What is spare‑part FRU tracking (recording field-replaceable unit serials/locations to maintain inventory accuracy and auditability)?

• A. Logging warranty information for FRUs.
• B. Maintaining field manual records for FRUs.
• C. Recording batch numbers for FRUs.
• D. Recording field-replaceable unit serials/locations to maintain inventory accuracy and auditability.

Answer: (D)

Spare-part FRU tracking is about keeping a precise, auditable record of each field-replaceable unit’s identity and where it is. Each FRU has a unique serial number, and you log that serial alongside its current location—whether it’s in a server, in a spare bin, or in repair. This creates end-to-end visibility: you know what spare parts you have, where they are, and the history of any moves or replacements. That visibility keeps inventory accurate because counts alone can be misleading if you can’t distinguish individual units. It also supports audits, since you can verify exactly which FRUs are in use, where they’ve been, and how they’ve been handled. Other options miss this level of granularity and traceability, focusing on warranty terms, manuals, or batch details instead of the unique identity and precise location of each FRU.
