Question 1

How are the API implementation , API client, and API consumer combined to invoke and process an API ?

Options :

A : The API consumer creates an API implementation , which receives API invocations from an API such that they are processed for an API client

B : The API consumer creates an API client which sends API invocations to an API such that they are processed by an API implementation

C : An API client creates an API consumer, which receives API invocation from an API such that they are processed for an API implementation

D : The API client creates an API consumer which sends API invocations to an API such that they are processed by API implementation

Answer: C

Question 2

An external REST client periodically sends an array of records in a single POST request to a Mule application API endpoint. The Mule application must validate each record of the request against a JSON schema before sending it to a downstream system in the same order that it was received in the array Record processing will take place inside a router or scope that calls a child flow. The child flow has its own error handling defined. Any validation or communication failures should not prevent further processing of the remaining records. To best address these requirements what is the most idiomatic(used for it intended purpose) router or scope to used in the parent flow, and what type of error handler should be used in the child flow?

Options :

A : First Successful router in the parent flow On Error Continue error handler in the child flow

B : For Each scope in the parent flow On Error Continue error handler in the child flow

C : Parallel For Each scope in the parent flow On Error Propagate error handler in the child flow

D : Until Successful router in the parent flow On Error Propagate error handler in the child flow

Answer: B

Question 3

An organization has decided on a cloudhub migration strategy that aims to minimize the organizations own IT resources. Currently, the organizational has all of its Mule applications running on its own premises and uses an premises load balancer that exposes all APIs under the base URL https://api.acme.com As part of the migration strategy, the organization plans to migrate all of its Mule applications and load balancer to cloudhub What is the most straight-forward and cost effective approach to the Mule applications deployment and load balancing that preserves the public URLs?

Options :

A : Deploy the Mule applications to Cloudhub Update the CNAME record for an api.acme.com in the organizations DNS server pointing to the A record of a cloudhub dedicated load balancer(DLB) Apply mapping rules in the DLB to map URLs to their corresponding Mule applications

B : For each migrated Mule application, deploy an API proxy Mule application to Cloudhub with all applications under the control of a dedicated load balancer(CLB) Update the CNAME record for api.acme.com in the organization DNS server pointing to the A record of a cloudhub dedicated load balancer(DLB) Apply mapping rules in the DLB to map each API proxy application to its corresponding Mule applications

C : Deploy the Mule applications to Cloudhub Create CNAME record for api.acme.com in the Cloudhub Shared load balancer (SLB) pointing to the A record of the on-premise load balancer Apply mapping rules in the SLB to map URLs to their corresponding Mule applications

D : Deploy the Mule applications to Cloudhub Update the CNAME record for api.acme.com in the organization DNS server pointing to the A record of the cloudhub shared load balancer(SLB) Apply mapping rules in the SLB to map URLs to their corresponding Mule applications.

Answer: A

Question 4

According to MuleSoft, a synchronous invocation of a RESTful API using HTTP to get an individual customer record from a single system is an example of which system integration interaction pattern?

Options :

A : Request-Reply

B : Multicast

C : Batch

D : One-way

Answer: A

Question 5

Options :

A : Validate the API specification

B : Use the API specification to build the MuleSoft application

C : Design the API specification

D : Use the API specification to monitor the MuleSoft application
