Question 1. What is the core principle of composable architecture that emphasizes dividing systems into independent, reusable modules? A) Monolithicity B) Modularity C) Centralization D) Monorepo Answer: B Explanation: Modularity is the core principle of composable architecture, focusing on dividing systems into independent, reusable components to enhance flexibility, scalability, and maintainability.
Question 2. How does composable architecture fundamentally differ from traditional monolithic architecture? A) It combines all functionalities into a single codebase. B) It emphasizes loosely coupled, independent components. C) It requires complete redeployment for changes. D) It relies solely on hardware upgrades. Answer: B Explanation: Composable architecture emphasizes loosely coupled, independent components that can be assembled or modified without affecting the entire system, unlike monolithic architecture which integrates all functionalities tightly into one system.
Question 4. Which of the following is a key benefit of composable architecture? A) Reduced flexibility B) Increased vendor lock-in C) Enhanced reusability of components D) Inability to scale Answer: C Explanation: Reusability of components is a key benefit of composable architecture, allowing organizations to reuse modules across different systems, reducing duplication and development time.
Question 5. Which principle of MACH architecture specifically emphasizes the use of APIs as primary integration points? A) Microservices B) API-first C) Cloud-Native D) Headless Answer: B Explanation: API-first emphasizes designing robust, secure, and well- documented APIs as the primary means of integrating and connecting components in a composable system.
Question 7. Which challenge is commonly associated with implementing microservices? A) Difficulties in scaling individual services B) Managing distributed data consistency C) Single point of failure in monoliths D) Limited technology choices Answer: B Explanation: Managing distributed data consistency is a common challenge in microservices architectures, especially in ensuring eventual consistency across multiple services.
Question 8. What does cloud-native architecture leverage to enhance scalability and resilience? A) On-premises hardware only B) Cloud infrastructure, containerization, and orchestration tools like Kubernetes C) Standalone virtual machines without orchestration D) Manual deployment processes Answer: B Explanation: Cloud-native architecture leverages cloud infrastructure, containerization (like Docker), and orchestration platforms (like Kubernetes) to achieve scalability, resilience, and flexibility.
A) User authentication system B) Inventory management module C) Payment processing service D) All of the above Answer: D Explanation: All options are examples of PBCs, which are autonomous, reusable, and business-focused modules like inventory, payment, or authentication systems. Question 11. What characteristic is essential for a well-defined PBC? A) Dependency on multiple systems B) Reusability across different processes
C) Deployment only in specific environments D) Limited business value Answer: B Explanation: Reusability across multiple processes or systems is essential for a PBC, enabling flexibility and efficiency in a composable enterprise. Question 12. Which architectural pattern is ideal for implementing event- driven communication in a composable system? A) Monolithic architecture B) Event-driven architecture C) Layered architecture D) Client-server architecture
Answer: B Explanation: Event-driven architecture enhances scalability and responsiveness by enabling asynchronous communication and decoupling components. Question 14. Which strategy minimizes dependencies between components to promote loose coupling? A) Tight integration with shared databases B) Implementing API gateways and service meshes C) Direct database access from all components D) Monolithic deployment Answer: B
Explanation: API gateways and service meshes help decouple components, manage dependencies, and promote loose coupling by controlling communication flows. Question 15. In domain-driven design, what defines a 'bounded context'? A) A large, unified domain with minimal boundaries B) A specific area of the domain with its own models and rules C) An isolated database without integration points D) A physical boundary within data centers Answer: B
Explanation: Total cost of ownership and vendor support are critical considerations when evaluating COTS PBCs to ensure they meet business needs and integrate effectively. Question 17. Which security aspect is critical when designing APIs for composable systems? A) Open access without authentication B) Strong authentication and authorization mechanisms C) No encryption of data in transit D) Avoiding logging for security reasons Answer: B
Explanation: Strong authentication and authorization are essential to secure APIs, preventing unauthorized access and ensuring data privacy. Question 18. How does identity and access management (IAM) support security in a distributed composable environment? A) By centralizing user credentials and access policies B) By removing access controls entirely C) By relying solely on network firewalls D) By encrypting only data at rest Answer: A
Explanation: Agile and DevOps practices enable continuous, rapid deployment and iteration, essential for maintaining flexibility in composable architectures. Question 20. What is the primary difference between orchestration and choreography in system integration? A) Orchestration is decentralized, choreography is centralized B) Orchestration involves a central controller, choreography relies on event- based communication without a central coordinator C) Choreography requires a master service, orchestration does not D) They are interchangeable terms with no difference Answer: B
Explanation: Orchestration involves a central controller managing workflows, while choreography relies on decentralized, event-driven interactions without a central orchestrator. Question 21. Which infrastructure component is essential for deploying containerized applications? A) Virtual machines only B) Container runtime like Docker and orchestration platforms like Kubernetes C) Physical servers without virtualization D) Monolithic deployment scripts Answer: B
