Exam MS-700 topic 1 question 21 discussion

Answer A is correct since we must check if the DSCP value has been set, which is not present in the CQD, see https://techcommunity.microsoft.com/t5/microsoft-teams/call-quality-dashboard-and-qos/m-p/1756178

Network Monitor is outdated: "Network Monitor is the archived protocol analyzer and is no longer under development. Microsoft Message Analyzer is the replacement for Network Monitor. For more details, see Microsoft Message Analyzer Operating Guide." Source: https://docs.microsoft.com/en-us/windows/client-management/troubleshoot-tcpip-netmon

Note You can view DSCP values by using network captures with tools like Network Monitor. After you perform a network capture, you can observe the TOS field in captured data. https://learn.microsoft.com/en-us/windows-server/networking/technologies/qos/qos-policy-scenarios

The Microsoft Teams Call Quality Dashboard provides detailed information about call quality and performance, including data on network conditions, devices, and user experiences during Teams calls. This tool allows you to monitor and analyze call quality and can help you verify if QoS settings are being applied effectively at your branch offices. Using the Microsoft Teams Call Quality Dashboard, you can track metrics related to network performance, jitter, packet loss, and other factors that may impact call quality. This information will help you determine whether QoS policies are effectively prioritizing Teams traffic on your network. Options A, B, and C are not specifically designed for monitoring and confirming the application of QoS settings for Microsoft Teams calls, making option D the most appropriate choice for this scenario.

Answer is D

The answer is D, The giving answer is outdated: The Call Quality Dashboard provides insights into call quality, network performance, and troubleshooting information for Microsoft Teams calls. It allows you to monitor and analyze the quality of calls made using Microsoft Teams, including information related to network conditions, latency, packet loss, and more.

I asked this from chat gpt.. D. Microsoft Teams Call Quality Dashboard. To confirm that Quality of Service (QoS) is being applied at the branch offices, you can use the Microsoft Teams Call Quality Dashboard. This dashboard provides an overview of call quality across the organization and can help you identify if there are any issues with call quality for specific users or locations. In the Call Quality Dashboard, you can view the quality of individual calls, including the MOS (Mean Opinion Score) value, network metrics such as packet loss, and the DSCP value of the call traffic. The DSCP value should correspond to the QoS policy you have configured for Microsoft Teams traffic. The Microsoft Teams Device Usage Report provides information about the devices that are being used to access Microsoft Teams but does not provide information about QoS. The Microsoft Network Monitor and Network Testing Companion are not tools that are commonly used to troubleshoot QoS issues in Microsoft Teams.

To confirm that Quality of Service (QoS) is being applied at the branch offices, you should use network monitoring tools such as Microsoft Message Analyzer or Wireshark. These tools can help you analyze the network traffic and identify if the QoS policies are being applied to the Microsoft Teams traffic. You can look for the Differentiated Services Code Point (DSCP) value of the Microsoft Teams traffic to confirm if it is being marked correctly. The DSCP value should correspond to the QoS policy you have configured for Microsoft Teams traffic. Additionally, you can also check the Quality of Service (QoS) reports in Microsoft Teams admin center to see if there are any issues reported with call quality for the branch offices.

The answer is A The term for QoS is Network Monitor.

Answer : A Question explicitly requires verification: "You need to confirm that QoS is being applied at the branch offices." Below states: https://learn.microsoft.com/en-us/windows-server/networking/technologies/qos/qos-policy-scenarios "Note: You can view DSCP values by using network captures with tools like Network Monitor. After you perform a network capture, you can observe the TOS field in captured data."

D. Microsoft Teams Call Quality Dashboard

when using Microsoft Teams. ===>>> D. Microsoft Teams Call Quality Dashboard

A I asked ChatGPT: "Can I view QoS markings in Microsoft Teams Call Quality Dashboard? No, the Microsoft Teams Call Quality Dashboard does not display Quality of Service (QoS) markings. The dashboard displays a variety of call quality metrics such as packet loss, jitter, and round-trip time, but it does not display information on QoS markings. To view QoS markings, you would need to use a network monitoring tool such as Microsoft Network Monitor or a third-party tool that is able to capture and analyze network traffic. These tools will allow you to view the actual QoS markings in the network traffic and determine if they are being applied correctly."

Make sure your network is ready If you're considering a QoS implementation, you should already have determined your bandwidth requirements and other network requirements. Traffic congestion across a network will greatly impact media quality. A lack of bandwidth leads to performance degradation and a poor user experience. As Teams adoption and usage grows, use reporting, per-user call analytics, and Call Quality Dashboard (CQD) to identify problems and then make adjustments using QoS and selective bandwidth additions.
