In a multisite environment, what is the default sharing behavior of user profiles?
A.
They are shared across all the sites.
B.
They are not shared and hence are separate across the sites.
C.
They can be configuredinto groups that specify the sharing behavior.
D.
There is no default behavior. It needs to be custom designed and implemented.
Explanation:
User profiles (and therefore logins) are always shared across all sites in the
application.
Note: In the simplest case, these sites may share only user profiles, so a customer registered on
one site is also registered on the other. In more complex implementations, the sites may share
shopping carts, so a customer can include items from both sites in a single order. The bargainbrand site might also include upsell recommendations for (and links to) items on the luxury brand
site, or the sites might share gift lists.
