
software architecture that separates an application into three layers or tiers that run on different servers or
machines. Each tier performs a specific function or role and communicates with other tiers through
well-defined interfaces. The presentation tier is the user interface and communication layer of the application,
where the end user interacts with the application. The application tier is the logic or middle tier of the
application, where data is processed using business rules. The data processing tier is the data or back-end tier
of the application, where data is stored and managed12

Explanation
To validate that a project has been successfully completed. The intent and purpose of a project closeout report is to validate that a project has been successfully completed and to summarize the goals, objectives, and outcomes of the project, as well as the lessons learned and the feedback from stakeholders. A project closeout report is a document that is submitted at the end of a project to officially conclude it and release the resources and contracts involved. It is useful for evaluating the project's success and improving the performance of future projects12
