A sensor must see a copy of the traffic on a data-center link. The switch cannot be configured for a mirror session. Which tool still provides the copy?
Select an answer to reveal the explanation.
Short Explanation
The switch will not make a photocopy, so you put a photocopier in the line itself. An inline tap copies the link without asking the switch for a mirror session. A mirror you cannot configure, a toner, and a name lookup do not hand the sensor those packets.
Full Explanation
A network tap sits in the link and copies frames to a sensor without depending on a switch feature. The data-center switch cannot be configured for a mirror session, and the sensor still needs a copy, so an inline tap is the tool that provides it. Port mirroring is the switch feature the stem says cannot be configured. It is the right tool on a switch that supports it, and it is unavailable here. A tone generator places an analog tone on copper so a probe can find the pair. It does not copy packets. A DNS lookup resolves names. It does not export a copy of a link. Exam caveat: an inline tap is in the path, so a failed tap can take the link down. Use a tap rated for the link and plan the insertion window. Operational check: insert the tap in a maintenance window, confirm the sensor sees both directions, and confirm the original link still forwards. Use a tap rated for the link speed so the insertion does not become the outage.
