You create Microsoft Windows-based applications. You are creating a sales management application. The application will consume Web services to retrieve and save data to a database server. These Web services will be exposed to a partner extranet so that partners can write applications that will access the same data. The deployment diagram for the entire solution is as shown in the following exhibit. (Refer to the Exhibit.) After deploying the solution, local users and partners report that they are not able to retrieve any data. You find that the client computers are able to access Web applications and Web services hosted by the Web server. You also find that the local applications are able to access other databases on the database server. You need to troubleshoot the issue. What should you conclude?
A.
Firewall settings are blocking access from the Web server to the database server.
B.
Firewall settings are blocking access from the client computers to the Web server.
C.
The Web server is offline.
D.
The database server is offline.
