Exam MS-700 topic 4 question 42 discussion

Option B https://learn.microsoft.com/en-us/microsoftteams/qos-in-teams "Using port-based tagging, your network's router examines an incoming packet, and if the packet arrived using a certain port or range of ports, it identifies it as a certain media type and puts it in the queue for that type, adding a predetermined DSCP mark to the IP Packet header so other devices can recognize its traffic type and give it priority in their queue."

On exam 31/03/2023 B. In Group Policy Management, create a Group Policy setting to specify DSCP values. By setting the Insert Quality of Service (QoS) markers for real-time media traffic as Enabled in the Microsoft Teams admin center, you allow Teams to automatically assign audio and video data packets with a Differentiated Services Code Point (DSCP) value. To ensure that computers prioritize real-time media traffic, you will need to create a Group Policy setting to specify the DSCP values. This will ensure that real-time media traffic has priority over other network activities. Setting the media port range and media bit rate is not necessary to prioritize audio and video during Teams meetings. Creating a network roaming policy in the Teams PowerShell module is not relevant to this scenario.

ChatGPT agrees with answer B

The answer has to be "B". "A" states: "configure the media port range to use any available ports." You don't want to configure it for any available ports...

In my opinion it should be A, as after activating QoS, we must select the port ranges for each real traffic in Meeting Settings (it automatically creates the related GPO). Actually to check it’s working, firstly check that the GPO’s are crated, and then run the Network Monitor to ensure the ports are properly used. Don’t need toncreate the GPO’s manually!

Researched Best practice to set up QoS and it doesnt not mention adjusting use any port. Going with B because it is needed. https://learn.microsoft.com/en-us/microsoftteams/qos-in-teams-clients

Pffttt never forget your QoS, it's the bane of my existence

Its B.
