Pass the Salesforce Developers Marketing-Cloud-Developer Questions and answers with CertsForce

The error stating that the application cannot insert a duplicate value for the primary key in the data extension occurs because the InsertDE function cannot be used at send time. The InsertDE function is designed to insert records into a data extension, but it cannot handle the transactional nature of email sends where records might be added simultaneously.

To secure a CloudPage and its elements (such as images) using SSL, a single SSL certificate can be used if both the CloudPage and the images are hosted under the same domain. This SSL certificate ensures that all content served from that domain is encrypted and secure.

Profile attributes like AGE in Profile Manager are not directly accessible via the _Subscribers data view or _EnterpriseAttribute data view. To retrieve subscribers over 30 years of age, creating a filtered Group based on the AGE attribute is the most effective method.

A "401 Unauthorized" error typically indicates an issue with authentication or permissions. Since the Client ID and Client Secret have been successfully used in other REST calls, the most likely cause is insufficient permissions for sending emails.

Check Send Permissions: Ensure that the appropriate permissions for sending emails have been granted to the Client ID and Client Secret in the Installed Packages. Without these permissions, the API call will fail with a 401 error.

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.

Regarding the Marketing Cloud SOAP API, the following statements are true:

Most SOAP calls can be synchronous or asynchronous (B) - This means that API calls can either wait for the operation to complete (synchronous) or proceed with other tasks while waiting for the response (asynchronous).

Uses XML in request and response body (C) - The SOAP API utilizes XML for both requests and responses, providing a standardized format for data interchange.

When using the REST API to send emails to customers after a purchase, the developer should make a token API call and re-use the token until the token expires (D). This approach optimizes API usage by reducing the number of token requests, ensuring that the token is reused until it naturally expires, after which a new token can be requested.

To execute daily reports on all subscriber activity without impacting send performance, the best practice is to copy new Send Log records to an Archive data extension, then run reports from the Archive data extension (C). This approach ensures that the reporting activity does not interfere with the performance of ongoing send operations.

Transparent Data Encryption (TDE) is designed to protect data at rest by encrypting the underlying storage of the database. This method ensures that data is encrypted on disk to prevent physical data theft while allowing it to remain accessible to authorized users within the system.
