7. Why would a technician configure a passphrase for a WLAN on a wireless router?
- to protect someone from changing the configuration
- to protect the SSID from being changed
- to protect someone from cabling directly to the router and accessing the router
- to configure wireless client authentication
8. A customer installs a wireless access point at home in the closet next to the kitchen. The customer mentions that the wireless communication performance seems degraded when the cordless phone or the microwave oven is in use. What is the possible reason for this degradation?
- The surge of electricity when a microwave oven is in use disrupts the operation of the access point.
- The cordless phone joins the WLAN and shares the available bandwidth.
- The wireless signal is in the same radio frequency range as the household devices are in.
- The access point is on the same electrical circuit as the phone base unit and microwave oven are.
- The access point is close to walls.
9. What functionality is required on routers to provide remote workers with VoIP and videoconferencing capabilities?
10. A wireless router is displaying the IP address of 192.168.0.1. What could this mean?
- Dynamic IP address allocation has been configured on the router and is functioning correctly.
- The wireless router has been configured to use the frequencies on channel 1.
- The NAT function is not working on the wireless router.
- The wireless router still has the factory default IP address.
11. A laptop cannot connect to a wireless access point. Which two troubleshooting steps should be taken first? (Choose two.)
- Ensure that the wireless SSID is chosen.
- Ensure that the correct network media is selected.
- Ensure that the NIC is configured for the proper frequency.
- Ensure that the laptop antenna is attached.
- Ensure that the wireless NIC is enabled.
12. In setting up a small office network, the network administrator decides to assign private IP addresses dynamically to workstations and mobile devices. Which feature must be enabled on the company router in order for office devices to access the internet?
- MAC filtering
13. What is a difference between autonomous APs that operate in a home environment and controller-based APs that operate in a corporate environment?
- Controller-based APs can be automatically configured and managed by a WLAN controller.
- Controller-based APs are known as lightweight APs and require an initial configuration to operate.
- Autonomous APs do not support PoE.
- Autonomous APs incorporate the functions of a router, switch, and AP into one device.
14. Which WLC tab would a network administrator typically use to see a summary view of the most heavily used WLANs including the number of clients using a particular WLAN?
15. Users on an IEEE 802.11n network are complaining of slow speeds. The network administrator checks the AP and verifies it is operating properly. What can be done to improve the wireless performance in the network?
- Switch to an 802.11g AP.
- Split the wireless traffic between the 802.11n 2.4 GHz band and the 5 GHz band.
- Set the AP to mixed mode.
- Change the authentication method on the AP.
16. What is the first security setting that should be applied when connecting a wireless router in a small network?
- Change the default administrative username and password.
- Enable encryption on the wireless router.
- Disable the wireless network SSID broadcast beacon.
- Enable MAC address filtering on the wireless router.
17. Which option is an easy way to improve wireless performance on an 802.11n wireless router?
- Connect a Wi-Fi range extender on the 2.4 GHz band to a wireless router on the 5 GHz band.
- Require all wireless devices to use the 802.11g standard.
- Use different SSID names for the 2.4 GHz and 5 GHz bands.
- Use the same SSID name for all wireless bands.
18. Which Cisco 3504 WLC dashboard menu option provides an overview of the number of configured wireless networks, associated access points (APs), and active clients?
- Access Points
- Network Summary
19. Which protocol is used to monitor a network?
20. Which service on a wireless router enables a host with an internal private IPv4 address to access an outside network using a public IPv4 address?
21. Which service available on some wireless routers can be used to prioritize email over web data traffic?
22. What must be done before creating a new WLAN on a Cisco 3500 series WLC?
- Build or have a RADIUS server available.
- Build or have an SNMP server available.
- Create a new SSID.
- Create a new VLAN interface.
23. Which frequency band SSID name should users with time-sensitive applications connect to?
- The 2.4 GHz band, because it is less crowded than the 5 GHz band.
- The 2.4 GHz band, because it has more channels than the 5 GHz band.
- The 2.4 GHz band, because the channel is likely interference-free.
- The 5 GHz band, because it has more channels than the 2.4 GHz band.
24. A Cisco 3500 series WLC is configured to access a RADIUS server. The configuration requires a shared secret password. What is the purpose for the shared secret password?
- It allows users to authenticate and access the WLAN.
- It is used by the RADIUS server to authenticate WLAN users.
