Salesforce Sharing and Visibility Certification Practice Exam

1. Controlled by Parent

2. Public Read/Write

3. Private

4. Public Read Only

In Salesforce, the sharing settings for any object determine how records of that object can be accessed based on a user's role and profile. When dealing with a custom object that has its External Default Sharing set to Public Read-Only, the valid Internal Default Sharing settings can still provide certain levels of access for internal users. Selecting Public Read Only as the Internal Default Sharing setting allows all internal users to view records of that custom object while restricting them from editing those records. This aligns with the goal of maintaining visibility while controlling edit permissions, which can be critical in scenarios where sensitive data is involved or where records should not be modified by all users. The flexibility in setting Internal Default Sharing enables organizations to manage access on a more granular level depending on the needs of the business. Hence, allowing it to be set as Public Read Only maintains consistency with how external users are granted access. The other options, while they represent potential sharing strategies, do not align with the premise of having Public Read-Only sharing externally. For instance, allowing Public Read/Write would contradict the goal of ensuring external users only have read access. Similarly, Private sharing would restrict access unduly since it would limit visibility strictly to record owners and those above them in the role hierarchy, which may not be
