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
✓
SPAN mirrors traffic only on the local switch.
SPAN mirrors traffic locally on the same switch. RSPAN uses a dedicated VLAN to carry mirrored traffic across switches. SPAN can monitor both ingress and egress traffic. RSPAN supports only ingress mirroring on source ports, not egress. SPAN cannot be used across switches without RSPAN or ERSPAN. RSPAN does not require a separate management VLAN.

- ✓
RSPAN uses a dedicated VLAN to transport mirrored traffic across multiple switches.
Why this is correct
Correct because RSPAN traffic is carried over an RSPAN VLAN that must be configured on all intermediate switches.
- ✗
SPAN can be used to mirror traffic between switches without additional configuration.
Why it's wrong here
Incorrect because SPAN is local; to mirror across switches, RSPAN or ERSPAN is required.

Why it's wrong here
RSPAN supports both ingress and egress mirroring on the source switch. This statement is accurate.
