質問 1：
Which of the following is an attribute of an inductively coupled system [e.g. low frequency (LF), high frequency (HF)] that a capacitively coupled [e.g. ultra high frequency (UHF), uW] system does not have?
A. Inductive dipole antenna.
B. Inductive coil antenna.
C. Capacitive material in which to store power.
D. Capacitive power circuitry.
正解：B
質問 2：
An RFID system is to be used in a conveyor belt operation where single boxes with RFID labels are to be read. Which of the following types of antennas would be MOST effective?
A. Isotropic
B. Circularly polarized
C. Horizontally polarized linear
D. Vertically polarized linear
正解：B
質問 3：
When reviewing the data content of a tag, the data length is less than expected. The MOST likely cause of this would be that:
A. software filters are set too low.
B. power to the interrogator is shorting out.
C. the battery pack in the interrogator needs to be changed.
D. a tag constructed for fewer bits is being read.
正解：D
質問 4：
Which of the following RFID tags would be BEST for inconspicuous tagging of assets containing a maximum of eight bytes of data and are inductively coupled?
A. Passive 13.56 MHz tag that is affixed to the asset and camouflaged requiring continuous loop interrogation.
B. Passive Gen 2 tag requiring line of sight backscatter interrogation.
C. Active 433.92 MHz tag with strategically installed fixed interrogators.
D. Active 433.92 MHz tag requiring modulated backscatter interrogation.
正解：A
質問 5：
Desktop industrial RFID-enabled bar code printers handle an inoperative tag by:
A. sending an error to the host.
B. ejecting the label.
C. ignoring it and continuing.
D. printing 'void' or some other marking on the label.
正解：D
質問 6：
Using a spectrum analyzer, it is determined that the source of interference in a passive ultra high frequency (UHF) system is the vehicle-mounted computers. The computers are operating in spread-spectrum 915 MHz mode. Which of the following would be the MOST efficient method of resolving this situation?
A. Replace the radio cards in the computer terminals with 802.11 radio cards and change the access points to support 802.11 operation as well.
B. Surround the computer terminals with a shield so the terminals cannot emit signals into the interrogation zones.
C. Remove the computer terminals, replacing them with computers that operate in a different frequency range and update the wireless network to support this change.
D. Replace the radio cards in the computer terminals with 802.11 radio cards and the computer terminals will be able to communicate over the existing access points.
