Explanation
To test emails before sending them, the marketing team can use the test list feature in the testing tab of the email flow. This feature allows them to send test emails to a list of approved users who can view the links and variable tags as prospects will see them. The test list can be created in Marketing Cloud Account Engagement and added to the testing tab of the email flow. References: [Marketing Cloud Account Engagement Test List]

Explanation
Form handlers are the best option if you want to integrate with a third-party system, such as a payment gateway, a survey tool, or a webinar platform. Form handlers allow you to post data to more than one location, so you can send the prospect information to Marketing Cloud Account Engagement and to the external system at the same time1. You can also use form handlers to connect Marketing Cloud Account Engagement to your existing forms on your website or other platforms

The feature that the Marketing Cloud Account Engagement administrator should use to gather a prospect's company name and job title, but only once they have captured the prospect's first name, last name, and email address in a previous form submission, is progressive profiling. Progressive profiling is a feature that allows the administrator to display different fields on a form based on the information that the prospect has already provided. This way, the administrator can avoid asking the same questions repeatedly and collect more information gradually. Progressive profiling can be enabled on a form by selecting the option "Always display even if previously completed" for the fields that are required, such as first name, last name, and email address, and selecting the option "Only display if progressive profiling is enabled and the field is blank" for the fields that are optional, such as company name and job title. This way, the form will only show the optional fields once the required fields are filled out. Always display even if previously completed, reCaptcha, and dependent fields are not features that can achieve the same goal as progressive profiling. Always display even if previously completed is an option that can be used to enable progressive profiling, but it is not a feature by itself. reCaptcha is a feature that can be used to prevent spam submissions on a form, but it does not affect the fields that are displayed on the form. Dependent fields are fields that are displayed or hidden based on the value of another field, but they do not depend on whether the prospect has already provided the information or not.

The automatic workflow that can be created to prevent the unassigned prospects from getting assigned is to create an automation rule based on the prospects' time to adjust their score to 0 if they haven't been active in 60 days. An automation rule is a rule that runs continuously in the background and matches prospects based on the criteria you set. You can use an automation rule to perform actions on the matched prospects, such as adding them to a list, assigning them to a user, or changing their field values. However, an automation rule can only match a prospect once in its lifetime, even if the prospect meets the criteria again later. This prevents duplicate or conflicting actions from being applied to the same prospect1. Therefore, an automation rule is ideal for creating a workflow that resets the score of the unassigned prospects who have been inactive for 60 days, and prevents them from getting assigned by another automation rule that assigns prospects based on their score. To create an automation rule, you need to specify the criteria and the actions that you want to execute. For example, you can create an automation rule that matches prospects who have not been assigned to a user, have not had any activity in the last 60 days, and have a score greater than 0, and then use the action Adjust Score to set their score to 0.

Explanation
If a Marketing Cloud Account Engagement administrator wants to keep the first value submitted in a field even if the prospect completes additional forms with different values for that field, they should enable the form field option "Maintain the initial value upon subsequent form submissions" (A). This option prevents the field from being overwritten by later submissions. The option "Always display even if previously completed" (B) does not affect the field value, but only the field visibility on the form. The option "Kiosk/Data Entry Mode:
Do not cookie browser as submitted prospect" does not affect the field value, but only the prospect tracking method. The option "Include "Not you?" link to allow visitors to reset the form" (D) does not affect the field value, but only the form reset functionality. References: Create a Form
