NVIDIA's What Just Happened (WJH) is a feature that provides real-time visibility into network problems by analyzing all packets passing through the switch and alerting on performance issues caused by packet drops, congestion, high latency, or misconfigurations. WJH retains the last packets that were dropped from the switch with complete packet headers and the actual drop reason. This enhances the ability to debug network problems, identify affected flows, and decrease time-to-repair.
Question 52
You are using NVIDIA Air to simulate a Spectrum-X network for AI workloads. You want to ensure that your network configurations are optimal before deployment. Which NVIDIA tool can be integrated with Air to validate network configurations in the digital twin environment?
Correct Answer: C
NVIDIA NetQ is a highly scalable network operations toolset that provides visibility, troubleshooting, and validation of networks in real-time. It delivers actionable insights and operational intelligence about the health of data center networks-from the container or host all the way to the switch and port-enabling a NetDevOps approach. NetQ can be used as the functional test platform for the network CI/CD in conjunction with NVIDIA Air. Customers benefit from testing the new configuration with NetQ in the NVIDIA Air environment ("digital twin") and fix errors before deploying to their production.
Question 53
You are automating the deployment of a Spectrum-X network using Ansible. You need to ensure that the playbooks can handle different switch models and configurations efficiently. Which feature of the NVIDIA NVUE Collection helps simplify the automation by providing pre-built roles for common network configurations?
Correct Answer: C
The NVIDIA NVUE Collection for Ansible includes pre-built roles designed to streamline automation tasks across various switch models and configurations. These roles encapsulate common network configurations, allowing for efficient and consistent deployment. By utilizing these roles, network administrators can: * Apply standardized configurations across different devices. * Reduce the complexity of playbooks by reusing modular components. * Ensure consistency and compliance with organizational policies. This approach aligns with Ansible best practices, promoting maintainability and scalability in network automation. Reference: NVIDIA NVUE Collection Documentation - Ansible Roles
Question 54
You are configuring the Unified Fabric Manager (UFM) for an InfiniBand fabric in a multi-tenant environment. You need to implement a solution that can detect potential security threats. Which UFM feature uses analytics to detect security threats and predict network failures in InfiniBand data centers?
