Refer to the exhibit. An engineer discovers that, if the vPC peer link goes down, half of the devices in VLAN 20 experience connectivity issues with the external networks. Which action resolves the issue?

Explanation

For non-vPC VLANs with orphan, single-attached devices, configure the associated SVIs in the vPC dual-active exclude interface-VLAN list. During a vPC peer-link failure, NX-OS normally disables VLAN interfaces and Layer 3 forwarding on the secondary peer; excluding those SVIs preserves gateway service for devices attached to that peer.
