NEW QUESTION # 31
Which of the following is the most efficient service concept for resource usage?
- A. Stateless
- B. Stateful
- C. Serverless
Answer: A
Explanation:
The "Stateless" service concept is indeed the most efficient for resource usage. In a stateless architecture, each request is treated as an independent transaction, unconnected to any previous request. This means that no state information is stored between transactions, which simplifies the design and scalability of systems. It allows for better resource utilization because there is no need to maintain state information over time, which can be resource-intensive. This approach aligns with the principles of RESTful services and is widely adopted in scalable web applications.

- A. Very fast deployment
- B. Fixed capacity
- C. Very light weight application
- D. Low scalability
Answer: B,D
Explanation:
The characteristics of traditional monolithic services are low scalability and fixed capacity. Monolithic services are applications that are built as a single unit, where all the components are tightly coupled and run in the same process. This makes them hard to scale, as they require more resources and coordination to handle increased demand. Monolithic services also have fixed capacity, as they are designed for a specific workload and cannot adapt to changing requirements or traffic patterns. Monolithic services are often slow to deploy, as they require updating the entire application for any change or improvement.
