Google’s SRE model includes the role of Launch Coordination Engineer (LCE), described in the SRE Book as: “an engineer who serves as the central liaison between product teams, SRE, and other stakeholders to ensure safe and reliable launches.” (SRE Book – Chapter: Production Environment & Launch Coordination). Their responsibilities include assessing launch readiness, ensuring SLOs are defined, facilitating cross-team communication, and managing risk associated with new service rollouts.

Option C precisely reflects this role: acting as a consultant and liaison across all parties involved in a launch.

Option A focuses on server engineering, which is not the focus of LCE.

Option B describes application-level performance work, unrelated to cross-team launch facilitation.

Option D describes operational tuning, not coordination.

Thus, C is the correct answer, capturing the SRE-defined launch coordination function.

Availability is the most widely tracked and commonly understood SLO across nearly all digital services. It measures whether users are able to successfully access and use the system. Because unavailability directly impacts user experience, revenue, trust, and reliability, it is the primary SLO used across industries.

The Site Reliability Engineering Book, Chapter “Service Level Objectives,” states:

“Availability is one of the most common and important SLOs since it reflects the basic ability of the service to function for users.”

The SRE Workbook also notes:

“Availability targets (e.g., 99.9%, 99.99%) are the most widely used form of SLOs and form the foundation of error budget policies.”

While performance SLOs are also common, availability SLOs are almost universal and foundational.

Thus, D. Availability is the correct answer.

Containers provide a major advantage that aligns with SRE: portability and environment consistency. The SRE Workbook describes containers as: “lightweight, portable units that encapsulate applications and dependencies, ensuring consistent behavior across environments.” This independence from the host OS environment enables predictable deployments and simplifies automation, scaling, and orchestration—especially when used with Kubernetes.

Option A captures this exact benefit: portability and independence from the host OS.

Option B is incorrect—containers do not reduce the number of developers required.

Option C incorrectly claims that efficiency comes from virtual machines; containers are typically more efficient because they avoid VM overhead, not leverage it.

Option D is incorrect—containers do not “inherit” security automatically; in fact, they require additional security controls.

Thus, A is the correct answer.
