Exam MS-720 topic 2 question 10 discussion

This question repeats several times with a different set of answers.. in all of them the answer has to do with network roaming policy. Why not in this one?

Option B will allow only 1 successful meeting if all features are used. Option C will allow only 3 concurrent calls to be successful. Disabling video would be the right option for this low a bandwidth 1.5 mbps which is for whole site. tagging all traffic with dscp 46 will do no differentiating to audio traffic, and dscp can't do anything about low bandwidth if these are the only options, just run the network connectivity tool i would say

B is correct - only voice traffic needs to be maintained. Tagging all traffic isn't targeting just voice traffic.

Give answer is correct.: DSCP (Differentiated Services Code Point) is a field in the IP header used for traffic differentiation and prioritization in networks. Assigning a DSCP value of 46 to all traffic is a way to provide a common level of service for specific types of traffic. This can help ensure that important traffic such as real-time voice or video gets priority over other traffic, improving their quality and reliability. It is important to note that the specific use of DSCP 46 and its impact on network behavior depends on the configuration of network devices and the agreed upon network policy.

From my point of view , the answer B is the correct one. Using a DSCP value doesn't warrant bandwith management.
