A company has reported sluggish network performance. After questioning users and gathering information, it was determined that the issue occurs sporadically but intensifies during business hours. Initial investigations into the infrastructure do not indicate any hardware failures. Which of the following should be done NEXT to identify the cause of the network's degraded performance?
Test the integrity of the cables connecting high-usage network areas.
Reboot the main network router to refresh the network's routing table and clear any potential bottlenecks.
Examine the network traffic logs and monitor for peak usage times and possible congestion during business hours.
Compare the performance of the network across different subnets to identify a segmentation issue.
