Does anyone know the answer to the following question:
A new help desk employee at a cloud services provider receives a call from a customer. The customer is unable to log into the provider's web application. The help desk employee is unable to find the customer's user account in the directory services console, but sees the customer's information in the application database. The application does not appear to have any fields of password. The customer then remembers the password and is able to log in. The help desk employee still does not see the user account in directory services. Which of the following is the MOST likely explanation?
- A bug has been discovered in the application
- The application uses a weak encryption cipher
- A federated authentication model is being used
- The application uses single sign-on
