Troubleshooting Wireless Flashcards
Which of the following recommendations should you follow when placing access points to provide wireless
access for users within your company building?
Place access points in the basement.
Place multiple access points in the same area.
Place access points near outside walls.
Place access points above where most clients are.
Place access points above where most clients are.
A user on your network has been moved to another office down the hall. After the move she calls you
complaining that she has only occasional network access through her wireless connection. Which of the
following is most likely the cause of the problem?
The client system has moved too far away from the access point.
An SSID mismatch between the client and the WAP.
An SSID mismatch between the client and the server.
The encryption level has been erroneously set back to the default setting.
The client has incorrect WEP settings.
The client system has moved too far away from the access point.
A user calls to report that she is experiencing intermittent problems while accessing the wireless network
from her laptop computer. While talking to her, you discover that she is trying to work from the coffee room
two floors above the floor where she normally works.
What is the most likely cause of her connectivity problem?
The user has not yet rebooted her laptop computer while at her new location.
The user is out of the effective range of the wireless access point on her floor.
The wireless network access point on the users normal floor has failed.
The user has not yet logged off and back on to the network while at her new location.
The user needs a new IP address because she is working on a different floor.
The user is out of the effective range of the wireless access point on her floor.
You are implementing a wireless network inside a local office. You require a wireless link to connect a laptop
in the administrator’s office directly to a system in the sales department. In the default configuration, the
wireless AP uses a 360-dispersed RF wave design. After installed, the signal between the two systems is weak
as many obstacles interfere with the signal.
Which of the following strategies could you try to increase signal strength?
Increase the RF setting on the client system
Replace the directional antenna with an Omni-directional antenna
Increase the RF setting on the AP
Replace the Omni-directional antenna with a directional antenna
Increase the RF power on the isotropic antenna
Replace the Omni-directional antenna with a directional antenna
You have been hired to troubleshoot a wireless connectivity issue for two separate networks located within a
close proximity. Both networks use a WAP from the same manufacturer and all settings, with the exception of
SSIDs, remain configured to the default.
Which of the following might you suspect as the cause of the connectivity problems?
The SSIDs of the two server systems match
WEP overlap
Overlapping channels
Crosstalk between the RF signals
The SSIDs of the two client systems match
Overlapping channels
While configuring a new 802.119 wireless network, you discover another wireless network within range that
uses the same channel ID that you intend to use. Which of the following strategies are you most likely to
adopt in order to avoid a conflict between the networks?
Use 802.11b instead of 802.11g.
Use a different Channel ID.
Use the same channel ID, but configure your wireless network to use WEP.
Use the same channel ID, but configure a different SSID.
Use a different Channel ID.
You are troubleshooting a wireless connectivity issue in a small office. You determine that the 2.4GHz
cordless phones used in the office are interfering with the wireless network transmissions.
If the cordless phones are causing the interference, which of the following wireless standards could the
network be using? (Select two.)
Bluetooth
802.11b
Infrared
802.3a
802.11a
Bluetooth
802.11b
Your organization uses an 802.11b wireless network. Recently, other tenants installed the following
equipment in your building:
-A wireless television distribution system running at 2.4 GHz
-A wireless phone system running at 5.8 GHz
-A wireless phone system running at 900 MHz
-An 802.11a wireless network running in the 5.725 - 5.850 GHz frequency range
0 An 802.11j wireless network running in the 4.9 - 5.0 GHz frequency range
Since this equipment was installed, your wireless network has been experiencing significant interference.
Which system is to blame?
The 900 MHz wireless phone system
The 802.11j wireless network
The 802.11a wireless network
The 5.8 GHz wireless phone system
The wireless TV system
The wireless TV system
You are setting up a wireless hotspot in a local coffee shop. For best results, you want to disperse the radio
signals evenly throughout the coffee shop.
Which of the following types of antennas would you use on the AP to provide a 360-degree dispersed wave
pattern?
Multi-directional
Multi-point
Uni-directional
Directional
Omni-directional
Omni-directional
You have decided to conduct a business meeting at a local coffee shop. The coffee shop you chose has a
wireless hotspot for its customers who want Internet access.
You decide to check your e-mail before the meeting begins, but when you open the browser you cannot gain
Internet access. Other customers are on the Internet and because you use a wireless connection at work, you
are sure your laptops wireless adapter works.
What is the likely cause of the problem?
WAP is out of range
PPP is not configured correctly
Different LAN protocols used
Mismatched SSID
Mismatched SSID
After installing a new 2.4Ghz cordless phone system in your office, you notice that wireless network
performance is adversely affected. Which of the following wireless networking standards are you most likely
to be using? (Select two.)
- 1 1a
- 1 lg
