Demo Questions

Question 1
Which function is provided through natural language processing?
  1. compression of large configuration files for storage efficiency
  2. automated conversion of spoken or written content into structured data
  3. annotation of data transmission protocols for device authorization
  4. filtration of duplicate entries from transaction records
Correct answer: B
Question 2
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?
  1. Cisco UCS S3260
  2. Cisco UCS X-Direct
  3. Cisco UCSXE Unified Edge
  4. Cisco UCS C885A M8
Correct answer: B
Question 3

Which solution best meets the requirements?
  1. Bring Your Own AI (BYO AI) HyperFabric with Cisco 6000 Series Switches and Essentials license
  2. Bring Your Own AI (BYO AI) HyperFabric with Cisco 6000 Series Switches and Premier license
  3. Nexus Dashboard with Nexus 9000 Series Switches and Cloud license
  4. HyperFabric AI with Cisco 6000 Series Switches and Premier license
Correct answer: B
Question 4
What describes inference traffic patterns in AI deployments?
  1. optimizes data storage solutions for data lakes
  2. simplifies complex neural network architectures
  3. provides real-time decision making
  4. eliminates the need for data preparation
Correct answer: C
Question 5
What is a primary behavior that occurs during the model training stage of the AI lifecycle?
  1. embedding the model into systems with APIs
  2. establishing success criteria
  3. adjusting internal weights and biases
  4. detecting model drift
Correct answer: C
Question 6
A company is building a network fabric for an AI training cluster that will train large language models. The cluster includes 256 GPUs distributed across 32 servers. Security requirements mandate isolation between different training projects and allowing shared access to a central storage system.
Which approach provides the required security isolation and maintains optimal performance for GPU-to-GPU communication?
  1. Deploy separate physical networks for each project with dedicated switches and cross-connects to shared storage.
  2. Use VXLAN with separate VNIs per project and Group Policy Option to control granular access to shared storage.
  3. Implement port-based VLANs for each project with router ACLs controlling storage access at the distribution layer.
  4. Configure QoS-based traffic steering with separate DSCP markings per project and policy-based routing to shared storage.
Correct answer: B
Question 7
A medium-sized breadmaking operation must deploy a fleet of GPU servers that meet these requirements for their flagship application: 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
Which server meets the requirements?
  1. C245 M8
  2. X210C M8 with x580 PCIe node
  3. C845A M8
  4. C885A M8
Correct answer: B
Question 8
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?
  1. Deploy a Cisco MDS 9000 Series Switch for Fibre Channel connectivity to storage. 
    Use a Cisco Fabric Interconnect for management traffic only.
  2. 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.
  3. Use a single Cisco Fabric Interconnect in a standalone configuration. 
    Connect all UCS servers directly to it using 10 Gb Ethernet.
  4. 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.
Correct answer: D
Question 9
What is the process involved in workload scheduling for AI environments?
  1. assignment of tasks to compute elements for optimized performance
  2. optimization of licensing structures for compliance
  3. aggregation of device statistics for reporting
  4. generation of backup images for restoration operations
Correct answer: A
Question 10
What does workload distribution offer in an AI infrastructure with local and external resources?
  1. isolation of analytic functions within remote processing clusters
  2. distribution of computational tasks across multiple locations
  3. restriction of automation to local storage and performance measures
  4. enforcement of fixed security policies on distribution endpoints
Correct answer: C
Question 11
A financial company plans to deploy an AI training and inference infrastructure to support its customers. The team must use a solution that provides 96 GPUs, aligns with NVIDIA-compliant reference architectures, and enables cloud-based management of the entire on-premises network environment.
