RFID Certification Exam

Question No: 41 – (Topic 0)

One reason that the ultra high frequency (UHF) Electronic Product Code (EPC) Gen 2 air interface protocol functions well in a multiple interrogator environment is that it:

  1. allows interrogator manufactures to interpret regional regulations.

  2. requires double sideband (DSB) modulation.

  3. allows for separate transmit and receive channels.

  4. allows the tags to initiate communications.

Answer: C

Question No: 42 – (Topic 0)

An RFID interrogator is reading tags on cartons on a conveyor and cartons are directed to the proper truck by electrically-operated gates on the conveyor line. A carton reaches the first gate in one-half second. The decision to open a gate is BEST made by:

  1. a universal serial bus (USB) connection to the remote server.

  2. an interrogator with WiFi capability.

  3. an Ethernet connection to the remote server. D.

  4. an interrogator with an edge-server capability.

Answer: D

Question No: 43 – (Topic 0)

Which of the following anti-collision protocols uses a synchronous scheme?

  1. Binary tree

  2. Digital modulation

  3. ALOHA

  4. Stream cipher

Answer: A

Question No: 44 – (Topic 0)

A manufacturer of canned goods arranges tagged cartons in nine stacks nine high on a pallet. The passive ultra high frequency (UHF) tags on the center stack have a high failure rate on reads. Which of the following would be the BEST way to improve the read rate?

  1. Arrange the antennas on the top so they focus on the center stack.

  2. Double the number of antennas using 50-ohm splitters.

  3. Add a second interrogator running at 13.56 MHz.

  4. Read the individual cartons as the pallet is being built.

Answer: D

Question No: 45 – (Topic 0)

Question No: 49 – (Topic 0)

If an interrogator and associated antennas are located at a dock door with a desk for the traffic coordinator, which of the following may be a concern?

  1. The traffic coordinator may be over exposed to radio waves.

  2. The traffic coordinator would rely too much on the RFID data.

  3. The forklift drivers would have access to the interrogator data.

  4. The interrogator could not be connected to the network.

Answer: A

Question No: 50 – (Topic 0)
