Universal Containers has a multi -layered distributionstructure. The Main Distributors in each geography work with Regional Distributors to sell and service customers in the region. Universal Containers plans to roll out a Community with the following capabilities: • Main Distributors and Regional Distributors are considered Partner accounts in Salesforce. • Main Distributors can communicate with other Main Distributors. • Regional Distributors can communicate with other Regional Distributors who are managed by the same Main Distributor, but NOT with other Regional Distributors. How should the Salesforce Admin build a Community to meet the requirements?
