What is the most likely DHCP snooping trust state configuration on a switch for ports connected to other devices?

In a network configured with DHCP snooping, the trust state configuration of ports is essential for preventing unauthorized DHCP servers from operating on the network. Ports connected to trusted devices, such as other switches or servers that are legitimate sources of DHCP packets, must be marked as trusted. This allows DHCP messages to pass through without restriction.

The option indicating that the port connected to switch SW1 is trusted aligns with this principle, as typically, a switch connecting to another switch (like SW1) would be expected to act as a legitimate DHCP server or relay. This means it needs to send DHCP offer messages to devices requesting IP addresses. In contrast, ports connected to end-user devices, such as PCs, would usually be configured as untrusted. This prevents these devices from sending any DHCP server responses, safeguarding the network from potential attacks or misconfigurations.

Given this understanding of DHCP snooping configurations, designating the port connected to switch SW1 as trusted reflects proper network security practices, allowing legitimate DHCP traffic while securing the network from potential threats coming from untrusted endpoints.
