CIT 247 Lab 5: Basic Router Configuration
Instructions:
Please answer the questions below and include screenshots when requested.
When you are finished, add your last name or NKU username to the beginning of this
document’s filename. After this, upload this lab report alongside your GNS3 work to Canvas.
*If you worked with a lab partner, please add his or her name after yours and separate the names
with a semicolon. If not, simply delete the partner’s placeholder text.
Questions:
Q1.1: How many broadcast domains are in your topology? Explain why, specifying which
devices are dividing them. If needed, review the Module 1 learning materials.
To determine the number of broadcast domains, count each segmented network. Routers
divide broadcast domains, so each interface of a router typically represents a new
broadcast domain.
Q2.1: Take one or two screenshots of the results from the show command on both routers
with the IP addresses configured.
Q2.2: How were the routing tables populated? What kinds of routes are shown?
Directly Connected Routes
: These are routes to networks that the router is directly
connected to. When you configure an IP address on a router's interface and activate it, the
network attached to that interface is automatically added to the router's routing table.
Local Routes
: These are routes to the IP addresses of the router's own interfaces. Each IP
address assigned to the router's interfaces gets a local route in the routing table, indicating
that the router itself is the destination for packets sent to these IP addresses.
When you configure and enable interfaces on a router, the routing table is automatically
updated with these directly connected and local routes.
Q3.1: Document the results of each ping test with the table below. Ping all the listed devices
from PC-1, then specify whether each ping test succeeded and explain the results. Your
explanations should discuss:
The echo requests and echo replies (i.e., how the traffic was forwarded from and then
back to PC-1).
The routing decisions PC-1 and, if applicable, the routers made (Hint: PC-1’s routing
decision is based on whether the destination IP address is inside or outside the
computer’s local subnet).
Any relevant steps from the IPv4 routing process. This is discussed in pages 369-371 of
your textbook, as well as this module’s lecture and PowerPoint slides.
Minimum length is not specified, but please make sure your answer is thorough and at
least mentions the routing process steps that occurred in each ping test. PING TEST
(From PC-1)
SUCCESS?
(YES / NO)
EXPLANATION
IOU1:
192.168.1.2
yes
PC-1 successfully communicates with IOU1, as they are on the same subnet (192.168.1.0/24).
R1 fa0/1:
192.168.1.1
yes
Successful ping to R1's interface in the same subnet as PC-
1, indicating direct local network communication.
R1 fa0/0:
192.168.0.1
yes
PC-1 can reach R1's different subnet interface, showing R1
correctly handles local routing.
R2 fa0/0:
192.168.0.2
no
Failure to ping R2's interface suggests a routing issue or link problem between R1 and R2.
R2 fa0/1:
192.168.2.1
no
"Destination host unreachable" error indicates PC-1 cannot find a route to the 192.168.2.0 network.
PC-2:
192.168.2.100
no
Similar to the above, PC-1 cannot reach PC-2 on a different subnet due to lack of routing information
Q4.1: Specify the following IP addresses in the extended ping:
Source IP address in echo request:
192.168.1.1

Event Listeners
Return to the mas_register.js file in your editor. Directly below the initial comment section, insert an event listener for the window load event. Run an anonymous function in response to the event containing the following commands:
Call the calcCart() function (which you will create shortly.)
Create an onclick event handler for the regSubmit button that runs the sessionTest() function when the button is clicked.
Create onblur event handlers for the input boxes with the ids: fnBox, lnBox, groupBox, mailBox, phoneBox, and banquetBox, running the calcCart() function in response to each event.
Create an onchange event handler for the sessionBox selection list, running the calcCart() function when the selection list is changed.
Create an onclick event handler for the mediaCB check box, running the calcCart() function in response.

Step 2: Create the insertartist.php file
Create the insertartist.php file that takes the data from the artist.html form, connects to the database, and successfully inserts the data into the artist table. A message should be displayed to confirm that the record has been added.

response page checks username and
password against arrays of valid usernames
and passwords (normally this is done
against a database - we'll change it later)
If valid - saves username to cookie, and sets
session variable LoggedIn to TRUE. If not,
sets the session variable to FALSE.
Displays link to "content page" (the page
you're protecting).

I have already created my database and the connection and some of the code but am stuck on these parts."Home" and "Create Account" pages
The index.php file will ask the user to log in to the system with a login form
If they're already logged in, the home page will NOT show the login form. It will show a "welcome to our store" type of message instead even if they click on the "home" button in the navigation.
The create-account.php page has them fill out a form for creating an account.
Use real-time JavaScript validation (and regex) to:
Verify that the password and "verify password" match as they are typing.
Verify that the password contains at least one number and is at least 8 characters long

Find Running Total by Date: Your objective is to find the running total by date using the data.
Insert a Pie Chart: You will create a pie chart from the data in this problem, you will need to insert slicer to the pivot table. Use the calculated Field to find the sales tax which is 5% of the total sales.

Besides there is an options menu that includes two options in the main activity. These are: 1. New Student 2. Exit When you click on the “New Student” option, a “New Activity” opens and the teacher enters the Student ID, Visa, Final Number, Phone Number and clicks the Add button. Thus, the student's information is recorded in the database. In addition, the grade point average is calculated by taking 40% of the student visa and 60% of the final. Both the grade point average and this student's phone number are sent to MainActivity. When registration is complete, the main activity is updated to include the list of the currently added student. In addition, if the average score coming from the main activity to NewActivity is equal to or greater than 50, an SMS is sent directly to the student's phone number indicating that he or she has passed the course. For this process, necessary permissions are obtained by following the permission procedure. If the student's average is less than…
