Dive into our fully updated and stable 300-640 practice test platform, featuring all the latest CCNP Data Center exam questions added this week. Our preparation tool is more than just a Cisco study aid; it's a strategic advantage.
Our free CCNP Data Center practice questions crafted to reflect the domains and difficulty of the actual exam. The detailed rationales explain the 'why' behind each answer, reinforcing key concepts about 300-640. Use this test to pinpoint which areas you need to focus your study on.
A network team is configuring quality of service (QoS) for RoCEv2 traffic on a VXLAN fabric. The team must ensure that congestion notification packets (CNP) generated by storage targets are never dropped in the network, as these packets are critical for congestion control feedback.
How must CNP packets be handled in the QoS configuration to ensure reliable delivery?
To support growing AI workload requirements, a regional medical practice is adding new X9516 X-Fabric module, UCS PCI Mezz cards, and UCS X580p PCIe nodes to their existing X-Series chassis.
Which two administrative actions must be taken before the X-Fabric module is added to the chassis? (Choose two.)
Refer to the exhibit.
Users report delayed response times and network latency when running certain AI workloads on a specific Cisco UCS Intersight Managed Mode Domain.
Based on the fault message and reported symptoms, which troubleshooting action must be taken first to address the network latency issues?
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?
A customer is deploying a new AI fabric with all new NVIDIA GPUs and must verify the performance between the nodes in the network.
Which tool must be used to validate the customer benchmarks?
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?
What is a primary behavior that occurs during the model training stage of the AI lifecycle?
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?
What does workload distribution offer in an AI infrastructure with local and external resources?
A data center administrator for a medium-sized manufacturing facility uses Intersight to perform unattended operating system installation on already discovered X-Series servers with server profiles assigned.
Which set of prerequisites must be met for installing an operating system on a server in Cisco Mode?
