Explanation

B is correct because the HTTP server is not optional - it is mandatory for centrally deploying and upgrading eSpace IP phones in DHCP Option 246 mode. In this mode, the DHCP server provides the phone with the address of the configuration/upgrade server via Option 246, while the HTTP server is what actually hosts and delivers the configuration files and firmware images to the phones. Without the HTTP server, the phones have nowhere to download their configs or upgrades from, making it just as essential as the DHCP server.

Why A is wrong: Calling the HTTP server "optional" is the flaw in the statement. Both servers work together as a required pair - DHCP Option 246 points the phone to the HTTP server, and the HTTP server fulfills the actual deployment and upgrade. Marking this TRUE would misrepresent a critical infrastructure dependency.

Memory tip: Think of it as a two-key system - DHCP Option 246 is the map (tells the phone where to go), and the HTTP server is the destination (delivers the goods). You can't skip the destination and call it optional; the whole journey is pointless without it. If both are mandatory, the statement is FALSE.
