You are a global admin in a company with a Microsoft 365 subscription. You have set up a retention policy retaining the information in all sharepoint sites for 5 years. Another administrator in your company has created a data retention label with a retention period of 2 years. A Sharepoint site owner named Brian tags his site with the label with 2 years retention for items. 
How long will the information in Brian’s sharepoint site be retained?

Answer options:

A.Due to conflicting retention settings the information is not retained.
B.2 years
C.5 years
D.7 years

Correct Answer: C 
The longest retention period wins. In this scenario the policy scoped at all sharepoint sites with a retention period of 5 years will be the effective policy.
