NCP-AII Question 48
Select 4You are tasked with configuring the network fabric ports for an NVIDIA AI infrastructure. The setup requires high-speed data transfer between compute nodes and storage, as well as redundancy and fault tolerance. Which configuration steps should you prioritize when setting up the network fabric ports?
- A
Ensure that the ports support RDMA over Converged Ethernet (RoCE) for low-latency data transfer.
- B
Configure VLAN tagging to segregate network traffic based on workload types.
- C
Enable Port Mirroring on all ports to monitor the network traffic in real-time.
- D
Set up Link Aggregation Control Protocol (LACP) to increase bandwidth and provide redundancy.
- E
Allocate ports to a dedicated storage network to avoid congestion on the main network.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
When setting up network fabric ports for NVIDIA AI infrastructure, it is crucial to focus on configurations that optimize performance, reduce latency, and ensure fault tolerance. RDMA over Converged Ethernet (RoCE) and VLAN tagging improve communication efficiency, while LACP and dedicated storage networks enhance reliability and prevent congestion. Port Mirroring, while useful for monitoring, is not a primary requirement for this setup.
- A. Correct.
RDMA over Converged Ethernet (RoCE) is essential for AI workloads as it ensures low-latency, high-throughput communication, which is critical for distributed training and inference tasks.
- B. Correct.
VLAN tagging helps isolate traffic for different workloads, improving performance and ensuring security.
- C. Incorrect.
Port Mirroring is used for debugging or monitoring purposes and is not a priority for setting up network fabric ports for AI workloads.
- D. Correct.
Link Aggregation Control Protocol (LACP) is critical for combining multiple network connections into one to increase bandwidth and provide redundancy, ensuring data transfer reliability.
- E. Correct.
Dedicated storage networks help prevent congestion on the primary network fabric, ensuring smooth data flow for compute and storage communication.
