Question 1

An external web UI application currently accepts occasional HTTP requests from client web browsers to change (insert, update, or delete) inventory pricing information in an inventory system's database. Each inventory pricing change must be transformed and then synchronized with multiple customer experience systems in near real-time (in under 10 seconds). New customer experience systems are expected to be added in the future. The database is used heavily and limits the number of SELECT queries that can be made to the database to 10 requests per hour per user. What is the most scalable, idiomatic (used for its intended purpose), decoupled. reusable, and maintainable integration mechanism available to synchronize each inventory pricing change with the various customer experience systems in near real-time?

Options :

A : Write a Mule application with a Database On Table Row event source configured for the inventory pricing database, with the watermark attribute set to an appropriate database column In the same now, use a Scatter-Gather to call each customer experience system-s REST API with transformed inventory-pricing records

B : Add a trigger to the inventory-pricing database table so that for each change to the inventory pricing database, a stored procedure is called that makes a REST call to a Mule application Write the Mule application to publish each Mule event as a message to an Anypoint MQ exchange Write other Mule applications to subscribe to the Anypoint MQ exchange, transform each received message, and then update the Mule application-s corresponding customer experience system(s)

C : Replace the external web UI application with a Mule application to accept HTTP requests from client web browsers In the same Mule application, use a Batch Job scope to test if the database request will succeed, aggregate pricing changes within a short time window, and then update both the inventory pricing database and each customer experience system using a Parallel For Each scope

D : Write a Mule application with a Database On Table Row event source configured for the inventory pricing database, with the ID attribute set to an appropriate database column In the same flow, use a Batch Job scope to publish transformed Inventory-pricing records to an Anypoint MQ queue Write other Mule applications to subscribe to the Anypoint MQ queue, transform each received message, and then update the Mule application-s corresponding customer experience system(s)

Answer: B

Question 2

According to MuleSoft, which system integration term describes the method, format, and protocol used for communication between two system?

Options :

A : Component

B : interaction

C : Message

D : Interface

Answer: D

Question 3

A leading bank implementing new mule API. The purpose of API to fetch the customer account balances from the backend application and display them on the online platform the online banking platform. The online banking platform will send an array of accounts to Mule API get the account balances. As a part of the processing the Mule API needs to insert the data into the database for auditing purposes and this process should not have any performance related implications on the account balance retrieval flow How should this requirement be implemented to achieve better throughput?

Options :

A : Implement the Async scope fetch the data from the backend application and to insert records in the Audit database

B : Implement a for each scope to fetch the data from the back-end application and to insert records into the Audit database

C : Implement a try-catch scope to fetch the data from the back-end application and use the Async scope to insert records into the Audit database

D : Implement parallel for each scope to fetch the data from the backend application and use Async scope to insert the records into the Audit database

Answer: C

Question 4

A mule application must periodically process a large dataset which varies from 6 GB lo 8 GB from a back-end database and write transform data lo an FTPS server using a properly configured bad job scope. The performance requirements of an application are approved to run in the cloud hub 0.2 vCore with 8 GB storage capacity and currency requirements are met. How can the high rate of records be effectively managed in this application?

Options :

A : Use streaming with a file storage repeatable strategy for reading records from the database and batch aggregator with streaming to write to FTPS

B : Use streaming with an in-memory reputable store strategy for reading records from the database and batch aggregator with streaming to write to FTPS

C : Use streaming with a file store repeatable strategy for reading records from the database and batch aggregator with an optimal size

D : Use streaming with a file store repeatable strategy reading records from the database and batch aggregator without any required configuration

Answer: A

Question 5

A retail company is implementing a MuleSoft API to get inventory details from two vendors by Invoking each vendor's online applications. Due to network issues, the invocations to the vendor applications are timing out intermittently, but the requests are successful after re-invoking each vendor application. What is the most performant way of implementing the API to invoke each vendor application and to retry invocations that generate timeout errors?

Options :

A : Use a For-Each scope to invoke the two vendor applications in series, one after the other Place the For-Each scope inside an Until-Successful scope to retry requests that raise timeout errors.

B : Use a Choice scope to Invoke each vendor application on a separate route. Place the Choice scope inside an Until-Successful scope to retry requests that raise timeout errors.

C : Use a Scatter-Gather scope to invoke each vendor application on a separate route. Use an Until-Successful scope in each route to retry requests that raise timeout errors.

D : Use a Round-Robin scope to invoke each vendor application on a separate route. Use a Try-Catch scope in each route to retry requests that raise timeout errors.
