Which interface mode do you use to generate the statdump file that can be converted into an SLR for unobtrusive evaluation?

The correct answer for generating a statdump file that can be converted into an SLR for unobtrusive evaluation is the Tap interface mode.

In Tap mode, the data traffic is mirrored in such a way that it allows for passive monitoring of the network traffic without introducing any delay or overhead to the actual data flow. This mode provides a clear snapshot of the data traversing the network, which is essential for accurately creating the statdump file. The resulting file contains useful statistics and performance data that can be used for analysis and can subsequently be transformed into a Service Level Report (SLR).

Using Tap mode ensures that the evaluation process is unobtrusive, meaning that it does not interfere with the operation of the network. The design of Tap mode is specifically aimed at collecting the data in a way that preserves the integrity of traffic flow while gathering necessary metrics, thus making it the most suitable option for this purpose.
