In a typical SSL setup involving a trusted party and trusting party, what consideration should...

 D is correct because using aself-signed certificate leads to higher maintenance for the trusting party, which is the client or browser that connects to the server. The trusting party needs to add the self-signed certificate to their truststore, which is a repository of trusted certificates, in order to establish a secure connection with the server. Otherwise, the trusting party will see a warning message or an error when accessing the server.

A is incorrect because using a self-signed certificate leads to higher maintenance for the trusted party, not lower. The trusted party needs to maintain multiple self-signed certificates from different servers in their truststore.

B is incorrect because using a self-signed certificate does not make the trusted party act as the trusted CA (Certificate Authority). The trusted CA is the entity that issues and validates certificates for servers. The trusted party only needs to trust the CA’s root certificate, which is usually pre-installed in their truststore.

C is incorrect because using a self-signed certificate leads to higher maintenance for the trusting party, not lower. The trusting party still needs to maintain a trusted CA cert in their truststore, which is the self-signed certificate itself.
