RFID Certification Exam

Question No: 101 – (Topic 1)

A container yard has been upgraded with an active RFID system for tracking containers moving to different locations within the yard. Recently, the system monitor has observed a decrease in interrogator reporting. Which of the following may be the cause of this change?

  1. The yard manager installed wooden walls to separate various areas within the yard.

  2. The company has introduced a new line of propane-powered forklifts in the yard.

  3. The 50 workers in the container yard were issued cellular telephones for reporting container conditions to the yard manager.

  4. The temperature in the area has dropped to 0 C (32 F) and this temperature has been sustained for the past 2 weeks.

Answer: D

Question No: 102 – (Topic 1)

When installing equipment into a proposed interrogation zone based on the site diagram, a technician observes that the cooling fans at the dock doors are directly in the way of the dock stands requiring installation. Which of the following actions should the technician take?

  1. Cancel the installation because there are physical constraints preventing them from completing the job as designed.

  2. Remove the fans; install the dock stands, and then remount the fans to the dock stands to complete the job.

  3. Remove the fans and place them on the floor just outside of the proposed interrogation zone.

  4. Contact the project manager to arrange a meeting with site management and determine the best solution.

Answer: D

Question No: 103 – (Topic 1)

When installing a conveyor tunnel, antennas should be placed:

  1. on the same side of the conveyor with radiation patterns not overlapping away from the conveyor path.

  2. underneath the conveyor with radiation patterns overlapping in the area under the conveyor.

  3. around the conveyor with radiation patterns overlapping away from the conveyor path.

  4. around the conveyor with radiation patterns overlapping along the conveyor path.

Answer: D

Question No: 104 – (Topic 1)

A container yard unloads 40 foot (12.4 meter) containers from a freighter. As a container is lifted, the active tag is read, however other tags still on containers on the freighter are also read. A solution to this problem would be to:

  1. install circularly polarized antennas.

  2. install Yagi antennas.

  3. trigger the tag read at some other point.

  4. increase the power level of the interrogator.

Answer: C

Question No: 105 – (Topic 1)

An interrogator that supports four antennas only has two antennas attached and the customer reports that the interrogator is not functioning. Which of the following may be the cause of the problem?

  1. Terminators were not placed on the unused antenna ports.

  2. The interrogator must have four antennas connected to operate.

  3. The antennas were of different polarization.

  4. The antenna#39;s gain was too high causing the interrogator to overheat.

Answer: A

Question No: 106 – (Topic 1)

A warehouse dealing with quantities of RF absorbing material has a portal using a single antenna with reflective panels on all sides. The totes used to transport the material have tags mounted to one end and are run through the portal in random orientations. Not all tags are being read. Which of the following would be the BEST way to correct this problem?

  1. Add antennas on the other side of the portal.

  2. Increase the radiated power.

  3. Change the type of tag used.

  4. Reduce the amount of material in the tote.

Answer: A

Question No: 107 – (Topic 1)

The higher frequency ranges of RFID [e.g. ultra high frequency (UHF), microwave] offer which of the following as advantages over the lower frequencies? (Select TWO).

  1. There are fewer regulatory issues.

  2. There is greater range.

  3. They work well around water or body tissue.

  4. They have a higher data rate.

Answer: B,D

Question No: 108 – (Topic 1)

Ultra high frequency (UHF) output power is measured as:

  1. Effective Isotropic Radiated Power (EIRP).

  2. decibels.

  3. decibels per meter.

  4. Effective Radiated Power (ERP).

Answer: A

Question No: 109 – (Topic 1)

A container yard unloads 40 foot (12.4 meter) containers from a freighter. As a container is lifted, the active tag is read, however other tags still on containers on the freighter are also

read. A solution to this problem would be to:

  1. install circularly polarized antennas.

  2. install Yagi antennas.

  3. trigger the tag read at some other point.

  4. increase the power level of the interrogator.

Answer: C

Topic 2, B

B

Question No: 110 – (Topic 2)

A conveyor system has cartons that may be standing up or lying on the side. Which of the

following antenna configurations would work BEST for reading these cartons? (Select TWO).

  1. A linear antenna.

  2. Two linear antennas, one vertical and the other horizontal.

  3. An isotropic antenna.

  4. A circularly polarized antenna.

Answer: B,D
