CompTIA Network+ N10-009 Practice Question

Checking the current bandwidth usage and availability is the correct first step because increased latency during peak hours often indicates that bandwidth is being saturated. By understanding the usage patterns and identifying any bandwidth-hungry applications, a technician can take steps to manage the load or potentially increase bandwidth to reduce congestion, thus decreasing latency. Configuring Quality of Service for prioritization might be necessary if the bandwidth is not sufficient, but first, the usage needs to be assessed. Upgrading firmware or inspecting the physical layer might not directly relate to solving a congestion-induced latency issue during peak hours without first confirming the root cause is due to bandwidth issues.
