T) Broadcast versus Replicate component. Anyone could u plz explain ?

Broadcast and replicate behavior varies with flow type and default flow type is different for both. It's always difficult to remember it unless you try all scenarios. On a short note when you connect this component between same depth, default flow type for broadcast is all to all and it multiplies the data.  I would suggest to read help and simultaneously run trials. Primary motive of broadcast is data parallelism and it duplicates data in each partition flow. As I said it behaves differently based on flow type and you need to run it to get correct understanding.
