Which three statements about RSPAN are true? (Choose three.)
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
✓
RSPAN uses a dedicated VLAN that is trunked between switches to carry mirrored traffic.
RSPAN uses a dedicated VLAN to transport mirrored traffic across switches. The RSPAN VLAN must be created on all switches in the path and should not be used for user traffic. Trunk ports carry the RSPAN VLAN, and the destination switch receives the traffic on an RSPAN destination port. The RSPAN VLAN must not be pruned from trunks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
RSPAN uses a dedicated VLAN that is trunked between switches to carry mirrored traffic.
Why this is correct
Correct because the RSPAN VLAN is a special VLAN used exclusively for transporting mirrored packets across switches.
- ✗
The RSPAN VLAN can also be used for regular user data traffic if needed.
Why it's wrong here
Incorrect because the RSPAN VLAN must be dedicated solely for RSPAN traffic; user traffic is not allowed.
- ✓
The RSPAN VLAN must be allowed on all trunk links between the source and destination switches.
Why this is correct
Correct because the RSPAN VLAN must be present on all intermediate trunks to ensure the mirrored traffic reaches the destination.
- ✗
The RSPAN destination port can be a regular access port in the RSPAN VLAN.
Why it's wrong here
Incorrect because the RSPAN destination port must be configured as a switchport in RSPAN VLAN mode (monitor session destination) and is not a regular access port.
- ✓
RSPAN requires that all switches in the path support the RSPAN feature.
Why this is correct
Correct because all switches involved in transporting the RSPAN VLAN must support the RSPAN feature to properly handle the mirrored traffic.

Same concept, more angles
3 more ways this is tested on 350-401
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which three statements about RSPAN configuration and behavior are true? (Choose three.)
medium- ✓ A.The RSPAN VLAN must be created on all switches that participate in the RSPAN session.
- B.The RSPAN destination port must be configured in access mode and assigned to the RSPAN VLAN.
- ✓ C.Trunk ports between switches must allow the RSPAN VLAN and should not prune it.
- ✓ D.The RSPAN source switch encapsulates the mirrored frames with the RSPAN VLAN ID.
- E.RSPAN can only monitor source ports on the same switch as the destination port.
Why A: RSPAN requires a dedicated VLAN that is not used for user traffic. The RSPAN VLAN must be created on all switches in the path, and the destination switch must have a destination port configured. The RSPAN VLAN should not be pruned from trunks. The source switch sends mirrored frames into the RSPAN VLAN, and the destination switch extracts them.
Variation 2. Which three statements about RSPAN are true? (Choose three.)
hard- ✓ A.The RSPAN VLAN must be allowed on all trunk links between the source and destination switches.
- B.The RSPAN VLAN can be used for normal data traffic if needed.
- ✓ C.On the destination switch, the RSPAN destination port is placed into the RSPAN VLAN.
- D.RSPAN supports egress mirroring on the source switch.
- ✓ E.The RSPAN VLAN must be configured on all switches in the path between source and destination.
Why A: RSPAN uses a dedicated VLAN that must be allowed on trunk links between switches. The RSPAN VLAN should not be used for any other traffic. The destination port on the remote switch is placed in the RSPAN VLAN. RSPAN does not support egress mirroring on the source switch (only ingress). The RSPAN VLAN does not participate in STP normally, but it can be configured to do so.
Variation 3. Which statement about RSPAN is true?
medium- ✓ A.RSPAN uses a dedicated VLAN to transport mirrored traffic from source to destination switches.
- B.RSPAN can only monitor traffic within the same switch.
- C.RSPAN requires the use of ERSPAN encapsulation.
- D.RSPAN destination ports must be in trunk mode.
Why A: RSPAN (Remote SPAN) uses a dedicated RSPAN VLAN to carry mirrored traffic from the source switch to one or more destination switches across a network. This allows monitoring of traffic on remote switches, unlike local SPAN which is confined to a single switch. The RSPAN VLAN must be configured on all intermediate switches and trunked appropriately to ensure the mirrored traffic reaches the destination.
