Exam MS-721 topic 1 question 24 discussion

To ensure that all users at the site with a 1.5-Mb connection have a good voice experience in Microsoft Teams, the best option would be: A. Tag all traffic with a DSCP value of 46. Tagging traffic with a DSCP (Differentiated Services Code Point) value of 46 prioritizes voice traffic, ensuring that it receives the necessary bandwidth and low latency required for a good voice experience. This is crucial especially in a scenario where the available bandwidth is limited. The other options either restrict the use of video or do not adequately address the prioritization of voice traffic.

It cannot be A as the traffic is over internet we can apply QOS but it will not be end to end - It should not be B as the video for region 1 users only impacts them any guests with video will be able to use video C

C is the answer

Option A: Tagging all traffic with a DSCP (Differentiated Services Code Point) value of 46 is a common practice for prioritizing voice over IP (VoIP) traffic in a network. This could help ensure a good voice experience by giving voice traffic higher priority over other types of traffic. Option B: Assigning the Region1 users a meeting policy that has IP video disabled could potentially improve voice experience by reducing the overall bandwidth usage. However, this would also mean that users won’t be able to use video in their meetings. Option C: Creating and assigning a Teams Network Roaming Policy that has IP video disabled is similar to Option B. It could improve voice quality by reducing bandwidth usage, but at the cost of disabling video. Option D: Assigning the Region1 users a meeting policy that has a media bit rate of 1,500 Kbs could potentially improve voice quality by limiting the amount of bandwidth that can be used for media in Teams meetings. However, this would also limit the quality of video and other media.

The scenario is for a specific site that is bandwidth challenged and mentions a "good voice experience" but doesn't specifically mention meetings. Options B & D specifically apply to meetings. Network Roaming Policies (option C) seem like the right option

I think is A, the statement is about how to implement QoS A- A QoS implementation will acomplish the mission prioritizing the voice stream over the others, so that, we just need to prioritize voice traffic through a DSCP tag. C- It dissables a feature that might be necessary. D - It will apply to all the streams (audio,video, content sharing) and it isn't focusing on voice experience. https://learn.microsoft.com/en-us/microsoftteams/qos-in-teams#best-practice

This option directly addresses the network bandwidth available at the site and adjusts the media bit rate accordingly for a better voice experience.

I think B as for C - Creating and assigning a Teams Network Roaming Policy: Roaming policies are primarily designed to manage network connectivity when users move between locations, not for optimizing bandwidth usage within a specific site.

This setting determines the media bit rate for audio, video, and video-based app sharing in meetings for people in your organization. This setting gives you granular control over managing bandwidth in your organization. Depending on the meetings scenario, we recommend to have enough bandwidth in place for a good quality experience. The minimum value is 50 Kbps and the maximum value depends on the meeting scenario. For meetings that need the highest quality video experience, such as CEO board meetings and Teams live events, we recommend you set the bandwidth to 10 Mbps.

Not quite sure if it is C or D. C would make more sense as disabling video would ensure voice quality is better https://learn.microsoft.com/en-us/microsoftteams/network-roaming-policy
