Question # 8

Which layer in the API-led connectivity focuses on unlocking key systems, legacy systems, data sources etc and exposes the functionality? 
 

A. Experience Layer
B. Process Layer
C. System Layer

Answer: C
Explanation: Explanation Correct Answer: System Layer

The APIs used in an API-led approach to connectivity fall into three categories:System APIs – these usually access the core systems of record and provide a means ofinsulating the user from the complexity or any changes to the underlying systems. Oncebuilt, many users, can access data without any need to learn the underlying systems andcan reuse these APIs in multiple projects.Process APIs – These APIs interact with and shape data within a single system or acrosssystems (breaking down data silos) and are created here without a dependence on thesource systems from which that data originates, as well as the target channels throughwhich that data is delivered.Experience APIs – Experience APIs are the means by which data can be reconfigured sothat it is most easily consumed by its intended audience, all from a common data source,rather than setting up separate point-to-point integrations for each channel. An ExperienceAPI is usually created with API-first design principles where the API is designed for thespecific user experience in mind.

An Order API must be designed that contains significant amounts of integration logic and involves the invocation of the Product API. The power relationship between Order API and Product API is one of "Customer/Supplier", because the Product API is used heavily throughout the organization and is developed by a dedicated development team located in the office of the CTO. What strategy should be used to deal with the API data model of the Product API within the Order API? 
 

A. Convince the development team of the Product API to adopt the API data model of theOrder API such that the integration logic of the Order API can work with one consistentinternal data model
B. Work with the API data types of the Product API directly when implementing theintegration logic of the Order API such that the Order API uses the same (unchanged) datatypes as the Product API
C. Implement an anti-corruption layer in the Order API that transforms the Product API datamodel into internal data types of the Order API
D. Start an organization-wide data modeling initiative that will result in an Enterprise DataModel that will then be used in both the Product API and the Order API

Question # 12

A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity. The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms. If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA? 
 

A. Set a timeout of 50 ms; this times out more invocations of that API but gives additionalroom for retries
B. Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs tocomplete
C. No timeout is possible to meet the upstream API's desired SLA; a different SLA must benegotiated with the first downstream API or invoke an alternative API
D. Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until itresponds

A. Update the RAML definition of the current Process API and notify API client developersby sending them links to the updated RAML definition
B. Postpone changes until API consumers acknowledge they are ready to migrate to a newProcess API or API version
C. Implement required changes to the Process API implementation so that wheneverpossible, the Process API's RAML definition remains unchanged
D. Implement the Process API changes in a new API implementation, and have the old APIimplementation return an HTTP status code 301 - Moved Permanently to inform API clientsthey should be calling the new API implementation

Question # 14

What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST APIs, Anypoint CU, or the Mule Maven plugin? 
 

A. Access to Anypoint Platform APIs and Anypoint CU can be controlled separately through the roles and permissions in Anypoint Platform, so that specific users can getaccess to Anypoint CLI white others get access to the platform APIs
B. Anypoint Platform APIs can ONLY automate interactions with CloudHub, while the MuleMaven plugin is required for deployment to customer-hosted Mule runtimes
C. By default, the Anypoint CLI and Mule Maven plugin are NOT included in the Muleruntime, so are NOT available to be used by deployed Mule applications
D. API policies can be applied to the Anypoint Platform APIs so that ONLY certain LOBshave access to specific functions

Question # 15

What is the best way to decompose one end-to-end business process into a collaboration of Experience, Process, and System APIs?

 

A. Option A
B. Option B
C. Option C
D. Option D

Answer: B
Explanation: ExplanationCorrect Answer: Allow System APIs to return data that is NOT currently required by theidentified Process or Experience APIs.*****************************************>> All customizations for the end-user application should be handled in "Experience API"only. Not in Process API>> We should use tiered approach but NOT always by creating exactly one API for each ofthe 3 layers. Experience APIs might be one but Process APIs and System APIs are oftenmore than one. System APIs for sure will be more than one all the time as they are thesmallest modular APIs built in front of end systems.>> Process APIs can call System APIs as well as other Process APIs. There is no suchanti-design pattern in API-Led connectivity saying Process APIs should not call otherProcess APIs.So, the right answer in the given set of options that makes sense as per API-Ledconnectivity principles is to allow System APIs to return data that is NOT currently requiredby the identified Process or Experience APIs. This way, some future Process APIs canmake use of that data from System APIs and we need NOT touch the System layer APIsagain and again.
