Which command can be checked Atlas 300 (3000) Whether the accelerator card is in place?

Question

Options

• A1spci | grep'npu'
• B1spci | grep'd100'
• C1spci grep'atlas'
• Datlas info

• A

• B

• C
  3% (1)
• D

Explanation

Option B (lspci | grep 'd100') is correct because the Atlas 300 (3000) accelerator card is identified in the PCI device list using the hardware identifier d100, which maps to Huawei's NPU chip model; piping lspci through grep 'd100' filters PCI bus output to confirm the card's physical presence.

Option A fails because 'npu' is a generic architectural term, not an actual PCI device string-lspci reports vendor/device IDs, not category labels like "npu." Option C is syntactically broken: it's missing the pipe character (|), so the shell would pass 'atlas' as a filename argument to lspci rather than grep-filtering its output. Option D (atlas info) is not a valid system command; no standard utility by that name exists for hardware detection.

Memory tip: Think of D100 = Detect 100 (Atlas)-the "d100" string is Huawei's device ID shorthand for this NPU family, just as NVIDIA cards show up under their own IDs. When in doubt on hardware detection questions, look for the specific device ID grep, not a generic keyword or a broken pipe.
