Wireless Communication Technologies Quiz

Sherry needs to suggest a technology that can enable smartphones or laptops to control multiple devices like speakers, mice, etc., within a 100-meter distance. The device should also be connected without any wired connection. Which technology should Sherry suggest?

• NFC technology can be used to connect mobile devices to speakers

• WLANs can be used to connect mobile devices to speakers

• RFID technology can be used to connect laptop mouse without any wired connection

• Bluetooth technology can be used to connect devices without any wired connection

Which technology under wireless communication is an integrated circuit that securely stores information used to identify and authenticate an IoT device?

• Narrowband IoT

• Subscriber identity module

• Zigbee

• Cellular IoT baseband

In which type of RFID attack can unauthorized users listen to communications between RFID tags and readers?

• Eavesdropping

• Data theft

• Unauthorized tag access

• Fake tags

Which type of wireless attack is designed to capture wireless transmissions coming from legitimate users?

• Evil twin

• Wireless denial of service attacks

• Rogue access point

• Jamming

Which type of attack can give an attacker access to a device and allow them to copy personal information using an unauthorized radio frequency connection?

• Bluesnarfing

• NFC attack

• Bluejacking

• RFID attack

Which wireless probe can be designed by configuring a laptop computer to scan and record wireless signals within its range at regular intervals and report the information to a centralized database?

• Dedicated probes

• Wireless device probe

• Access point probe

• Desktop probe

Why are jamming attacks generally rare?

• The transmitter is not very powerful and must be close to the target

• They can't get around new IEEE amendments that fully protect WLANs

• They require expensive, sophisticated equipment

• They can't identify WLAN RF signals from other device signals

What is the difference between protecting against eavesdropping and protecting against a man-in-the-middle (MITM) attack when working with devices with NFC?

• Eavesdropping can be prevented by configuring in a pairing method so only one side can send and the other can receive it at a time, while MITM can be prevented by using strong passwords and PINs.

• Eavesdropping can be prevented by turning off NFC while in public, while MITM attack can be protected by using strong passwords and PINs.

• Eavesdropping can be prevented by strong passwords and PINs, while MITM attacks can be prevented by being aware of one's surroundings while using NFC technology.

• Eavesdropping can be prevented by being aware of one's surroundings while using NFC technology, while MITM attack can be prevented by configuring in a pairing method so only one side can send and the other can receive it at a time.

Which of the following attacks, exemplified by jamming and RTS duration field attacks, do attackers use intentional interference to flood the RF spectrum with enough interference to prevent a device from effectively communicating with the AP?

• Wireless denial of service attacks

• Intercepting wireless data

• Disassociation attack

• Evil twin

Which of the following statements correctly defines jamming?

• An attacker intentionally floods the RF spectrum with extraneous RF signal "noise" that creates interference and prevents communications.

• An attacker tries to mimic an authorized AP, so a user's mobile device such as a laptop or tablet unknowingly connects to the evil twin instead.

• An attacker creates false deauthentication or disassociation management frames that appear to come from another client device, causing the client to disconnect from the AP.

• An attacker circumvents the security protections in the company's network, accessing the network behind the firewall.
