SMI300XE MI300X Expert (SMI300XE) Certification Exam Questions and Answers

A failed GPU in the Supermicro MI300X system can be identified usingthe warning light indicator. Supermicro systems includeLED diagnostic indicatorsthat display the operational status of various components, including GPUs. When a GPU malfunctions, the system will trigger an alert that is displayed as a warning light on the GPU tray or the server chassis. This allows technicians to visually identify the faulty GPU without requiring extensive hardware testing.

Discoloration (A)is not a reliable method of identifying a failed GPU as it would require physical degradation, which is uncommon.

Serial numbers (B)andPart numbers (C)are used for inventory tracking but do not indicate functional status.

Warning lights (D)are the recommended method, as documented in the system health monitoring section of Supermicro's documentation, which detailsLED indicators and diagnostic lights for system status monitoring​.

When working withSupermicro MI300X GPU systems, it ishighly recommendedtomap or take a pictureof cable connections before disconnection.

Reasons:

Ensuring Proper Reconnection→ NVMe backplanes have multiplecritical connections(MCIO cables, power cables, data lanes, and SAS connections). Misplacing any of these cables could cause:

Boot failures

Drive detection issues

Performance degradation

Avoiding Errors in Cable Routing→ Supermicro documentation states thatimproperly routed cables can obstruct airflow, potentially leading tooverheatingin high-performance systems.

Easing Future Troubleshooting→ If issues arise after reassembly, aphoto or cable mapallows engineers toquickly verifywhether cables werereconnected properly.

This best practice isofficially recommendedinSupermicro’s service and installation guidelinesfor NVMe backplanes.

Theevent logis the primary source of information for identifyingsystem issues and their exact timing. TheIPMI event logrecords all critical system alerts, includinghardware failures, temperature warnings, power issues, and other critical errors.

Option A (Incorrect):GPU memory specifications do not provide issue tracking information.

Option B (Correct):Theevent log tracks all system events and errors, making it essential for troubleshooting.

Option C (Incorrect):Subnet masks relate to network configurations and do not provide system issue tracking.

Option D (Incorrect):Last login attempts show security logs but arenot related to hardware or system issues.

This question is a duplicate ofQuestion No. 20. The correctWindows executable file extension for SUM is .exe.

Option A (Correct):SUM on Windows is executed using .exe.

Option B (Incorrect):.sh is a script file format for Linux, not Windows.

Option C (Incorrect):.txt files contain textand cannot execute commands.

Option D (Incorrect):"binary" is not a valid file extension for SUM execution on Windows.

The ROCm softwarerequires at least one GPU to function. It can stilloperate with up to 2 missing GPUs, butif 3 or more GPUs are missing, ROCm commands will fail.

Option A (Incorrect):ROCmfails if 3 GPUs are missing.

Option B (Incorrect):The software can function withmore than 1 GPU missing.

Option C (Correct):ROCmcan still execute commands if only 1 or 2 GPUs are missing.

Option D (Incorrect):At least 1 GPUmust be detected for ROCm to work.

TheROCm command outputprovides essentialGPU performance metrics:

Option A (Correct):Energy CountertracksGPU power consumption.

Option B (Correct):Firmware DetailsprovideGPU firmware version.

Option C (Correct):Temperatureshowsreal-time thermal readings.

Option E (Correct):Power DrawgivesGPU power usage data.

Option D (Incorrect):vBiosis not a key ROCm statistic.

Option F (Incorrect):Socket Type is not includedin ROCm statistics.
