What can be practical use-case for that?

which one?  

Customer with three different branches wants to has everything on one sandbox. However they would like to set that specific journeys would be visible for specific users. Is that possible?

Query Service - is user able to Create Table ( without Data Distiller SKU ) ?

Is it possible to set up in journey or in batch campaign that the sendout would be realised only between for example 10am-20pm?

Could you explain that in detail? You can render for multiple placements on a front-end different eligible offers for different html elements using one Rule. Inside that Rule would be loop which goes through every element of the response?

I have got similar use-case.Out of curiosity (I do not understand) you generating an offers in AJO or other system?The sendout is done through AJO?How you handle this? Mike

Is this somewhere explained in detail?If I have multiple placements at different urls with different offers available for each placement what is the most effective way to render this? Using one rule or multiple rules? What is the best practice to do this at scale?

Is it correct that one tag property can track multiple domains? 

I am making an assessment for the bank. They import external audiences on a daily basis. I am thinking if this can affect negatively in the long-term the effectiveness of the platform?
