To collect a representative sample from a larger data set, the developer should use the NTILE (C) SQL function. The NTILE function is used to distribute rows into a specified number of approximately equal-sized buckets or tiles, which can be useful for sampling purposes.

Example usage:

SELECT * FROM ( SELECT *, NTILE(10) OVER (ORDER BY SomeField) AS TileNumber FROM LargeDataSet ) AS Sample WHERE TileNumber = 1

This query divides the dataset into 10 tiles and selects rows from the first tile, effectively providing a sample.

Exclusion Scripts are used to exclude subscribers from email sends based on specific criteria. This functionality can be applied in various sending scenarios within Salesforce Marketing Cloud.

Journey Builder Send Email Activity: In Journey Builder, exclusion scripts can be applied to Email Activities to ensure specific subscribers are excluded based on the business rules.

The outdated subject line variable could be located in the HTML body which is processed after the subject line (D). This is because AMPscript variables declared in the HTML body can affect the overall email content, including the subject line, and if not updated, they can cause discrepancies in the displayed subject line.

To inject contacts into a journey using the REST API, the correct endpoints involve the event definitions and events.

POST /eventDefinitions/key:{key} or /eventDefinitions/{id}: This endpoint allows you to interact with event definitions by key or ID, which is essential for managing journey events.

POST /interaction/v1/events: This endpoint is used to inject events into the journey, thus adding contacts to the journey based on the defined event.

To convert a string payload in JSON format to a JavaScript object on a CloudPage, the developer should use the ParseJSON (B) function in Marketing Cloud Server-Side JavaScript (SSJS). This function parses a JSON string and returns a corresponding JavaScript object.

Example:

var jsonString = '{"key1":"value1", "key2":"value2"}'; var jsonObject = Platform.Function.ParseJSON(jsonString);

The newly created data model in Contact Builder can be used for segmentation in the following applications:

Email Studio (A) - Email Studio can use data extensions and attribute groups from Contact Builder for segmentation.

Journey Builder (C) - Journey Builder can leverage the data model created in Contact Builder for creating targeted journeys and audience segments.

To programmatically inject Contacts into a journey via the REST API, the recommended route is /interaction/v1/events. This endpoint allows you to trigger an event which can be configured to start a journey for the specified contacts.

The RedirectTo AMPscript function prevents link href values from getting recorded in tracking (C). When RedirectTo is used, it bypasses the standard link wrapping and tracking process, causing the link click not to be captured in the tracking data.

To alternate the background color of rows in an HTML table using AMPscript, the MOD function can be used to determine if the row number is odd or even.

MOD Function: The MOD function returns the remainder of a division operation. By using MOD(@numerator, 2), the function returns 1 for odd rows and 0 for even rows, allowing the background color to be set accordingly.

AMPscript Example:

%%[ SET @numerator = 1 FOR @i = 1 TO RowCount(@rows) DO SET @color = IF MOD(@numerator, 2) == 1 THEN 'Red' ELSE 'White' ENDIF SET @numerator = ADD(@numerator, 1) ]%% %%[ NEXT @i ]%%
