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?

Question 12

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.

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)

Question 15

A Mule application is running on a customer-hosted Mule runtime in an organization's network. The
Mule application acts as a producer of asynchronous Mule events. Each Mule event must be
broadcast to all interested external consumers outside the Mule application. The Mule events should
be published in a way that is guaranteed in normal situations and also minimizes duplicate delivery
in less frequent failure scenarios.
The organizational firewall is configured to only allow outbound traffic on ports 80 and 443. Some
external event consumers are within the organizational network, while others are located outside
the firewall.
