Question #11 (Topic: Exam A)
A global enterprise is deploying a new AI-driven analytics platform that requires high-performance GPU acceleration, large memory capacity, and robust virtualization support. The current compute environment must co-exist with the newly purposed GPU-enabled workload. This environment will continue to grow, so the customer wants to scale out the resources as needed. Which Cisco product meets the requirements?
A. UCS X-series
B. UCS M-series
C. Unified Edge
D. UCS C-series Standalone
Answer: A

policy managed through cloud-based interface
low latency between specific pairs of GPUs
at least 2 GPUs per server
all GPUs should be same model
Intel CPU
well suited for Inferencing
customer is power conscious

Question #13 (Topic: Exam A)
A company deploys a Cisco UCS environment to host AI inferencing workloads that demand low latency, high throughput, and efficient resource utilization. Which set of actions must be taken to deploy a high-performance fabric within the Cisco UCS infrastructure?
A. Deploy a Cisco MDS 9000 Series Switch for Fibre Channel connectivity to storage.
Use a Cisco Fabric Interconnect for management traffic only. B. Connect UCS servers to a Cisco Nexus 3000 Series Switch using 100 Gb Ethernet.
Configure a separate management network using a dedicated Cisco Catalyst switch. C. Use a single Cisco Fabric Interconnect in a standalone configuration.
Connect all UCS servers directly to it using 10 Gb Ethernet. D. Implement a dual-fabric design with two Cisco Fabric Interconnects, and use 100 Gb Ethernet for server-to-fabric connectivity.
Configuring port channels for uplink connections.

Question #14 (Topic: Exam A)
An organization deploys a new AI training fabric that uses RoCEv2 for GPU communication. The network architect designs the QoS configuration to ensure reliable RDMA transport and must meet these requirements:
Support 256 GPU servers with RDMA connectivity.
Prevent any packet loss that causes RDMA connection failures.
Maintain consistent low-latency communication with a target of less than 10 microseconds.
Use industry-standard protocols and configurations.
Which configuration ensures that RoCEv2 operates as a lossless transport?

Which configuration ensures that RoCEv2 operates as a lossless transport?
A. Implement traffic shaping to smooth RDMA traffic bursts and prevent congestion.
B. Enable Priority Flow Control on the traffic class carrying RoCEv2 packets.
C. Set the RDMA traffic to use the highest DSCP value to ensure priority forwarding.
D. Configure weighted fair queuing to prioritize RDMA traffic over other traffic classes.
Answer: B
Question #15 (Topic: Exam A)
An Intersight administrator plans to deploy new server solutions to several small branch offices across the country. Each location needs at least one chassis. The servers must have redundant CPUs, memory, and 200 Gbps of unified fabric connectivity per compute node. Which hybrid AI compute solution meets the requirements?
A. Cisco UCS S3260
B. Cisco UCS X-Direct
C. Cisco UCSXE Unified Edge
D. Cisco UCS C885A M8
