Chapter 15 lists four questions you should ask before posting an electronic résumé on an Internet job board. One question is "Who has access to your résumé?" What is one of the other questions?

Without knowing the specific context or source of the chapter you're referring to, I can't provide the exact questions listed in Chapter 15. However, I can offer some common questions that are generally recommended to consider before posting an electronic résumé on an Internet job board:

1. Who has access to your résumé? (As you've mentioned)
2. How will your privacy be protected?
3. What job search services does the site provide?
4. How long will your résumé remain active on the site?

These questions are important to consider to ensure that your personal information is secure, to understand the scope of the job board's services, and to manage your job search effectively. Always read the privacy policy and terms of use of any job board before uploading your résumé.
