Which two practices help maintain reliability in a production multi-agent environment?

Maintaining reliability in any distributed system, including a multi-agent environment, relies on core Site Reliability Engineering (SRE) principles. Health checks and monitoring (A) are essential for observability, allowing operators to detect failures, performance degradation, and anomalies. Redundant service instances (B) are a fundamental practice for achieving high availability; if one agent instance fails, traffic can be routed to a healthy replica, preventing a service outage. Together, these practices ensure the system remains operational and resilient to failures.

C. A single point of failure is a design anti-pattern that decreases reliability by creating a component whose failure will take down the entire system.

D. Disabling alerting would prevent operators from being notified of issues, directly undermining the ability to maintain a reliable service.

E. Avoiding logs in production makes it nearly impossible to diagnose and troubleshoot problems, which is critical for restoring service and ensuring long-term reliability.
