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?

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

As a part of project requirement, client will send a stream of data to mule application. Payload size can vary between 10mb to 5GB. Mule application is required to transform the data and send across multiple sftp servers. Due to the cost cuttings in the organization, mule application can only be allocated one worker with size of 0.2 vCore. As an integration architect , which streaming strategy you would suggest to handle this scenario?

A : In-memory non repeatable stream

B : File based non-repeatable stream

C : In-memory repeatable stream

D : File based repeatable storage

Answer: D

Question 3

A Mule application is being designed To receive nightly a CSV file containing millions of records from an external vendor over SFTP, The records from the file need to be validated, transformed. And then written to a database. Records can be inserted into the database in any order. In this use case, what combination of Mule components provides the most effective and performant way to write these records to the database?

A : Use a Parallel for Each scope to Insert records one by one into the database

B : Use a Scatter-Gather to bulk insert records into the database

C : Use a Batch job scope to bulk insert records into the database.

D : Use a DataWeave map operation and an Async scope to insert records one by one into the database.

Answer: C

Question 4

Additional nodes are being added to an existing customer-hosted Mule runtime cluster to improve performance. Mule applications deployed to this cluster are invoked by API clients through a load balancer. What is also required to carry out this change?

A : A new load balancer must be provisioned to allow traffic to the new nodes in a round-robin fashion

B : External monitoring tools or log aggregators must be configured to recognize the new nodes

C : API implementations using an object store must be adjusted to recognize the new nodes and persist to them

D : New firewall rules must be configured to accommodate communication between API clients and the new nodes

Answer: B

Question 5

Customer has deployed mule applications to different customer hosted mule run times. Mule applications are managed from Anypoint platform. What needs to be configured to monitor these Mule applications from Anypoint monitoring and what sends monitoring data to Anypoint monitoring?

A : Enable monitoring of individual applications from runtime manager application settings Runtime manager agent sends monitoring data from the mule applications to Anypoint monitoring

B : Install runtime manager agent on each mule runtime Runtime manager agent since monitoring data from the mule applications to Anypoint monitoring

C : Anypoint monitoring agent on each mule runtime Anypoint monitoring agent sends monitoring data from the mule applications to Anypoint monitoring

D : By default, Anypoint monitoring agent will be installed on each Mule run time Anypoint Monitoring agent automatically sends monitoring data from the Mule applications to Anypoint monitoring
