   A company's employees report that video conferencing quality is poor during peak hours, but speed tests run at the same time show high throughput. The network administrator suspects that the issue is not bandwidth. Which additional measurement would best help diagnose the problem?

   • AUpgrade the internet plan to a higher bandwidth
   • BCheck the total bandwidth utilization of the link
   • CMeasure latency and packet loss during peak hours
   • DRun a speed test to a different server

   A network engineer needs to measure the maximum achievable throughput between two servers on a local network. The engineer wants to isolate the network path from internet variables. Which tool should the engineer use?

   • ATraceroute, because it shows the path and the delay at each hop, which can be used to estimate throughput.
   • BIperf, because it can generate TCP or UDP traffic between two hosts and report the achieved throughput.
   • CAn internet speed test, because it measures the throughput to a public server and reflects the local network performance.
   • DPing, because it measures the round-trip time and can be used to calculate throughput.

   A company has a 1 Gbps internet link. During peak hours, employees report slow performance, but a speed test shows 900 Mbps throughput. The network administrator needs to decide whether to upgrade the link. Which approach would best determine if the link is the bottleneck?

   • ACheck the firewall logs for blocked traffic
   • BMonitor throughput and latency on the link during peak hours and correlate with employee complaints
   • CRun a speed test from multiple employees' computers simultaneously
   • DUpgrade the link to 2 Gbps and see if complaints stop

   A company's remote employees report that large file transfers to the office are much slower than the office's 500 Mbps internet connection should allow. The office link is not saturated, and the employees have strong local internet connections. Which factor is most likely reducing throughput in this scenario?

   • AHigh latency on the WAN connection between the employees and the office
   • BThe office link is experiencing packet loss due to a faulty switch
   • CThe office link's bandwidth is actually lower than 500 Mbps
   • DThe employees' local internet connections have higher bandwidth than the office link
