Obtaining approval for changes to software is crucial to ensure that the changes do not negatively impact other functionalities of the software. Approval processes typically involve a review that assesses the potential impacts of the change, which helps in mitigating risks associated with the change.

References = The answer is based on standard project management practices and the typical use of change control processes in software development. For detailed information, please refer to the CompTIA Project+ Study Guide and other official CompTIA resources.

Multitier architecture is a type of software architecture that is suitable to support enterprise-level client-server solutions. Multitier architecture divides an application into logical layers or tiers that are distributed among different servers or machines. Each tier performs a specific function or role and communicates with other tiers through well-defined interfaces. Multitier architecture can provide benefits such as scalability, performance, security, maintainability, and reusability for complex and large-scale applications.

A velocity chart is a tool used in agile project management to track the progress and performance of a project team over time. It shows the number of features or user stories completed in each iteration or sprint. The planned timeline line represents the expected or ideal velocity, while the actual effort line shows the actual or achieved velocity. By comparing the two lines, the Scrum master can identify any gaps, trends, or issues in the project delivery.

Based on the image, the most likely update that the Scrum master can provide to the senior management team is D. The project is trending ahead of schedule. This is because the actual effort line is above the planned timeline line for most of the time, indicating that the project team is completing more features than expected in each sprint. This means that the project is ahead of schedule and has a positive velocity variance. 

Evaluating the impact to baselines (such as schedule and budget) helps determine the delay’s effect on the project. This aligns with CompTIA Project+ guidance on project control, which emphasizes analyzing impacts before taking corrective actions.
