Cisco Implementing Cisco Data Center AI Infrastructure 認定 300-640 試験問題 (Q56-Q61):

質問 # 56
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. Deploy separate physical networks for each project with dedicated switches and cross-connects to shared storage.
B. Configure QoS-based traffic steering with separate DSCP markings per project and policy-based routing to shared storage.
C. Implement port-based VLANs for each project with router ACLs controlling storage access at the distribution layer.
D. Use VXLAN with separate VNIs per project and Group Policy Option to control granular access to shared storage.

正解：D

解説：
VXLAN provides scalable network segmentation by assigning separate VNIs to different training projects, preserving isolation without building separate physical fabrics. Group Policy Option adds policy-based control within the VXLAN overlay, allowing controlled shared access to central storage while maintaining high-performance GPU-to-GPU communication across the AI training fabric.

質問 # 57
A national law firm is deploying a RAG solution for their legal research team to more efficiently use their 50 TB of confidential data and documents when preparing new contracts and briefs.
They decided on a UCS X-Series chassis equipped with four GPUs and six X210c servers. Which storage solution fits this deployment?

A. tape storage
B. local storage in a JBOD configuration
C. IP-based storage array
D. local storage in a RAID 5 configuration

正解：C

解説：
A RAG deployment with 50 TB of confidential documents requires scalable shared storage that can be accessed by multiple UCS X210c servers. An IP-based storage array provides centralized capacity, shared access, and operational simplicity for storing and retrieving large datasets used by the RAG pipeline.

質問 # 58
When considering a rail-only network design, when would adding spine switches make sense?

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 increasing the overall available buffers that spines provide
D. when scaling out to support traffic between multiple scalable units

正解：D

解説：
In a rail-only design, each scalable unit provides optimized east-west GPU communication within that unit. Spine switches are added when the design must scale beyond a single scalable unit and support traffic between multiple scalable units while preserving predictable performance for larger AI training environments.

質問 # 59
What describes inference traffic patterns in AI deployments?

A. eliminates the need for data preparation
B. simplifies complex neural network architectures
C. optimizes data storage solutions for data lakes
D. provides real-time decision making

正解：D

解説：
Inference traffic is associated with using a trained model to generate predictions or responses from new input data. In AI deployments, this commonly supports real-time or near-real-time decision making, such as classification, recommendations, detection, or automated responses.

質問 # 60
An engineer notices excessive broadcast traffic inside a legacy AI server VLAN. Which technology should be implemented to reduce flooding and improve scalability?

A. PAT
B. VXLAN EVPN
C. RIP
D. GRE tunneling

正解：B

解説：
VXLAN EVPN reduces unknown unicast and broadcast flooding by using control-plane learning with BGP EVPN. This improves scalability in modern AI data centers. RIP is outdated for large- scale fabrics, while PAT and GRE tunneling do not address broadcast domain limitations.
