Answer: B

Question 2

The Line of Business (LoB) of an eCommerce company is requesting a process that sends automatednotifications via email every time a new order is processed through thecustomer's mobile application or through the internal company's web application. In the future, multiplenotification channels may be added: for example, text messages andpush notifications.What is the most effective API-led connectivity approach for the scenario described above?

Options :

A : Create one Experience API for the web application and one for the mobile application.Create a Process API to orchestrate and retrieve the email template from = database.Create a System API that sends the email using the Anypoint Connector for Email.Create one Experience API for the web application and one for the mobile application.Create a Process API to orchestrate and retrieve the email template from = database.Create a System API that sends the email using the Anypoint Connector for Email.

B : Create one Experience API for the web application and one for the mobile application,Create a Process API to orchestrate, retrieve the email template from a database, and send the emailusing the Anypoint Connector for Email.

C : Create Experience APIs for both the web application and mobile application.Create a Process API ta orchestrate, retrieve the email template from e database, and send the emailusing the Anypoint Connector for Email.

D : Create Experience APIs for both the web application and mobile application.(Create 3 Process API to orchestrate and retrieve the email template from 2 databese. Create a System API that sends the email using the Anypoint Connector for Email.

Answer: A

Question 3

In which layer of API-led connectivity, does the business logic orchestration reside?

Options :

A : System Layer

B : Experience Layer

C : Process Layer

Answer: C

Question 4

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?

Options :

A : Convince the development team of the Product API to adopt the API data model of the Order API such that the integration logic of the Order API can work with one consistent internal data model

B : Work with the API data types of the Product API directly when implementing the integration logic of the Order API such that the Order API uses the same (unchanged) data types as the Product API

C : Implement an anti-corruption layer in the Order API that transforms the Product API data model into internal data types of the Order API

D : Start an organization-wide data modeling initiative that will result in an Enterprise Data Model that will then be used in both the Product API and the Order API

Answer: C

Question 5

Mule applications that implement a number of REST APIs are deployed to their own subnet that is inaccessible from outside the organization. External business-partners need to access these APIs, which are only allowed to be invoked from a separate subnet dedicated to partners - called Partner-subnet. This subnet is accessible from the public internet, which allows these external partners to reach it. Anypoint Platform and Mule runtimes are already deployed in Partner-subnet. These Mule runtimes can already access the APIs. What is the most resource-efficient solution to comply with these requirements, while having the least impact on other applications that are currently using the APIs?

Options :

A : Implement (or generate) an API proxy Mule application for each of the APIs, then deploy the API proxies to the Mule runtimes

B : Redeploy the API implementations to the same servers running the Mule runtimes

C : Add an additional endpoint to each API for partner-enablement consumption

D : Duplicate the APIs as Mule applications, then deploy them to the Mule runtimes
