Which feature allows tag deployment without editing site code directly?

• A. A web-based interface to manage tags
• B. A built-in web server
• C. A browser plugin that edits HTML directly
• D. A data warehouse

Answer: (A)

Using a web-based interface to manage tags is what enables deploying analytics and marketing tags without touching the site's code each time. A tag management system sits on top of your pages with a single container snippet placed once. Through the online interface, you configure, add, move, or remove tags (like analytics, ads, or tracking pixels) and set when they fire. When you publish changes, the system updates how tags load on the site, so marketing teams can deploy and adjust tracking without editing the site's HTML or JavaScript directly. This streamlines testing, reduces the risk of breaking the site, and centralizes tag governance.

The other options don’t fit this purpose: a built-in web server is not about tag deployment; a browser plugin that edits HTML directly still requires modifying the page or injecting edits on the fly and isn’t how scalable tag management is done; a data warehouse is for storing and analyzing data, not for deploying or managing tags on a live site.
