A database Address table contains a ZIPCODE column and an increasing ID column. The Address table currently contains four (4) records. The On Table Row Database listener is configured with its watermark set to the Address table's ZIPCODE column and then the Mule application is run in Anypoint Studio for the first time, and the On Table Row Database listener palls the Address table.
Anew row is added to the database with ID=5 and ZIPCODE=90006, and then the On Table Row Database listener polls the database again.
After the next execution of the On Table Row Database listener polling, which database rows have been processed by the Mule flow since the Mule application was started?

Question Image

A ID ZIPCODE -1 900012 900053 90009

The Mule application configures and uses two HTTP Listener global configuration elements. The Mule application is run in Anypoint Studio.

Question Image

A The Mule application starts successfully.Web client requests can only be received at the URI / on port 2222, not on port 3333.
B The Mule application fails to start.There is a port bind conflict because the HTTP Request also uses port 3333.
C The Mule application starts successfully.Web client requests can be received at the URI / on port 2222 or port 3333.
D The Mule application fails to start.There is a URL path conflict because both HTTP Listeners are configured with the same path.
