Question

Quizplus · Accepted Answer

SSL authentication can support three key sizes: 40 bit, 56 bit, and 128 bit. While 40 bit and 56 bit keys are no longer considered secure and are vulnerable to attacks, 128 bit keys provide a much stronger level of security and are currently recommended for use with SSL authentication. Choosing option C allows for the use of both obsolete and insecure options as well as the recommended one, but it ultimately allows for the strongest level of security.
