In Adobe Workfront, the methodology that matches a traditional, sequential project approach is Waterfall. Adobe Workfront learning content describes traditional or waterfall methodology as a linear process where teams plan the final product and then move through the steps or phases required to deliver it. This is different from Scrum, where teams work from a backlog, plan iterations or sprints, and deliver work in smaller increments. It is also different from Kanban, which uses a board-based flow of work items through statuses rather than strict sequential project phases. Adobe Workfront documentation also distinguishes team types as Scrum Team, Kanban Team, and Waterfall Team, showing that Waterfall is recognized as a Workfront team/work management approach. Because the question describes each phase being completed before the next begins, that aligns directly with the Waterfall model's structured, sequential planning style. Therefore, the correct answer is C. Waterfall.

In scenarios where multiple individuals are assigned to a task, Workfront allows each user to mark the task as "Done with my part" to signify their portion of the task is complete. This ensures that progress is tracked for each user, and the task is only marked as complete when all assigned users have finished their work.

In Adobe Workfront, the Workload Balancer is the correct tool for reviewing resource utilization across multiple projects and making staffing decisions. Adobe documentation explains that the Workload Balancer helps users visualize and manage people's workloads and demand in one view, at the global, project, or team level. This makes it useful for resource managers who need to see whether team members are overallocated, underutilized, or available for more work across different projects. Adobe's best-practice guidance also states that the Workload Balancer provides a clear visual mapping of overallocation and underutilization, helping managers determine which team members have bandwidth to complete tasks or issues on time. Scenario Planner is used for high-level planning scenarios and job-skill forecasting, not day-to-day staffing review. Timesheets are used to track and submit time worked, but they do not provide the same forward-looking workload and capacity view. Therefore, the correct answer is C. Workload Balancer.

In Workfront, cross-project predecessors allow dependencies between tasks across different projects. To ensure that Task 1 in Project 1 starts only after the final milestone of Project 2, the project manager must configure a cross-project predecessor linking the final milestone in Project 2 to Task 1 in Project 1. This establishes a dependency and aligns the timelines of the two projects.

In Adobe Workfront, the initial project setting used to identify and report on key tasks is the Milestone Path. Adobe documentation explains that milestones can be associated with tasks to indicate important steps in the life of a project, and that the collection of predefined milestones is called a milestone path. Workfront also states that milestone paths allow key tasks in a project to be associated with predefined milestones, giving managers and stakeholders a high-level view of project progress. In practice, the project owner applies a milestone path to the project first, then associates individual key tasks with milestones from that path. This supports milestone reporting and milestone views across projects. Schedule controls working and non-working time for date calculations, while Resource Leveling Mode relates to resolving resource allocation conflicts. Neither setting is designed to mark key tasks for milestone reporting. Therefore, the correct answer is A. Milestone Path.
