Which term describes a microprocessor manufacturing utility that is part of a validated supply chain?

• A. CAM Table
• B. Trusted Foundry
• C. Source Authenticity
• D. Port Security

Answer: (B)

A trusted foundry refers to a semiconductor fabrication facility that has been vetted and approved to operate as part of a validated supply chain. The idea is that this kind of facility follows stringent security controls, governance, and traceability measures so the microprocessors it produces can be trusted not to be tampered with or contaminated by counterfeit parts. This trust in the manufacturing environment covers processes, equipment, personnel, and handling throughout fabrication, testing, and packaging, providing assurance about provenance and integrity of the chips.

Other terms don’t fit this context. A CAM table is about mapping MAC addresses to switch ports, not about manufacturing security or supply chain validation. Port security is a network feature that restricts devices on a switch port, again unrelated to where or how chips are made. Source authenticity isn’t a standard descriptor for a manufacturing facility in this setting. So the concept best describing a microprocessor manufacturing utility within a validated supply chain is a trusted foundry.
