A technician is troubleshooting intermittent connectivity between devices and viewing the following syslog entries from a switch:
Which of the following are these entries indicative of?
.
Which of the following are these entries indicative of?
.
Correct Answer: D
Explanation
The syslog entries are indicative of link flapping, which is when a switch port rapidly transitions between the up and down states. This can cause intermittent connectivity issues, network instability, and increased CPU utilization on the switch. Link flapping can be caused by various factors, such as faulty cables, misconfigured interfaces, duplex mismatches, or network attacks. To troubleshoot link flapping, the technician should check the physical layer, verify the interface settings, and monitor the network traffic for anomalies.
