Question 1
A Fleet Command system administrator wants to create an organization user that will have the following rights: For locations - read only For Applications - read/write/admin For Deployments - read/write/admin For Dashboards - read only What role should the system administrator assign to this user?
Show answer and explanation
Correct answer: A. Fleet Command Operator
The Fleet Command Operator role provides the exact permission structure described: read-only access to Locations, read/write/admin access to Applications, read/write/admin access to Deployments, and read-only access to Dashboards. This role is designed for users who need operational control over applications and deployments while maintaining restricted visibility of the broader infrastructure.
Why the other options are wrong
- B. Fleet Command Admin has full admin rights across all areas, exceeding the specified limited access requirements.
- C. Fleet Command Supporter typically has limited troubleshooting and support permissions, not the admin-level access needed for Applications and Deployments.
- D. Fleet Command Viewer is read-only across all areas and cannot provide the write/admin permissions required for Applications and Deployments.
Question 2
An organization only needs basic network monitoring and validation tools. Which UFM platform should they use?
Show answer and explanation
Correct answer: D. UFM Pro
UFM Pro is designed to meet basic network monitoring and validation requirements with essential monitoring capabilities. It provides foundational tools for network visibility and performance validation without the advanced features and complexity of enterprise, telemetry-focused, or AI-powered solutions, making it the appropriate choice for organizations with basic monitoring needs.
Why the other options are wrong
- A. UFM Enterprise is a comprehensive solution with advanced features designed for large-scale deployments, exceeding basic monitoring needs.
- B. UFM Telemetry is specialized for deep data collection and analytics rather than basic network monitoring and validation.
- C. UFM Cyber-AI focuses on security and artificial intelligence capabilities, which are not required for basic network monitoring and validation.
Question 3
Your organization is running multiple AI models on a single A100 GPU using MIG in a multi-tenant environment. One of the tenants reports a performance issue, but you notice that other tenants are unaffected. What feature of MIG ensures that one tenant's workload does not impact others?
Show answer and explanation
Correct answer: A. Hardware-level isolation of memory, cache, and compute resources for each instance.
MIG (Multi-Instance GPU) ensures that each tenant's workload operates in complete isolation through hardware-level separation of memory, cache, and compute resources. This hardware-enforced isolation guarantees that one tenant's performance issues or resource consumption cannot affect other tenants running on the same physical GPU, preventing cross-tenant performance impact.
Why the other options are wrong
- B. Dynamic resource allocation would allow resources to shift between tenants, which would enable one tenant's workload to impact others rather than prevent it.
- C. Shared memory access across instances would directly cause interference between tenants and is the opposite of what prevents performance issues in MIG.
- D. Automatic scaling based on workload size does not provide isolation and could actually enable one tenant's scaling to consume resources needed by others.
Question 4
A new researcher needs access to GPU resources but should not have permission to modify cluster settings or manage other users. What role should you assign them in Run:ai?
Show answer and explanation
Correct answer: A. L1 Researcher
L1 Researcher is the appropriate role for a researcher who needs GPU resource access without administrative capabilities. This role grants compute resource access while restricting cluster configuration and user management permissions. Department Administrator and Application Administrator have broader administrative permissions beyond what is needed, while Research Manager typically has oversight responsibilities rather than individual researcher access patterns.
Why the other options are wrong
- B. Department Administrator has permissions to manage cluster settings and user access, which exceeds the researcher's requirements.
- C. Application Administrator manages application-level configurations and resources, not individual researcher GPU access.
- D. Research Manager is a supervisory role focused on managing other researchers and projects, not individual contributor access.
Question 5
When troubleshooting Slurm job scheduling issues, a common source of problems is jobs getting stuck in a pending state indefinitely. Which Slurm command can be used to view detailed information about all pending jobs and identify the cause of the delay?
Show answer and explanation
Correct answer: A. scontrol
scontrol is the primary command for viewing detailed information about jobs and identifying why they are in pending state. It provides comprehensive job state details including scheduling constraints and resource availability issues. sacct shows accounting information for completed or running jobs but is less detailed for real-time pending state diagnosis, while sinfo displays node and partition status rather than specific job-level information.
Why the other options are wrong
- B. sacct is designed for job accounting history and completed job information, not for troubleshooting pending job delays.
- C. sinfo shows partition and node status information but does not provide job-specific details needed to identify why a particular job is pending.
Question 6
What must be done before installing new versions of DOCA drivers on a BlueField DPU?
Show answer and explanation
Correct answer: A. Uninstall any previous versions of DOCA drivers.
Uninstalling previous versions of DOCA drivers is the essential prerequisite before installing new versions on a BlueField DPU to prevent conflicts and ensure clean driver state. Re-flashing firmware is not required for every driver update as firmware and driver versions are managed separately, disabling network interfaces is not necessary during DOCA driver installation, and the host system reboot typically occurs after installation rather than before it.
Why the other options are wrong
- B. Firmware re-flashing is not required for each DOCA driver update and would unnecessarily complicate the installation process.
- C. Network interface disabling is not a prerequisite for DOCA driver installation and may not be operationally feasible.
- D. While rebooting may be needed after installation, it is not a prerequisite before beginning the DOCA driver installation process.
Question 7
A Slurm user needs to display real-time information about the running processes and resource usage of a Slurm job. Which command should be used?
Show answer and explanation
Correct answer: C. sstat -j <job(.step)></job(.step)>
sstat is the command specifically designed to display real-time information about running processes and resource usage for active Slurm jobs. It provides detailed metrics on CPU, memory, and other resource consumption for running job steps. smap shows job layout information, scontrol shows job state but not real-time resource usage details, and sinfo displays partition and node information rather than individual job process metrics.
Why the other options are wrong
- A. smap displays spatial job layout information on nodes but does not provide real-time resource usage metrics for running processes.
- B. scontrol shows job configuration and state information but lacks the real-time process and resource usage details that sstat provides.
- D. sinfo displays partition and node status information, not job-specific or process-level resource usage data.
Question 8
Which two (2) ways does the pre-configured GPU Operator in NVIDIA Enterprise Catalog differ from the GPU Operator In the public NGC catalog? (Choose two.)
Show answer and explanation
Correct answer: A, D. It is configured to use a prebuilt vGPU driver image; It is configured to use the NVIDIA License System (NLS).
The pre-configured GPU Operator in the NVIDIA Enterprise Catalog is configured to use a prebuilt vGPU driver image for streamlined enterprise deployments, and it integrates with the NVIDIA License System (NLS) for enterprise licensing requirements. Mixed Strategies support exists in both versions for Kubernetes deployments, the Datacenter driver is installed in both public and enterprise versions, and Network Operator is a separate component not specific to the enterprise GPU Operator configuration.
Why the other options are wrong
- B. Mixed Strategies for Kubernetes is supported by the GPU Operator in both public and enterprise catalogs, not unique to the enterprise version.
- C. The NVIDIA Datacenter driver is installed by both the public and enterprise GPU Operator versions.
- E. Network Operator is a separate component that can be deployed independently and is not an inherent difference in the enterprise GPU Operator configuration.
Question 9
You are managing multiple edge AI deployments using NVIDIA Fleet Command. You need to ensure that each AI application running on the same GPU is isolated from others to prevent Interference. Which feature of Fleet Command should you use to achieve this?
Show answer and explanation
Correct answer: C. Multi-Instance GPU (MIG) support
Multi-Instance GPU (MIG) support in NVIDIA Fleet Command enables partitioning a single GPU into isolated instances, allowing multiple AI applications to run on the same physical GPU without interference. This provides hardware-enforced isolation and resource guarantees for each application. Remote Console is for system access, Secure NFS supports data storage, and over-the-air updates manage software deployment, none of which provide application isolation on shared GPUs.
Why the other options are wrong
- A. Remote Console provides remote access to edge systems but does not provide GPU-level application isolation.
- B. Secure NFS support handles networked file storage and data redundancy, not application isolation on GPUs.
- D. Over-the-air updates manage application and firmware deployment, not GPU resource isolation between running applications.
Question 10
You are deploying AI applications at the edge and want to ensure they continue running even if one of the servers at an edge location fails. How can you configure NVIDIA Fleet Command to achieve this?
Show answer and explanation
Correct answer: C. Enable high availability for edge clusters.
High availability configuration in NVIDIA Fleet Command ensures that edge cluster applications continue running despite individual server failures by implementing redundancy and failover mechanisms across cluster nodes. Secure NFS provides data redundancy at the storage layer but not application failover, over-the-air updates manage software deployment without providing failure recovery, and MIG handles GPU partitioning rather than cluster-level fault tolerance.
Why the other options are wrong
- A. Secure NFS support addresses data redundancy and storage resilience, not application availability during server failures.
- B. Over-the-air updates manage application deployment and updates but do not provide failover mechanisms for handling server failures.
- D. MIG partitions GPUs into isolated instances for resource management but does not handle server-level failover or high availability.
What people say about the full NCP-AIO pack 5.0 from 2

Question 11
You are configuring cloudbursting for your on-premises cluster using BCM, and you plan to extend the cluster into both AWS and Azure. What is a key requirement for enabling cloudbursting across multiple cloud providers?
Show answer and explanation
Correct answer: C. You must configure separate credentials for each cloud provider in BCM to enable their use in the cluster extension process.
Each cloud provider (AWS and Azure) has distinct authentication mechanisms and credential formats. BCM requires administrators to configure separate credentials for each provider independently to enable proper authentication and resource provisioning across multiple cloud environments during cluster extension.
Why the other options are wrong
- A. Credentials cannot be replicated across providers; each provider has unique authentication requirements and credential structures.
- B. AWS and Azure do not share credential formats; they require separate authentication mechanisms and API keys.
- D. BCM does not automatically detect or configure cloud provider credentials; this requires explicit administrative configuration for security and compliance.
Question 12
You are managing a Kubernetes cluster running AI training jobs using TensorFlow. The jobs require access to multiple GPUs across different nodes, but inter-node communication seems slow, impacting performance. What is a potential networking configuration would you implement to optimize inter-node communication for distributed training?
Show answer and explanation
Correct answer: D. Use InfiniBand networking between nodes to reduce latency and increase throughput for distributed training jobs.
InfiniBand networking is the industry standard for high-performance distributed training because it provides significantly lower latency and higher throughput compared to Ethernet. For GPU-intensive distributed TensorFlow jobs requiring frequent inter-node communication, InfiniBand reduces communication bottlenecks that would otherwise limit training performance and scalability.
Why the other options are wrong
- A. Increasing replicas does not address inter-node communication latency; it may worsen the problem by creating more communication overhead.
- B. While jumbo frames improve Ethernet efficiency, standard Ethernet cannot match InfiniBand's latency and throughput characteristics required for distributed training.
- C. A dedicated storage network addresses data persistence, not inter-node communication for real-time distributed training synchronization.
Question 13
You are managing a Slurm cluster with multiple GPU nodes, each equipped with different types of GPUs. Some jobs are being allocated GPUs that should be reserved for other purposes, such as display rendering. How would you ensure that only the intended GPUs are allocated to jobs?
Show answer and explanation
Correct answer: A. Verify that the GPUs are correctly listed in both gres.conf and slurm.conf, and ensure that unconfigured GPUs are excluded.
Proper GPU allocation control requires that GPUs be correctly configured in both gres.conf (generic resources configuration) and slurm.conf (main Slurm configuration). Unconfigured GPUs must be explicitly excluded from Slurm's resource management so they cannot be allocated to jobs. This prevents unintended GPU allocation and ensures only designated GPUs are available for job scheduling.
Why the other options are wrong
- B. nvidia-smi is a monitoring tool and cannot be used to assign GPUs to jobs; assignment happens through Slurm configuration.
- C. Reinstalling drivers does not address the configuration issue; the problem is in Slurm's resource management setup, not driver detection.
- D. Requesting more GPUs does not solve the underlying configuration problem and wastes resources unnecessarily.
Question 14
You are configuring networking for a new AI cluster in your data center. The cluster will handle large-scale distributed training jobs that require fast communication between servers. What type of networking architecture can maximize performance for these AI workloads?
Show answer and explanation
Correct answer: D. Use InfiniBand networking to provide low-latency, high-throughput communication between servers in the cluster.
InfiniBand is the optimal networking technology for AI clusters requiring large-scale distributed training. It provides significantly lower latency and higher throughput compared to standard Ethernet, which is critical for the intensive inter-node communication patterns in distributed deep learning. InfiniBand's performance advantages directly translate to faster model convergence and better training efficiency for AI workloads.
Why the other options are wrong
- A. Leaf-spine topology improves scalability but does not address the fundamental bandwidth and latency limitations of standard Ethernet for AI workloads.
- B. Out-of-band management networks are separate from compute networks and do not affect application performance between compute nodes.
- C. Multiple standard Ethernet connections improve bandwidth but cannot match InfiniBand's latency and throughput characteristics needed for AI training.
Question 15
You are using BCM for configuring an active-passive high availability (HA) cluster for a firewall system. To ensure seamless failover, what is one best practice related to session synchronization between the active and passive nodes?
Show answer and explanation
Correct answer: B. Use heartbeat network for session synchronization between active and passive nodes.
The heartbeat network is the dedicated communication channel used between active and passive nodes in high-availability clusters to synchronize critical state information, including session data. This heartbeat network enables the passive node to remain synchronized with the active node's state so that upon failover, the passive node can assume the active role without session loss or service interruption.
Why the other options are wrong
- A. Different zone names would actually create conflicts and prevent proper failover coordination between active and passive nodes.
- C. Using different firewall models introduces inconsistency and potential compatibility issues; both nodes should have matching configurations.
- D. Manual synchronization procedures introduce delays and human error, defeating the purpose of seamless automatic failover.
Question 16
A data scientist is training a deep learning model and notices slower than expected training times. The data scientist alerts a system administrator to inspect the issue. The system administrator suspects the disk IO is the issue. What command should be used?
Show answer and explanation
Correct answer: B. iostat
The iostat command provides detailed disk input/output statistics including read/write rates, I/O utilization, and throughput metrics. It is the appropriate tool for diagnosing disk IO performance issues during training. tcpdump captures network packets unrelated to disk performance, nvidia-smi monitors GPU metrics, and htop shows process CPU and memory usage but not disk IO details.
Why the other options are wrong
- A. tcpdump captures network traffic and does not provide disk IO performance metrics.
- C. nvidia-smi monitors GPU utilization and memory but not disk IO performance.
- D. htop shows CPU and memory usage but lacks detailed disk IO performance statistics.
