Two weeks after installation, a network technician is now unable to log onto any of the newly installed company
switches. The technician suspects that a malicious user may have changed the switches’ settings before they
were installed in secure areas. Which of the following is the MOST likely way in which the malicious user gained
access to the switches?

A.
Via SSH using the RADIUS shared secret

B.
Via HTTP using the default username and password

C.
Via console using the administrator’s password

D.
Via SNMP using the default RO community

Explanation:
A new network switch is accessed via HTTP to perform the initial configuration. The username and password
used is a factory default.
