Hello. Welcome back.
Let's go certify that Design associate, of course.

From this video, we will begin to introduce characterizing existing that work

In this lesson, we'll learn characterizing the existing network. Characterizing the network is in step two off the design methodology.
In this section, you will learn thio, identify your networks and major features tours to analyze existing network traffic on the tours for outing and monitoring network traffic.
Here's the steps in gathering information.
When arriving at aside, an existing network you need to opt in all the existing documentation. Sometimes no document dated information exists.
You should be prepared to use the tour's toe, obtain information and get access to log in to the network devices. To obtain information,
step one right. Identify properties of the existing network
network topology technologies on the applications, use existing documentation on organization and no input step to perform in that book. Audit that, as detailed to the description to the net off the network

from these slight you can see a network. The overview for

Get some idea about information gathering
When performing a network audit. You have three primary sources of information Existing documentation existing that worker management software tours net validating tours. After gathering the existing documentation, you must obtaining access to the existing management software.
may already have Siskel Prime Tours, a center from which he can opt in hardware mottoes on a confidence and self diversions. You can also attend the existing router and switch configurations. The Net God it should have provided the following information Network devices list hardware specifications,
software versions, configuration of the network devices, all dating tours out. Put the information

you may be able to Upton the required information via manual assessment for a larger network. A manual assessment maybe too time consuming.
So we need to use the network assessment tours. Right Assessment tours include a following

Learning check. Question number one which three sources does the network designer used to collect the information that is used to characterize existing networks? Choose three. A staff in poot Be visual image entry.
Seeing that, we got it.
De traffic and houses.
E server status takes half incident report. Right.
Um, I'll give you a second to think about it.
So we go where the staff in poot that regard it Traffic analysis, Um, you know, because of visual documentary server status sticks incident report are not related. Thio Hall you characterize your existing network is so based on the staffing man input.
Never got it right. Those air traffic analysis all the, you know, information gathered from those. Then I'm gonna help you. Characterizing existing network
question number two. What are the three effective ways to collect the information about existing data networks? Choose three, eh? You the organization. No input.
Be performing the traffic analysis. See, analyze the user mapping off running configure certification,
the performance packager level on it to verify carrier service guarantees e performing that regarded together more detail about it than ever.
F use reporters of that idolizes the marriage because of a customer's existing their work.
G contacted a customer interview regarding an open attack ticket.
I'll give you a second to think. Let's see you use the organizational input performance. Traffic analysis. I analyze the user mapping up running application does. This will not help right
performance package or level audit Thio Verify Carrier service guarantees that we will know how
user reports that analyzes the markings of a customer. Existing network
reports will not help you to crack the information about existing network.
Conducted a customer interview.
Maybe, but it's not ideally the answer. So we go with the A B. I eat. So did you get the right answer?
I hope you did all right.
Summary in today's brief lecture we discussed characterizing existing that work
any questions, sent me an email.
I'll see you in the next video. Bye for now.
