Universal Container’s Salesforce admin is setting up an opportunity team in Salesforce. What are the required steps while setting up an opportunity team? (Choose three options)

Answer options:

A.Add the team members
B.Assign the role for each member on the opportunity
C.Assign the level of access for each team member
D.Create the role hierarchy for the opportunity team

Correct Answer: A, B, and C 
When you do the setup for the opportunity team in Salesforce, first you need to add the team members, then assign the roles for each of the members on the opportunity, and then you need to assign the access level needed whether it would be read and write access or only read-only access. 
Option D is incorrect because the role hierarchy is related to Salesforce roles, not to the opportunity team.
