問題文
A utility wants two million residential customers to sign in to a site and see only their own billing records, while 400 internal agents keep working the same records inside the org. What must the architect account for that does not arise with internal users?
選択肢
- Opening the site changes nothing in the sharing design, because the organization wide default already decides what every user of the org is able to see, and the two million residential customers fall under exactly the same default as the 400 internal agents.
- External users inherit visibility through the role hierarchy in the same way internal users do, so the design only has to place each residential customer at the right point of that same hierarchy.
- External access is granted through a different set of mechanisms than the internal role hierarchy, so the design has to state which rows each external user reaches, and the sheer number of those users becomes part of capacity planning.
- Because external users sit above internal users in the hierarchy, opening the site raises the access of every internal user as a side effect, so the only preparation needed is to lower the organization wide default and then rebuild the internal sharing rules from the bottom of the hierarchy upwards.
