Will the Halo 5 Beta run on Halo 5 servers/engine?

Basically, I know 343i doesn’t want the launch issues of Halo MCC and they do not want to carry this trend over to Halo 5. I believe that since the Halo 5 beta will be pure matchmaking for tuning and understanding gameplay then that must mean 343i will need to use the same servers Halo 5 will be using in order to ensure the MM experience is the same or as similar as possible to the beta launching this December. The Networking for Halo 5, I am assuming, will be utilized for this Beta.

343i needs this Beta to launch without issues, it will give me a sigh of relief thinking that Halo MCC launching the way it did was due to the prioritization being the Halo 5 beta all along…
