Given that the application is designed to handle only one process at a time to maintain data consistency, here' s why horizontal scaling won't increase the processing limit:
* Single-Process Constraint:
* The application limits to processing one transaction at a time due to its design for consistency, meaning horizontal scaling (adding more workers) does not increase processing speed beyond this limit.
* Execution Time:
* Since each request takes 200 ms, five requests per second is the maximum processing threshold.
Increasing the number of workers does not bypass this single-process limitation.
* Explanation of Correct Answer (A):
* The scalability remains at five requests per second, as this constraint is intrinsic to the application' s design.
* Explanation of Incorrect Options:
* Option B suggests a change in execution time, which horizontal scaling does not affect.
* Option C assumes doubling the throughput, which isn't possible due to the single-threaded nature of the application.
* Option D suggests horizontal scaling cannot apply, which is incorrect; however, scaling does not increase throughput in this context.
