Explanation Explanation: You can create up to a total of 64 SPAN and ERSPAN sessions to define sources and destinations on the local device.You can also create a SPAN session to monitor multiple VLAN sources and choose only VLANs of interest to transmit on multiple destination ports. For example, you can configure SPAN on a trunk port and monitor traffic from different VLANs on different destination ports. You can configure a particular destination port in only one SPAN session. Traffic from a non-source VLAN is discarded when it arrives on a source VLAN.

|
| Option C | 1 and 4 - 100
|
| Option D | 3 and 4 - 100

| Correct Answer | D |
Explanation Explanation: Traffic on the native vlan does not get tagged as it crosses a trunk, so there is no dot1q tag in the first place to be filtered. And you dont need to allow the native vlan. But if we force to tag the native vlan (with the switchport trunk native vlan tag command) then if the native vlan is not in the allowed vlan list it will be dropped.
