Here are the answers,
1)Given both, which one is simpler and better, only focusing on DR feature.
Both are good as long as they align with your requirements. But SRM is being in industry for sometime and could be more comfortable. But both these has pros and cons need to be considered.
2)Does HCX's DR feature require NX-T/NX-V environment as prerequisite ? Again only focusing DR feature of HCX.
HCX need NSX at the Target.
3) Does HCX's L2 extension service require NX-V/NX-T be set up first?
Yes.
