Characterizing an existing network requires gathering as much information about the network as
possible.Which of these choices describes the preferred order for the information-gathering
process?

A.
Site and network audits, traffic analysis, existing documentation and organizational input

B.
Existing documentation and organizational input, site and network audits, traffic analysis

C.
Traffic analysis, existing documentation and organizational input, site and network audits

D.
Site and network audits, existing documentation and organizational input, traffic analysis

Explanation:

This section describes the steps necessary to characterize the existing network infrastructure and
all sites. This process requires three steps:
Step 1. Gather existing documentation about the network, and query the organization to discover
additional information. Organization input, a network audit, and traffic analysis provide the key
information you need. (Note that existing documentation may be inaccurate.)
Step 2. Perform a network audit that adds detail to the description of the network. If
possible, use traffic-analysis information to augment organizational input when you are describing
the applications and protocols used in the network.
Step 3. Based on your network characterization, write a summary report that describes the health
of the network. With this information, you can propose hardware and software upgrades to support
the network requirements and the organizational requirements.
