Network Testing Companion Tests for Teams Readiness

MS-700 By islever Editorial Last updated

Plan network settings for Teams

Short answer

AC The Network Testing Companion includes trace route information and open/blocked ports checks to assess network readiness.

Question

You plan to deploy Microsoft Teams to a remote location.
You perform a network readiness assessment for Microsoft Teams by using the Network Testing Companion.
Which two tests are included in the assessment? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
  1. trace route information Correct Answer
  2. video quality tests
  3. open and blocked ports Correct Answer
  4. audio quality tests
  5. Quality of Service (QoS) validation

Key Takeaways

This question tests knowledge of the specific components of the deprecated Network Testing Companion tool versus the newer Network Assessment Tool, with a common trap being the inclusion of media quality tests.

The Network Testing Companion for Microsoft Teams assesses network readiness by performing trace route information and checking for open and blocked ports. It does not include audio or video quality tests, which are handled by other tools.

Common mistake: Many candidates incorrectly select audio and video quality tests because they assume the tool measures call performance, but these tests are part of the separate Network Assessment Tool or client-side diagnostics, not the legacy companion.

Expert Analysis

Why the Answer Is Correct

The correct answers are A (trace route information) and C (open and blocked ports). The Microsoft Teams Network Testing Companion was a lightweight utility designed to verify basic network connectivity prerequisites. It specifically performed two functions: it traced the route to Microsoft 365 endpoints to identify routing issues and checked if required TCP/UDP ports were open or blocked along that path. This ensured the network infrastructure could support the traffic without firewall interference.

Why the Other Options Are Wrong

Options B (video quality tests) and D (audio quality tests) are incorrect because the Network Testing Companion did not measure media performance metrics like jitter, latency, or packet loss during actual calls. These quality assessments are part of the newer Network Assessment Tool or the Client Health dashboard. Option E (QoS validation) is also incorrect as the companion tool did not validate Quality of Service tagging or prioritization settings on the network.

Community Comment Notes

Community feedback is mixed due to the tool's deprecation. Some users argue for video/audio tests based on outdated or confused resources, while others correctly identify the port and trace route functionality. One commenter noted, "The companion performs a trace route... It checks the required endpoint/port set," aligning with official documentation. Another user pointed out that the tool is often confused with the Network Assessment Tool, leading to errors in selecting quality tests.

Exam Strategy

When studying for MS-700, distinguish clearly between the legacy 'Network Testing Companion' (ports/route) and the modern 'Network Assessment Tool' (quality metrics). If a question specifies 'Companion', think connectivity checks; if it specifies 'Assessment', think media quality.

Frequently Asked Questions

Why are audio/video tests not in the Network Testing Companion?

The companion only checks connectivity prerequisites (ports/routes). Media quality requires active call simulation, which is done by the Network Assessment Tool.

Is the Network Testing Companion still used?

It has been largely replaced by the Microsoft Teams Network Assessment Tool for more comprehensive testing including QoS and media quality.

    A. trace route information B. video quality tests The Network Testing Companion for Microsoft Teams includes two tests that are used to assess network readiness for deploying Teams: A. trace route information: This test provides information on the route that network traffic takes between the user's device and the Teams service. This information can be used to identify network bottlenecks and other issues that could affect performance. B. video quality tests: This test measures the quality of the video feed that is received by the user's device. This includes factors such as frame rate, resolution, and packet loss. It's important to note that options C, D and E are not included in the assessment, Open and blocked ports are related to network security, audio quality tests are related to the audio quality in calls, and Quality of Service (QoS) validation is related to network traffic prioritization. ...

    No, you need to install the Network Assessment Tool to use the Network Testing Companion. By the way, this dependency is something another question asks about.

    The Network Testing Companion includes the following two tests as part of the network readiness assessment for Microsoft Teams: Video quality tests (B): These tests evaluate the performance and quality of video calls within Microsoft Teams. They assess factors such as latency, jitter, and packet loss to ensure optimal video communication. Audio quality tests (D): Similar to video quality tests, audio quality tests focus on evaluating the performance and clarity of audio calls in Teams. They help identify any issues related to call quality, such as echo, distortion, or dropped audio.

    The two tests included in the network readiness assessment for Microsoft Teams using the Network Testing Companion are: C. Open and blocked ports: This test checks whether the necessary ports required for Microsoft Teams are open and accessible or if they are blocked, which could hinder the proper functioning of the application. E. Quality of Service (QoS) validation: This test assesses the Quality of Service settings on the network to ensure that Microsoft Teams can deliver a reliable and high-quality audio and vídeo experience.

    Right, Connectivity firstly and then the Audio Quality Test

    why video quality tests is not needed?

    The companion performs a trace route to Microsoft 365 endpoints, showing the hop-by-hop path and helping identify routing/peering issues. It checks the required endpoint/port set for Teams and reports which ports are open or blocked on the path.

    Tyffty - I guess yes nothing in new teams tenant is called network testing companion, I have only head of the network assessment tool
