Salesforce Updated Marketing-Cloud-Email-Specialist Exam Questions and Answers by cadi

Ensuring preferred channel is available in subscriber data is the correct answer. This option allows you to use dynamic content or decision splits in Journey Builder to honor the opt-in communication method of your subscribers. For example, you can use an attribute or a data extension field that indicates whether a subscriber opted-in via email or SMS, and then use that information to send them a welcome message through their preferred channel. Sending both email and SMS to ensure subscribers get NTO’s messages is not a good option, as it may annoy or spam your subscribers who only opted-in for one channel. Creating one entry source for each messaging channel is not necessary, as you can use one entry source that supports both channels, such as API event or CloudPages form submit. You can learn more about this in the [Journey Builder Basics] module on Trailhead.

The Update Contact Activity is used to update the contact data in Journey Builder, not to make decisions on it. To make decisions on the status data, it should be connected to the contact in an attribute group and used in a decision-split activity on the journey canvas. [Source: Trailhead]

 Einstein Content Selection is the feature that NTO should use to build a welcome journey for new customers with dynamic content in each email. Einstein Content Selection allows marketers to create personalized content for each customer based on their behavior and preferences, and also include assets that are automatically optimized based on real-time performance data. Einstein Content Selection can be used with Content Builder to create dynamic content blocks that can be inserted into emails and journeys. 

List Detective is the correct answer. List Detective is a feature that automatically filters out invalid or problematic email addresses from your sends, such as those with typos, syntax errors, or unsupported domains. List Detective helps improve your deliverability and reputation by preventing bounces and spam complaints from bad email addresses. Bounce Mail Management is a feature that tracks and manages bounced emails based on different bounce categories and thresholds. Auto-Suppression Lists are lists of subscribers who should not receive certain types of emails, such as promotional or transactional emails. You can learn more about these features in the [Email Deliverability] module on Trailhead.
