The Cisco Catalyst 2950 Series Switch is a fixed-configuration, stackable standalone switch that provides wire-speed Fast Ethernet and Gigabit Ethernet connectivity. You work as a network administrator for the P4Spany. Study the exhibit carefully. Some 2950 series switches are connected to the conference area of the corporate headquarters network. The switches offer two to three jacks per conference room to host laptop connections for employees who visit the headquarters office. When many employees come from other locations, you often discover that hubs have been connected to wall jacks in the conference area although the ports on the access layer switches were not intended to support multiple workstations. What would you do to prevent access by multiple laptops through a single switch port and still leave the switch functional for its intended use?
A. Implement Port Security on all interfaces and use the port-security mac-address sticky command to limit access to a single MAC address.
B. Implement Port Security at global configuration mode and use the port-security maximum 1 command to allow each switch only one attached hub.
C. Configure static entries in the switch MAC address table to include the range of addresses used by visiting employees.
D. Implement Port Security on all interfaces and use the port-security maximum 1 command to limit port access to a single MAC address.
