Exam MS-700 topic 2 question 51 discussion

Answer is definitely D, also documented here: https://docs.microsoft.com/en-us/microsoftteams/qos-in-teams#validate-your-qos-implementation CQD is mentioned there only for helping too decide if the port rannge needs to be adjusted.

Repeat of question 34: https://www.examtopics.com/exams/microsoft/ms-700/view/23/

I think the keywords in the question are "specific times of the day" AI answer is. To verify whether Quality of Service (QoS) is being applied to the calls, you should use B. Microsoft Call Quality Dashboard. This tool provides rich set of reports, including call quality at different times of the day, and can help you troubleshoot call quality issues in Microsoft Teams. It also allows you to check if QoS policies are being applied correctly. The other options are not specifically designed for this purpose. The Microsoft Teams client (A) is the application used for making the calls, Network Testing Companion © is used for testing network performance, and Network Monitor (D) is a protocol analyzer. None of these provide the specific QoS information that the Call Quality Dashboard does.

To verify whether Quality of Service (QoS) is being applied to the voice calls made from Microsoft Teams, you should use option C, Network Testing Companion. This tool allows you to assess the network conditions and test the connection quality specifically for Microsoft Teams. By using Network Testing Companion, you can analyze the network performance, including metrics like latency, jitter, and packet loss, which can affect call quality. It will help you determine if QoS is being applied correctly and identify any network issues that may be causing poor call quality at specific times of the day.

B. Microsoft's Call Quality Dashboard. The Microsoft Call Quality Dashboard (CQD) is a tool that provides detailed information about the quality of voice and video calls in Microsoft Teams. It allows administrators to analyze bandwidth, packet loss, delay, and other metrics to identify call quality issues and take steps to resolve them.

The correct answer is B. Microsoft Call Quality Dashboard. To verify whether Quality of Service (QoS) is being applied to the calls, you can use the Microsoft Call Quality Dashboard. This dashboard provides insights into the call quality of Microsoft Teams and Skype for Business calls, including information on call reliability, network performance, and call quality issues.

You can not see DCSP mark on CDQ. This can only be done with a network monitoring tool at both ends of the call. You may have configured QoS within Teams but if there is a packet shaper at either end, the DCSP marker may be removed and CDQ will not show this.

The answer is D. Guaranteed.

It's B. D is outdated

Answer is B . https://docs.microsoft.com/en-us/microsoftteams/monitor-call-quality-qos Call Quality Dashboard (CQD) gives you a network-wide view of call quality across your organization. Use CQD information to help you identify and fix problems. First, Set up CQD. Then read Manage call and meeting quality in Teams.

https://docs.microsoft.com/en-us/learn/modules/plan-configure-network-settings-for-microsoft-teams/05-implement-quality-service Validate the QoS implementation For the QoS to be effective, the DSCP value set by the Group Policy object needs to be present at both ends of a call. By analyzing the traffic generated by the Teams client, you can verify if the DSCP value has not changed or been stripped out when the Teams workload traffic traverses moves through the network. It is also recommended that you use the Call Analytics and Call Quality Dashboard for evaluating your changes. Network Monitor is the archived protocol analyzer and is no longer under development https://docs.microsoft.com/en-us/windows/client-management/troubleshoot-tcpip-netmon

Question should say "a network monitor" in my opinion. Network Monitor sounds like an embedded tool such as CQD etc

Correct answer is D - Network monitor Justification - I have used this tool extensively to verify DSCP values against the posrt range for audio, video and application sharing set in QoS. The network monitor tool needs to be run at client and server level (in case of on-prem but not possible in Teams :P ) Hope this is a clear answer

Only a network monitor that can inspect the packet will show if the QoS marking is applied

Answer is correct Validate the QoS implementation For the QoS to be effective, the DSCP value set by the Group Policy object needs to be present at both ends of a call. By analyzing the traffic generated by the Teams client, you can verify if the DSCP value has not changed or been stripped out when the Teams workload traffic traverses moves through the network.
