The following quiz comes courtesy of CompTIA (the Computing Technology Industry Association, www.comptia.org), which offers RFID courses and certification.
# 1 The three types of RFID tags are:
- Ultra low frequency, low frequency and ultra high frequency (UHF).
- Real Time Locating System (RTLS), active and passive.
- Active, battery assisted active and passive.
- Active, passive, and semi-active.
# 2 When assisting with a site analysis for a passive high frequency (HF) smart shelf system, which of the following should have the LEAST affect upon design consideration?
- Shelves made of metal
- Tagging multiple items
- Tagging materials that are RF absorbent
- Tagging materials that are made of metal.
# 3 Lower frequency (LF) radio waves travel:
- Farther and penetrate solid substances more effectively.
- Less distance and have poor penetration on any solid substance.
- Farther but do not penetrate solid substances.
- Less distance but are highly effective on penetrating metal.
# 4 A systems architect is required to configure an active RFID system composed of interrogators placed to ensure coverage for all the RFID-tagged assets in a staging area. If the interrogators are placed too close together, this will create:
- An effective use of the real estate.
- A pre-positioning of extra interrogators should one become inoperable.
- Over interrogation of the tagged assets and unnecessary communication to and from the network.
- A redundant interrogation system necessary to assure all of the tagged assets have been read and reported via the network to the server.
# 5 Placement of a passive ultra high frequency (UHF) tag on the bottom of a metal container loaded on a pallet will cause which of the following read results?
- The tag will only be read if the bottom of the container is oriented to the antenna.
- The tag can only be read by a hand-held interrogator.
- The tag will be read regardless of orientation to the antenna.
- The tag can be read by a dock door portal interrogator.
