Which network topology is shown in the following diagram? correct answer: mesh
, Which network topology is being implemented when each node connects to exactly two other
nodes, forming a single continuous pathway for signals through each node? correct answer: ring
In which physical LAN topology are nodes connected to each other with a backbone cable that
loops around and ends at the same point it started? correct answer: ring

A user that does not want to be identified while communicating on a network uses an application
to alter the computer's identity. Which type of exploit is being perpetrated? correct answer:
spoofing
An attacker attempts to misdirect traffic on a network back to the attacker by corrupting the
network computer's cache of IP address to MAC address mappings that are cached.
Which exploit is the attacker perpetrating? correct answer: ARP poisoning
Which exploit actually breaches the physical medium or uses devices to monitor signals from
outside the physical medium itself? correct answer: wiretapping
Which type of attack can overwhelm a web server by inserting more data into a web form than
the system was configured to hold? correct answer: buffer overflow
Which type of attack sends an email claiming to be from a reputable business in order to entice
the recipient to provide sensitive information? correct answer: phishing
A user on a network is planning to launch an exploit against a coworker in a neighboring
