Which of the following statements is true for users in a high-volume customer portal?

In a high-volume customer portal, users are typically designed to have limited capabilities, which allows for scalability and efficiency. One of the defining characteristics of a high-volume customer portal is that users do not have ownership of records. This means that while they may interact with records, such as viewing or submitting cases, they cannot own those records in the same way that standard users do in Salesforce.

Ownership of records usually ties into additional permissions and responsibilities assigned to standard user roles. The high-volume model is specifically aimed at providing access to a large user base, primarily focused on self-service and support, rather than giving full user access or ownership capabilities. Therefore, the statement that users cannot own records accurately reflects the constraints of a high-volume customer portal.

By contrast, other statements refer to functionalities that may not apply in this scenario. For instance, while users can create cases or view content, those functionalities are often predicated on different access permissions which are not standard in a high-volume portal.
