Goals are the Journey Builder component that addresses the two requirements of this campaign. Goals allow marketers to define a desired outcome for each journey, such as making a purchase at the NTO outlet, and track how many contacts achieve it. Goals also allow marketers to exit contacts from the journey once they achieve the goal, which means they will stop receiving emails from the campaign. Decision Splits are used to branch contacts into different paths based on criteria, but not to exit them from the journey or track their outcomes. Exits are used to remove contacts from the journey based on criteria, but not to track their outcomes.

The originally approved version of the email will be sent if the approval is withdrawn after scheduling the send. The withdrawal of approval does not affect the scheduled send, unless the marketer cancels or reschedules it manually. [Source: Trailhead]

Creating from template and choosing triggered send template is required when creating a data extension for a triggered send. This template includes the required fields for a triggered send, such as Subscriber Key, Email Address, and Triggered Send External Key. Selecting the 'Use for triggered send' checkbox is not required, but optional. Including the Subscriber Key and Email Address field as the primary key is not correct, because only one field can be the primary key, and it should be Subscriber Key.

The tag that NTO should add to the HTML <a> element to differentiate the links is linkname1. Linkname is an attribute that allows NTO to assign a custom name to each link in their email, which can help them track and measure the performance of each link type2. By using linkname, NTO can see how many clicks each image, text, or URL link received in their email reports3. For example, NTO can use linkname like this:
<a href="https://www.nto.com" linkname="logo"> <img src="logo.png" alt="NTO logo"> </a> <a href="https://www.nto.com" linkname="text"> Click here to visit our website </a> <a href="https://www.nto.com" linkname="url"> https://www.nto.com </a> Conversion is not the correct answer, as it does not help differentiate the links. Conversion is an attribute that allows NTO to track and measure the revenue generated by each link in their email4. By using conversion, NTO can see how much sales each link contributed to their email campaigns5. However, conversion does not affect the name or appearance of the links.
Alias is also not the correct answer, as it does not help differentiate the links. Alias is an attribute that allows NTO to assign a friendly name to each link in their email, which can help them improve their email deliverability and reputation. By using alias, NTO can avoid using long or suspicious-looking URLs that may trigger spam filters or deter subscribers from clicking. However, alias does not affect the tracking or reporting of the links.
