Question #8 (Topic: Exam A)
What does workload distribution offer in an AI infrastructure with local and external resources?
A. isolation of analytic functions within remote processing clusters
B. distribution of computational tasks across multiple locations
C. restriction of automation to local storage and performance measures

Answer: C
Question #9 (Topic: Exam A)
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 switch configuration “hardware profile spectrum-x” in global configuration mode.
D. Include matching statements in your QoS policy so the switch knows which incoming packets to load balance.
Answer: B
Question #10 (Topic: Exam A)
Which network design approach should be used to build a high-performance, nonblocking AI/ML data center fabric that supports 64 fully equipped UCS C885A nodes and provides the lowest possible latency and lossless Ethernet?
A. leaf-spine
B. flat Layer 2
C. rail optimized
D. traditional three-tier
Answer: C
