CET Registry Operations & Management 2 — Questions and Answers
Question 1: Which FCC rule part governs the equipment authorization (registry) procedures for most intentional radiators sold in the US?
- Part 2
- Part 15 (Correct answer)
- Part 68
- Part 90
Correct answer: Part 15
FCC Part 15 governs unlicensed intentional radiators and their authorization/registry requirements.
Question 2: When an electronics technician updates a repair record in a calibration registry, which data element is most critical for traceability?
- The technician's employee number
- The NIST-traceable standard reference number (Correct answer)
- The customer's billing address
- The color of the equipment chassis
Correct answer: The NIST-traceable standard reference number
NIST-traceable standard reference numbers establish an unbroken chain of traceability in calibration records.
Question 3: In equipment registry management, what does the acronym 'EIN' typically stand for in the context of FCC device identification?
- Electrical Interference Number
- Equipment Identification Number (Correct answer)
- External Interface Node
- Electronic Input Node
Correct answer: Equipment Identification Number
EIN (Equipment Identification Number) uniquely identifies a registered device within FCC and similar regulatory databases.
Question 4: A technician discovers that a registered piece of test equipment has exceeded its calibration interval. What is the correct first action?
- Continue using it and note the discrepancy later
- Tag it out-of-service and update the registry (Correct answer)
- Recalibrate it immediately without recording anything
- Dispose of it per hazmat procedures
Correct answer: Tag it out-of-service and update the registry
Equipment past its calibration due date must be immediately tagged out-of-service and its status updated in the registry before any further use.
Question 5: Which of the following is NOT typically stored in an electronics equipment registry entry?
- Manufacturer and model number
- Serial number
- Calibration due date
- Operator's personal home address (Correct answer)
Correct answer: Operator's personal home address
Equipment registries record technical and maintenance data about the equipment itself, not personal addresses of operators.
Question 6: Under FCC regulations, how long must a grantee retain equipment authorization records after the product is discontinued?
- 1 year
- 2 years (Correct answer)
- 5 years
- Indefinitely
Correct answer: 2 years
FCC rules require grantees to retain equipment authorization records for a minimum of 2 years after the product is discontinued.
Question 7: In a preventive maintenance registry, 'MTBF' is used to schedule service intervals. What does MTBF stand for?
- Mean Time Between Failures (Correct answer)
- Maximum Throughput Before Fault
- Minimum Time Before Function
- Mean Total Bandwidth Factor
Correct answer: Mean Time Between Failures
MTBF (Mean Time Between Failures) is a reliability metric used to predict and schedule preventive maintenance intervals.
