CMT CMT Documentation & Compliance 2 — Questions and Answers
Question 1: What does the Electronic Serial Number (ESN) identify, and why is it relevant to repair technicians?
- It is a unique hardware identifier used historically by CDMA carriers; checking it reveals if the device is clean for activation (Correct answer)
- It is the same as the IMEI on all devices
- It identifies the SIM card, not the device
- It is only used for warranty registration
Correct answer: It is a unique hardware identifier used historically by CDMA carriers; checking it reveals if the device is clean for activation
ESNs were used by CDMA carriers (Verizon, Sprint) before IMEI standardization; a bad ESN means the device cannot be activated.
Question 2: A repair shop must comply with which regulation when disposing of lithium-ion batteries?
- EPA and state hazardous waste regulations, as lithium batteries are classified as hazardous materials (Correct answer)
- FCC Part 15 regulations only
- OSHA ergonomics standards
- FTC advertising regulations
Correct answer: EPA and state hazardous waste regulations, as lithium batteries are classified as hazardous materials
Lithium batteries contain materials regulated as hazardous waste and must be disposed of through certified recyclers.
Question 3: What is the purpose of OSHA's Hazard Communication Standard (HazCom) in a mobile repair shop?
- It requires that employees be informed about hazardous chemicals (such as solvents and adhesives) used in repairs through Safety Data Sheets (Correct answer)
- It governs customer privacy only
- It sets device repair pricing standards
- It certifies technicians for hazardous environments
Correct answer: It requires that employees be informed about hazardous chemicals (such as solvents and adhesives) used in repairs through Safety Data Sheets
HazCom (29 CFR 1910.1200) requires SDS availability and hazard labeling for all chemical products used in the workplace.
Question 4: What does a Certificate of Destruction (CoD) document in the context of mobile device repair?
- It certifies that a device's data has been securely and completely destroyed according to a defined standard (Correct answer)
- It confirms the physical destruction of a broken device screen
- It is a receipt for recycled materials
- It registers the device as stolen
Correct answer: It certifies that a device's data has been securely and completely destroyed according to a defined standard
A CoD is provided to customers when their device or data is permanently wiped to NIST or DoD standards for compliance.
Question 5: What is PCI DSS compliance relevant to in a mobile repair shop context?
- It applies if the shop processes credit card payments and requires secure handling of cardholder data (Correct answer)
- It governs how parts are stored
- It is a standard for device waterproofing
- It applies only to banks, not retail businesses
Correct answer: It applies if the shop processes credit card payments and requires secure handling of cardholder data
Any business accepting credit cards must comply with PCI DSS standards for secure payment processing.
Question 6: Why should a repair technician document part serial numbers used in a repair?
- To trace parts in case of a recall, verify warranty compliance, and confirm authenticity of components used (Correct answer)
- It is only required for insurance claims
- To register the parts with the manufacturer
- To meet IRS depreciation requirements
Correct answer: To trace parts in case of a recall, verify warranty compliance, and confirm authenticity of components used
Part-level documentation enables recall tracking, warranty substantiation, and demonstrates quality assurance.
