Supermicro SMI300XE MI300X Expert (SMI300XE) Certification Exam Exam Practice Test

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.

TheAGFHC Toolis specifically designed forSupermicro’s internal employeesandauthorized resellers (VARs). These users require access to diagnostic and firmware update tools that are restricted totrained personnel.

Option A (Correct):Internal Supermicro employeesuse this tool for system maintenance and diagnostics.

Option D (Correct):VARs (Value-Added Resellers)are authorized to use the tool forcustomer support and system integration.

Option B (Incorrect):GeneralSMC partners do not have accessto AGFHC.

Option C (Incorrect):End customers do not have accessto this tool.

When a GPU is not detected in theIPMI GUI reports, the recommended recovery method is topower off the system, reseat the GPU and heatsink, then power it back on and check the IPMI GUI for detection. This process ensures that the GPU is properly connected and making full contact with the system board.

Option A (pressing a GPU button for 5 seconds)is incorrect because there is no dedicated reinitialization button for GPU detection in Supermicro MI300X systems.

Option B (removing the GPU tray while powered on)is not advisable as it could cause damage to components.

Option D (reseating the motherboard tray)is unnecessary, as the issue is likely limited to GPU connectivity rather than a full system board issue.

Option C (powering off the system, reseating the GPU, and verifying in IPMI GUI)follows proper troubleshooting guidelines as documented in Supermicro’stroubleshooting and system health monitoring sections​.

The correct syntax for running recipes using theAGFHC toolis:

bash

CopyEdit

/agfhc -r alljvll.yml

This command runsa specified YAML recipe file (alljvll.yml)using the AGFHC tool in aLinux-based system.

Option A (Incorrect):Contains an incorrect flag (-r should be separated).

Option B (Incorrect):Uses incorrect flag format (-t -a), which is not part of AGFHC syntax.

Option C (Incorrect):Uses Windows-style .exe format, which is incorrect for Linux.

Option D (Correct):This follows thecorrect AGFHC syntaxfor running recipes in a Linux environment.

Toremove the GPU tray, you need toloosen two screwslocatedone on each side of the tray.

Option B (Correct):There isone screw on each sidethat must beloosenedbefore pulling the handles out/down.

Option A (Incorrect):The screwsare not only on the top.

Option C (Incorrect):The screwsare not only on the bottom.

Option D (Incorrect):Thereis no screw configurationwithone on top and one on the bottom.

Toaccess and replace a failed GPUin theMI300X system, you mustremove the GPU tray.

Option A (Incorrect):UpdatingAMD commandsdoes not physically grant access to GPUs.

Option B (Incorrect):LSPCIis used tolist PCI devices, not to physically access the GPUs.

Option C (Incorrect):SCC configurationis unrelated to physical GPU replacement.

Option D (Correct):Removing the GPU trayis the only way tophysically access and replace GPUs.

TheAGFHC toolis designed todiagnose and stress test system componentsin theMI300X platform, helpingidentify faultsin GPUs, CPUs, and system hardware.

Option A (Correct):AGFHC isused for diagnostics and stress testing.

Option B (Incorrect):The tool doesnot enable cross-platform GPU resource sharing.

Option C (Incorrect):While itinteracts with firmware, it doesnot update BIOS.

Option D (Incorrect):The tool isnot a support contact directory.

ForSupermicro MI300X GPU systems,removing the power supply unit (PSU) improperlycan lead to serious issues.

Why the red lock exists?

Thered locking mechanismensures that thePSU is properly securedin the system.

Before disengaging the PSU, thered lock must first be unlockedto avoid damage.

If you forcefully shift the release lever without unlocking the red lock:

B: The power supply unit will fail→ If the PSU is removed improperly, it can causeinternal damageto power connectors, resulting in PSUfailure or improper functioning.

C: You could permanently damage the lock on the power supply unit→ Thelocking mechanismis designed for smooth disengagement. Forcefully shifting the lever canbreak or warpthe lock, making itimpossible to secure the PSU back in place.

Incorrect Answers Explained:

A (All answers are correct)→ This is incorrect becausenot all answers are valid.

D (The PSU can no longer be secured into the tray)→ This happensonly if the lock is damaged, which is covered underoption C.

Supermicro’s official documentation clearly statesthatunlocking the red lock firstis a critical step before removing or replacing the PSU.

When handling theGPU tray, it should be placed ona flat, stable surfacetoprevent damage and ensure safety.

Option B (Correct):Aflat surfaceprovides stability and preventsaccidental damage or tipping.

Option A (Incorrect):Placing the trayon top of the chassiscan cause it tofall and sustain damage.

Option C (Incorrect):Thefloor is unsafedue tofoot traffic, riskingaccidental damage.

Option D (Incorrect):Acardboard box may not support the tray’s weight, making itunstable.
