Ann, the network administrator, is receiving reports regarding a particular wireless network in the building. The network was implemented for specific machines issued to the developer department, but the developers are stating that they are having connection issues as well as slow bandwidth. Reviewing the wireless router’s logs, she sees that devices not belonging to the developers are connecting to the access point. Which of the following would BEST alleviate the developer’s reports?
A. Configure the router so that wireless access is based upon the connecting device’s hardware address.
B. Modify the connection’s encryption method so that it is using WEP instead of WPA2.
C. Implement connections via secure tunnel with additional software on the developer’s computers.
D. Configure the router so that its name is not visible to devices scanning for wireless networks.

B. Man-in-the-middle
C. ARP poisoning
D. Rogue access point
Ann, a sales manager, successfully connected her company-issued smartphone to the wireless network in her office without supplying a username/password combination.

Which of the following is preventing the device from connecting?
A. WPA2-PSK requires a supplicant on the mobile device.
B. Hardware address filtering is blocking the device.
C. TCP/IP Port filtering has been implemented on the SOHO router.
D. IP address filtering has disabled the device from connecting.

A new virtual server was created for the marketing department. The server was installed on an existing host machine. Users in the marketing department report that they are unable to connect to the server. Technicians verify that the server has an IP address in the same VLAN as the marketing department users. Which of the following is the MOST likely reason the users are unable to connect to the server?
A. The new virtual server’s MAC address was not added to the ACL on the switch
B. The new virtual server’s MAC address triggered a port security violation on the switch
C. The new virtual server’s MAC address triggered an implicit deny in the switch
D. The new virtual server’s MAC address was not added to the firewall rules on the switch
