    Question

    Which of the following is a primary advantage of a

    microservices architecture compared to a monolithic architecture? 
    A Easier to deploy the entire system at once Correct Answer Incorrect Answer
    B Improved fault isolation and scalability Correct Answer Incorrect Answer
    C Reduced resource consumption for small-scale applications Correct Answer Incorrect Answer
    D Simpler data consistency and transaction management Correct Answer Incorrect Answer
    E Centralized management of all application modules Correct Answer Incorrect Answer

    Solution

    A primary advantage of microservices architecture is its improved fault isolation and scalability. In microservices, individual services function independently, so if one service fails, it doesn’t necessarily bring down the entire application. This modular structure also enables independent scaling of services based on demand, making microservices ideal for applications with diverse and fluctuating workloads. In contrast, monolithic applications tightly integrate components, leading to challenges in scaling specific parts of the system and greater risk that a single failure could impact the whole application. Scalability and fault isolation are significant factors in choosing microservices, particularly for large, complex systems requiring high reliability and resilience. Option A - Deploying the entire system at once is easier in monolithic architectures, as they are single-deployment units. Option C - Microservices can increase resource consumption due to inter-service communication, especially for smaller applications. Option D - Data consistency and transaction management are simpler in monolithic architectures, as all components operate within a unified system. Option E - Centralized management applies more to monolithic systems, where all modules are integrated.
