Which Redirect_Act action is used in the example to redirect traffic?

• A. Redirect_Act respond with "DIAMETER.NEW_REDIRECT("aaa://host.example.com")"
• B. Redirect_Act "redirect to host.example.com"
• C. Redirect_Act "http_redirect"
• D. Redirect_Act "RESPOND"

Answer: (A)

Redirect_Act is used to tell the appliance how to redirect traffic, and in this case the redirect is protocol-specific. The example shows sending a respond action that carries a Diameter redirect instruction, DIAMETER.NEW_REDIRECT("aaa://host.example.com"). This directly instructs the client to contact the new AAA host using the Diameter protocol, with the destination clearly defined by the URI. The respond part ensures the redirect is communicated back to the client as a redirect decision, not a generic rewrite or a different protocol redirect.

Other forms don’t fit because they don’t provide the protocol-specific redirect instruction needed for Diameter traffic. A plain redirect text or an HTTP-style redirect isn’t appropriate for Diameter/AAA traffic, and a generic RESPOND without the proper DIAMETER redirect directive wouldn’t steer the client to the new destination.
