Which of the following factors affects the network bandwidth required for a positive Azure Virtual Desktop user experience?

The requirement for network bandwidth in an Azure Virtual Desktop environment is significantly influenced by display resolution. Higher display resolutions, such as 4K or even 1080p, necessitate more data to be transmitted over the network since the amount of pixel information that needs to be rendered increases. This means that for higher resolutions, a larger bandwidth is essential to ensure that the user experiences smooth and visually appealing graphics without latency or lag. If the bandwidth is insufficient for the chosen display resolution, users might encounter degraded visual quality or delayed updates to changes on the screen, which can negatively impact the overall experience.

While other factors like latency, network loss, and output frame rate also play roles in overall user experience, they don't directly dictate the amount of bandwidth required in the same way that display resolution does. Latency affects responsiveness, network loss may lead to packets being dropped, and output frame rate pertains to the frames being delivered per second, but the underlying requirement for data transmission relies heavily on the resolution at which the desktop is being rendered.
