300-410 Which statement about RSPAN VLAN is correct? Practice Question

Which statement about RSPAN VLAN 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 RSPAN VLAN must be configured with the 'remote-span' command on all switches in the network.

An RSPAN VLAN is a dedicated VLAN used to carry mirrored traffic from source switches to a destination switch. It must be configured as a remote-span VLAN, and no end devices should be connected to it.

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 RSPAN VLAN must be the same as the native VLAN on the trunk.

    Why it's wrong here

    The RSPAN VLAN is typically a separate VLAN; it can be carried over trunks but should not be the native VLAN to avoid mixing with normal traffic.

  • The RSPAN VLAN can be used for normal user traffic if needed.

    Why it's wrong here

    RSPAN VLAN is reserved for mirrored traffic; using it for user traffic can cause loops and performance issues.

  • The RSPAN VLAN must be configured with the 'remote-span' command on all switches in the network.

    Why this is correct

    The 'remote-span' command is required on the VLAN to prevent it from being used for normal traffic and to allow it to be flooded across the network.

  • The RSPAN VLAN must be pruned from all trunk links to avoid unnecessary flooding.

    Why it's wrong here

    The RSPAN VLAN must be allowed on trunk links to carry mirrored traffic; pruning would block it.
