A network administrator observes that two departments, which are supposed to operate on separate network segments, are unexpectedly able to interact with each other. Upon inspection, it is found that several devices meant for secure departmental communication are wrongly grouped with general office network traffic. What could be the most probable cause of this configuration error?
Incorrect zone records maintained by the DNS server.
Configuration errors in the switch port settings.
Misconfigurations in the DHCP server settings.
A loop in the routing configuration causing traffic misdirection.
