A leading e-commerce giant will use Mulesoft API's on runtime fabric (RTF) to process customer orders.
Some customer's sensitive information such as credit card information is also there as a part of a API payload.
What approach minimizes the risk of matching sensitive data to the original and can convert back to the original value whenever and wherever required?

• A. Apply masking to hide the sensitive information and then use API
• B. Used both masking and tokenization
• C. manager to detokenize the masking format to return the original value
• D. create a tokenization format and apply a tokenization policy to the API Gateway
• E. Apply a field level encryption policy in the API Gateway

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 DataWeave map operation and an Async scope to insert records one by one into the database.
• C. Use a Scatter-Gather to bulk insert records into the database
• D. Use a Batch job scope to bulk insert records into the database.

An API implementation is being designed that must invoke an Order API which is known to repeatedly experience downtime. For this reason a fallback API is to be called when the Order API is unavailable. What approach to designing invocation of the fallback API provides the best resilience?

• A. Set an option in the HTTP Requester component that invokes the order API to instead invoke a fallback API whenever an HTTP 4XX or 5XX response status code is received from Order API
• B. Search Anypoint Exchange for a suitable existing fallback API and them implement invocations to their fallback API in addition to the Order API
• C. Redirect client requests through an HTTP 303 temporary redirect status code to the fallback API whenever the Order API is unavailable
• D. Create a separate entry for the order API in API manager and then invoke this API as a fallback API if the primary Order API is unavailable

How does timeout attribute help inform design decisions while using JMS connector listening for incoming messages in an extended architecture (XA) transaction?

• A. The timeout defines the time that is allowed to pass without the transaction ending explicitly and after the timeout expires, the transaction rolls back
• B. The time allowed to pass between committing the transaction and the completion of the mule flow and then after the timeout flow processing triggers an error
• C. The timeout specifies the time allowed to pass between receiving JMS messages on the same JMS connection and then after the timeout new JMS connection is established
• D. After the timeout is exceeded, stale JMS consumer threads are destroyed and new threads are created

A company is building an application network and has deployed four Mule APIs: one experience API, one process API, and two system APIs. The logs from all the APIs are aggregated in an external log aggregation tool. The company wants to trace messages that are exchanged between multiple API implementations. What is the most idiomatic (based on its intended use) identifier that should be used to implement Mule event tracing across the multiple API implementations?

• A. Client's IP address
• B. Mule correlation ID
• C. Mule event ID
• D. DataWeave UUID
