Question 1
Which of the following BEST describes an advantage of a container-based structure?
- AOption A:
The portability created by containers enables software to run independently of the host operating system
- BOption B:
The lightweight nature of containers requires fewer developers to actually create the software code
- COption C:
Software runs much more efficiently in containers because of the ability to run on virtual machines
- DOption D:
The security of applications in containers is simplified because they share the security of the host system
Show answer and explanation
Correct answer: A
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?
- AOption A:
The application of widespread system event monitoring by automating the end-user transactions
- BOption B:
The combination of tools and the process for rapid incident detection and response of cloud services
- COption C:
The use of multiple monitoring tools and an event management process for all applications
- DOption D:
The deployment of a set of integrated monitoring tools and event thresholds for infrastructure
Show answer and explanation
Correct answer: B
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.
