Which term refers to a facility that manufactures microprocessors under a validated supply chain to prevent tampering?

• A. Source Authenticity
• B. Trusted Foundry
• C. MAC Flood
• D. Switching Loop

Answer: (B)

The concept tested is securing the hardware supply chain for critical components. A trusted foundry is a fabrication facility whose manufacturing processes, suppliers, and controls are validated and audited to ensure the integrity of the microchips from design through production and packaging. Operating in a trusted foundry helps prevent tampering, hardware Trojans, or counterfeit parts by enforcing strict provenance, secure handling, and traceability throughout the supply chain. Other terms don’t fit because they don’t describe a manufacturing facility with validated supply-chain security. Source Authenticity is more about proving where something came from and may not imply a secure production environment. MAC Flood and Switching Loop are networking terms related to attacks and topology issues, not to secure semiconductor fabrication.
