NCP-AII Question 50
Select 3You are tasked with configuring the network fabric ports for hosts in an NVIDIA AI infrastructure deployment. The environment includes NVIDIA BlueField DPUs and NVIDIA Mellanox switches. Which of the following steps should you take to ensure proper network setup?
- A
Enable RoCE (RDMA over Converged Ethernet) on the network switches.
- B
Configure Quality of Service (QoS) policies to prioritize AI/ML traffic.
- C
Ensure that Jumbo Frames are disabled to avoid MTU mismatches.
- D
Assign VLANs for management, storage, and compute traffic segregation.
- E
Disable LLDP (Link Layer Discovery Protocol) to reduce network overhead.
Show answer and explanation
Correct answers: A, B, D
Explanation
Properly setting up network fabric ports for hosts in an NVIDIA AI infrastructure involves enabling key features like RoCE, configuring QoS for traffic prioritization, and using VLANs for traffic segregation. These steps ensure optimal performance, low latency, and secure communication within the infrastructure. Misconfigurations like disabling Jumbo Frames or LLDP can lead to performance degradation or troubleshooting difficulties.
- A. Correct.
Enabling RoCE on the network switches is essential for leveraging RDMA, which provides high-performance and low-latency interconnects for AI workloads.
- B. Correct.
Configuring QoS policies helps optimize the performance of AI/ML traffic by prioritizing it over less critical traffic, ensuring predictable performance.
- C. Incorrect.
Disabling Jumbo Frames is incorrect. Jumbo Frames should typically be enabled to support efficient data transfer for large AI workloads, as they reduce overhead.
- D. Correct.
Assigning VLANs for different traffic types ensures proper traffic segregation, improving security and performance within the AI infrastructure.
- E. Incorrect.
Disabling LLDP is incorrect. LLDP helps in network topology discovery and is useful for troubleshooting and ensuring proper connectivity.
