What is the default configuration in ZTunnel 2.0 for secure communication?

• A. Default to TLS with no fallback option
• B. Default to DTLS with the ability to fall back to TLS
• C. Always use HTTP regardless of security
• D. Configuration must be set manually by the user

Answer: (B)

The choice indicating that ZTunnel 2.0 defaults to DTLS with the ability to fall back to TLS is accurate because it highlights the inherent design of ZTunnel to prioritize performance while maintaining a secure connection. DTLS (Datagram Transport Layer Security) is used because it offers low-latency communication, which is crucial for applications requiring quick response times. However, in situations where DTLS is not supported or experiences issues, the protocol's capability to fall back to TLS (Transport Layer Security) ensures that secure communication remains intact. This design allows Zscaler to achieve a balance between speed and security, making sure that the user experience is not compromised while still adhering to necessary security protocols. All of this underlines the robustness and flexibility of ZTunnel 2.0 in maintaining secure connections across different network environments.
