Which of the following would a security administrator implement in order to identify a problem between two
applications that are not communicating properly?

A.
Protocol analyzer

B.

D.

Explanation:
A Protocol Analyzer is a hardware device or more commonly a software program used to capture network data
communications sent between devices on a network. Capturing and analyzing the packets sent between
applications on systems that are not communicating properly, could help determine the cause of the issue.
Well known software protocol analyzers include Message Analyzer (formerly Network Monitor) from Microsoft
and Wireshark (formerly Ethereal).
