To monitor whether all records were added to the target data structure each day, NTO should use the Notification Settings within the Import File Activity. The Notification Settings allow NTO to specify an email address or a data extension to receive notifications about the status and results of the import. The notifications include information such as the number of records processed, added, updated, skipped, or failed. This way, NTO can track and verify the import process and identify any issues or errors. The other options are incorrect because:

• External Key within the Import File Activity. The External Key is a unique identifier for the Import File Activity that can be used for API calls or SQL queries. However, it does not provide any information about the status and results of the import.
• Run Completion within the File Drop Automation. The Run Completion is a summary of the execution of the File Drop Automation that shows the start time, end time, duration, and status. However, it does not provide any information about the status and results of the import.
• Runtime Error within the File Drop Automation. The Runtime Error is a message that indicates an error occurred during the execution of the File Drop Automation that prevented it from completing successfully. However, it does not provide any information about the status and results of the import.

Email Form Content Block is the feature that could be used to solicit website feedback without navigating away from the email. Email Form Content Block is a type of content block that allows marketers to create and insert forms within emails, such as surveys, polls, or feedback requests. Email Form Content Block can be customized with different fields, labels, buttons, and actions. Email Form Content Block can capture subscriber responses within the email without requiring them to visit a landing page or a website

To record send log data, the send logging feature must be enabled for the send. This can be done by selecting the send log data extension in the Delivery Options tab of the email send wizard.

 To resolve the issue of not being able to see the audience file in the data extension when scheduling the send, the admin should confirm that the data extension is marked as Sendable. A sendable data extension is one that has an email address field and a subscriber key field that can be used for sending emails. If the data extension is not marked as sendable, it will not appear as an option when selecting an audience for an email send. The other options are incorrect because:

• The data extension contains a Salesforce ID. This is not a requirement for sending emails from a data extension. A Salesforce ID is only needed if NTO wants to use Marketing Cloud Connect to sync data between Marketing Cloud and Salesforce CRM.
• The Data extension is marked as Sendable and Testable. This is not a valid option for marking a data extension. A data extension can only be marked as sendable or non-sendable; there is no testable option.
• The data extension is linked using the Contact Key. This is not a requirement for sending emails from a data extension. The Contact Key is only needed if NTO wants to use Contact Builder to link data across different sources and channels.

To view the test emails that have been sent from Email Studio, the Marketing Cloud admin can go to My Tracking > Test Send Emails3. This page shows the details of each test email, such as the subject line, sender name, recipient email, and status3. The other options are not relevant for viewing test emails.

Separating regions into business units and applying subscriber filters is the best way to ensure distinct data integrity across the regions. Subscriber filters allow you to control which subscribers are visible in each business unit based on criteria such as location, language, or preference.

Removing Marketing Cloud Viewer role from the user would allow the analyst to import contact lists. The Marketing Cloud Viewer role is a read-only role that prevents users from performing any actions on data or content. The Marketing Cloud Channel Manager role already grants the user permission to import contact lists. The other options would not solve the problem or are unnecessary.
