最新的 NVIDIA-Certified Professional NCP-AIN 免費考試真題 (Q42-Q47):

問題 #42
How is congestion evaluated in an NVIDIA Spectrum-X system?

A. By assessing the physical distance between network devices.
B. By measuring the number of connected devices in the network.
C. By analyzing the egress queue loads ensuring all ports are well-balanced.
D. By monitoring the CPU and power usage of network devices.

答案：C

解題說明：
In NVIDIA Spectrum-X, congestion is evaluated based on egress queue loads. Spectrum-4 switches assess the load on each egress queue and select the port with the minimal load for packet transmission. This approach ensures that all ports are well-balanced, optimizing network performance and minimizing congestion.

問題 #43
How does Spectrum-X achieve network isolation for multiple tenants?

A. By implementing physical network segmentation.
B. Using manual configuration of access control lists (ACLs).
C. By assigning unique IP address ranges to each tenant.
D. By implementing a Layer 3 Virtual Network Identifier (L3VNI) per VRR

答案：D

解題說明：
Spectrum-X achieves network isolation in multi-tenant environments by implementing Layer 3 Virtual Network Identifiers (L3VNIs) per Virtual Routing and Forwarding (VRF) instance. This approach allows each tenant to have a separate routing table and network segment, ensuring that traffic is isolated and secure between tenants.
Reference Extracts from NVIDIA Documentation:
* "Spectrum-X enhances multi-tenancy with performance isolation to ensure tenants' AI workloads perform optimally and consistently."

問題 #44
You are troubleshooting InfiniBand connectivity issues in a cluster managed by the NVIDIA Network Operator. You need to verify the status of the InfiniBand interfaces. Which command should you use to check the state and link layer of InfiniBand interfaces on a node?

A. ibstat -d mlx5_X
B. ip link show dev ib0
C. ifconfig ib0
D. rdma show devices

答案：A

解題說明：
To check the status and link layer of InfiniBand interfaces, the ibstat command is used. For example:
ibstat -d mlx5_0
This command provides detailed information about the InfiniBand device, including its state (e.g., Active), physical state (e.g., LinkUp), and link layer (e.g., InfiniBand).

問題 #45
A major cloud provider is designing a new data center to support large-scale AI workloads, particularly for training large language models. They want to optimize their network architecture for maximum performance and efficiency.
Why is a rail-optimized topology considered a best practice for AI network architecture in this scenario?

A. It provides optimal GPU-to-GPU communication and reduces network interference between flows.
B. It maximizes the number of network hops to increase data redundancy.
C. It simplifies network management by using a single large switch for all connections.
D. It prioritizes north-south traffic over east-west traffic for better internet connectivity.

答案：A

解題說明：
A rail-optimized topology is designed to enhance GPU-to-GPU communication by connecting each GPU's Network Interface Card (NIC) to a dedicated rail switch. This configuration ensures predictable traffic patterns and minimizes network interference between data flows, which is crucial for the performance of large-scale AI workloads, such as training large language models. By reducing contention and latency, this topology supports efficient and scalable AI training environments.
Reference Extracts from NVIDIA Documentation:
* "Rail-optimized network topology helps maximize all-reduce performance while minimizing network interference between flows."
* "A Rail Optimized Stripe Architecture provides efficient data transfer between GPUs, especially during computationally intensive tasks such as AI Large Language Models (LLM) training workloads, where seamless data transfer is necessary to complete the tasks within a reasonable timeframe."

問題 #46
In order to configure RoCE on a Cumulus switch, which command should be used?

A. nv qos roce enable on
B. nv set qos roce enable on
C. nv roce qos enable on
D. nv set roce qos enable on

答案：B

解題說明：
To enable RDMA over Converged Ethernet (RoCE) on a Cumulus switch, the correct command is:
nv set qos roce enable on
This command configures the Quality of Service (QoS) settings to support RoCE, ensuring that the necessary parameters for lossless Ethernet are applied.
Reference: NVIDIA Cumulus Linux Documentation - RDMA over Converged Ethernet (RoCE)

問題 #47
