Network users complain that the network is running very slowly. Upon investigation, a network technician discovers CPU spikes and exhausted memory resources on all the network devices. Also, numerous syslog messages are being generated that note continuous MAC address relearning. What is the most likely cause of the problem?

Question:
Network users complain that the network is running very slowly. Upon investigation, a network technician discovers CPU spikes and exhausted memory resources on all the network devices. Also, numerous syslog messages are being generated that note continuous MAC address relearning. What is the most likely cause of the problem?

• The routing protocol has been misconfigured and a routing loop is evident.
• Keepalives are expected but do not arrive.
• The dynamic routing protocol has not yet converged the network.
• An incorrect encapsulation has been configured on one of the trunks that connect a Layer 2 device to a Layer 3 device within the affected segment.
• A Layer 2 forwarding loop condition is present.
