In a hybrid network environment, integration with public cloud APIs is a critical requirement for a network assurance platform. This capability enables the platform to interact with cloud-native services, collect telemetry, and provide end-to-end visibility across on-premises infrastructure, public cloud resources, and SD-WAN components. While other options may contribute to different aspects of network assurance, they do not specifically address the integration and visibility challenges posed by hybrid architectures.

A. Incorrect.
While support for multi-vendor environments is important, it does not specifically address the need for integrating and gaining visibility into public cloud resources.
B. Incorrect.
Deep packet inspection (DPI) is useful for analyzing traffic patterns and anomalies, but it is not directly relevant to ensuring visibility and integration across hybrid networks.
C. Correct.
Integration with public cloud APIs is essential for hybrid networks because it allows the network assurance platform to gather telemetry, configuration, and performance data from public cloud resources, ensuring seamless visibility and management.
D. Incorrect.
SNMP-based monitoring is a traditional approach, but it has limitations when dealing with modern hybrid network architectures, especially those involving SD-WAN and cloud resources.

300-445 Question 4

Single answer
