hi Criszhan thank you for the great information,. As you commented Dynamic Quorum okey to configure with 3 nodes, how this will work with 3 nodes ? or its a default configuration as nothing to do for us(feature)
Following note says even you have 3 nodes, better to keep it witness share . I am not sure why and what for? what benefit we will get it from there .

"In Windows Server 2012 R2, the recommendation is to always configure a witness regardless of the number of nodes."
