NVIDIA NCP-AII Practice Test 40
Question 390
During an NVIDIA AI factory acceptance test, engineers discover: An operations team initiates BFB installation via a management controller but never checks post-flash boot state. Which TWO complementary elements are needed: the correct technical action and the strongest independent diagnostic evidence? Select TWO answers.
- Use the supported BFB deployment path with verified image compatibility, approved credentials and postboot checks.
- Choose supported MIG GPU-instance profiles and create matching compute instances with validated resource assignments.
- Inspect mode configuration, embedded OS status, host-visible functions, network policy and mode-transition logs.
- Treat any host Linux installation as proof that the separate BlueField embedded software was also provisioned correctly.
- Inspect DPU hardware generation, BFB package provenance, BMC job records, Arm boot logs and firmware versions.
Explanation
Correct Answers
A:This is an appropriate correction for BlueField boot image BFB provisioning and BMC: Use the supported BFB deployment path with verified image compatibility, approved credentials and postboot checks. Observed scenario: An operations team initiates BFB installation via a management controller but never checks post-flash boot state. The governing mechanism is: BlueField embedded software provisioning is a controlled device lifecycle separate from the host's ordinary OS image.
E:This is the direct operational evidence to investigate: Inspect DPU hardware generation, BFB package provenance, BMC job records, Arm boot logs and firmware versions. Observed scenario: An operations team initiates BFB installation via a management controller but never checks post-flash boot state.
Incorrect Answers
B:This alternative is relevant to MIG GPU and compute instance partition profiles but does not directly resolve the current BlueField boot image BFB provisioning and BMC issue: Choose supported MIG GPU-instance profiles and create matching compute instances with validated resource assignments. Observed scenario: An operations team initiates BFB installation via a management controller but never checks post-flash boot state.
C:This alternative is relevant to BlueField DPU embedded versus NIC ownership but does not directly resolve the current BlueField boot image BFB provisioning and BMC issue: Inspect mode configuration, embedded OS status, host-visible functions, network policy and mode-transition logs. Observed scenario: An operations team initiates BFB installation via a management controller but never checks post-flash boot state.
D:This tempting but unsafe shortcut is not a sufficient remediation for BlueField boot image BFB provisioning and BMC: Treat any host Linux installation as proof that the separate BlueField embedded software was also provisioned correctly. An operations team initiates BFB installation via a management controller but never checks post-flash boot state. BlueField embedded software provisioning is a controlled device lifecycle separate from the host's ordinary OS image.
