Adaface Sample Microservices Questions

Which of the following are responsible for handling transactions spanning multiple services?

Consider a microservices architecture with three services: Service A, Service B, and Service C. Service A communicates with Service B and C using HTTP. To improve scalability and resilience, the following changes have been made:
            
            1. Introduced a load balancer for Service B and C
            2. Implemented a retry mechanism for Service A's communication with Service B and C, with exponential backoff strategy

Given the changes, which of the following statements are true? (Choose 2)
            
            A: The architecture now supports horizontal scaling for Service B and C
            B: The retry mechanism will ensure zero downtime for Service A
            C: The load balancer will ensure requests to Service B and C are evenly distributed
            D: The architecture will automatically recover from failure in Service B and C
            E: The retry mechanism with exponential backoff will prevent overwhelming Service B and C during temporary failures
