In InfiniBand networks,P_Keys (Partition Keys)control communication boundaries. Each port can belong to one or more partitions with eitherfullorlimitedmembership.

From NVIDIA InfiniBand Documentation (Partitioning and P_Keys):

"A limited (or partial) membership permits a port to communicate only with other ports in the same partition that have full membership. It cannot communicate with other limited members, even if they are in the same P_Key partition."

This makes limited/partial membership ideal formulti-tenant security, where tenant ports can reach infrastructure ports (full members) butnotother tenant ports (limited members).

Incorrect Options:

A & Bare not valid InfiniBand P_Key types.

C (Full membership)allows unrestricted communication within the same partition.

NVIDIA NetQ is a network operations tool that provides real-time visibility and automated validation of the network fabric. It helps in identifying misconfigurations, monitoring network health, and ensuring that the fabric meets the required specifications for AI workloads.​

UFM Telemetry: Provides real-time monitoring and analysis of network performance, collecting data such as port counters and cable information to assess the health and efficiency of the network.

UFM Enterprise: Focuses on comprehensive network management and optimization, enabling administrators to monitor, operate, and optimize InfiniBand scale-out computing environments effectively.

UFM Cyber AI: Detects and mitigates network security threats by analyzing telemetry data to identify anomalies and potential security issues within the network infrastructure.​

Reference Extracts from NVIDIA Documentation:

"UFM Telemetry provides real-time monitoring and analysis of network performance."​

"UFM Enterprise is a powerful platform for managing InfiniBand scale-out computing environments."​

"UFM Cyber-AI enhances the benefits of UFM Telemetry and UFM Enterprise services by detecting and mitigating network security threats."​

InDPU Mode, theARM cores on BlueFieldown theNIC data path, while still allowing thehost system to access the DPU OS (via OOB or virtio).

From NVIDIA BlueField Documentation:

"In DPU Mode, the data path is offloaded to the BlueField Arm cores, enabling advanced security and networking functions, while still allowing host access to the BlueField OS."

This is different from:

NIC Mode: Data path controlled by host, ARM cores inactive.

Separated Host Mode: Complete isolation; host cannot access DPU OS.

Restricted Mode: Limited host access to DPU OS, but without full offload capabilities.
