Your customer requires that a MAF application must have a feature to return the user's current location on a map via the geolocation services. However, you are aware that it is not always possible to guarantee return of the user's current location in a mobile application.

• C.The SOAP web service returns an XML response, whereas the REST service (as per thequestion) returns a JSON response. The two cannot be combined in a unified data control exposure.
• D.Data queried from different web service sources and web service types must be transformed and consolidated on the remote server to ensure unique keys and payloads.
