Answer: Introduce a green-blue deployment model, Fragment the monolithic platform into microservices
The correct answers are A and C. Introducing a green-blue deployment model (Option A) helps in reducing unplanned rollbacks as it ensures that deployment can be tested in a production-like environment without affecting the live environment. If errors occur in the new deployment, traffic can be quickly redirected to the stable setup, minimizing downtime and rollback needs. Fragmenting the monolithic platform into microservices (Option C) enhances the system's modularity and fault isolation, making it easier to identify and fix errors without affecting the entire platform. Options B, D, and E do not directly address the need to reduce rollback rates in the context mentioned.
