A. B. C. D.B.
The correct answer is B. CPU utilization.
When the logging level is set to debugging, the switch generates a significant amount of log data, which requires additional processing power to handle. If the CPU utilization is already high, the switch may struggle to keep up with the added workload and stop responding to requests.
Therefore, the technician should check the CPU utilization to determine if it is causing the issue. If the CPU utilization is consistently high or spikes significantly when the logging level is set to debugging, the technician may need to consider upgrading the switch or limiting the amount of data generated by the logging.
Option A, Audit logs, is incorrect because audit logs are used to track user activity and changes made to network devices. While audit logs may be helpful in identifying unauthorized activity or changes, they would not be relevant to troubleshooting this issue.
Option C, CRC errors, is incorrect because CRC errors are typically caused by a physical issue, such as a faulty cable or interface. While CRC errors can cause network performance issues, they are not directly related to the switch's ability to handle logging data.
Option D, Jitter, is incorrect because Jitter is a metric used to measure the variation in latency in a network. While Jitter can impact network performance, it is not relevant to this issue, as the switch is not responding to requests intermittently, indicating a processing issue.
