You design the security roles for the Power Platform solution. 
What are two privileges that you can use in the design?

Answer options:

A.Unit-based
B.Row-level
C.Task-based
D.Entity-level
E.Record-level

Correct Answers: C and E 
As Solution Architect, you need to understand the basis of the security role and its importance in the Dataverse security model. Dataverse provides a flexible and robust security system. Environment security is based on business units, security roles, and field security profiles. The Business unit security model is the basis for Dataverse security. The model controls access to the data using security roles, teams, and users. By linking all of them together, you are getting a role-based security model. 
The security role defines how a user accesses different types of records. Each role has two privileges: Record-level — these privileges are tasks that users can apply to the table and table records. They include eight tasks: Create, Read, Write, Delete, Append, Append To, Assign, and Share.
Task-based — these privileges grant users access to specific tasks, like assigning a manager to the user or approving knowledge articles.
The role privileges are cumulative. If a user has several security roles, the user can use all the privileges that every role has. 
Each of the tasks has an access level. The access level defines the depth of the access in the business unit or organization for the role or user. There are five access levels: Global or Organization, Deep or Parent: Child Business Units, Local or Business Units, Basic or User, and None. 
This type of granularity works for record-level access. For the task-based privileges, the access has only two settings: None and Organization. 
The Dataverse provides two types of ownership for the standard custom tables: User or Team and Organization. 
Organization-owned tables do not have Assign or Share privileges because both tasks require an owner to assign to or share. There are no record owners for organization-owned tables. 
All other options are incorrect.
