Explanation
The answer that correctly describes what will happen to the prospects who landed on the End step more than 90 days ago and previously reached the 5 total entries limit is that prospects will re-enter the program immediately. A repeating engagement program is a type of program that allows prospects to re-enter the program after a certain period of time, such as 90 days, and up to a certain number of times, such as 5. If a user changes the total entries limit to a higher number, such as 10, the prospects who have already reached the previous limit, but are eligible to re-enter based on the time period, will re-enter the program as soon as the user restarts the program. Prospects will not re-enter the program after waiting another 90 days, remain ineligible to re-enter the program, or not re-enter the program until manually approved, as these are not the effects of changing the total entries limit2.

According to the Salesforce documentation, the correct steps to access a Prospect Record are: B) Mouseover Prospects, C) Click Prospect List, and A) Select Prospect. A Prospect Record is a feature that shows the detailed information and activity history of a prospect in Marketing Cloud Account Engagement. A Prospect Record can be accessed from the Prospects tab in Marketing Cloud Account Engagement, and it can show different sections of information for the prospect, such as details, insights, activities, or custom fields. To access a Prospect Record, the user needs to follow these steps:
* Mouseover Prospects: The user needs to move the cursor over the Prospects tab in the navigation bar in Marketing Cloud Account Engagement. This will open a drop-down menu with different options, such as Prospect List, Add Prospect, or Import Prospects.
* Click Prospect List: The user needs to click on the Prospect List option in the drop-down menu. This will open the Prospect List page, which shows a list of prospects in Marketing Cloud Account Engagement. The user can customize, sort, filter, search, or export the Prospect List, and they can also perform different actions on the prospects, such as assign, delete, or edit.
* Select Prospect: The user needs to select the prospect that they want to access from the Prospect List.
This will open the Prospect Record page, which shows the detailed information and activity history of the prospect. The user can view, edit, or update the Prospect Record, and they can also perform different actions on the prospect, such as sending an email, adding to a list, or changing the score or grade.

According to the Salesforce documentation, the two Marketing Cloud Account Engagement form actions that would accomplish enabling bot protection on their forms are honeypot technique and reCaptcha. Bot protection is a feature that helps prevent automated bots from submitting forms and creating fake prospects.
Honeypot technique is a method that uses a hidden field in the form that is not visible to human users, but can be detected by bots. If the hidden field is filled out, the form submission is rejected as a bot submission.
reCaptcha is a service that uses a challenge-response test to verify that the form submitter is a human and not a bot. The user can enable either or both of these options in the form settings to add bot protection to their forms. Enabling HTTPS, or Hypertext Transfer Protocol Secure, is a method that encrypts the communication between the user's browser and the web server, but it does not prevent bots from submitting forms. Dependent fields are fields that are displayed or hidden based on the value of another field, but they do not prevent bots from submitting forms either. References: Salesforce documentation

Explanation
To post a form directly to a third-party platform as well as Marketing Cloud Account Engagement upon submission, LenoxSoft should use the form handler tool in Marketing Cloud Account Engagement. This tool allows them to use their own forms while still sending the data to Marketing Cloud Account Engagement.
They can specify the third-party platform's URL as the post URL in the form handler settings and map the form fields to Marketing Cloud Account Engagement fields. References: [Marketing Cloud Account Engagement Form Handler]

Explanation
According to the [Salesforce documentation], the recommended Marketing Cloud Account Engagement asset to use for progressive profiling is a Marketing Cloud Account Engagement form. A Marketing Cloud Account Engagement form is a web form that can be used to collect information from prospects and store it in Marketing Cloud Account Engagement. A Marketing Cloud Account Engagement form can be configured to use progressive profiling, which is a feature that allows the form to display different fields based on the information that is already known about the prospect. This way, the form can collect more information over time, without asking the same questions repeatedly or overwhelming the prospect with too many fields at once. A Marketing Cloud Account Engagement landing page without a form, a Marketing Cloud Account Engagement form handler, or a third party form are not recommended for progressive profiling, as they do not have the same functionality and flexibility as a Marketing Cloud Account Engagement form.
