Which of the following is the control when observing network bandwidth patterns over time?

A.
Network log

B.
Baseline

C.
Flow data

D.
Interface statistics

Explanation:
To successfully baseline a network it is important to consider two functions; performance at
protocol level and performance at application level. There are many significant metrics to consider
at the protocol level, but only a few which are critical. The most important is bandwidth utilization

compared with bandwidth availability. The most likely cause of poor network performance is
insufficient bandwidth. Trending bandwidth utilization allows you to recognize problem areas,
provide enough bandwidth to reach performance objectives, and predict future capacity
requirements. Changes in bandwidth utilization patterns also provide a clear indication of network
usage alterations, such as a change in end-user behavior, or the unauthorized addition of an
application.
