Question 1

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?

A : 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

B : In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment using a scatter-gather configured with a timeout, and then merge the responses

C : Invoke the system API deployed to the primary environment, and if it fails, invoke the system API deployed to the DR environment

D : Invoke ONLY the system API deployed to the primary environment, and add timeout and retry logic to avoid intermittent failures

Answer: A

Question 2

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 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 3

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?

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 4

An API implementation is deployed to CloudHub. What conditions can be alerted on using the default Anypoint Platform functionality, where the alert conditions depend on the end-to-end request processing of the API implementation?

A : When the API is invoked by an unrecognized API client

B : When a particular API client invokes the API too often within a given time period

C : When the response time of API invocations exceeds a threshold

D : When the API receives a very high number of API invocations

Answer: C

Question 5

When must an API implementation be deployed to an Anypoint VPC?

A : When the API Implementation must invoke publicly exposed services that are deployed outside of CloudHub in a customer- managed AWS instance

B : When the API implementation must be accessible within a subnet of a restricted customer-hosted network that does not allow public access

C : When the API implementation must be deployed to a production AWS VPC using the Mule Maven plugin

D : When the API Implementation must write to a persistent Object Store

Answer: A
