Question

What are the minimum number of subnets required for configuring a virtual private cloud in a Cisco Catalyst SD-WAN controller cloud deployment?

Options

Explanation

A minimum of four subnets is typically required for configuring a virtual private cloud in a Cisco Catalyst SD-WAN controller cloud deployment to ensure proper segmentation and high availability.

Common mistakes.

A. One subnet is insufficient for the necessary segmentation of management, public, and private traffic components in a secure and scalable controller deployment.
B. Two subnets would not provide adequate segmentation for management, public, private, and internal controller communication, especially for high availability.
C. Three subnets might cover basic public/private/management, but typically falls short for the full functional and resilient architecture required for a controller cloud deployment, which often involves an additional private subnet for internal services or redundancy.
