Correct answer: Write and edit code in the GTM interface, Pass data into third-party applications, Use data to fire tags.
Why this is the answer
The data layer is a JavaScript object that temporarily holds data you want to pass from your website to Tag Manager. You can write and edit code within the GTM interface to interact with this data layer, defining what information is pushed to it and how it's used. This data can then be used to trigger tags (e.g., fire a conversion tag when a specific product ID is present in the data layer) and to populate tags with dynamic values. By making data available in the data layer, you can easily pass it to various third-party applications integrated through Tag Manager, such as Google Analytics, Google Ads, or other marketing platforms. The data layer itself does not automatically encrypt data; data security is handled at other layers of your website and application architecture.
