The correct timeframe for how long a MAC address can remain unconnected to a network before it expires is six weeks. This setting helps maintain network security and efficiency by ensuring that devices do not indefinitely hold on to MAC addresses if they are not actively participating in the network.

If a device does not connect to the network for this duration, its MAC address may be reassigned or freed up for use by other devices. This reassignment process helps prevent network congestion and allows new devices to seamlessly access the network, contributing to overall operational efficiency.

The other options reflect shorter or longer timeframes that do not align with the established standard for MAC address expiration when a device is not connecting. Understanding this timeframe is crucial for network management and helps support professionals maintain an organized and secure networking environment.
