What symptoms may be caused by a network loop due to Ethernet's broadcast support?

• A. Users cannot log in to the device remotely
• B. Large number of broadcast packets received on an interface
• C. CPU usage exceeds 70%
• D. A lot of ICMP packets are lost in ping tests

Answer: (A)

A network loop in an Ethernet environment can significantly disrupt network performance and functionality due to its broadcast nature. When a loop occurs, broadcast packets can circulate endlessly, resulting in a variety of symptoms affecting network operations. Receiving a large number of broadcast packets on an interface is a hallmark symptom of a network loop. This continuous flow overwhelms network devices and impacts their ability to manage traffic effectively. High volumes of broadcast traffic can cause congestion, leading to network instability and degradation of service. Additionally, a network loop can cause CPU usage to spike. When packets flood a switch or router, the device must process this excessive traffic, which can push CPU utilization beyond typical operating levels. If the CPU usage exceeds 70%, this often results in sluggish performance, as devices struggle to keep up with the processing demands placed upon them. Loss of ICMP packets is also a symptom that may arise from network loops. Due to the overwhelming nature of the broadcast storms created by the loop, other types of traffic, including pings, can get lost. This reflects the common issue where the network infrastructure becomes unresponsive or performs poorly due to the chaotic network conditions caused by the loop. The answer provided emphasizes a symptom that may not directly illustrate the more observable effects of a network loop,
