質問 # 141
A Database On Table Row listener retrieves data from a CUSTOMER table that contains a primary key userjd column and an increasing kxjin_date_time column. Neither column allows duplicate values.
How should the listener be configured so it retrieves each row at most one time?

A. Set the watermark column to the user_Id column
B. Set the target value to the last retrieved login_date_time value
C. Set the target value to the last retrieved user_jd value
D. Set the watermark column to the bgin_date_time column

正解：D

解説：
* 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

A. Creates a separate flow for each HTTP method
B. Creates a separate flow for each resource that contains child resources

質問 # 144
What DataWeave expression transforms the array a to the XML output?

A. 1. 1. {
2. 2. trains:

4. 4. train: {
5. 5. TrainNumber: engId
6. 6.
7. 7. }
8. 8. )
9. }
B. 1. 1. trains:
2. 2. {(
3. 3. a map ((engId, index) ->
4. 4. train: {
5. 5. TrainNumber: engId
6. 6.
7. 7. }
8. 8. )
9. 9. )}
C. 1. 1. trains:
2. 2. a map ((engId, index) ->
3. 3. train: {
4. 4. TrainNumber: engId
5. 5.
6. 6. }
7. 7. )
D. 1. 1. {(
2. 2. trains:
3. 3. a map ((engId, index) ->
4. 4. train: {
5. 5. TrainNumber: engId
6. 6.
7. 7. }
8. 8. )
9. )}

正解：B

解説：
For such questions always look for Syntax:
I call it "Wrap the Map"
trains:
{(
When mapping array elements (JSON or JAVA) to XML, wrap the map operations in {(..)}
-{ } are defining the object
-( ) are transforming each element in the array as a key/value pair

質問 # 146
Refer to the exhibit.

What is a valid expression for the Choice router's when expression to route events to the documenticShipping flow?

A. 0#[ payload = 'US' ]
B. #[ if(payload = 'US') J
C. #[ payload == 'US' J
D. #[ if(payload == "US") ]

正解：C

解説：
Choice Router
The Choice router dynamically routes messages through a flow according to a set of DataWeave expressions that evaluate message content. Each expression is associated with a different routing option. The effect is to add conditional processing to a flow, similar to an if/then/else code block in most programming languages.
Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route's execution and the others are not checked. If none of the expressions are true, then the default route executes.
Properties of <when>
PropertyDescription
Expression (expression)
Expression in DataWeave language to evaluate input.
If the expression evaluates to true, this routing option is used:
<when expression="#[vars.language == 'Spanish']" >
Mulesoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/choice-router-concept With respect to above information , Option 1 is the correct syntax as others are incorrect because of below reasons
* Single = is not the correct syntax to validate the condition. It should be ==
* If keyword is not required in when condition.

質問 # 147
Refer to the exhibit.

All three of the condition for the Choice router are true. What log messages are written?

A. Route2
B. Route 1
C. Route1, Route2, Default
D. Route1, Route2

正解：B

質問 # 148
Refer to exhibits.

What message should be added to Logger component so that logger prints "The city is Pune" (Double quote should not be part of logged message)?

A. #["The city is" ++ payload.City]
B. The city is + #[payload.City]
C. #[The city is ${payload.City}
D. The city is #[payload.City]

正解：D

解説：
Correct answer is The city is #[payload.City]
Answer can get confused with the option #["The city is" ++ payload.City] But note that this option will not print the space between is and city name. This will print The city isPune

A. attributes.booklSBN
B. vars. booklSBN
C. booklSBN
D. flowVars.booklSBN

質問 # 153
In the Database On Table Row operation, what does the Watermark column enable the On Table Row operation to do?

A. To avoid duplicate processing of records in a database.
B. To delete the most recent records retrieved from a database to enable database caching
C. To enable duplicate processing of records in a database
D. To save the most recent records retrieved from a database to enable database caching

正解：A

解説：
The correct answer is To avoid duplicate processing of records in a database.
If a watermark column is provided, the values taken from that column are used to filter the contents of the next poll, so that only rows with a greater watermark value are returned. If an ID column is provided, this component automatically verifies that the same row is not picked twice by concurrent polls.
