Refer to the exhibit. During a maintenance window for the Nexus switch pair, one Cisco Nexus chassis was taken offline for maintenance. The primary Cisco Nexus switch remained stable throughout the maintenance window. After completing work on the chassis, the administrator wants to bring the second switch back online. The administrator checks the status of the disconnected switch that was removed from the vPC during maintenance. The engineer must reconnect the peer chassis seamlessly with the primary vPC peer without a traffic interruption. Which action accomplishes this goal?

Explanation

A vPC peer with a TRUE primary sticky bit wins the primary election regardless of configured role priority. Reapplying the peer’s existing vPC role-priority clears the sticky bit; this prevents a role transition on the already forwarding peer when the peer-keepalive and peer-link are restored, avoiding the associated vPC traffic interruption.
