Refer to the exhibit. SwitchC connects HR and Sales to the Core switch. However, business needs require that no traffic from the Finance VLAN traverse this switch. Which command meets this requirement?

Explanation:
From the "show vlan brief" we learn that Finance belongs to VLAN 110 and all VLANs (from 1 to 1005) are allowed to traverse the trunk (port-channel 1). Therefore we have to remove VLAN 110 from the allowed VLAN list with the "switchport trunk allowed vlan remove " command. The pruning feature cannot do this job as Finance VLAN is active. Three major building blocks that make up SDA: the control plane, the data plane and the policy plane.SD-Access + Control-Plane based on LISP + Data-Plane based on VXLAN + Policy-Plane based on TrustSec
