10.2) Why was the project deployed to wtpwebapps folder?
Because, that is the folder specified under the Server Settings in Eclipse.
wtpwebapps directory is an eclipse-specific folder created when you run a dynamic web project on Tomcat within eclipse.
webapps directory is within the Tomcat home and it's where you copy over your WAR files manually.
