Practice Questions: Initial Provisioning and High Availability Setup in NVIDIA InfiniBand Networking

These multiple-choice questions focus on key concepts related to the initial provisioning and high availability (HA) setup for NVIDIA InfiniBand networking environments, essential for the NVIDIA-Certified Professional: AI Networking exam.

1. Which of the following is the first step in the initial provisioning of an NVIDIA InfiniBand network?A) Configuring QoS policiesB) Assigning Partition Keys (PKeys)C) Establishing physical connectivity and verifying link statusD) Setting up adaptive routingCorrect answer: CExplanation: The initial provisioning begins with establishing physical connections and verifying link status to ensure the hardware is properly connected before configuring logical parameters.
2. What is the primary purpose of configuring Partition Keys (PKeys) during initial provisioning?A) To enable adaptive routingB) To segregate traffic for multi-tenancyC) To monitor bandwidth usageD) To implement high availability failoverCorrect answer: BExplanation: PKeys are used to create isolated partitions within the InfiniBand fabric, enabling multi-tenant environments by segregating traffic securely.
3. Which method is commonly used to achieve high availability in NVIDIA InfiniBand networks?A) Using a single switch with redundant power suppliesB) Deploying multiple redundant switches and links with failover capabilitiesC) Disabling adaptive routingD) Assigning static PKeysCorrect answer: BExplanation: High availability is typically achieved by deploying redundant switches and links that can automatically failover in case of hardware or link failure.
4. During initial provisioning, what role does the NVIDIA Unified Fabric Manager (uFM) play in high availability setup?A) It configures PKeysB) It monitors link status and bandwidth utilizationC) It assigns QoS prioritiesD) It disables unused portsCorrect answer: BExplanation: uFM provides centralized monitoring of the InfiniBand fabric, including link status and bandwidth, which is critical for maintaining high availability.
5. Which configuration is essential to ensure traffic can be rerouted automatically in case of a link failure?A) Static routingB) Adaptive routingC) Disabling PKeysD) Manual failoverCorrect answer: BExplanation: Adaptive routing allows the network to dynamically reroute traffic around failed or congested links, supporting high availability.
6. In the context of initial provisioning, what is the significance of verifying link status before configuring QoS?A) QoS settings depend on stable and active linksB) Link status is irrelevant to QoSC) QoS configuration automatically fixes link issuesD) QoS can only be applied after PKey assignmentCorrect answer: AExplanation: QoS policies require stable and active links to be effective; verifying link status first ensures the network is ready for further configuration.
7. Which of the following best describes a best practice for high availability setup in InfiniBand fabrics?A) Use a single path to reduce complexityB) Disable monitoring tools to improve performanceC) Implement redundant paths and continuous monitoringD) Assign all traffic to one partitionCorrect answer: CExplanation: Implementing redundant paths combined with continuous monitoring (e.g., via uFM) ensures quick detection and recovery from failures, enhancing availability.
