Final answer:
To share an account record in a private sharing model, Marcus can manually share the record with Sam, add Sam to a shared team for the account, or ask a system administrator for help, ensuring that all sharing complies with the organization's policies and data protection laws.
Step-by-step explanation:
The question is concerning how Marcus, a sales representative in an organization with a private sharing model, can share an account record with his co-worker Sam. In such a sharing model, records are not visible to other users unless they are explicitly shared. Marcus has a few options to share the account record: Manual Sharing - Marcus can manually share the account record with Sam by using the sharing button on the record to grant access.
Using a Shared Team - If they are part of a sales team, Marcus might be able to add Sam to the account team, giving him access to the account. Asking for Administrator Help - If manual sharing is not enabled, Marcus might need to ask the system administrator to share the record with Sam. It is important to follow the organization's sharing policies and ensure that sharing sensitive information complies with any relevant data protection rules.
