Microsoft Power BI Data Analyst 認定 PL-300 試験問題 (Q230-Q235):

質問 # 230
You have a collection of reports for the HR department of your company. The datasets use row- level security (RLS). The company has multiple sales regions that each has an HR manager. You need to ensure that the HR managers can interact with the data from their region only. The HR managers must be prevented from changing the layout of the reports.
How should you provision access to the reports for the HR managers?

正解：D

解説：
Note: Row-level security (RLS) with Power BI can be used to restrict data access for given users.
Filters restrict data access at the row level, and you can define filters within roles. In the Power BI service, members of a workspace have access to datasets in the workspace. RLS doesn't restrict this data access.
