Salesforce Marketing-Cloud-Developer - Salesforce Certified Marketing Cloud Developer (SP25)

To build out a series of CloudPages that will interact with several REST APIs, the developer should use SSJS (Server-Side JavaScript) (C). SSJS is supported in Marketing Cloud and provides robust capabilities for interacting with external APIs, handling HTTP requests, and processing data.

In Marketing Cloud, the Contact Key should be represented as a Text data type, even if it is a numeric value. This is because using the Text data type avoids issues related to numeric value formatting and allows for greater flexibility in handling the values.

In AMPscript, comments can be added within a code block using the /* comment */ syntax. This allows developers to include notes or explanations without affecting the execution of the script.

Example:

ampscript

Copy code

%%[ /* This is a comment */ SET @var = "value" ]%%

To track the performance of dynamically created content via AMPscript in an email, the following steps should be performed:

Request the Impression Tracking feature be enabled on the account: This feature must be enabled to track impressions of dynamic content.

Include the functions BeginImpressionRegion and EndImpressionRegion: These functions are used within the AMPscript code to mark the beginning and end of the content region that needs to be tracked.

Example:

ampscript

Copy code

%%[BeginImpressionRegion('DynamicContent')]%%

%%=v(@DynamicContent)=%%

To remove contacts mistakenly synced from the User_Salesforce object, the recommended approach is to put the synced records into a sendable data extension and use Contact Delete (C). This method allows for the systematic deletion of these contacts from the All Contacts table without affecting other data.

In the SOAP API response, the element that provides detailed information about the error, including missing required data extension fields, is ErrorDescription (A). This element contains a description of the error, helping developers understand and resolve the issue.

To create a query that aggregates clicks grouped by the language of the recipient, the developer needs to use Data Views that store subscriber and click information. The required Data Views are:

_Subscribers (A) - This Data View contains information about subscribers, including their profile attributes such as language.

_Click (D) - This Data View contains information about click events for email messages, which can be used to aggregate clicks.

The query would join these Data Views on a common identifier (e.g., SubscriberKey) and group the results by the language attribute.

When configuring a Send Log Data Extension, it is crucial to follow best practices to ensure efficient tracking and data management.

Use Data Retention: Implementing data retention policies helps manage the volume of data stored in the send log, improving performance and reducing storage costs.

Limit Custom Fields: Limiting the number of custom fields to 10 or fewer helps maintain the efficiency and performance of the data extension.

A Query Activity in an Automation can fail for several reasons, including:

The query takes more than 60 minutes to run (A) - Long-running queries are subject to timeouts, which can cause the query to fail.

The query results in duplicate rows not allowed by the primary key (C) - If the query attempts to insert duplicate rows into a data extension that has a primary key constraint, it will fail.

The query is inserting a value that is larger than the size of a field (E) - If the query attempts to insert data that exceeds the field size limits, it will result in an error.

In an Enterprise 2.0 account, when querying shared data extensions from a child business unit, the data extension name should be prefixed with 'ENT.' to indicate it resides in the shared data extensions folder.

Correct Query:

SELECT * FROM ENT.MemberData WHERE State = 'NY' AND US = 1
