Which two statements about local SPAN configuration are true? (Choose two.)
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 destination port must be in STP forwarding state to forward traffic.
Local SPAN copies traffic from source ports or VLANs to a destination port on the same switch. The destination port must be in STP forwarding state to forward traffic, but it does not participate in STP for the SPAN session. The source can be a port or VLAN, but not a port-channel interface directly; however, individual member ports can be sources. The destination port cannot be used as a source port simultaneously.
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 destination port must be in STP forwarding state to forward traffic.
Why this is correct
Correct because the destination port must be forwarding to send the mirrored traffic out.
- ✗
A SPAN destination port can also be used as a source port in another SPAN session.
Why it's wrong here
Incorrect because a destination port cannot be used as a source port in any SPAN session.
- ✗
A SPAN source can be a single port, a VLAN, or an EtherChannel interface.
Why it's wrong here
Incorrect because an EtherChannel (port-channel) cannot be a SPAN source; only individual member ports can be sources.
- ✓
When a VLAN is configured as a SPAN source, all active ports in that VLAN are monitored.
Why this is correct
Correct because VLAN-based SPAN mirrors all packets on all active ports in the specified VLAN.
- ✗
SPAN destination ports participate in Spanning Tree Protocol normally.
Why it's wrong here
Incorrect because SPAN destination ports are put into a forwarding state and do not participate in STP for the SPAN session.
