1. How does Sitecore define a type of item (the data schema)?
Sitecore defines data schemas with templates. These define fields, field type, and field sections that describe a type of item. The use of items – and thereby the template on which they are based – helps determines the governance model around them.
2. Why do we set icons on our template?
Giving your templates an icon ensures that you easily differentiate between different types of items.
3. What is the default base template for all templates?
Standard template under Templates/System/Templates/Standard template
4. How do we make our changes appear on the live website?
Publish Site. When you are ready to publish your website, you can run the publishing wizard, which guides you through the steps of publishing in Sitecore. You can run the publishing wizard from the Content Editor and the Sitecore Desktop.
5. What is Experience Management (xManagement)?
Experience Management (CMS-only mode) allows you to run Sitecore XP without the Experience Database (xDB) enabled or purchasing xDB licenses. With Experience Management, you can use Sitecore to create, manage, and publish content to your websites.
6. What is the preferred way to modify the web.config?
Use Notepad? For overwriting the Sitecore settings, use patch and set in your own .config files.
