Implementing Cisco Data Center AI Infrastructure (300-640) Free Practice Test

Question 1

An engineer must optimize the performance of an AI inference workload running on a Cisco UCS C-Series rack server. The workload experiences intermittent latency spikes, and Intersight system logs show frequent thermal event entries. Which troubleshooting action must be taken first to address the performance issues on the Cisco UCS server?

A. Examine the storage configuration, including the RAID configuration and disk health, to ensure that the storage subsystem is not causing latency issues.

B. Check the power supply status and power consumption of the UCS server using UCS Manager to ensure that the server has sufficient power.

C. Inspect the physical environment of the server, including ambient temperature and airflow, and replace any failed fans.

D. Review the resource utilization of the AI workload (CPU, memory, and GPU) to identify potential bottlenecks and optimize resource allocation.

Question 5

An engineer deploys an AI fabric on Cisco Nexus 9000 Series Switches connected to Cisco UCS nodes with NVIDIA GPUs. The requirements call for optimal network performance for training workloads. Adaptive routing is enabled on the NICs, and per-packet load balancing is enabled on the switches. Which other configuration must be implemented for this integration to be fully operational?

A. Add the "adaptive-routing" keyword under the switch load balancing configuration.

B. Set the cisco_dlb=1 option in the NIC configuration so the NIC knows it can use adaptive routing.

C. Include matching statements in your QoS policy so the switch knows which incoming packets to load balance.

D. Include switch configuration "hardware profile spectrum-x" in global configuration mode.

Question 6

A large-scale retail store manages many compute resources spread across branch offices, which enables AI workloads to be processed on-premises. Each workload and site location requires specific OS installation and configuration. To simplify management, configuration, and deployment of the workloads, a Cisco Intersight feature must be used that enables workload deployment at scale. Which feature must be used to accomplish this functionality?

A. domain management

B. server management

C. fleet management

D. chassis management

Question 7

When considering a rail-only network design, when would adding spine switches make sense?

A. when providing greater overall total bandwidth within a single scalable unit

B. when increasing the overall available buffers that spines provide

C. when scaling out to support traffic between multiple scalable units

D. when needing a greater path redundancy within a single scalable unit
