CWT-101 Part 2

What is the term used to describe the process of restricting network access based on a device's MAC address?

• WEP

• Shared Key Authentication

• Hidden SSIDs

• MAC filtering

Which factor can contribute to low data rates in a wireless network?

• Interference

• Co-channel interference (CCI)

• Configuration errors

• Low signal strength

What AP configuration option is often thought to provide security but actually provides no security because of the simple spoofing attack weakens it?

• MAC filtering

• WEP

• Shared Key Authentication

• SSID hiding

What can be configured in some client devices to encourage them to use 5 GHz APs whenever they are available?

• Band preference

• Gaming mode

• Band selection

• Roaming aggressiveness

You have configured a WLAN profile on a client computer for a hidden SSID network. The SSID operates in both 2.4 GHz and 5 GHz. The profile never connects or even attempts to connect. What is the most likely configuration error in the profile or on the computer?

• Wrong passphrase

• Band selection is configured for 5 GHz-only

• Wrong SSID

• Band selection is configured for 2.4 GHz-only

Which configuration option allows control over the transmit power of an 802.11 AP?

• PHY and frequency band support

• Single-band vs. dual-band

• Output power control

• Operational modes

Which configuration option allows an 802.11 AP to receive power through an Ethernet connection?

• PHY and frequency band support

• Single-band vs. dual-band

• Output power control

• PoE support

Which of the following devices is typically characterized by its portability and touchscreen interface?

• Laptops

• Tablets

• Mobile phones

• Desktops

What is the term used to describe the roaming feature that is not implemented or enabled in a wireless network, causing mobility problems?

• Configuration errors

• Improper network settings

• Unsupported fast roaming methods

• Non-implemented roaming features

In addition to modulation, coding, and spatial streams, what has the most impact on available data rates in a WLAN link?

• Output power of the AP above 100 mW

• Output power of the client above 100 mW

• Antenna gain above 11 dBi

• Channel width
