Which tunneling method connects the network analyzer to the network device over an IP network?

The correct answer is based on the ability of Remote Traffic Mirroring to send a copy of network traffic from one device to another device over an IP network. This method allows a network analyzer, which could be located on a different network segment, to receive and analyze the traffic originating from a source network device.

Remote Traffic Mirroring operates by forwarding packet data from a source port on a network switch to a remote collector or analyzer, effectively enabling monitoring and analysis of traffic that may not be accessible locally. This capability is particularly useful in distributed environments where network traffic needs to be monitored for performance or security reasons without being limited by physical proximity to the observed traffic.

The other options serve different purposes: Local Traffic Mirroring typically captures traffic for analysis on the same local network segment, while SPAN (Switched Port Analyzer) or Mirrored Port refers to the practice of mirroring traffic within a local switch but without the capacity to forward this data over a broader IP network like Remote Traffic Mirroring does. Domain Name System (DNS) is unrelated, as it is a protocol for resolving domain names rather than a method for traffic analysis or tunneling.
