D. Rogue server is the BEST explanation for the physical address of the DHCP server changing without the network connection being lost. A rogue DHCP server is a device that has been set up incorrectly or maliciously to act as a DHCP server on a network, providing IP addresses to clients. When a rogue DHCP server is present on the network, it can cause network issues such as IP address conflicts, and it can change the IP address of the legitimate DHCP server.

The BEST explanation for the observed change in the physical address of the DHCP server without losing the network connection is: D. Rogue server A rogue DHCP server is an unauthorized DHCP server on the network that can distribute IP addresses to clients. When a rogue DHCP server is introduced into the network, it can cause clients to receive IP addresses from the unauthorized server instead of the legitimate DHCP server. This can result in changes to the physical address (MAC address) associated with the DHCP server. Options A (Server upgrade), B (Duplicate IP address), and C (Scope exhaustion) are less likely to explain a sudden change in the physical address of the DHCP server. A rogue server is a common reason for unexpected changes in DHCP server behavior.
