Which options is true when using the traffic mirror feature in a switch?

Ethernet headers are preserved exactly as received; SPAN does not rewrite or modify any header fields.

Packet payloads are fully copied to the mirror port - no data is dropped or truncated during the mirroring process.

The original packets are still processed and forwarded normally on the source port; mirroring only adds a copy, it does not interrupt normal switching.

SPAN/port mirroring duplicates every frame - including the complete Ethernet header and full payload - from the monitored port to a capture port. Because nothing is stripped or altered, a sensor or analyzer connected to the destination port can perform a complete, lossless packet capture of all traffic traversing the mirrored interface.
