What is a primary result of a network loop occurring within a switched environment?
Routing loops
MAC address instability
Duplicated IP addresses
Broadcast storm
Network loops cause broadcast storms, which lead to excessive flooding of broadcast frames. This happens because each switch continuously forwards the same frame, multiplying the traffic exponentially. MAC address instability is characterized by the switches learning incorrect MAC addresses due to fluctuations caused by loops, but it's a different symptom and not a direct cause.
Additionally, high CPU usage generally refers to the effect on networking devices trying to process the excessive traffic, and increased latency is a symptom of the degradation in network performance due to the loop’s impact.
