Examine the RSPAN configuration:

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
✓
It allows VLAN 100 to be used for RSPAN traffic across multiple switches.
The 'remote-span' command designates VLAN 100 as an RSPAN VLAN, allowing it to carry mirrored traffic across switches. This is its primary purpose. While it also prevents user data traffic, that is a secondary effect, not the main purpose.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It allows VLAN 100 to be used for RSPAN traffic across multiple switches.
Why this is correct
Correct. The 'remote-span' command marks VLAN 100 as an RSPAN VLAN, enabling it to carry mirrored traffic across switches in the network.
- ✗
It enables spanning tree on VLAN 100.
Why it's wrong here
Incorrect. The 'remote-span' command does not affect spanning tree; it is unrelated to spanning tree operations.
- ✗
It prevents VLAN 100 from being used for user data traffic.
Why it's wrong here
While it is true that RSPAN VLANs are not used for user data, the primary purpose of the command is to enable the VLAN for RSPAN traffic; preventing user data is a consequence, not the intended purpose.
- ✗
It configures VLAN 100 as a native VLAN.
Why it's wrong here
Incorrect. The 'remote-span' command does not configure a native VLAN; native VLAN is a different concept in trunking.

Variation 1. What is missing from this RSPAN configuration on a switch? monitor session 1 source interface GigabitEthernet1/0/1 both monitor session 1 destination remote vlan 100 Assume VLAN 100 exists but is not configured as an RSPAN VLAN.
medium- ✓ A.The 'remote-span' command under VLAN 100.
- B.An IP address on the destination interface.
- C.A destination interface on the source switch.
- D.The 'no shutdown' command on VLAN 100.
Why A: For RSPAN to work, the VLAN used as the destination remote VLAN must be configured with the 'remote-span' command. Without it, the session will not function correctly.
