CompTIA Network+ (N10-009) — Question 4

Which of the following technologies are X.509 certificates most commonly associated with?

Answer options

• A. PKI
• B. VLAN tagging
• C. LDAP
• D. MFA

Correct answer: A

Explanation

X.509 certificates are primarily used in Public Key Infrastructure (PKI) to manage digital certificates for secure communications. The other options, such as VLAN tagging, LDAP, and MFA, do not directly relate to the use of X.509 certificates in the same way that PKI does.
