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

TheAGFHC tool for Ubuntumust be installed in the/opt/AMD/AGFHCdirectory.

Option A (Incorrect):The/tmp/directory istemporary storageand is not used forapplication installations.

Option B (Incorrect):/windows/user/desktopis a Windows path and does not apply to Linux-based Ubuntu.

Option C (Incorrect):/usr/home/customer/AGFHCis not the correct standard directory for system-wide software.

Option D (Correct):/opt/AMD/AGFHCis the correct directory for installing AMD-related tools in Ubuntu.

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.

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.

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 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.

When theGPU tray is pulled out partially, itlocks in placetoprevent accidental removal or dropping. To fully remove it,two people must press down on the lever on each sidebefore continuing.

Option A (Correct):Thetray locks automaticallyto ensure safe removal, and two people are needed to press the unlock levers.

Option B (Incorrect):Thetray does not vibrate or flash redwhen released.

Option C (Incorrect):Thetray does not contain liquid components.

Option D (Incorrect):Thetray does not generate excessive heat upon removal.

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​.

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.

Thecorrect torque setting for GPU screwsin anMI300X systemis6-8 in-lbf. This ensures asecure fit without overtightening, which could damage the GPU.

Option C (Correct):6-8 in-lbf isthe recommended torquefor securing GPU screws.

Option A (Incorrect):4.2 in-lbf istoo low, leading to loose screws.

Option B (Incorrect):9.5 in-lbf istoo high, risking damage to the GPU mounting.

Option D (Incorrect):5.3 Nm isnot used for GPU mounting screws.
