A network administrator has received calls every day for the past few weeks from three users who cannot
access the network. The administrator asks all the users to reboot their PCs, but the same users still cannot
access the system. The following day, three different users report the same issue, and the administrator asks
them all to reboot their PCs; however, this does not fix the issue. Which of the following is MOST likely
occurring?


A. Incorrect firewall settings
B. Inappropriate VLAN assignment
C. Hardware failure
D. Overloaded CAM table in switch
E. DHCP scope exhaustion
