Salesforce Updated MuleSoft-Integration-Architect-I Exam Questions and Answers by renae

Explanation

* Object Store and VM Store is used for sharing data inter or intra mule applications in same setup. Can't be used with external Business Partner

* Also File connector will not be useful as the two companies currently have no shared IT infrastructure. It's specific for local use.

* Correct answer is SFTP connector. The SFTP Connector implements a secure file transport channel so that your Mule application can exchange files with external resources. SFTP uses the SSH security protocol to transfer messages. You can implement the SFTP endpoint as an inbound endpoint with a one-way exchange pattern, or as an outbound endpoint configured for either a one-way or request-response exchange pattern.

Explanation

* Setting a transaction timeout for the Bitronix transaction manager

● Set the transaction timeout either

– In wrapper.conf

– In CloudHub in the Properties tab of the Mule application deployment

● The default is 60 secs. It is defined as

mule.bitronix.transactiontimeout = 120

* This property defines the timeout for each transaction created for this manager.

If the transaction has not terminated before the timeout expires it will be automatically rolled back.

Additional Info around Transaction Management:

Bitronix is available as the XA transaction manager for Mule applications

● To use Bitronix, declare it as a global configuration element in the Mule application

● Each Mule runtime can have only one instance of a Bitronix transaction manager, which is shared by all Mule applications

● For customer-hosted deployments, define the XA transaction manager in a Mule domain

– Then share this global element among all Mule applications in the Mule runtime

The File Transfer Protocol (FTP) uses the Transmission Control Protocol (TCP) for reliable communication. TCP is one of the core protocols of the Internet Protocol Suite and provides reliable, ordered, and error-checked delivery of a stream of data between applications running on hosts communicating via an IP network. FTP relies on TCP to ensure that all data packets are delivered accurately and in the correct sequence, which is essential for the reliable transfer of files between a client and server.

Explanation

•Scatter Gather: When running within a transaction, Scatter Gather does not execute in parallel. This means that the second route is executed after the first one is processed, the third after the second one, etc. In case of error, all routes will be rolled back
