SWRE Unit 12

A network administrator is adding a new WLAN on a Cisco 3500 series WLC. Which tab should the administrator use to create a new VLAN interface to be used for the new WLAN? (Such a dumb question)

• • WIRELESS

• • MANAGEMENT

• • CONTROLLER

• • WLANs

Answer explanation

Just memorise the right tab

After attaching four PCs to the switch ports, configuring the SSID and setting authentication properties for a small office network, a technician successfully tests the connectivity of all PCs that are connected to the switch and WLAN. A firewall is then configured on the device prior to connecting it to the Internet. What type of network device includes all of the described features?

• • firewall appliance

• • wireless router

• • switch

• • standalone wireless access point

A network administrator is configuring a WLAN. Why would the administrator change the default DHCP IPv4 addresses on an AP?

• • to restrict access to the WLAN by authorized, authenticated users only

• • to monitor the operation of the wireless network

• • to reduce outsiders intercepting data or accessing the wireless network by using a well-known address range

• • to reduce the risk of interference by external devices such as microwave ovens

A technician is troubleshooting a slow WLAN and decides to use the split-the-traffic approach. Which two parameters would have to be configured to do this? (Choose two.)

• Configure the 5 GHz band for streaming multimedia and time sensitive traffic.

• • Configure the security mode to WPA Personal TKIP/AES for one network and WPA2 Personal AES for the other network

• Configure the 2.4 GHz band for basic internet traffic that is not time sensitive.

• • Configure the security mode to WPA Personal TKIP/AES for both networks.

• • Configure a common SSID for both split networks.

A network administrator is configuring a WLAN. Why would the administrator disable the broadcast feature for the SSID?

• • to eliminate outsiders scanning for available SSIDs in the area

• • to reduce the risk of interference by external devices such as microwave ovens

• • to reduce the risk of unauthorized APs being added to the network

• • to provide privacy and integrity to wireless traffic by using encryption

A technician is configuring a router for a small company with multiple WLANs and doesn’t need the complexity of a dynamic routing protocol. What should be done or checked?

• • Verify that there is not a default route in any of the edge router routing tables.

• • Create static routes to all internal networks and a default route to the internet.

• • Create extra static routes to the same location with an AD of 1.

• • Check the statistics on the default route for oversaturation.

A network administrator of a small advertising company is configuring WLAN security by using the WPA2 PSK method. Which credential do office users need in order to connect their laptops to the WLAN?

• • the company username and password through Active Directory service

• • a key that matches the key on the AP

• • a user passphrase

• • a username and password configured on the AP

Answer explanation

When a WLAN is configured with WPA2 PSK, wireless users must know the pre-shared key to associate and authenticate with the AP.

On a Cisco 3504 WLC Summary page ( Advanced > Summary ), which tab allows a network administrator to configure a particular WLAN with a WPA2 policy? (Terrible question)

• • WLANs

• • SECURITY

• • WIRELESS

• • MANAGEMENT

Answer explanation

Just got to memorise it. The WLANs tab in the Cisco 3504 WLC advanced Summary page allows a user to access the configuration of WLANs including security, QoS, and policy-mapping.

A network administrator is configuring a WLAN. Why would the administrator use a WLAN controller?

• • to centralize management of multiple WLANs

• • to provide privacy and integrity to wireless traffic by using encryption

• • to facilitate group configuration and management of multiple WLANs through a WLC

• • to provide prioritized service for time-sensitive applications

A network administrator is configuring a WLAN. Why would the administrator use RADIUS servers on the network?

• • to centralize management of multiple WLANs

• • to restrict access to the WLAN by authorized, authenticated users only

• • to facilitate group configuration and management of multiple WLANs through a WLC

• • to monitor the operation of the wireless network
