Q1:
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: Use VXLAN with separate VNIs per project and Group Policy Option to control granular access to shared storage.

C: Implement port-based VLANs for each project with router ACLs controlling storage access at the distribution layer.

D: Configure QoS-based traffic steering with separate DSCP markings per project and policy-based routing to shared storage.

Answer

Correct Answer: B

Q2:
What does workload distribution offer in an AI infrastructure with local and external resources?

A: isolation of analytic functions within remote processing clusters

B: distribution of computational tasks across multiple locations

C: restriction of automation to local storage and performance measures

D: enforcement of fixed security policies on distribution endpoints

Answer

Correct Answer: C

C: UCS Domain profiles

D: UCS Server profiles

Answer

Correct Answer: C

Q5:
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 scaling out to support traffic between multiple scalable units

D: when increasing the overall available buffers that spines provide

Answer

Correct Answer: C
