Smoke testing is the best fit because it is a quick, high-level validation that a new build’s most critical functions work and the build is stable enough to proceed to deeper testing. The scenario specifically says “ready for the next testing phase,” which is exactly the gate smoke testing supports: confirm the build is not “broken” and that core paths execute without major failures. CompTIA Project+ includes smoke testing as one of the testing cycles/methods candidates should recognize in project quality activities. ()

The other options are not the best match. Unit testing is low-level testing of individual components (often done by developers) and doesn’t validate that the integrated build’s critical workflows function end-to-end. Regression testing is broader and verifies existing features weren’t broken by changes; it typically takes more time and is usually run after the build passes smoke checks. Performance testing evaluates responsiveness, throughput, and resource usage—important, but not the initial readiness check for a new build entering the next test stage.

So, to quickly confirm essential functionality and determine readiness to proceed, the PM should ensure a smoke test is performed.

The current stage of the project team is norming, which is the third stage of the five stages of team development. In this stage, the team members have resolved their conflicts and differences, and have established a sense of cohesion and collaboration. They are more productive, supportive, and cooperative, and they follow the agreed norms and rules of the team. They also communicate effectively and seek feedback and assistance from each other. The norming stage is preceded by the forming stage, where the team members get to know each other and the project goals, and the storming stage, where the team members experience disagreements and challenges. The norming stage is followed by the performing stage, where the team members work efficiently and autonomously towards the project outcomes, and the adjourning stage, where the team members complete the project and celebrate their achievements.

The primary reason to update the budget during execution is to track and manage the project’s financial condition. As the project progresses, actual costs, commitments, and forecasts change due to procurement, labor consumption, change requests, risks/issues that materialize, and replanning. Updating the budget enables the PM and stakeholders to see whether the project is trending within the approved funding, to manage burn rate, and to take corrective actions early (cost control, scope trade-offs, re-baselining through change control).

Evaluating the communication plan (A) is not a budget purpose. Reporting risks and issues (C) is important, but that’s the role of risk/issue management artifacts and status reporting—budget updates support the financial dimension of project health. Distributing resources (D) is a resourcing activity; budget informs resourcing decisions, but the key objective of an updated budget is accurate financial control and forecasting.

In Project+ terms, this is part of performance monitoring and project controls: keeping cost information current so decision-makers can manage funding, approvals, and corrective actions with reliable data rather than outdated estimates.
