Cisco 2, Module 13

A laptop cannot connect to a wireless access point. Which two troubleshooting steps should be taken first? (Choose two.)

• 1. Ensure that the wireless SSID is chosen.

• 1. Ensure that the NIC is configured for the proper frequency.

• 1. Ensure that the wireless NIC is enabled.

• 1. Ensure that the laptop antenna is attached.

• 1. Ensure that the correct network media is selected.

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

• wireless

• public

• network

• private

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?

• Disable SSID broadcast.

• Configure a DNS server.

• Enable WPA encryption.

• Configure DMZ settings.

What is a difference between autonomous APs that operate in a home environment and controller-based APs that operate in a corporate environment?

• Autonomous APs do not support PoE.

• Autonomous APs incorporate the functions of a router, switch, and AP into one device.

• 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.

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 new SSID

• a VLAN for the wireless network

• a security policy

• a security module

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?

• QoS

• NAT

• MAC filtering

• UPnP

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?

• Set a private IPv4 network for the internal network.

• Change the default SSID.

• Allow only IPv6 traffic to enter the router.

• Change the default administrator password.

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 wireless router still has the factory default IP address.

• The NAT function is not working on the wireless router.

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.

• Change the authentication method on the AP.

• Set the AP to mixed mode.

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

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

• security rules associated with DHCP for WLANs

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

• a pool of IP addresses for WLAN clients
