NCP-AIN mock exam

Question 1, NVIDIA Spectrum NetworkingRoCE traffic suffers under congestion on an Ethernet fabric. Which features are key to making it perform?

• ADHCP and DNS tuning on the leaf switches
• BNAT and PAT at the fabric edge
• CPFC and ECN for lossless, congestion-aware delivery
• DSTP and LLDP for a loop-free, discovered topology

Question 2, NVIDIA Spectrum NetworkingWhat does Spectrum-X add for AI workloads on Ethernet?

• AAdaptive routing and congestion control tuned for AI traffic
• BLayer 7 load balancing for inference APIs
• CStatic routing with a fixed path for each flow
• DTraditional ECMP hashing with larger buffers

Question 3, NVIDIA Spectrum NetworkingWhich CLI do you use to configure Cumulus Linux in current versions?

• ANVUE
• BPowerShell Direct
• CNetBIOS
• DIIS Manager

Question 4, NVIDIA InfiniBand NetworkingAn InfiniBand fabric has no active subnet manager. What is the effect?

• AOnly monitoring stops, and links keep carrying traffic as normal
• BLinks work as normal until the next cable change
• CPorts will not reach the active state, so traffic does not flow
• DOnly latency increases, because routes are not optimized

Question 5, NVIDIA InfiniBand NetworkingWhich NVIDIA product provides central monitoring and management of an InfiniBand fabric?

• ANVIDIA Air simulation
• BNVIDIA NetQ
• CUnified Fabric Manager (UFM)
• DNVIDIA Spectrum SDK

Question 6, Troubleshooting ToolsYou suspect bad links across an InfiniBand fabric. Which tool scans it for errors?

• Aibdiagnet
• Bchkdsk
• Ctracert only
• Dping only

Question 7, Automation and ConfigurationYou must apply the same switch configuration to 200 switches without drift. What is the right approach?

• AConfigure each one by hand over the console using a checklist
• BCopy and paste from a text file kept on a jump host
• CDeclarative automation such as Ansible, kept in version control
• DChange one switch and let LLDP spread the settings

Question 8, Kubernetes IntegrationKubernetes pods need RDMA and SR-IOV networking on NVIDIA NICs. Which component helps deploy this?

• AAn ingress certificate
• BNVIDIA Network Operator
• CNVIDIA Canvas
• DA sidecar log shipper
