Question 1

A large lending company has developed an API to unlock data from a database server and web server. TheAPI has been deployed to Anypoint Virtual Private Cloud(VPC) on CloudHub 1.0.The database server and web server are in the customer's secure network and are not accessible through thepublic internet. The database server is in the customer's AWSVPC, whereas the web server is in the customer's on-premises corporate data center.How can access be enabled for the API to connect with the database server and the web server?

Options :

A : Set up VPC peering with AWS VPC and a VPN tunnel to the customer-s on-premises corporate data center

B : Set up VPC peering with AWS VPC and the customer-s on-premises corporate data center

C : Setup a transit gateway to the customer-s on-premises corporate data center through AWS VPC

D : Set up VPC peering with the customer-s on-premises corporate data center and a VPN tunnel to AWS VPC

Answer: A

Question 2

An eCommerce company is adding a new Product Details feature to their website, A customer will launch theproduct catalog page, a new Product Details link willappear by product where they can click to retrieve the product detail description. Product detail data isupdated with product update releases, once or twice a year, Presentlythe database response time has been very slow due to high volume.What action retrieves the product details with the lowest response time, fault tolerant, and consistent data?

Options :

A : Select the product details from a database in a Cache scope and return them within the API response

B : Select the product details from a database and put them in Anypoint MQ; the Anypoint MO subseriber will receive the product details and return them within the API response

C : Use an object store to store and retrieve the product details originally read from a database and return them within the API response

D : Select the product details from a database and return them within the API response

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

The implementation of a Process API must change. What is a valid approach that minimizes the impact of this change on API clients?

Options :

A : Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition

B : Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version

C : Implement required changes to the Process API implementation so that whenever possible, the Process API-s RAML definition remains unchanged

D : Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanently to inform API clients they should be calling the new API implementation

Answer: C

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
