Final answer:
A user with CRED permissions and OWD set to public read only can create, read, update, and delete their own contact records, but can only read other users' contact records.
Step-by-step explanation:
With CRED (Create, Read, Edit, Delete) permissions and OWD (Organization-Wide Defaults) set to public read only on a contact object, a user can perform the following actions:
- Create new contact records
- Read existing contact records
- Update and edit their own contact records
- Delete their own contact records
However, they cannot edit or delete contact records owned by other users with higher security settings. They can only view the contact records in read-only mode.
For example, a user with CRED permissions and OWD set to public read only can create a new contact record for a new customer, read contact records of other team members, update their own contact information, and delete their own contact record if required.
