Set the watermark column to the user_Id column
D.
Set the watermark column to the user_Id column
Answers
Suggested answer: A

Explanation:

* Watermark allows the poll scope to poll for new resources instead of getting the same resource over and over again.

* The database table must be ordered so that the ''watermark functionality'' can move effectively in the ordered list. Watermark stores the current/last picked up ''record id.''

* If the Mule application is shut down, it will store the last picked up ''record id'' in the Java Object Store and the data will continue to exist in the file. This watermark functionality is valuable and enables developers to have increased transparency.

* Developers do not need to create code to handle caching; it is all configurable!

* There are two columns and both are unique but user_id can't guaranty sequence whereas date_time will always be in increasing order and table content can easily be ordered on the basis of last processed date_time.

So correct answer is: Set the watermark column to the date_time column

Answers
Suggested answer: D

Explanation:

As can be seen in RAML, POST expects input in application/json format which eliminates two of the options as two options are in xml format.

Now out of the two remaining options, one has id field in request which is only mentioned for get response and not for POST request. Hence id field is not expected in POST request.

Hence correct answer is

{

'name': 'GoerdiLa Forge',

'address': '1 Westland CA',

'customer_since': '2014-01-04',

'balance': '4829.29',

'bank_agend_id': '12556'

}

Suggested answer: D

Explanation:

Flow Reference Component

Flow Reference routes the Mule event to another flow or subflow, executes all processors in the referenced flow, and then routes the event back within the same Mule application. The following diagram shows the order of processing when one flow references another:

When the main flow is triggered, the Mule event travels through and executes the flow until the event reaches the Flow Reference. The event then travels through and executes the referenced flow from beginning to end, and then returns to the main flow.

This process enables you to treat the entire referenced flow like a single component in your current flow.

Mule Ref Doc :https://docs.mulesoft.com/mule-runtime/4.3/flowref-about

Correct answer is

payload

quantity var

color query param
