Page 90 Use SDN capabilities for multiple virtual networks and multiple cloud counts/segments to increase network isolation.

B. True To increase network isolation, you should indeed use Software-Defined Networking (SDN) capabilities for multiple networks and cloud accounts or segments. SDN allows you to create and manage virtual networks with specific segmentation and isolation, enhancing security and control by logically separating different parts of your infrastructure and preventing unauthorized access between them. This can be particularly useful in multi-tenant cloud environments where various customers' resources need to be isolated from each other.
