Question 1

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 2

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?

Options :

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 3

Which two statements are true about the technology architecture of an Anypoint Virtual Private Cloud(VPC)?Choose 2 answers

Options :

A : Ports 8081 and 8082 are used

B : CIDR blacks are used

C : Anypoint VPC is responsible for load balancing the applications

D : Round-robin load balancing is used to distribute client requests across different applications

E : By default, HTTP requests can be made from the public internet to workers at port 6091

Answer: B,E

Question 4

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

Options :

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

Question 5

What CANNOT be effectively enforced using an API policy in Anypoint Platform?

Options :

A : Guarding against Denial of Service attacks

B : Maintaining tamper-proof credentials between APIs

C : Logging HTTP requests and responses

D : Backend system overloading
