Question 1
A rapidly growing e-commerce platform is transitioning from a monolithic architecture to microservices. They need to ensure data consistency for transactions that span multiple services, such as processing an order which involves updating inventory, charging the customer, and arranging for shipping. If any of these steps fail, the entire transaction must be rolled back. Which architectural pattern is most suitable for managing this multi-service transaction?
Correct Answer:
Saga Pattern
Question 2
An enterprise is planning to modernize a large, business-critical legacy monolithic application. A 'big bang' rewrite is considered too risky due to the potential for service disruption. The goal is to incrementally replace parts of the legacy system with new microservices over time, while the entire application remains operational for users. Which design pattern provides a structured approach for this gradual migration?
Correct Answer:
Strangler Fig Pattern
Question 3
A financial services application requires a complete and immutable audit trail of all transactions. For compliance and analytical purposes, the business needs the ability to reconstruct the state of any account at any point in history. Simply storing the current state of the data is insufficient. Which pattern best addresses this requirement?
Correct Answer:
Event Sourcing
Question 4
A complex system has significantly different requirements for reading and writing data. The read operations are frequent, high-volume, and need to be highly optimized for performance using denormalized data structures. The write operations are less frequent but involve complex business logic and validation on a normalized model. Which pattern would be most effective for architecting this system?
Correct Answer:
Command Query Responsibility Segregation (CQRS)
Question 5
Which of the following is a significant drawback when choosing a microservices architecture over a monolithic architecture for a small, startup team with a tight deadline for their initial product launch?
Correct Answer:
Higher initial operational complexity and overhead.
