Question 1

An existing Quoting API is defined in RAML and used by REST clients for interacting with the quoting engine. Currently there is a resource defined in the RAML that allows the creation of quotes; however, a new requirement was just received to allow for the updating of existing quotes.
Which two actions need to be taken to facilitate this change so it can be processed?
Choose 2 answers

A. Add a new API policy to API Manager to allow access to the updated endpoint

B. Update the API implementation to accommodate the new update request

C. Remove the old client applications and create new client applications to account for the changes

D. Deprecate existing versions of the API in Exchange

E. Update the RAML with new method details for the update request

Question 3

A Mule application exposes an HTTPS endpoint and is deployed to three CloudHub workers that do not use static IP addresses. The Mule application expects a high volume of client requests in short time periods. What is the most cost-effective infrastructure component that should be used to serve the high volume of client requests?

A. A customer-hosted load balancer

B. Runtime Manager autoscaling

C. An API proxy

D. The CloudHub shared load balancer

Question 4

A company stores financial transaction data in two legacy systems. For each legacy system, a separate, dedicated System API (SAPI) exposes data for that legacy system. A Process API (PAPI) merges the data retrieved from ail of the System APIs into a common format. Several API clients call the PAPI through its public domain name.
The company now wants to expose a subset of financial data to a newly developed mobile application that uses a different Bounded Context Data Model. The company wants to follow MuleSoft's best practices for building out an effective application network.
Following MuleSoft's best practices, how can the company expose financial data needed by the mobile application in a way that minimizes the impact on the currently running API clients, API implementations, and support asset reuse?

A. Add two new Experience APIs (EAPI-i and EAPI-2}.
Add Mobile PAPI-2 to expose the Intended subset of financial data as requested.
Both PAPIs access the Legacy Systems via SAPI-1 and SAP]-2.

B. Create a new mobile Experince API (EAPI) chat exposes that subset of PAPI endpoints.
Add transformtion login to the mobile Experince API implementation to make mobile data compatible with the required PAPIs.

C. Develop and deploy is new PAPI implementation with data transformation and ... login to support this required endpoints of both mobile and web clients.
Deploy an API Proxy with an endpoint from API Manager that redirect the existing PAPI endpoints to the new PAPI.

D. Add two new Experience APIs (EAPI-i and EAPI-2}.
Add Mobile PAPI-2 to expose the Intended subset of financial data as requested.
Both PAPIs access the Legacy Systems via SAPI-1 and SAP]-2.

Question 5

What is typically NOT a function of the APIs created within the framework called API-led connectivity?

A. They can compose data from various sources and combine them with orchestration logic to create higher level value.

B. They allow for innovation at the user Interface level by consuming the underlying assets without being aware of how data Is being extracted from backend systems.

C. They provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.

D. They reduce the dependency on the underlying backend systems by helping unlock data from backend systems In a reusable and consumable way.

Question 7

Which scenario is suited for MUnit tests instead of integration tests?

A. For read-only interactions to any dependencies (such as other web APIs)

B. When testing does not require knowledge of implementation details

C. For tests that are implemented using SoapUI

Question 8

An Order API triggers a sequence of other API calls to look up details of an order's items in a back-end inventory database. The Order API calls the OrderItems process API, which calls the Inventory system API.
The Inventory system API performs database operations in the back-end inventory database.
The network connection between the Inventory system API and the database is known to be unreliable and hang at unpredictable times.
Where should a two-second timeout be configured in the API processing sequence so that the Order API never waits more than two seconds for a response from the Orderltems process API?

A. In the inventory database

B. In the Order API implementation

C. In the Orderltems process API implementation

D. In the Inventory system API implementation

Question 9

A large company wants to implement IT infrastructure in its own data center, based on the corporate IT policy requirements that data and metadata reside locally.
Which combination of Mule control plane and Mule runtime plane(s) meets the requirements?

A. The MuleSoft-hosted control plane and Anypoint Runtime Fabric for the runtime plane

B. Anypoint Platform Private Cloud Edition for the control plane and the MuleSoft-hosted runtime plane

C. The MuleSoft-hosted control plane and customer-hosted Mule runtimes for the runtime plane

D. Anypoint Platform Private Cloud Edition for the control plane and customer-hosted Mule runtimes for the runtime plane

Question 11

In an organization, the InfoSec team is investigating Anypoint Platform related data traffic.
From where does most of the data available to Anypoint Platform for monitoring and alerting originate?

A. From the Mule runtime or the API implementation, depending on the deployment model
