An organization recently upgraded its wireless infrastructure to support 802.1x and requires all clients to use
this method. After the upgrade, several critical wireless clients fail to connect because they are only pre-shared
key compliant. For the foreseeable future, none of the affected clients have an upgrade path to put them into

integrating the non-compliant clients into the network?

The helpdesk is receiving multiple calls about slow and intermittent Internet access from the finance
department. The following information is compiled:
Caller 1, IP 172.16.35.217, NETMASK 255.255.254.0
Caller 2, IP 172.16.35.53, NETMASK 255.255.254.0
Caller 3, IP 172.16.35.173, NETMASK 255.255.254.0
All callers are connected to the same switch and are routed by a router with five built-in interfaces. The
upstream router interface’s MAC is 00-01-42-32-ab-1a
