Which of the following is a new feature in R80.10 Gateway that was not available in R77.X and older?

The capability to create Sub Policies in R80.10 is a notable advancement that enhances the flexibility and organization of security policies compared to previous versions like R77.X. Sub Policies allow administrators to establish specific sets of rules that can be associated with particular rules, facilitating a more modular approach to security management. This feature is particularly beneficial in complex environments where managing large rule bases is necessary, as it enables more granular control and the ability to handle different types of traffic or security needs in a more structured manner.

In older versions, such as R77.X, policy management was more rigid, and the introduction of Sub Policies allows for better scalability and easier maintenance of security rules, accommodating the evolving needs of modern network environments.
