Users connect to a host pool from several global locations. Some of the users report slowness and other issues while connecting to the host pool. You want to identify if the issue is related to the latency. What would you check for that?

Answer options:

A.Verify if QOS is enabled for the network of affected users
B.Verify if Round Trip Time(RTT) is less than 150 ms for the affected users
C.Verify if Round Trip Time(RTT) is less than 200 ms for the affected users
D.Verify if Round Trip Time(RTT) is less than 250 ms for the affected users
E.Verifyif there is adequate bandwidth at each remote location of the affected users

Correct Answer: B 
For optimal performance, Round-trip latency from the user`s network to the Azure region where the host pools have been deployed should be below 150 ms.
Option A is incorrect. QoS tags are not honored with internet traffic.
Option B is correct. You need to verify if Round Trip Time is below 150 ms for the affected users.
Option C is incorrect. For optimal performance, Round-trip latency from the user`s network to the Azure region where the host pools have been deployed should be below 150 ms. Therefore, you will verify if Round Trip Time for the affected users is below 150 ms, not 200 ms.
Option D is incorrect. For optimal performance, Round-trip latency from the user`s network to the Azure region where the host pools have been deployed should be below 150 ms. Therefore, you will verify if Round Trip Time for the affected users is below 150 ms, not 250 ms.
Option E is incorrect. Sufficient bandwidth is an important, factor but that is not related to the latency.
