Which process is responsible for monitoring overall project progress toward meeting performance objectives?

Correct answer: Monitor and Control Project Work

Option A is correct because Monitor and Control Project Work is the PMBOK process explicitly responsible for tracking, reviewing, and reporting overall project progress against the performance measurement baseline to identify variances and recommend corrective or preventive actions. Option B, Plan Project Management, is a planning process that produces the project management plan and does not perform ongoing monitoring. Option C, Validate Scope, focuses specifically on formal acceptance of completed deliverables by stakeholders, not broad progress monitoring. Option D, Direct and Manage Project Work, is an executing process that carries out the work defined in the project management plan rather than monitoring progress against objectives.
