Explanation

POAP (Power On Auto Provisioning) is correct because it is specifically designed to automate the zero-touch deployment of Cisco Nexus switches - when a switch powers on with no startup config, POAP contacts a DHCP server, locates a script server, then automatically downloads and installs the correct software image and configuration file, requiring no manual intervention.

• A (Configuration Synchronization) is wrong - this feature synchronizes configurations between vPC peer switches to keep them consistent, not for initial deployment automation.
• C (REST) is wrong - REST is an API architectural style/protocol used for programmatic communication with the switch, not an image/config deployment mechanism.
• D (NX-API) is wrong - NX-API is Cisco's API framework that allows programmatic access to NX-OS via REST or JSONRPC, used for management and automation scripting, not zero-touch provisioning.

Memory tip: Think POAP = "Plug in, Open box, Auto-Provision" - it's the feature that handles the entire bring-up process the moment a new switch is powered on for the first time.
