Latency Diagnosis Quiz

What you'll be asked

1. Which command is most commonly used to measure the round-trip time (RTT) of packets between a source and a destination to diagnose network latency?
2. You notice high latency on a load-balanced web application. Which metric would best help you determine if the load balancer itself is the bottleneck?
3. If you observe high latency to a backend server, but the network path shows no packet loss and low latency to the server's gateway, what is the most likely cause?
4. When using a Round Robin load balancing algorithm, why might one server experience significantly higher latency than the others?
5. You are troubleshooting latency in a distributed system using 'traceroute'. You notice that latency increases significantly at a specific hop and remains high for all subsequent hops. What does this indicate?
