A technician would like to track the improvement of the network infrastructure after upgrades. Which of the following should the technician implement to have an
accurate comparison?

A.
Regression test

B.
Speed test

C.
Baseline

D.
Statement of work

Explanation:
In networking, baseline can refer to the standard level of performance of a certain device or to the normal operating capacity for your whole network. High-quality
documentation should include a baseline for network performance, because you and your client need to know what “normal” looks like in order to detect problems
before they develop into disasters.
A network baseline delimits the amount of available bandwidth available and when. For networks and networked devices, baselines include information about four
key components:
Processor
Memory
Hard-disk (or other storage) subsystem
Network adapter or subsystem
