CLF-C02 Question 14
Select 3A startup is planning to migrate its on-premises web application to the AWS Cloud. To ensure high availability, scalability, and cost-effectiveness, which design principles should they prioritize?
- A
Design for failure and implement redundancy
- B
Implement tightly coupled architecture for efficiency
- C
Use managed services to reduce operational complexity
- D
Provision resources for peak traffic at all times
- E
Automate to make architectural experimentation easier
Show answer and explanation
Correct answers: A, C, E
Explanation
The AWS Cloud design principles focus on enabling high availability, scalability, cost efficiency, and operational excellence. Designing for failure ensures resilience, while using managed services and automation reduces operational complexity and enables innovation. Avoiding tightly coupled architectures and over-provisioning resources helps maintain flexibility and cost-effectiveness.
- A. Correct.
Designing for failure and implementing redundancy ensures that the application remains highly available even if individual components fail. This is a key AWS Cloud design principle.
- B. Incorrect.
Tightly coupled architecture is not recommended in the AWS Cloud as it reduces scalability and resilience. Instead, loosely coupled architectures should be implemented.
- C. Correct.
Using managed services such as Amazon RDS or AWS Lambda offloads operational tasks like patching and scaling, enabling better focus on business functionality.
- D. Incorrect.
Provisioning resources for peak traffic at all times leads to unnecessary costs. Instead, leveraging auto-scaling ensures resources match demand dynamically.
- E. Correct.
Automation helps reduce manual intervention and supports rapid experimentation and iteration, which aligns with AWS design principles.
