Which of the following BEST describes an advantage of a container-based structure?
Correct Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract: 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.

Question 2
Which of the following BEST describes the capabilities and scope of DevOps continuous monitoring?
Correct Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract: SRE and DevOps share a common view of continuous monitoring—a holistic approach that enables rapid detection, diagnosis, and response across all parts of the system. The SRE Book states: “Monitoring must enable fast detection of anomalies, quick diagnosis, and effective incident response.” Continuous monitoring includes application metrics, infrastructure signals, logs, traces, service health, and user-experience telemetry. Option B captures this accurately: a combination of tools and processes enabling rapid incident detection and response, especially for cloud services. Option A is partially correct but too narrow (only end-user transactions). Option C is generic and does not emphasize continuous or rapid detection. Option D describes infrastructure monitoring only—not full DevOps/SRE continuous monitoring. Thus, B is the correct answer.

Question 3
Which of the following BEST describe the characteristics of a product team? They are small and collaborative They have cross-functional skillsets They do not share responsibilities They discourage any feedback
Correct Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract: Modern SRE-aligned organizations use small, cross-functional product teams capable of owning design, development, testing, and operational reliability. The SRE Book emphasizes: “Effective service ownership arises from small, autonomous teams with diverse skillsets and strong collaboration habits.” These teams share responsibility, encourage feedback, and maintain open communication to meet reliability goals. Option A correctly identifies the two positive characteristics: Small and collaborative Cross-functional skillsets Options 3 and 4 represent dysfunctional behaviors—SRE literature explicitly discourages responsibility silos and discouraging feedback, as these reduce reliability and slow incident learning. Thus, A is the correct answer. [References:, Site Reliability Engineering, Chapter: “Organization and Culture.”, The Site Reliability Workbook, discussions on product-oriented team structures., ]
