QUESTION 17 OF 25

What are the most important communications network performance metrics, and how do you monitor them?

"The majority of my time as a network administration manager is spent monitoring the performance of the network. The key metric I focus on is bandwidth since this dictates the data transmission rates and the amount of network traffic the system can accommodate. Other metrics include latency, packet loss, throughput, and connectivity. There are a number of network management tools available, but the one key characteristic I look for is that the tool has a consolidated dashboard that enables my team to view the complete network and all these metrics on a single screen."

As an ICT Professional, it is important that you understand how network performance is monitored and optimized. The interviewer knows this and is attempting to see how you accomplish maximizing the speed and performance of a communications network. This is why they are hiring you, so this may be one of the more important questions you will be asked. Again, it should be easy for you to respond to this question if you keep this in mind and rely on your experience in this field.

"I believe the most important network performance metric is bandwidth, which is the maximum data transmission rate possible on a network. Other metrics I use to determine how the network is performing include throughput, latency, packet loss, retransmission, and availability. I monitor these through a consolidated dashboard which provides me and my team with the performance data on a real-time basis."
