Show Suggested Answer Hide Answer
Suggested Answer: B 🗳️
A protocol analyzer is a tool used to examine the contents of network traffic. Commonly known as a sniffer, a protocol analyzer can be a dedicated hardware device or software installed onto a typical host system. In either case, a protocol analyzer is first a packet capturing tool that can collect network traffic and store it in memory or onto a storage device. Once a packet is captured, it can be analyzed either with complex automated tools and scripts or manually.
Incorrect Answers:
A: A spam filter is a software or hardware tool whose primary purpose is to identify and block/filter/remove unwanted messages (that is, spam). Spam is most commonly associated with email, but spam also exists in instant messaging (IM), short message service (SMS), Usenet, and web discussions/forums/comments/ blogs. Because spam consumes about 89 percent of all email traffic (see the Intelligence Reports at www.messagelabs.com), its essential to filter and block spam at every opportunity.
C: A web application firewall is a device, server add-on, virtual service, or system filter that defines a strict set of communication rules for a website and all visitors.
Its intended to be an application-specific firewall to prevent cross-site scripting, SQL injection, and other web application attacks.
D: A load balancer is used to spread or distribute network traffic load across several network links or network devices.
