A. Circularly polarized
B. Yagi
C. Whip
D. Linearly polarized

Answer: D

Question 6.
RFID labels that were being printed correctly are now being printed with half the image area across two labels and the tags cannot be validated. 

Which of the following should the technician check FIRST?

A. Communications protocol
B. Print drivers
C. Sensor settings
D. Printer speed

Answer: C

Question 7.
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. Capacitive power circuitry.
B. Inductive dipole antenna.
C. Inductive coil antenna.
D. Capacitive material in which to store power.

Answer: C

Question 8.
A customer has an RFID system to sort packages by their destination in real time. When first installed, the system worked properly but now most packages are not going to the correct destination. 

Which of the following BEST describes the cause of this problem?

A. The customer is using a bad batch of tags.
B. Interrogator output power has degraded over time.
C. There are increased losses in the antenna cabling.
D. Sensors that control the interrogator were repositioned.

Answer: D

Question 9.
Within an office environment, a property manager must place an RFID tag on all assets with a value of greater than $100. The tags must cost less than $10 each; be able to store a maximum of one kilobit of data and read with a portable interrogator. When performing inventory, the manager is unable to move the assets to interrogate the tags. The RFID tags used should be applied to the front of the asset with an adhesive strong enough to prevent tag removal and be:

A. a Surface Acoustic Wave (SAW) tag.
B. a passive Class 0 tag.
C. a passive13.56 MHz tag.
D. an active Class 1 Gen 2 tag.

Answer: C

Question 10.
When using an RFID enabled printer to encode tags as they are being printed, which of the following determines the data being encoded?

A. The printer is encoding in a sequence guaranteeing unique data on each tag.
B. The software generating the print job.
C. The printer's firmware.
D. RFID enabled printers cannot encode RFID tags.

Answer: B

Question 11.
After viewing a site diagram, it is observed that the location of one of the interrogation zones is bisected by a steel door. 

Which of the following problems could this cause?

A. Having steel doors amplifies the interrogator signal.
B. Tags on the other side of the closed door would be read more than once.
C. If the door is closed, the interrogation area is reduced by one-half.
D. With the doors closed, the signal strength would overload the interrogator.
