Correct answer: A, D, E

Explanation

Option A is correct because microservices are designed to allow easy replacement of individual functionalities. Option D is true as microservices can introduce network latency, making their interactions slower than those in a monolithic system. Option E is also correct; one of the main benefits of microservices is their ability to be updated and redeployed independently. Options B and C are incorrect as microservices can scale with multiple instances and integration tests can be carried out incrementally.
