What is the cause of the issue?

Show Answer
Correct Answer: AC

The issue is that the client and server cannot agree on a common cipher. The exhibit shows that during the SSL handshake process, the server selected the cipher suite 'SSL_RSA_WITH_RC4_128_SHA', which is present in the client's list of supported cipher suites. This indicates that the SSL/TLS handshake successfully negotiated a common cipher suite. Therefore, the client authentication and pool configuration are not the issues. Since the client and server selected a compatible cipher suite, the problem is unlikely to be related to the common cipher agreement.

A - Correct The server then sends a "CertificateRequest", indicating that it expects the client to provide a certificate for mutual authentication, where both the server and the client need to present valid certificates. The client likely doesn't have a certificate to provide, leading to the authentication failure.
