Switch2 is not allowing VLAN 70 which is used on Switch1 for RSPAN
So we must allow it -> Option B is correct (although it would not allow VLAN 81 to 90 to go through).
"An external packet capture device is connected to switch2 interface GigabitEthernet1/2" so we must configure Gi1/2 as the destination port.
For your information, this is how to configure Remote SPAN (RSPAN) feature on two switches.
Traffic on FastEthernet0/1 of Switch 1 will be sent to Fa0/10 of Switch2 via VLAN 40.
+ Configure on both switches
Switch1,2(config)#vlan 40
Switch1,2(config-vlan)#remote-span
+ Configure on Switch1
Switch1(config)# monitor session 1 source interface FastEthernet 0/1
Switch1(config)# monitor session 1 destination remote vlan 40
+ Configure on Switch2
Switch2(config)#monitor session 5 source remote vlan 40
Switch2(config)# monitor session 5 destination interface FastEthernet 0/10

Data Traffic Blocked between VTP Domains
Sometimes it is required to connect to switches that belong to two different VTP domains. For example, there are two switches called Switch1 and Switch2. Switch1 belongs to VTP domain cisco1 and Switch2 belongs to VTP domain cisco2. When you configure trunk between these two switches with the Dynamic Trunk Negotiation (DTP), the trunk negotiation fails and the trunk between the switches does not form, because the DTP sends the VTP domain name in a DTP packet. Because of this, the data traffic does not pass between the switches.

A next gene ation firewall adds additional features such as application control, integrated intrusion prevention (IPS) and often more advanced threat prevention capabilities like sandboxing.
