Reliability
- B
Performance Efficiency
- C
Operational Excellence
- D
Cost Optimization
- E
Security
- F
Sustainability
Show answer and explanation
Correct answers: A, B, D
Explanation
To meet the requirements of high availability, low latency for global users, and cost optimization, the pillars of Reliability, Performance Efficiency, and Cost Optimization are the most relevant. Reliability ensures fault tolerance and availability, Performance Efficiency ensures the system can handle global traffic with low latency, and Cost Optimization helps manage expenses effectively. While other pillars are important, they do not directly address the core requirements of this scenario.
- A. Correct.
Reliability focuses on ensuring that a system can recover from failures, scale based on demand, and meet availability requirements, making it crucial for high availability.
- B. Correct.
Performance Efficiency involves using computing resources efficiently and selecting the right services to maintain low latency, which is important for global users.
- C. Incorrect.
Operational Excellence centers on running and monitoring systems to deliver business value and improve processes. While important, it is not the primary focus in this scenario.
- D. Correct.
Cost Optimization is critical for controlling and minimizing costs, which aligns with the need to optimize costs in the given scenario.
- E. Incorrect.
Security emphasizes protecting data and workloads. While always important, it is not directly tied to the requirements of high availability, low latency, and cost optimization in this case.
- F. Incorrect.
Sustainability focuses on reducing environmental impact by optimizing resources. While relevant in broader use cases, it is not directly related to the scenario's requirements.
