In Huawei's SD-WAN solution, which of the following technologies can "enable branch equipment to automatically adapt to the new link without needing to re-adapt after changing network operators"?

Question

Options

• AManually reconfigure the link parameters of the branch devices.
• BSD-WAN Link Adaptive Technology (Automatically identifies new links and loads preset policies)
• CAfter changing carriers, delete the original configuration and start a new game.
• DOnly supports fixed carriers; link switching is not supported.

• A
  2% (1)
• B
  84% (38)
• C
  9% (4)
• D
  4% (2)

Explanation

SD-WAN Link Adaptive Technology (B) is correct because it is specifically designed to automatically detect and adapt to new network links when a carrier changes - no manual intervention required, as the system identifies the new link and applies pre-configured policies automatically.

Why the distractors fail:

• A defeats the entire purpose of SD-WAN automation; manual reconfiguration is the old-school approach SD-WAN replaces.
• C is operationally disruptive and describes zero-automation behavior - the opposite of SD-WAN's value proposition.
• D contradicts SD-WAN's core design goal of carrier-agnostic, multi-link flexibility.

Memory tip: Think of SD-WAN Link Adaptive as a smartphone that automatically reconnects to Wi-Fi without you re-entering the password - it "remembers the policy" and applies it the moment it sees a new link.
