問題文
A company wants group membership driven entirely by attributes so nobody has to maintain lists, but the data in those attributes is unreliable. What does this imply?
選択肢
- Assigned membership has the same dependency, because someone has to read the same unreliable attributes in order to decide who to add, so moving to a rule changes nothing about the underlying data problem.
- Unreliable attributes are acceptable because the membership is re-evaluated frequently, so any wrong value that is later corrected in the source flows through and the group settles on the right membership without manual intervention.
- The rule can compensate for unreliable data by combining several attributes, so that a person is only included when two or three independent fields agree and a single wrong value cannot place them in the wrong group.
- The automation is only as good as the attribute data, so the data quality must be fixed before access decisions are made to depend on it, because a blank or stale attribute silently adds or drops the wrong people.
