(Part 3) Modules 10 – 13: L2 Security and WLANs

A network administrator is configuring port security on a Cisco switch. The company security policy specifies that when a violation occurs, packets with unknown source addresses should be dropped and no notification should be sent. Which violation mode should be configured on the interfaces?

• off

• restrict

• protect

• shutdown

A network administrator is working to improve WLAN performance on a dual-band wireless router. What is a simple way to achieve a split-the-traffic result?

• • Add a Wi-Fi range extender to the WLAN and set the AP and the range extender to serve different bands.

• • Check and keep the firmware of the wireless router updated.

• • Make sure that different SSIDs are used for the 2.4 GHz and 5 GHz bands.

• • Require all wireless devices to use the 802.11n standard.

Which access control component, implementation, or protocol controls what users can do on the network?

• accounting

• 802.1X

• authorization

• authentication

Which type of wireless network is suitable for providing wireless access to a city or district?

• • wireless wide-area network

• • wireless personal-area network

• • wireless local-area network

• • wireless metropolitan-area network
