Question 1

An organization has implemented a Customer Address API to retrieve customer address information. This API has been deployed to multiple environments and has been configured to enforce client IDs everywhere. A developer is writing a client application to allow a user to update their address. The developer has found the Customer Address API in Anypoint Exchange and wants to use it in their client application. What step of gaining access to the API can be performed automatically by Anypoint Platform?

Options :

A : Approve the client application request for the chosen SLA tier

B : Request access to the appropriate API Instances deployed to multiple environments using the client application-s credentials

C : Modify the client application to call the API using the client application-s credentials

D : Create a new application in Anypoint Exchange for requesting access to the API

Answer: A

Question 2

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?

Options :

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 3

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 4

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?

Options :

A : Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries

B : Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete

C : No timeout is possible to meet the upstream API-s desired SLA; a different SLA must be negotiated 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 it responds

Answer: B

Question 5

What is most likely NOT a characteristic of an integration test for a REST API implementation?

Options :

A : The test needs all source and/or target systems configured and accessible

B : The test runs immediately after the Mule application has been compiled and packaged

C : The test is triggered by an external HTTP request

D : The test prepares a known request payload and validates the response payload

Answer: B
