C) Passive QR codes
D) Passive RFID codes

Accepted Answer

Active RFID tags use internal batteries for power and can broadcast radio waves to a reader, allowing for longer range communication compared to passive tags, which do not have their own power source.

Question 9

________ rely entirely on readers for their power, are less expensive, and can be read only up to 20 feet.
A) Active QR codes
B) Active RFID codes
C) Passive QR codes
D) Passive RFID codes

Accepted Answer

Passive RFID codes rely entirely on readers for their power, making them less expensive, and they have a limited read range, typically up to 20 feet.

Question 10

The adoption of ________ has been an important factor in the development of the Internet of Things.
A) IPv2
B) IPv4
C) IPv6
D) IPv8

Accepted Answer

IPv6 has been crucial for the development of the Internet of Things (IoT) due to its ability to provide a vastly larger number of IP addresses compared to IPv4, accommodating the massive growth in internet-connected devices.

Question 11

_________ is a system in which any object, natural or manmade, has a unique identity and is able to send and receive information over a network without human interaction.
A) A mobile portal
B) A wireless network
C) The IoT
D) UWB

Accepted Answer

The IoT, or Internet of Things, refers to the system where objects have unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

Question 12

Paul is travelling to a new client and he receives messages about traffic along the way. Paul is using _______.
A) a mobile wallet
B) location services
C) intrabusiness applications
D) a mobile portal

Accepted Answer

Location services provide real-time traffic updates, which would be useful for Paul while traveling to a new client.

Question 13

_________ allows manufacturers to attach tags with antennas and computer chips on goods and then track their movement through radio signals.
A) NFC
B) RFID
C) UWB
D) XML

Accepted Answer

RFID (Radio-Frequency Identification) technology involves using tags with antennas and computer chips that can be attached to items. These tags can then be tracked through radio signals, allowing for the monitoring of the movement of goods.

Question 14

Which of the following is FALSE of QR codes?
A) QR codes are larger than bar codes because they store information both horizontally and vertically.
B) QR codes are more resistant to damage than bar codes.
C) QR codes can be read from any direction or angle.
D) QR codes can store much more information than bar codes.

Accepted Answer

QR codes are not inherently larger than bar codes because they store information both horizontally and vertically. The size of a QR code can vary and is dependent on the amount of information it contains, not the orientation of data storage. QR codes are designed to efficiently use space in both dimensions, which allows them to store a significant amount of information in a relatively small area.

Question 15

Donald and his tech team are working on creating a new smartphone. They want users to have the ability to set individual messages and ringtones. Which feature of mobility are they concerned with?
