Which of the following best fits the definition of API-led connectivity?
Answer(s): A
Correct Answer: API-led connectivity is not just an architecture or technology but also a way to organize people and processes for efficient IT delivery in the organization.*****************************************

A system API has a guaranteed SLA of 100 ms per request. The system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. An upstream process API invokes the system API and the main goal of this process API is to respond to client requests in the least possible time. In what order should the system APIs be invoked, and what changes should be made in order to speed up the response time for requests from the process API?
Correct Answer: In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment, and ONLY use the first response.*****************************************>> The API requirement in the given scenario is to respond in least possible time. >> The option that is suggesting to first try the API in primary environment and then fallback to API in DR environment would result in successful response but NOT in least possible time. So, this is NOT a right choice of implementation for given requirement.>> Another option that is suggesting to ONLY invoke API in primary environment and to add timeout and retries may also result in successful response upon retries but NOT in least possible time. So, this is also NOT a right choice of implementation for given requirement. >> One more option that is suggesting to invoke API in primary environment and API in DR environment in parallel using Scatter-Gather would result in wrong API response as it would return merged results and moreover, Scatter-Gather does things in parallel which is true but still completes its scope only on finishing all routes inside it. So again, NOT a right choice of implementation for given requirementThe Correct choice is to invoke the API in primary environment and the API in DR environment parallelly, and using ONLY the first response received from one of them.
In which layer of API-led connectivity, does the business logic orchestration reside?
Correct Answer: Process Layer*****************************************>> Experience layer is dedicated for enrichment of end user experience. This layer is to meet the needs of different API clients/ consumers.>> System layer is dedicated to APIs which are modular in nature and implement/ expose various individual functionalities of backend systems>> Process layer is the place where simple or complex business orchestration logic is written by invoking one or many System layer modular APIsSo, Process Layer is the right answer.
The application network is recomposable: it is built for change because it "bends but does not break"
*****************************************>> Application Network is a disposable architecture.>> Which means, it can be altered without disturbing entire architecture and its components. >> It bends as per requirements or design changes but does not break
