Answer

The most likely answer  is D. URL filter. This is handy for blocking access to peer-to-peer (P2P) networks such as BitTorrent. You might even use it to block other P2P networks such as Dropbox. An all-in-one security appliance such as the Barracuda Web Security Gateway can be configured for most of the answers listed but the URL filter would be best for blocking specific P2P file sharing websites and networks. “Content inspection” is not enough, we need a device that can do content filtering, which usually includes URL filtering. A bit tricky I know, but remember that inspection is not the act of blocking user access, but it is often required in order to control where the users can ultimately go, and/or to scan for malware.
