What must be configured in the email client for PKI encryption to work properly?

• A. Email address verification
• B. Certificate revocation checking
• C. Email server synchronization
• D. User account status

Answer: (B)

For PKI (Public Key Infrastructure) encryption to function effectively in an email client, it is essential to configure certificate revocation checking. When encryption is implemented using digital certificates, it ensures the authenticity and integrity of the exchange. However, an important aspect of maintaining security is ensuring that the certificates in use are still valid and have not been revoked by a certificate authority (CA). Certificate revocation checking involves verifying that the digital certificate isn’t listed on a Certificate Revocation List (CRL) or hasn’t been reported as compromised. If a certificate is revoked, any data encrypted with that certificate could be at risk, as the recipient cannot safely use the corresponding private key. Thus, having this configuration in place safeguards against unauthorized access and potential security breaches, supporting the overall trust model that PKI relies upon. Options such as email address verification, email server synchronization, and user account status may be important for other elements of email security and functionality but do not directly pertain to the process of ensuring that PKI encryption remains secure and reliable.
