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 allowed on all trunk links between the source and destination switches.
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.
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 allowed on all trunk links between the source and destination switches.
Why this is correct
Correct because the RSPAN VLAN carries mirrored traffic across the network and must be permitted on all intermediate trunks.
- ✗
The RSPAN VLAN can be used for normal data traffic if needed.
Why it's wrong here
Incorrect because the RSPAN VLAN is dedicated to carrying mirrored traffic; using it for data traffic can cause issues.
- ✓
On the destination switch, the RSPAN destination port is placed into the RSPAN VLAN.
Why this is correct
Correct because the destination port must be in the RSPAN VLAN to receive the mirrored traffic.
- ✗
RSPAN supports egress mirroring on the source switch.
Why it's wrong here
Incorrect because RSPAN on the source switch only supports ingress mirroring; egress is not supported.
- ✓
The RSPAN VLAN must be configured on all switches in the path between source and destination.
Why this is correct
Correct because each switch in the path needs to have the RSPAN VLAN defined to forward the mirrored traffic.
