MuleSoft Certified Integration Architect - Level 1 Exam


Question 1

The AnyAirline organization's passenger reservations center is designing an integration solution that
combines invocations of three different System APIs (bookFlight, bookHotel, and bookCar) in a
business transaction. Each System API makes calls to a single database.
The entire business transaction must be rolled back when at least one of the APIs fails.
What is the most idiomatic (used for its intended purpose) way to integrate these APIs in near real-
time that provides the best balance of consistency, performance, and reliability?

  • A. Implement eXtended Architecture (XA) transactions between the API implementations Coordinate between the API implementations using a Saga pattern Implement caching in each API implementation to improve performance 109/110 Questions & Answers PDF P-
  • B. Implement local transactions within each API implementation Configure each API implementation to also participate in the same eXtended Architecture (XA) transaction Implement caching in each API implementation to improve performance
  • C. Implement local transactions in each API implementation Coordinate between the API implementations using a Saga pattern Apply various compensating actions depending on where a failure occurs
  • D. Implement an eXtended Architecture (XA) transaction manager in a Mule application using a Saga pattern Connect each API implementation with the Mule application using XA transactions Apply various compensating actions depending on where a failure occurs

Question 3

A marketing organization is designing a Mule application to process campaign dat
a. The Mule application will periodically check for a file in a SFTP location and process the records in
the file. The size of the file can vary from 10MB to 5GB. Due to the limited availabiltty of vCores, the
Mule application is deployed to a single CloudHub worker configured with vCore size 0.2.
The application must transform and send different formats of this file to three different downstream
SFTP locations.
What is the most idiomatic (used for its intended purpose) and performant way to configure the SFTP
operations or event sources to process the large files to support these deployment requirements?

Question 4

An organization has defined a common object model in Java to mediate the communication between
different Mule applications in a consistent way. A Mule application is being built to use this common
object model to process responses from a SOAP API and a REST API and then write the processed
results to an order management system.
The developers want Anypoint Studio to utilize these common objects to assist in creating mappings
for various transformation steps in the Mule application.
What is the most idiomatic (used for its intended purpose) and performant way to utilize these
common objects to map between the inbound and outbound systems in the Mule application?

  • A. Use JAXB (XML) and Jackson (JSON) data bindings
  • B. Use the WSS module
  • C. Use the Java module
  • D. Use the Transform Message component

Question 6

An organization is designing a Mule application to periodically poll an SFTP location for new files
containing sales order records and then process those sales orders. Each sales order must be
processed exactly once.
To support this requirement, the Mule application must identify and filter duplicate sales orders on
the basis of a unique ID contained in each sales order record and then only send the new sales orders
to the downstream system.
What is the most idiomatic (used for its intended purpose) Anypoint connector, validator, or scope
that can be configured in the Mule application to filter duplicate sales orders on the basis of the
unique ID field contained in each sales order record?

  • A. Configure a Cache scope to filter and store each record from the received file by the order ID
  • B. Configure a Database connector to filter and store each record by the order ID
  • C. Configure an Idempotent Message Validator component to filter each record by the order ID
  • D. Configure a watermark In an On New or Updated File event source to filter unique records by the order ID

Question 7

An organization is creating a Mule application that will be deployed to CloudHub. The Mule
application has a property named dbPassword that stores a database users password.
The organization's security standards indicate that the dbPassword property must be hidden from

Question 8

A Mule application is built to support a local transaction for a series of operations on a single
database. The Mule application has a Scatter-Gather that participates in the local transaction.
What is the behavior of the Scatter-Gather when running within this local transaction?

  • A. Execution of each route within the Scatter-Gather occurs sequentially Any error that occurs inside the Scatter-Gather will result in a rollback of all the database operations
  • B. Execution of all routes within the Scatter-Gather occurs in parallel Any error that occurs inside the Scatter-Gather will result in a rollback of all the database operations
  • C. Execution of each route within the Scatter-Gather occurs sequentially Any error that occurs inside the Scatter-Gather will NOT result in a rollback of any of the database operations
  • D. Execution of each route within the Scatter-Gather occurs in parallel Any error that occurs inside the Scatter-Gather will NOT result in a rollback of any of the database operations

Question 10

A Mule application is being designed for deployment to a single CloudHub worker. The Mule
application will have a flow that connects to a SaaS system to perform some operations each time
the flow is invoked.

(fifteen minutes) that can be reused for subsequent connections within the fifteen minute time
window. After the token expires, a new token must be requested and stored.

component or service to use to support persisting and reusing tokens in the Mule application to help
speed up reconnecting the Mule application to the SaaS application?

  • C. Variable
  • D. Database
