Cisco Implementing Cisco Data Center AI Infrastructure Sample Questions:
1. Refer to the exhibit. Users report delayed response times and network latency when running certain AI workloads on a specific Cisco UCS Intersight Managed Mode Domain. Based on the fault message and reported symptoms, which troubleshooting action must be taken first to address the network latency issues?
A) Check the physical cabling and SFP+ transceivers on port 11 of switch B for potential hardware failures or incorrect configurations.
B) Review the pause frame counters for signs of congestion on Fabric Interconnect B Port 11.
C) Examine the UCS fabric interconnect configuration for port-channel 11 on Fabric Interconnect B.
D) Review the AI workload configuration to optimize resource allocation (CPU, memory, GPU) for the affected applications.
2. Which IP-based storage transport supports flow control between directly connected devices?
A) NVMe/RoCE
B) NVMe/TCP
C) iSCSI
D) Fibre Channel
3. How does RAG enhance the capabilities of LLMs?
A) by providing access to proprietary data
B) by removing inherent biases from LLM outputs
C) by removing the data preparation and cleaning step
D) by retaining the LLM by altering its core parameters
4. A Cisco Nexus switch participates in an AI cluster using ECMP forwarding. Several flows between GPU servers consistently use the same uplink, creating congestion while other links remain underutilized. Which action improves traffic distribution?
A) Modify the hashing algorithm
B) Disable hashing
C) Increase MTU size
D) Enable port security
5.
