Which are two advantages of a "one switch at a time" approach to integrating SD-Access into an existing brown field environment? (Choose two.)

This approach provides flexibility, allowing organizations to integrate SD-Access into different parts of their network infrastructure, from large campuses to smaller remote sites, without requiring a complete overhaul.

Rolling back a "one switch at a time" integration can be complex as it involves directly modifying existing production infrastructure and disentangling new configurations.

Directly modifying existing production infrastructure, even gradually, can introduce operational risks, making it potentially riskier than a parallel fabric deployment.

This integration method focuses on migration and adaptation rather than enabling entirely new network design paradigms, which are inherent to SD-Access itself rather than this specific adoption strategy.

By integrating devices one by one, organizations can continue to utilize their functional, recently purchased network equipment, extending its lifecycle while strategically upgrading older, legacy hardware to support SD-Access capabilities.

Testing with a "one switch at a time" approach often occurs directly within the live production environment, which can complicate isolated pre-cutover testing compared to a parallel deployment.
