Best Practices/Use Case-based provisioning and Live Media
“Best Practices” and “Use Case-based" provisioning are currently not supported with live media content.
They are only supported with Video On Demand (VoD) content. You need to manually configure the various Behaviors offered to fit your environment for Live content.
Live media delivery with AMD is managed via Media Services Live. Specifics on its set up (and best practice settings) are discussed in the Live Streaming with MSL 4.x and AMD - Getting Started Guide.
