Exam 3V0-752 topic 1 question 37 discussion

It might sound crazy, but the answer might be D. https://docs.vmware.com/en/VMware-Horizon/2103/horizon-remote-desktop-features/GUID-220442CF-EA01-470E-A381-1BED9BC0B81C. html Both UDP and H264 ARE ENABLED by default. Both UDP and H264 can be configured by GPO. However, there is an important note at this link about H264: https://techzone.vmware.com/resource/vmware-blast-extreme-optimization-guide#sec2-sub2 => "However, compared to other codecs, H.264 REQUIRES MORE PROCESSING POWER to perform its encoding and decoding operations. Fortunately, this processing can be offloaded from the CPU to graphics cards (GPU) in the device." The question does not say that the devices have a graphics card that supports the offloading, but rather a GPO setting that improves performance. If H264 is disabled, JPG/PNG encoding will be used, which requires less processing power, improving performance.

The correct answer is "Enable UDP Protocol" - this wasn't the default behaviour in previous versions of Horizon which this exam is based on.

UDP is the Blast Default protocol so there is no need to enable it. Disabling UDP will cause more harm than good. The answer is A. H.246 is a video compression that can be offloaded to the client.

I think this answer is C. Based on the TechZone page: Because of its efficiency and excellent performance, UDP, which is the default transport protocol Blast Extreme uses, should not be changed, with two exceptions. For the following conditions, VMware recommends that you use TCP rather than UDP: When traffic must pass through a UDP-hostile network service or device such as a TCP-based SSL VPN, which re-packages UDP in TCP packets If WAN circuits are experiencing very high latency (250 milliseconds and greater) For all other network conditions, VMware recommends that you use UDP for the best user experience. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead.

a tricky question, udp can improve the performance in lan for blast, isn't it?
