Refer to the exhibit. An engineer configures the trunk and proceeds to configure an ESPAN session to monitor VLANs 10, 20, and 30. Which command must be added to complete this configuration?
A.
Device(config-mon-erspan-src-dst)# no vrf 1
B.
Device(config-mon-erspan-src)# no filter vlan 30
You cannot include source VLANs and filter VLANs in the same session

The trick is that only VLAN 10, 20, and 30 are allowed, nothing more. So, by removing "filter vlan 30" we can monitor all traffic on the interface. Therefore, we can monitor vlan 10, 20, and 30.
Mostly come for the comments. However, I want to thank you guys from the community. I actually learn a lot from everyone here. Thank for the links and resources. The knowledge transfer is appreciated.
I'll go for B since vlan 30 is supposed to be monitored
