Each WLAN needs its own virtual interface.

22
Q

To troubleshoot WLAN issues, what should be done when the network is slow?

Study These Flashcards
A
  • Upgrade your wireless clients
  • Split the traffic between frequency bands
23
Q

Fill in the blank: The AP connected to the WLC is often referred to as a _______.

Study These Flashcards
A

lightweight AP.

24
Q

What feature allows specific TCP and UDP ports to be opened on a wireless router?

Study These Flashcards
A

Port forwarding.

25
True or False: The wireless router configuration can typically be accessed through a command-line interface.
False
26
What is the typical use case for a small office and home wireless router?
Provide WLAN security, DHCP services, and NAT.
27
What is the significance of the 'Network Summary' page on the WLC?
Provides an overview of configured wireless networks, APs, and active clients.
28
What should you do to ensure there are no overlapping channels in a WLAN configuration?
Configure the channel carefully.
29
What is the benefit of splitting wireless traffic between the 2.4 GHz and 5 GHz bands?
It helps manage traffic by using two separate wireless networks.
30
What type of traffic is the 2.4 GHz band suitable for?
Basic Internet traffic that is not time-sensitive.
31
Why is the 5 GHz band ideal for streaming multimedia?
It is much less crowded and has more channels, reducing interference.
32
What is the first step in the WLAN troubleshooting process?
Identify the Problem.
33
What command can be used to confirm the network configuration on a PC?
ipconfig
34
What should you check if a wireless client is not connecting?
Confirm power to all devices and inspect links for bad connectors.
35
Fill in the blank: The process of analyzing and resolving network issues is called _______.
troubleshooting
36
What should be done after determining the cause of a WLAN issue?
Establish a Plan of Action to Resolve the Problem and Implement the Solution.
37
What is the purpose of a RADIUS server in WLAN user authentication?
To provide authentication, accounting, and auditing (AAA) services.
38
True or False: Dual-band routers typically use different network names for the 2.4 GHz and 5 GHz bands.
False
39
What should be done to improve the range of a wireless network?
Ensure the router or AP location is free of obstructions.
40
What is the role of SNMP in WLAN management?
To monitor the network and forward log messages to the SNMP server.
41
What does QoS stand for and what is its purpose?
Quality of Service; it prioritizes certain traffic types over others.
42
What is the default key management protocol for WPA2 Enterprise WLAN?
802.1X
43
List the steps to configure a new interface on a WLC.
* Create a new interface * Configure VLAN name and ID * Configure port and interface address * Configure DHCP server address * Apply and Confirm * Verify Interfaces
44
What should be done periodically to maintain wireless routers and APs?
Verify and upgrade firmware.
45
What is the first action you should take when setting up a wireless router?
Change the username and password.
46
Fill in the blank: Lightweight APs (LAPs) communicate with a WLAN controller using _______.
Lightweight Access Point Protocol (LWAPP)
47
What can be used to extend the range of a wireless network beyond approximately 45 meters indoors?
Add wireless access points.
48
What is the purpose of the DHCP scope in WLAN configuration?
To allocate IP addresses to devices on the network.
49
What should you do if the wireless connection is performing poorly?
Check the channel settings and for interference.
50
What is the significance of documenting findings in the troubleshooting process?
It is important for future reference.
51
What is NAT and what does it do?
Network Address Translation; it converts private IPv4 addresses to internet-routable IPv4 addresses.
