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

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.

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.

TheGPU in the MI300X systemis secured withT15 Torx screws, requiring aT15 Torx Bitfor removal.

Option A (Incorrect):T20 Torx Bit istoo largefor GPU screws.

Option B (Incorrect):Security Torx Bit isnot requiredfor standard GPU removal.

Option C (Correct):T15 Torx Bit is the correct toolfor removing GPU screws.

Option D (Incorrect):Phillips Head Screwdriversdo not fit the GPU screws.

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.

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.

Supermicro ships systems with aunique BMC passwordfor security purposes. Thispassword is printed on a label located on the bottom side of the system cover.

Option A (on the I/O module tag)is incorrect as the tag typically containsnetwork interface informationrather than credentials.

Option B (using the system model number as a password)is incorrect because Supermicrodoes not use default passwords based on the model number.

Option C (on the bottom of the system)is close but not precise;the correct location is the bottom side of the system cover.

Option D (label on the bottom side of the system cover)is correct, as stated in theSupermicro IPMI and BMC login documentation​.

Security Recommendation:Upon first login,Supermicro strongly recommends changing the default BMC password immediatelyfor security reasons​.

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.

TheSUM (Supermicro Update Manager) command to check basic system informationis:

css

CopyEdit

sum.exe -i 10.1.1.100 -p ADMIN -u ADMIN -c checkbasicinfo

Option A (Correct):This is the correct syntax for retrievingbasic system information using SUM.

Option B (Incorrect):The syntaxis incorrect and will not execute properly.

Option C (Incorrect):The"checksysteminfo" command is not validin SUM.

Option D (Incorrect):"checkassetinfo"retrieves system asset details, not basic system information.

TheROCm System Management Interface (rocm-smi)is the recommended tool forgathering AMD GPU informationfrom the server.

Option D (Correct):

sudo rocm-smi -a displaysall available GPU information.

sudo rocm-smi showsbasic GPU stats.

Option A (Incorrect):These arenot valid ROCm commands.

Option B (Incorrect):"rockm-smc" and "rockm-bug.report.txt"do not exist in ROCm.

Option C (Incorrect):"rocm-gpu" and "rocm-baseboardgpu" arenot standard AMD diagnostic commands.
