Explanation:
Users can obtain certificates with various levels of assurance.
Level 1/Class 1 certificates verify electronic mail addresses. This is done through the use of a personal
information number that a user would supply when asked to register. This level of certificate may also provide a
name as well as an electronic mail address; however, it may or may not be a genuine name (i.e., it could be an
alias). This proves that a human being will reply back if you send an email to that name or email address.
Class 2/Level 2 verify a user’s name, address, social security number, and other information against a
credit bureau database.
Class 3/Level 3 certificates are available to companies. This level of certificate provides photo identification to
accompany the other items of information provided by a level 2 certificate.
Incorrect Answers:

social security number, and other information against a credit bureau database.
C: Level 3/Class 3 certificates provide photo identification to accompany the other items of information provided
by a level 2 certificate. They do not verify a user’s name, address, social security number, and other information
against a credit bureau database.
D: Level 4/Class 4 certificates do not verify a user’s name, address, social security number, and other
information against a credit bureau database.
