A user is configuring a wireless access point and wants to prevent any neighbors from discovering the network. What action does the user need to take?

• 
  

• • Configure DMZ settings.

• • Configure a DNS server.

• • Disable SSID broadcast.

• • Enable WPA encryption.

When a wireless network in a small office is being set up, which type of IP addressing is typically used on the networked devices?

• • network

• • public

• • wireless

• • private

A user has just purchased a generic home router and would like to secure it. What should be done to help secure the wireless home router?

• • Change the default SSID.

• • Set a private IPv4 network for the internal network.

• • Allow only IPv6 traffic to enter the router.

• • Change the default administrator password.

Which protocol could be used by a company to monitor devices such as a wireless LAN controller (WLC)?

• • SSH

• • NTP

• • PAT

• • SNMP

When configuring a Cisco 3500 series wireless LAN controller (WLC) for a WPA2 Enterprise WLAN, what has to be created on the WLC before creating the new WLAN?

• • a security module

• • a new SSID

• a VLAN for the wireless network

• • a security policy

What is a DHCP scope as it relates to a WLAN configured on the WLC controller?

• • a pool of IP addresses for WLAN clients

• • a corporate plan for allocation of IP addresses for wireless clients

• • security rules associated with DHCP for WLANs

• the distance allotted for wireless clients that can receive IP addressing information

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

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.

What functionality is required on routers to provide remote workers with VoIP and videoconferencing capabilities?

• • IPsec

• • PPPoE

• • QoS

• • VPN

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.
