Explanation

In a multi-tier web architecture, the component that initiates a request to another service is acting as the client. When the Web application server queries the Database, the Web application server is the client in that transaction.

Common mistakes.

A. The user is the client of the Web application server, not the client in the specific Web application server-to-Database transaction described.
B. The BIG-IP is a traffic management device that sits between clients and servers; it does not initiate the database query described in this scenario.
C. The Database is the server in this transaction - it receives and processes the query initiated by the Web application server, making it the server, not the client.
