Creates a GRE tunnel over an IP network to connect the network analyzer to the network device.

• A. Remote Traffic Mirroring
• B. Local Traffic Mirroring
• C. SPAN or Mirrored Port
• D. Traffic Mirroring

Answer: (A)

Remote traffic mirroring is about sending a copy of traffic from a network device to a monitoring tool that's elsewhere, by tunneling the mirrored packets over an IP network (often using GRE). The scenario describes exactly that: establishing a GRE tunnel over an IP network to connect the network analyzer to the device, so the analyzer can observe the traffic remotely. Local mirroring, SPAN, or a generic traffic mirroring term would imply mirroring stays on the same device or within the local switch domain and wouldn’t involve forwarding mirrored packets across an IP network to a remote analyzer.
