Question 4
UnclassifiedWhich XID error code indicates NVLink training failure?
Correct answer: C
Explanation
XID 76 is the NVIDIA error code associated with NVLink training failure. In NVIDIA XID reporting, this code identifies a problem during link initialization, so it points to NVLink training rather than a generic GPU fault.
Why each option is right or wrong
A. XID 72
B. XID 74
C. XID 76
NVIDIA’s XID event table assigns code 76 to an NVLink link-training failure, i.e., the interconnect did not complete initialization during bring-up. In the XID taxonomy, this is a specific fabric/link error rather than a general GPU exception, so the diagnostic code for failed NVLink training is 76.
D. XID 79
