Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 363

What is the first step for setting up traffic flows when enabling TLS Proxy in SD-WAN for security?

Answer options

• A. The sender authenticates the devices and individual users, and the receiver verifies the signature by decrypting the message with the public key of the sender.
• B. Certificate authorities in TLS Proxy issue certificates for authentication to all entitles such as hosts, network devices, or users.
• C. When decryption policy is enabled for the flow, a client hello packet is received by Unified Threat Defense to define the decryption action.
• D. The TCP connection is established between the client and the proxy, and between the proxy and the server.

Correct answer: D

Explanation

The correct answer is D because establishing a TCP connection between the client and the proxy, as well as between the proxy and the server, is essential for facilitating secure communication. Other options describe processes that occur after the initial connection is established, like authentication or decryption, which are not the first steps in setting up traffic flows.
