LFCS Question #205: Real Exam Question with Answer & Explanation

Question

An administrator has just configured an OpenVPN client. Upon starting the service, the following message is displayed: TLS Error: TLS key negotiation failed to occur within 60 seconds Which of the following statements is true?

Options

• AThe client was unable to establish a network connection with the server.
• BThe client was able to establish a network connection with the server, however TLS key negotiation
• CThe client was able to establish a network connection with the server, however TLS and SSL security
• DThe client was able to establish a network connection with the server, however TLS key negotiation

Explanation

The question describes an OpenVPN client displaying a TLS key negotiation failure error and asks for the true statement regarding the underlying issue.

Common mistakes.

• B. If the client was able to establish a network connection, the error would likely be more specific to TLS handshake issues (e.g., certificate mismatch, cipher negotiation failure), not a complete timeout on negotiation.
• C. Stating that a network connection was established contradicts the typical interpretation of a TLS negotiation timeout, which implies a lack of initial communication or severe blockage.
• D. This statement is technically incomplete and implies a network connection was made, which is unlikely given a negotiation timeout; if connected, negotiation would occur, and a different error would typically arise.
