To configure a data extension to store data for six months, you should update the data extension configuration to include data retention settings.

Data Retention Settings: You can configure data retention directly within the data extension settings in Email Studio to specify how long data should be retained. This ensures that data older than the specified period is automatically deleted.

Go to Email Studio -> Subscribers -> Data Extensions.

Select the data extension you want to configure.

Click on "Properties".

Under "Data Retention", set the retention period to six months and define the retention settings accordingly.

The Contact Delete process in Marketing Cloud removes contact data from the contact model but does not remove records from the data extensions themselves.

Contact Delete Process: When you perform a Contact Delete in Contact Builder, it removes the contact data from the contact model but leaves the actual rows in the data extensions intact.

Salesforce Contact Deletion Process

After using the messageDefinitionSends REST API endpoint to send a triggered send email, and receiving a 202 (success) response code, the developer can validate if the email was successfully sent by using the messageDefinitionSend/key:(key)/deliveryRecords REST endpoint with the GET method. This endpoint provides delivery records and allows verification of the email's delivery status.

Transparent Data Encryption (TDE) is the appropriate method for ensuring that the underlying database files are encrypted at rest. TDE encrypts the database files themselves, protecting the data in case the physical media is stolen, while allowing the data to be viewed in clear text by authorized users within the system.

Transparent Data Encryption: Encrypts data at rest, ensuring that the database files are secure.

Salesforce Transparent Data Encryption

The UpdateDE function in AMPscript updates the data extension rows as the emails are being sent. If the send is canceled and only 400 emails are sent, then only the 400 subscribers who received the email will have their data extension rows updated by the UpdateDE function.

Salesforce AMPscript UpdateDE Function

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.

Salesforce Send Log Data Extension

To identify all subscribers who were sent Job ID 420 but did not click any links, the developer should use a SQL statement that selects subscribers from the _Sent Data View where the Job ID is 420 and excludes those who are found in the _Click Data View. The correct SQL statement is:

SELECT s.SubscriberKey FROM _Sent s LEFT JOIN _Click c ON s.SubscriberKey = c.SubscriberKey AND s.JobID = c.JobID WHERE s.JobID = '420' AND c.SubscriberKey IS NULL

This query performs a left join between the _Sent and _Click data views and filters the results to include only those subscribers who do not have a corresponding click record.

To determine if a specific text string exists in a tab-delimited list of values, the BuildRowSetFromString AMPscript function is the most appropriate. This function splits the string into a rowset, making it easier to search for the specific text.

BuildRowSetFromString Function: This function converts a delimited string into a rowset, which can then be iterated over or searched using other AMPscript functions.

SET @values = "val1\tval2\tval3" SET @rowset = BuildRowSetFromString(@values, "\t") SET @rowCount = RowCount(@rowset) SET @found = "false" FOR @i = 1 TO @rowCount DO SET @row = Row(@rowset, @i) SET @value = Field(@row, 1) IF @value == "specificText" THEN SET @found = "true" /* exit the loop if found */ BREAK ENDIF NEXT @i

Salesforce AMPscript Function Reference

Regarding Populations in Contact Builder:

Populations need to be added to an Attribute Group (B) - This is necessary to define the relationship between the population and the associated data extensions and attributes.

No more than three Populations should be created (C) - Creating more than three populations can lead to performance issues and complexity in managing contacts.

When preparing data to be used in Contact Builder, the following factors should be taken into consideration:

Assigning data relationships and primary keys across all channels (A) - This ensures that data is linked properly and can be utilized across different marketing channels.

Verifying data address marketing needs (B) - Ensuring that the data aligns with the marketing goals and requirements.

Normalizing data to reduce redundancy (E) - Organizing the data to eliminate duplicate entries and improve efficiency.

A Contact can be reintroduced into the system only after the deletion is fully complete. The Contact Delete process in Salesforce Marketing Cloud is designed to ensure that all references and data associated with the contact are thoroughly removed. Reintroducing the contact before the process is fully complete would disrupt this cleanup process and potentially lead to data integrity issues.

When importing an encrypted file from the Enhanced FTP server, you need to move the file to the Safehouse first, and then decrypt it within the Safehouse.

Move to Safehouse: Use a File Transfer activity to move the encrypted file from the Enhanced FTP server to the Safehouse.

Decrypt in Safehouse: Use another File Transfer activity to decrypt the file within the Safehouse.

Salesforce File Transfer Activities

To add an image to Content Builder via the API and retrieve the image's published URL, the developer should POST to the REST API/asset/v1/content/assets and parse the FileProperties parameter (D). This method uploads the image and returns metadata, including the published URL, which can be extracted from the FileProperties.

Switching to Tenant Specific Endpoints (TSEs) provides the benefit of improved API performance (D). Tenant Specific Endpoints are designed to provide optimized performance by ensuring that API calls are routed through endpoints that are dedicated to a specific tenant, reducing latency and potential congestion issues associated with shared endpoints.

To append the subscriber's zip code to a link and ensure that the clicks are tracked, you should use the Lookup function to retrieve the zip code from the data extension and the RedirectTo function to create the link with tracking enabled.

Lookup: Retrieves the zip code from the data extension.

RedirectTo: Ensures that the link with the appended zip code is tracked.

Example:

ampscript

Copy code

%%[ SET @zipcode = Lookup("DataExtensionName", "zipcode", "SubscriberKey", _subscriberkey) SET @link = Concat(" ", @zipcode) ]%%

Salesforce AMPscript Lookup Function

Salesforce AMPscript RedirectTo Function

To retrieve multiple records associated with a particular customer from the OrderDetails data extension, the LookupRows and LookupOrderedRows functions are suitable. These functions return a rowset containing the records that match the specified criteria.

LookupRows: Retrieves a rowset of records based on specified criteria.

Example:

ampscript

Copy code

SET @rows = LookupRows('OrderDetails', 'CustomerID', @customerID)

LookupOrderedRows: Retrieves a rowset of records based on specified criteria and allows for sorting.

Example:

SET @rows = LookupOrderedRows('OrderDetails', 0, 'OrderDate DESC', 'CustomerID', @customerID)

Salesforce AMPscript LookupRows

The operational order of the Contact Delete process for Marketing Cloud is as follows:

Delete initiated - The process begins when the contact delete request is initiated.

Suppression phase - During this phase, the contacts are marked for deletion and are suppressed from further communications.

Final Deletion - The contacts are permanently deleted from the system.

A File Drop Automation should be configured to handle files that arrive at varying times and have unique filenames. This type of automation triggers when a file is dropped into a specific folder on the Enhanced FTP site, allowing the system to handle imports as soon as the file arrives.

Salesforce File Drop Automations

To ensure that contacts relate across different channels in Marketing Cloud, you need to link the unique identifier used across channels to the Contact ID in Contact Builder. This involves creating Attribute Groups and establishing the relationships between the unique identifier and the Contact ID.

Link the Numeric Field Value: By linking the numeric unique identifier to the Contact ID in Attribute Groups, you ensure that each contact is uniquely identified across channels.

Create Attribute Groups: Attribute Groups in Contact Builder allow you to map the relationships between different data sources and the Contact object, ensuring that the unique identifier is connected correctly for each channel.

Salesforce Contact Builder Documentation

In Salesforce Marketing Cloud, access tokens are valid for one hour (D). After one hour, a new access token must be obtained to continue making API calls. This ensures security and helps manage the lifespan of tokens effectively.

After using LookupRows to retrieve data when building a dynamic email, the next step before using this rowset within a FOR loop is to use RowCount to ensure the rowset contains data (D). This validation ensures that there are rows to iterate over, preventing potential errors or empty iterations in the FOR loop.

Example:

SET @rows = LookupRows("DataExtensionName", "FieldName", "Value") SET @rowCount = RowCount(@rows) IF @rowCount > 0 THEN FOR @i = 1 TO @rowCount DO SET @row = Row(@rows, @i) /* process each row */ NEXT @i ENDIF

To retrieve daily JSON data from a customer's API and write it to a data extension, the developer should use the following set of Server-Side JavaScript activities:

Platform.Function.HTTPGet(); - To make the HTTP GET request to the customer's API and retrieve the JSON data.

Platform.Function.ParseJSON(); - To parse the retrieved JSON data.

Platform.Function.UpsertData(); - To upsert the parsed data into a data extension.

Example code snippet:

var response = Platform.Function.HTTPGet(" "); var jsonData = Platform.Function.ParseJSON(response); Platform.Function.UpsertData("DataExtensionName", ["PrimaryKeyField"], jsonData);

When the subjectLine variable is declared in multiple locations throughout the email, the value used at the time of deployment will be the last value assigned to the variable. In the provided declarations, the last assignment is:

%%[ SET @subjectLine = 'Enjoy 20% off today' ]%% was declared within the Subject Line

Therefore, the subject line used at the time of deployment will be "Enjoy 20% off today" (C).

To handle unexpected errors gracefully in a custom subscription center, wrapping the code in a Server-Side JavaScript (SSJS) Try/Catch block is recommended.

Try/Catch Block: Using a Try/Catch block in SSJS allows the developer to catch and handle exceptions, providing a mechanism to manage errors without disrupting the user experience.

SSJS Example:

<script runat="server"> Platform.Load("Core", "1"); try { // Code that may throw an error } catch (e) { // Handle the error Write(Stringify(e)); } </script>

Salesforce Server-Side JavaScript (SSJS) Guide

To ensure the expiration date on a coupon is the last day of the month, the developer should find the first day of the next month and subtract one day (A). This approach guarantees that the expiration date is set to the last day of the current month.

Example AMPscript:

SET @firstDayNextMonth = DateAdd(DatePart(Now(), "MM"), 1, "M") SET @lastDayCurrentMonth = DateAdd(@firstDayNextMonth, -1, "D")

To automate the process of importing encrypted files from an external CRM, the following actions should be included:

File drop to the SFTP Import directory: Place the encrypted files in the SFTP Import directory to trigger the automation.

File transfer activity to the Safehouse for decryption: Move the encrypted files to the Safehouse for decryption, ensuring the data is securely handled.

Import definition to the necessary data extension: After decryption, import the data into the relevant Data Extension for use in marketing sends.

To reference subscriber, system, and sendable Data Extension attributes for content personalization using SSJS, the correct syntax is . This tag allows you to dynamically insert the value of an attribute into the email content.

Tag: This tag is used to insert the value of an attribute from a Data Extension or subscriber attribute into the content. The name attribute of the tag specifies which attribute's value should be used.

%%[ var @firstName set @firstName = AttributeValue("FirstName") ]%% Hello, !

Salesforce SSJS Guide

This syntax ensures that the correct personalization attributes are pulled into the email, enabling dynamic and personalized content based on subscriber data.

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.

To retrieve the status of an asynchronous SOAP API call to the TriggerSend object, you should use the ResultItem object along with the RequestID attribute.

ResultItem Object: This object provides detailed information about the status of each individual request made within the API call.

RequestID Attribute: This unique identifier is used to track and retrieve the status of the specific API request.

Salesforce SOAP API Developer Guide

The Contact Delete process can be slow for a large number of contacts. To expedite this process, the best approach is to stop the current delete process and delete smaller groups of contacts. This allows the system to handle smaller chunks of data more efficiently.

Stop Current Process: Stopping the current large delete process helps avoid system overload and potential timeouts.

Delete in Smaller Groups: By segmenting the contacts into smaller groups and deleting them in batches, the process becomes more manageable and faster.

Salesforce Contact Deletion Best Practices

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.

The JobID parameter is required for the LogUnsubEvent request to be tied to the appropriate send. The JobID uniquely identifies the email job that was sent, allowing the system to accurately log the unsubscribe event for that specific send.

JobID: This parameter ensures that the unsubscribe event is correctly associated with the email send job.

Salesforce LogUnsubEvent Documentation

When using Server-Side JavaScript (SSJS) in Salesforce Marketing Cloud, the developer can leverage the following features:

Wrapping of AMPscript in SSJS code (A) - SSJS can include AMPscript within its code, allowing for dynamic content generation and manipulation.

Include Try/Catch blocks within the code (D) - SSJS supports the use of Try/Catch blocks to handle errors and exceptions in the script, providing better control over error management.

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 optimize a SQL Query Activity in Automation Studio that is experiencing timeouts, the developer should use intermediate tables to break queries into smaller parts (B). This approach helps in managing complex queries by breaking them down into smaller, more manageable steps, thus reducing the likelihood of timeouts.

To validate that a parent-level data extension can be accessed by a child business unit, the developer should ensure that the data extension is in the Shared Data Extensions folder and the query includes the ENT. prefix (A). This setup allows shared data extensions to be accessible across different business units.

To add new customers to a cross-channel welcome campaign when they register on the company website, the Journey Builder API (D) should be used. This API allows you to programmatically inject contacts into a journey, triggering personalized marketing interactions across multiple channels.

The Output function in AMPscript is used to include the result of interpreted code within a code block in the rendered content. This function ensures that the evaluated result of the code is included directly where the Output function is called.

Example:

ampscript

Copy code

%%[ SET @message = "Hello, World!" ]%% %%=Output(@message)=%%

Salesforce AMPscript Output Function

In AMPscript, the valid syntax for comments is /* comment */. This allows you to add comments within your AMPscript code for documentation or clarification purposes.

Salesforce AMPscript Syntax Guide

The Describe method in the SOAP API provides metadata about the objects available in the system, including Profile and Preference Attributes. This method can be used to dynamically retrieve and display these attributes in a custom profile center.

Describe Method: This method returns the schema of the objects, including fields and their properties, which can be used to dynamically generate forms and interfaces.

Salesforce SOAP API Describe Method

To build an audience by identifying subscribers who opened a specific email, the developer should use the following query:

SELECT SubscriberKey FROM _Open WHERE JobID = '1234'

This query selects the SubscriberKey from the _Open data view where the JobID matches the specific email send.

To aggregate monthly energy usage data stored in variables for each month, you should use the ADD function in AMPscript to sum up the values. The ADD function can be nested to handle multiple values.

AMPscript Example:

%%[ SET @total = ADD(@jan, ADD(@feb, ADD(@mar, @apr))) ]%%
