Which of the following communication and collaboration practices BEST contribute to the effectiveness of the SRE team?

The effectiveness of an SRE team, and the DevOps culture it embodies, is critically dependent on transparency and rapid feedback loops. The free flow of data—including metrics, logs, alerts, and postmortem reports—within the SRE team and between SRE and development teams is essential. This practice breaks down information silos, enables shared context, facilitates blameless problem-solving, and allows for data-driven decisions about reliability and engineering priorities. Limiting or siloing data creates friction and slows down the entire system.

A. Limiting data and requiring requests for it creates bottlenecks and information silos, which is directly contrary to effective SRE and DevOps principles.
C. Separating SRE data from others prevents developers and product managers from understanding the operational reality of their services, hindering collaboration and shared ownership.
D. Individual team members managing data discretely leads to a fragmented view of the system and prevents the team from collaborating effectively on systemic issues.
