Free Implementing Cisco Data Center AI Infrastructure (DCAI) Practice Questions

Question # 1

An engineer made changes to the corporate DNS, which caused a Cisco UCS X-Series domain to lose connectivity to Intersight. To restore connectivity, the management interface DNS and NTP settings must be updated using the device console UI.

Which configuration change must be made in Intersight to allow the updated DNS configuration to persist?

Options:

A.  

Edit the IMC access policy associated to the fabric interconnects.

B.  

Create a device connector policy and apply it to the blade chassis.

C.  

Create a network connectivity policy and apply it to the blade chassis.

D.  

Edit the domain profile deployed to the fabric interconnect.

Question # 2

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?

Options:

A.  

domain management

B.  

server management

C.  

fleet management

D.  

chassis management

Question # 3

What is a primary behavior that occurs during the model training stage of the AI lifecycle?

Options:

A.  

embedding the model into systems with APIs

B.  

establishing success criteria

C.  

adjusting internal weights and biases

D.  

detecting model drift

Question # 4

A customer deploys a UCS 885a server in a data center with two power grids. Three of the 3000W power supplies in the server connect to each grid. Due to an external event, one of the grids will be shut down for maintenance.

How does the server respond to this event?

Options:

A.  

The server immediately shuts down and stops all operations.

B.  

The server operates with reduced performance and caps power to GPUs at 60%.

C.  

The server continues to operate at full performance using redundant power supplies, but the PSU status LED glows solid amber.

D.  

The server initiates a graceful shut down of the operating system.

Question # 6

An engineer is deploying a Cisco AI POD environment to support large-scale AI workloads. The solution must provide a software-defined storage platform with a Disaggregated Shared-Everything architecture, allow compute nodes to run on Cisco UCS C225 M8 servers managed through Cisco Intersight, and deliver exabyte-scale, all-flash performance with integrated high-speed RDMA and GPU Direct Storage capabilities.

Which solution meets the requirements?

Options:

A.  

NetApp All-Flash FAS (AFF)

B.  

Pure Storage FlashBlade

C.  

Local NVMe SSDs within each GPU server

D.  

VAST Data Universal Storage

Question # 7

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

Options:

A.  

when providing greater overall total bandwidth within a single scalable unit

B.  

when needing a greater path redundancy within a single scalable unit

C.  

when scaling out to support traffic between multiple scalable units

D.  

when increasing the overall available buffers that spines provide

Discussion 0
Question # 8

What is a function of NVLink technology within a high-performance AI server or cluster?

Options:

A.  

to enable remote access and virtualization of GPU resources for distributed AI development teams

B.  

to manage power distribution and thermal regulation across all installed GPU units

C.  

to establish a secure, encrypted channel for data transfer between the AI server and external storage

D.  

to provide a high-speed, low-latency direct interconnect for GPU-to-GPU communication

Discussion 0
Question # 9

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?

Options:

A.  

leaf-spine

B.  

flat Layer 2

C.  

rail optimized

D.  

traditional three-tier

Discussion 0
Question # 10

Which result is provided through image recognition using AI?

Options:
