ACI best practice for subnets BD, EPGs

what's best practice for subnets in BD? should we have one subnet per BD?

if I've multiple EGP tied to one BD then is broadcast limited to BD to EPGs?

 

what's best practice for Application profile and EPGs? should I've all EPGs in one application profile?

 

or should I've application profile per application? i.e. say I've two applications - Transaction App & Scan App and each of these applications have Web, App, DB servers. should I've separate EPG for each of these Web, App, DB server and put Web-EPG, APP-EPG, DB-EPG under transaction app for transaction App's servers and Web-EPG, APP-EPG, DB-EPG under transaction app for Scan App's servers ?

I would say... All depend on your needs.
I see 1 EPG = 1 BD setup in case of legacy migration scenario.
You can take a look at best practice doc below
