What does each network error point to?

QuizMediumAsked in: Amazon, Microsoft, Netskope

Which error-to-cause pairs are correct? Choose all that apply.

  • "Could not resolve host": DNS could not turn the name into an address (typo, wrong environment name, DNS problem)
  • "Connection refused": the host answered, but nothing is listening on that port
  • "Certificate has expired" or "unable to verify certificate": a TLS problem with the server certificate or its trust chain (the chain of certificates that proves the server is real)
  • "Connection refused" means the password was wrong
