300-410 Practice Question: Runs the following command on switch SW5: SW5#…

A network engineer runs the following command on switch SW5:

SW5# show monitor session 7

Session 7 --------- Type : Local Session Source Ports : Both : Gi0/11 Destination Ports : Gi0/12

Encapsulation : Replicate

Ingress : Disabled

Based on this output, which statement is correct?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The SPAN session will replicate the original VLAN tag on the mirrored traffic sent to Gi0/12.

This is a local SPAN session with source port Gi0/11 and destination port Gi0/12. The encapsulation is set to 'Replicate', which means the mirrored traffic retains its original VLAN tag. This is typical when the destination port is a trunk port and the analyzer expects tagged traffic.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The SPAN session will replicate the original VLAN tag on the mirrored traffic sent to Gi0/12.

    Why this is correct

    The encapsulation type 'Replicate' indicates that the original VLAN tag is preserved.

  • The SPAN session will strip the VLAN tag from the mirrored traffic.

    Why it's wrong here

    'Replicate' preserves the tag; 'Native' strips it.

  • The SPAN session is using RSPAN because the encapsulation is set to Replicate.

    Why it's wrong here

    RSPAN uses a VLAN as destination, not encapsulation type.

  • The SPAN session is misconfigured because encapsulation Replicate is not supported.

    Why it's wrong here

    Encapsulation Replicate is a valid option on many switches.
