Certificates that are not recognized as trustworthy?

Certificates that are not recognized as trustworthy?

• A. Privacy considerations
• B. Software sources
• C. Valid
• D. Invalid

Answer: (D)

Not recognized as trustworthy means the certificate cannot be used to securely establish a connection. In TLS/PKI, trust comes from a certificate chain that leads to a trusted root authority. If a certificate is expired, revoked, not issued by a trusted authority, has a broken chain, or its hostname doesn’t match, it cannot be validated and is treated as not trustworthy. That state is described as invalid for secure communications, so the correct choice is Invalid. Privacy considerations and where software comes from aren’t about whether a certificate is trusted, and being valid would imply it is trusted, which isn’t the case here.
