What is true about flow mirroring?

Flow mirroring is a technique used in networking and monitoring that involves copying network packets to another destination for analysis and observation. The statement that it is divided into local flow mirroring and remote flow mirroring accurately reflects how flow mirroring is implemented.

Local flow mirroring refers to the practice where packet copies are sent to a destination device located within the same local network. This is often utilized for on-the-spot analysis or monitoring by tools that are co-located in the same environment, allowing immediate access to the data.

Remote flow mirroring, on the other hand, allows the mirrored packets to be sent to a different geographic location, often across WAN connections. This is particularly valuable for centralized monitoring and analysis systems that may be deployed far from the source of the original data, enabling comprehensive oversight of network traffic regardless of its physical location.

This dual structure of local and remote configurations expands the flexibility and utility of flow mirroring, making it an essential tool for network administrators who need to analyze traffic patterns, troubleshoot issues, or ensure security across distributed networks. The other statements either limit the functionality of flow mirroring or outright dismiss its relevance, which does not align with the reality of its applications in modern networking practices.
