Which two settings can be used to update the contact link for an organization in ArcGIS Online?

The correct answer pertains to the requirement for a contact link to function properly. A contact link in ArcGIS Online must use valid mailto link syntax, which facilitates email communication by allowing users to click the link and open their email client with the pre-populated email address. This syntax typically begins with "mailto:" followed by the email address, making it essential for ensuring the link sends users directly to the right point of contact efficiently.

While other options, such as providing an administrator's name and email address or contact information for the administration department, can add context and usefulness to how users engage with the organization, they do not specifically dictate the format needed for a functional contact link. Similarly, a valid website URL doesn't directly pertain to updating a specific contact link but rather points to a broader web presence. Hence, the requirement for valid mailto syntax stands out as the necessary component for updating the contact link effectively within the system.
