XML Tags and Delimiters in Prompts Quiz

Answers and explanations appear as you take the quiz.

1. What is the main reason delimiters make prompts more reliable?
   • They make the prompt shorter
   • The model can tell where each part of the prompt starts and ends
   • They switch the model into a special mode
   • They reduce the price per token
2. Do you have to use specific official tag names like <document>?
   • Yes, only names from the provider's official list work
   • Yes, and tags must be valid strict XML
   • No, there is no official list, but you should use names consistently and refer to them
   • No, and tag names should change on every request
3. Are XML tags a reliable security boundary against prompt injection?
   • No, text inside tags can still contain injection attempts that may succeed
   • Yes, models ignore everything inside tags
   • Yes, but only if tags are nested
   • Only with the <secure> tag
4. Why ask the model to put its final result inside <answer> tags?
   • It makes the answer more accurate by default
   • It lowers the cost of output tokens
   • It hides the answer from the user
   • It gives your code a reliable place to extract the result
5. For prompts with long documents, where has Anthropic suggested placing the question?
   • Before the documents
   • At the end, after the documents
   • Only in the system prompt
   • Split across several messages
6. What should you do if user-supplied text contains your own closing tag, such as </document>?
   • Leave it, since models ignore it
   • Delete the entire user input
   • Escape or remove it so the input cannot break out of its section
   • Add more opening tags
7. Which delimiters does OpenAI's prompting guidance suggest, according to the guide?
   • Triple quotes, Markdown headings or XML
   • Only emoji markers
   • Only JSON
   • Line numbers
8. How do tags express hierarchy, such as several documents that each have a source?
   • By using capital letters
   • By numbering each line
   • By writing everything on one line
   • By nesting, for example <document> elements inside <documents>
