Matt, an administrator, notices a flood fragmented packet and retransmits from an email server.
After disabling the TCP offload setting on the NIC, Matt sees normal traffic with packets flowing in
sequence again. Which of the following utilities was he MOST likely using to view this issue?

A.
Spam filter

B.
Protocol analyzer

C.
Web application firewall

D.
Load balancer

Explanation:
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.
