A technician is about to install and configure a wireless network at a small branch office. What is the first security measure the technician should apply immediately upon powering up the wireless router?
Configure encryption on the wireless router and the connected wireless devices.
Disable the wireless network SSID broadcast.
Change the default user-name and password of the wireless router.
Enable MAC address filtering on the wireless router.
Which service can be used on a wireless router to prioritize network traffic among different types of applications so that voice and video data are prioritized over email and web data?
NAT
QoS
DNS
DHCP
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?
Require all wireless devices to use the 802.11n standard.
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.
Add a Wi-Fi range extender to the WLAN and set the AP and the range extender to serve different bands.
A technician is troubleshooting a slow WLAN that consists of 802.11b and 802.11g devices . A new 802.11n/ac dual-band router has been deployed on the network to replace the old 802.11g router. What can the technician do to address the slow wireless speed?
Change the SSID.
Configure devices to use a different channel.
Split the wireless traffic between the 802.11n 2.4 GHz band and the 5 GHz band.
Update the firmware on the new router.
A network administrator of a college is configuring the WLAN user authentication process. Wireless users are required to enter username and password credentials that will be verified by a server. Which server would provide such service?
AAA
NAT
SNMP
RADIUS
Which three parameters would need to be changed if best practices are being implemented for a home wireless AP? (Choose three.)
SSID
AP password
antenna frequency
wireless beacon time
wireless network password
A laptop cannot connect to a wireless access point. Which two troubleshooting steps should be taken first? (Choose two.)
Ensure that the wireless NIC is enabled.
Ensure that the laptop antenna is attached.
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.
A network administrator is configuring a RADIUS server connection on a Cisco 3500 series WLC. 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.
It is used to authenticate and encrypt user data on the WLAN.
It is used to encrypt the messages between the WLC and the RADIUS server.
A network engineer is troubleshooting a newly deployed wireless network that is using the latest 802.11 standards. When users access high bandwidth services such as streaming video, the wireless network performance is poor. To improve performance the network engineer decides to configure a 5 Ghz frequency band SSID and train users to use that SSID for streaming media services. Why might this solution improve the wireless network performance for that type of service?
The 5 GHz band has a greater range and is therefore likely to be interference-free.
Requiring the users to switch to the 5 GHz band for streaming media is inconvenient and will result in fewer users accessing these services.
The 5 GHz band has more channels and is less crowded than the 2.4 GHz band, which makes it more suited to streaming multimedia.
The only users that can switch to the 5 GHz band will be those with the latest wireless NICs, which will reduce usage.
Which step is required before creating a new WLAN on a Cisco 3500 series WLC?
Create a new SSID.
Create a new VLAN interface.
Build or have an SNMP server available.
Build or have a RADIUS server available.
A network administrator deploys a wireless router in a small law firm. Employee laptops join the WLAN and receive IP addresses in the 10.0.10.0/24 network. Which service is used on the wireless router to allow the employee laptops to access the internet?
DNS
NAT
DHCP
RADUIS
Which protocol can be used to monitor the network?
AAA
SNMP
DHCP
RADIUS
