An administrator is writing a script to periodically log the IPv6 and MAC addresses of all the devices on a network segment.
Which of the following switch features will MOST likely be used to assist with this task?

The switch feature that is most likely to be used to assist with periodically logging IPv6 and MAC addresses of devices on a network segment is Neighbor Discovery Protocol (NDP).
Neighbor Discovery Protocol is a protocol used in IPv6 networks to discover other devices on the same network segment. It allows a device to determine the link-layer address (MAC address) of a neighbor, as well as the state and configuration of neighboring devices.
When a device on the network segment wants to send a packet to another device, it first sends a Neighbor Solicitation message to request the link-layer address of the destination device. The destination device responds with a Neighbor Advertisement message that includes its MAC address. The source device can then cache this information for future use.
An administrator could use NDP to periodically scan the network segment for devices and their MAC addresses. This could be accomplished using a script that sends out periodic Neighbor Solicitation messages and collects the responses. The script could then log the IPv6 and MAC addresses of all devices that respond.
Spanning Tree Protocol (STP) is used to prevent loops in network topologies, and does not assist with discovering devices on a network segment. Link Aggregation Control Protocol (LACP) is used to combine multiple physical links into a single logical link, and does not assist with discovering devices on a network segment. Address Resolution Protocol (ARP) is used in IPv4 networks to discover the link-layer address of a neighbor, and is not directly used in IPv6 networks.
