RFID Certification Exam

Question No: 71 – (Topic 1)

Interrogation zones that are found to be interfering with an existing system can BEST be resolved by doing which of the following?

  1. Shielding the zone with a reflective or absorptive material.

  2. Replacing the existing components that are interfering.

  3. Turning oft the RFID system.

  4. Upgrading the RFID system to Electronic Product Code (EPC) Class 1 Gen 2 specifications.

Answer: A

Question No: 72 – (Topic 1)

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?

  1. 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.

  2. Remove the computer terminals, replacing them with computers that operate in a different frequency range and update the wireless network to support this change.

  3. Surround the computer terminals with a shield so the terminals cannot emit signals into the interrogation zones.

  4. 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.

Answer: D

Question No: 76 – (Topic 1)

A large number of antennas are being damaged at the dock doors of an existing installation. Upon further inspection, the technician discovers that forklift operators are hitting the antennas because they are 2 inches (5 centimeters) in front of the protective pylons/ballards. Which of the following would be the BEST solution?

  1. Move the dock stands so they are further out of the travel path than the protective equipment installed.

  2. Re-install the antennas so they protrude into the travel path further than the dock stands

  3. Remove the dock stands and install them somewhere else in the operation.

  4. Replace the dock stands with smaller, less obtrusive dock stands.

Answer: A

Question No: 78 – (Topic 1)

An animal identification system is used in feedlots and transfer gates are equipped with 135 kHz

interrogators and are of a size to support one animal. When two animals attempt to get through at the same time, a problem occurs because the:

  1. 135 kHz systems do not have anti-collision algorithms.

  2. 135 kHz interrogator system is broken because of the congestion.

  3. animals expand the gates to a size where the second animal cannot be read.

  4. animals are moving too slowly to be read only once.

Answer: A

Question No: 79 – (Topic 1)

In package tracking systems, read-only tags are unable to be used because the destination postal code is not contained within the tag. Read-only tags have been proposed to work in a manner so as to read the read-only tag and then access the package tracking company#39;s database to determine the appropriate sorting, based on the postal code within the database. Which of the following would be a reason that this would not be successful?

  1. Read-only tags are not able to be reused and re-write tags can be re-used.

  2. Distribution of the read-only tags to the drivers requires that each driver have a specific sequence of numbers in the tag.

  3. When recording the destination information at package pickup it is feared that the wrong postal code will be entered.

  4. Using a reference number instead of the postal code for sorting depends upon a communications link that is not completely reliable.

Answer: D

Question No: 80 – (Topic 1)

When installing an RFID interrogator on a forklift, which of the following would be the BEST means of ensuring proper grounding on the forklift?

  1. Refer to the equipment manuals.

  2. Ground the interrogator to the frame.

  3. Use a volt meter to test for ground.

  4. Connect the antenna ground to the battery.
