NVIDIA-Certified Professional AI Networking Sample Questions (Q64-Q69):

NEW QUESTION # 64
You suspect there might be connectivity issues in your InfiniBand fabric and need to perform a comprehensive check. Which tool should you use to run a full fabric diagnostic and generate a report?

  • A. perfquery
  • B. ibnetdiscover
  • C. ibdiagnet
  • D. taping

Answer: C

Explanation:
The ibdiagnet utility is a fundamental tool for InfiniBand fabric discovery, error detection, and diagnostics. It provides comprehensive reports on the fabric's health, including error reporting, switch and Host Channel Adapter (HCA) configuration dumps, various counters reported by the switches and HCAs, and parameters of devices such as switch fans, power supply units, cables, and PCI lanes. Additionally, ibdiagnet performs validation for Unicast Routing, Adaptive Routing, and Multicast Routing to ensure correctness and a credit- loop-free routing environment.
Reference Extracts from NVIDIA Documentation:
* "The ibdiagnet utility is one of the basic tools for InfiniBand fabric discovery, error detection and diagnostic. The output files of the ibdiagnet include error reporting, switch and HCA configuration dumps, various counters reported by the switches and the HCAs."
* "ibdiagnet also performs Unicast Routing, Adaptive Routing and Multicast Routing validation for correctness and credit-loop free routing."


NEW QUESTION # 65
In Cumulus Linux, which technology enables the ability to provide active-active redundancy to servers, without the need for direct inter-switch links?

  • A. MLAG
  • B. VSS
  • C. EVPN Multi-homing

Answer: C

Explanation:
EVPN Multi-homingenablesactive-active redundancy without inter-switch linksby usingoverlay routing over VXLAN and distributed control plane using BGP EVPN.
From the officialNVIDIA Cumulus Linux EVPN Multihoming Documentation:
"EVPN multihoming allows multiple Top-of-Rack (ToR) switches to connect to the same server while maintaining full layer-2 redundancy without the need for inter-switch links or traditional MLAG configuration." Key benefits:
* Simplified topology (no ISL/peer-link needed)
* BGP-based control plane
* Fast convergence
* Active-active links per host NIC
Incorrect Options:
* MLAGrequires ISL between switches and peer-link configuration.
* VSS(Virtual Switching System) is a Cisco term, not supported in NVIDIA networking.

NEW QUESTION # 66
In a multi-tenant InfiniBand environment managed by UFM, you need to configure access controls to prevent unauthorized users from altering the fabric configuration. Which method is used within UFM to manage user access and ensure authorized modifications only?

  • A. Digital Certification Management (DCM)
  • B. Role-Based Access Control (RBAC)
  • C. Virtual Network Segmentation (VNS)
  • D. Network Access Control (NAC)

Answer: B

Explanation:
Role-Based Access Control (RBAC)is implemented within NVIDIA's Unified Fabric Manager (UFM) to manage user permissions effectively. RBAC allows administrators toassign roles to users, each with specific permissions, ensuring that only authorized individuals can make changes to the fabric configuration. This structured approach to access control enhances security by limiting the potential for unauthorized modifications and streamlines the management of user privileges across the network.

NEW QUESTION # 67
Which of the following tools in Cumulus Linux is specifically useful for detecting and differentiating microbursts from regular network congestion?
Pick the 2 correct responses below

  • A. SNMP polling at 5-minute intervals
  • B. ASIC monitoring with millisecond-level granularity
  • C. Monthly network utilization reports
  • D. What Just Happened (WJH) feature for packet drop analysis

Answer: B,D

Explanation:
In Cumulus Linux, microbursts are short-lived, high-volume traffic bursts that often go undetected by coarse- grained monitoring like SNMP.
The two tools specifically used for this purpose are:
* What Just Happened (WJH)
"WJH provides real-time packet drop visibility and classifies drops by reason (e.g., congestion, ACLs, etc.), enabling microburst detection."
* ASIC monitoring at millisecond granularity
"Deep telemetry is enabled via the switch ASIC, which provides sub-second counters that capture microburst patterns otherwise missed by SNMP." Incorrect Options:
* AandCprovide low-frequency sampling, insufficient for microbursts which last milliseconds.

NEW QUESTION # 68
You are setting up PKey memberships for different tenants in an InfiniBand network. You want to ensure that some tenants have limited communication capabilities. Which PKey membership type allows members to communicate with full members but not with other members of the same type?

  • A. Isolated membership
  • B. Limited/partial membership
  • C. Restricted membership
  • D. Full membership

Answer: B

Explanation:
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.
