Which network mode can typically be used for both 2.4 GHz and 5 GHz clients?

802.11ax

How many total channels (non-overlapping) are available for 802.11a wireless networks?

What is the "peak data rate" for 5G cellular technology?

Up to 20 Gbps

Your company security policy states that wireless networks are not to be used because of the potential security risk they present.

One day you find that an employee has connected a wireless access point to the network in his office.

Which type of security risk is this?

Rogue access point

Which of the following is a frequency defined by 802.11 committees for wireless networking?

2.4 GHz

Which of the following 802.11 wireless standards operates in the 6-GHz frequency band?

802.11ax

Which wireless networking component is used to connect multiple APs together?

WDS

You are designing an update to your client's wireless network. The existing wireless network uses 802.11b equipment, which your client complains runs too slowly. She wants to upgrade the network to run up to 600 Mbps.

Due to budget constraints, your client wants to upgrade only the wireless access points in the network this year. Next year, she will upgrade the wireless network boards in her users' workstations. She has also indicated that the system must continue to function during the transition period.

Which 802.11 standard will work BEST in this situation?

802.11n

Which of the following measures will make your wireless network invisible to the casual attacker performing war driving?

Disable SSID broadcast

Which of the following causes EMI

fluorescent lights

You, as a network administrator, have been contracted to set up a WLAN network so that you can transmit data directly to the other nodes without any intervening connectivity device. Which of the following will you use for this purpose?

Ad Hoc

Your manager has asked you to set up four independent APs and configure them with the same SSID, channel, and IP subnet. What should you enable to accomplish this?

Roaming

Which of the following is NOT a security concern with BYOD?

External threats

Which technology is used by the 802.11ac standard to increase network bandwidth?

Eight MIMO radio streams

Which of the following purposes do wireless site surveys fulfill? 

Identify existing or potential sources of interference

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 is out of the effective range of the access point

Which of the following is true of a wireless network SSID?

Multiple Input, Multiple Output: Uses multiple antennas for transmitting and receiving

What does channel bonding offer

Combining 2 non overlapping channels into one and offer double the speed

What GHz range does 802.11ax operate in

1-7.125

What are the three methods of wireless authentication

Open, WEP, EAP 802.1x

What bit encryption does WEP use

256
