NVIDIA AI Infrastructure Sample Questions (Q49-Q54):

NEW QUESTION # 49
Your tasked with updating both NVIDIA GPU drivers and DOCA drivers on a set of servers used for AI workloads. The environment previously had an older driver stack and custom kernel modules. What is the most important step to successfully upgrade the drivers without causing conflicts?

A. Uninstall all existing GPU and DOCA-related drivers and associated kernel modules before the new install.
B. Keep the older driver running alongside the new version in case you need to roll back the upgrade.
C. Update the GPU driver leaving the DOCA and OFED drivers unchanged as long as they are detecting the hardware properly.
D. Validate the driver version post-install since the fresh install will overwrite the legacy drivers.

Answer: A

Explanation:
NVIDIA AI infrastructure relies on a tightly coupled stack involving the GPU driver and theDOCA (Data Center Infrastructure-on-a-Chip Architecture)drivers, which include the OFED stack for InfiniBand.
When upgrading from an older version, "residue" from previous installations or custom kernel modules can cause version mismatches or symbol errors, preventing the new drivers from loading. The "100% verified" best practice is to perform a clean installation. This involves completely uninstalling the existing drivers (using apt-get purge or the .run file's --uninstall flag) and ensuring that kernel modules are removed from memory. This prevents conflict between the legacy nvidia.ko and the new version. Once the system is "clean," the new DOCA and GPU drivers can be installed as a matched set, ensuring that features like GPUDirect RDMA function correctly without being hindered by legacy configuration files.

NEW QUESTION # 50
You're deploying a large language model for inference using NVIDIA Triton Inference Server. You need to validate that the server can handle the expected query load while maintaining acceptable latency. Which tools and metrics are most relevant for this validation?

A. Utilize Triton's built-in metrics endpoint to track latency, throughput, and request queue length.
B. Use 'nvidia-smi' to monitor GPIJ utilization and memory usage.
C. All of the above
D. Check CPU utilization using 'top'
E. Employ a load testing tool (e.g., 'locust' , 'JMeter') to simulate client requests and measure response times.

Answer: C

Explanation:
Validating Triton's performance requires a comprehensive approach. Monitoring GPU usage with 'nvidia-smi', tracking Triton's internal metrics, using load testing tools to simulate real-world traffic, and monitoring CPU utilization are all important for identifying bottlenecks and ensuring optimal performance.

NEW QUESTION # 51
Which of the following statements regarding VXLAN (Virtual Extensible LAN) is MOST accurate in the context of data center networking for AI/ML workloads?

A. VXLAN reduces network overhead compared to traditional VLANs.
B. VXLAN primarily improves network security by encrypting all traffic.
C. VXLAN requires specialized hardware and cannot be implemented in software.
D. VXLAN provides Layer 2 connectivity across Layer 3 networks, enabling virtual machine mobility.
E. VXLAN is only suitable for small-scale networks due to its limited scalability.

Answer: D

Explanation:
VXLAN allows Layer 2 segments to be extended across Layer 3 infrastructure by encapsulating Ethernet frames within UDP packets. This enables virtual machine mobility across different subnets. VXLAN adds overhead due to encapsulation. While VXLAN can enhance security, encryption is not its primary function. It is highly scalable and can be implemented in both hardware and software.

NEW QUESTION # 52
A healthcare organization is deploying an AI system to analyze patient data for predictive diagnostics. The system must comply with strict data protection regulations such as HIPAA, ensuring that sensitive information remains confidential and secure. Considering the need for robust security measures, which combination of strategies should the organization prioritize to protect against data breaches and ensure regulatory compliance?

A. Use tokenization to replace sensitive data with non-sensitive tokens and employ multi-factor authentication (MFA) for system access.
B. Deploy data masking to obscure sensitive data during processing and use role-based access control (RBAC) to limit data access based on user roles.
C. Rely on asymmetric encryption for all communications and use data deduplication to minimize storage costs without additional security measures.
D. Implement symmetric encryption for all data at rest and rely solely on password-based access controls

Answer: B

Explanation:
Data masking protects sensitive patient information during processing by obscuring confidential values, while role-based access control limits access to only authorized users based on job responsibilities. Together, these controls help reduce exposure of protected health information and support compliance with strict healthcare data protection requirements.

NEW QUESTION # 53
You encounter a situation where an NVIDIA driver installation fails with the error message 'ERROR: Unable to load the kernel module 'nvidia.ko'. This may be because it was built for another kernel...'. Assuming the kernel headers are correctly installed, what is the most likely cause and solution?

A. The 'nouveau' driver is still loaded. Solution: Blacklist 'nouveau- and reboot.
B. The system is running out of disk space in '/tmp'. Solution: Free up space or remount S/tmp' with more space.
C. Secure Boot is enabled, and the NVIDIA kernel module is not signed. Solution: Sign the NVIDIA kernel module with a machine owner key (MOK).
D. The NVIDIA driver version is incompatible with the current kernel version. Solution: Install a compatible driver version.
E. The DKMS module build failed. Solution: Manually rebuild the DKMS module using 'dkms autoinstall'.

Answer: C,D,E

Explanation:
The error message indicates a mismatch between the driver and kernel. This can happen due to incompatibility, unsigned modules due to Secure Boot, or a failed DKMS build. Installing a compatible version, MOK signing, and rebuilding DKMS are valid solutions. While nouveau can interfere, the error message points specifically to a module loading problem, making the other options more likely. Lack of disk space is a less common, but possible, issue.
