Which statement describes the use of certificate classes in the PKI?

  • Email security is provided by the vendor, not by a certificate.
  • A vendor must issue only one class of certificates when acting as a CA.
  • A class 5 certificate is more trustworthy than a class 4 certificate.
  • The lower the class number, the more trusted the certificate.

Explanation: The higher the certificate number, the more trustworthy the certificate. Class 1 certificates are for individuals, with a focus on email verification. An enterprise can act as its own CA and implement PKI for internal use. In that situation, the vendor can issue certificates as needed for various purposes.​
