C and E are correct related to gathering methods. But D is correct since streamed messages are sent as data on an existing HTTP/2 request and eliminates the overhead of creating a new HTTP/2 request for each unary call.

i go with C&E, D is wrong in my opition because there is always an overhead, even though it is a small one with gRPC

Based on (obviously biased) Cisco documentation, it seems Cisco wants us to select C and D here. Although it is pretty clear D is also correct. It is always CORRECT vs WANTED

C and E because ietf.org states verbatim: "stream data continuously -- with incremental updates", on slide 4, titled: "Streaming telemetry architecture": https://www.ietf.org/proceedings/96/slides/slides-96-rtgwg-7.pdf oh...and gRPC is basically the open source version of what Google MCF is using.

C and E are the correct answers. why not D? Because gRPC has overhead
