Why is it important to record baseline measurements of a prototype network?
Test results show security weaknesses after the baseline tests are run.
The baseline is the point at which the network is operating at its fullest potential.
Baseline measurements define a point at which network traffic has exceeded the designed capabilities of the network.
Test results are compared to the baseline to see how the test conditions increase processor use or decrease available bandwidth.*****
