Network Testing Companion Prerequisites for Teams

Troubleshoot audio, video, and client issues

You have a Microsoft 365 subscription. You plan to implement Microsoft Teams. You need to perform network quality and connectivity tests from an on-premises network to Microsoft 365 Online services by using the Network Testing Companion. You install the Network Testing Companion module on a local Windows 10 device. Which additional software should you install to perform the tests?

Network Assessment Tool
Windows Performance Analyzer (WPA)
the Microsoft Teams desktop client Correct Answer
Windows Assessment Toolkit

Answer Correct answer: C — Install the Microsoft Teams desktop client to provide the necessary authentication and traffic simulation context for the Network Testing Companion.

Community Insight

The question asks for additional software required to run the Network Testing Companion; the trap is assuming a standalone network diagnostic tool suffices, whereas Teams requires its own client for context.

To perform network quality tests using the Microsoft Teams Network Testing Companion, you must install the Microsoft Teams desktop client alongside the companion module. This ensures the tool can authenticate and simulate real user traffic.

Many users select Option A (Network Assessment Tool) because it is an older legacy tool often associated with Skype for Business. However, the modern Network Testing Companion specifically requires the Teams client to function.

Required prerequisite — the companion uses it (signed-in user) to execute the tests.

Windows Performance Analyzer is a powerful tool for analyzing system and network performance on Windows machines. It can be used to inspect network traffic and identify if QoS markings are present on the packets related to Microsoft Teams calls. By capturing and analyzing network traces, WPA can help confirm whether QoS policies are effectively applied to prioritize Microsoft Teams traffic.

Expert Analysis

Why the Answer Is Correct

The Microsoft Teams Network Testing Companion is designed to evaluate network performance specifically for Teams calls. It relies on the Microsoft Teams desktop client (Option C) to provide the necessary authentication context and to generate realistic traffic patterns that mimic actual user behavior. Without the client installed, the companion cannot properly execute the connectivity and quality tests against Microsoft 365 services.

Why the Other Options Are Wrong

Option A, the Network Assessment Tool, is a legacy tool primarily for Skype for Business and is not the prerequisite for the modern Teams Network Testing Companion. Option B, Windows Performance Analyzer, is used for deep-dive packet capture analysis but is not a runtime dependency for the companion tool itself. Option D, Windows Assessment Toolkit, is a general suite for OS deployment and evaluation, unrelated to Teams network testing prerequisites.

Community Comment Notes

Community consensus strongly supports Option C. One commenter noted, "Required prerequisite — the companion uses it (signed-in user) to execute the tests," highlighting the authentication dependency. Another user confirmed this by stating, "is it still relevant in 2021?" implying awareness of its current status. While some confused it with the legacy Network Assessment Tool, the majority correctly identified the Teams client as the essential component.

Exam Strategy

When dealing with Microsoft Teams troubleshooting tools, always check if the tool requires the application itself to be installed for context or authentication. Don't confuse legacy Skype for Business tools with modern Teams equivalents.
