The Cisco 300-640 exam, Implementing Cisco Data Center AI Infrastructure, is part of the Cisco Certified Network Professional and Cisco Certified Network Professional Data Center certification path. It is designed for networking and data center professionals who want to validate their knowledge of AI-ready infrastructure in Cisco environments. This exam matters because it focuses on the practical skills needed to support modern AI workloads in data center operations. Passing it demonstrates that you can work confidently with AI infrastructure concepts, deployment, and troubleshooting.

# Exam Topics Sub-Topics Approximate Weightage (%)
1 AI infrastructure Components and Architecture Data center AI building blocks, compute and network roles, storage considerations, reference architecture concepts 30%
2 AI infrastructure Deployment and Data Management Infrastructure deployment flow, configuration basics, data handling, data movement and management practices 25%
3 AI infrastructure Operations and Troubleshooting Monitoring, fault isolation, operational checks, troubleshooting common infrastructure issues 25%
4 AI Fundamentals and Applications Core AI concepts, common AI use cases, workload awareness, application alignment in data center environments 20%

This exam tests both conceptual understanding and practical implementation knowledge. Candidates should be able to recognize AI infrastructure components, understand deployment and data management requirements, and troubleshoot operational issues in a Cisco data center setting. It also checks whether you can connect AI fundamentals to real-world applications and infrastructure decisions. In short, the exam expects more than memorization - it measures applied knowledge and readiness for day-to-day technical work.

Actual Cisco 300-640 Exam Questions

Question 1

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?

Correct answer: B

Question 2

A medical company has existing third-party AI servers and NVMe storage, but they want to purchase Cisco network switches with a cloud managed feature for simplicity.

Which solution best meets the requirements?

Correct answer: B

Question 3

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?

Correct answer: B

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?

Correct answer: B

In a UCS 885a server with six 3000W power supplies configured in redundant mode (3 per grid), when one power grid is shut down for maintenance, the server will shut down to protect remaining components. In redundant mode, the system requires simultaneous power from both grids for proper operation. Loss of one grid means the remaining supplies cannot maintain full redundancy, so the server initiates a controlled shutdown to prevent damage from inadequate power distribution and to protect data integrity.

Question 5

A network engineer analyzes RoCEv2 traffic flows in an AI training cluster and notices that all RoCEv2 packets have the Don't Fragment bit set in the IP header.

Why must RoCEv2 set the DF bit in all packets?

Correct answer: D
