What is the primary purpose of network monitoring in an AI environment?

To replace the need for security controls

To increase the bandwidth of the network

To observe AI workload performance and detect anomalies

To reduce the latency of AI inference

Which network design approach best supports the scalability of AI workloads as model sizes grow?

Keeping all AI traffic on a single VLAN

Relying on a single high-capacity core switch

Designing a fabric with modular, non-blocking architecture that can add capacity incrementally

Using a fixed, oversubscribed topology to limit cost

What is the primary purpose of a scale-out fabric in an LLM training cluster?

To interconnect a large number of GPU servers with high bandwidth and low latency

To provide internet connectivity for the training cluster

To simplify the management of storage systems

To replace the need for high-performance interconnects like InfiniBand

A network designer is supporting a pattern recognition application that analyzes video feeds in real time. Which network design principle is most important to meet the application's latency requirements?

Centralizing all processing in a single data center to simplify management

Placing processing resources close to the data source (edge processing)

Increasing the number of hops between source and processing

Using high-latency satellite links for data transport
