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
