XYZ Company has an enterprise network consisting of core backbone, corporate campus, two data centers, regional distribution centers, and internet edge with DMZ. The network implements VLAN segmentation, port security, firewalls, and switches to protect against attacks. The network engineers are asked to create a detailed troubleshooting and maintenance plan as a template for other administrators. The plan will include daily, weekly, and monthly maintenance processes, and an overall troubleshooting methodology for maintaining network health.

Assignment 2: XYZ Company Troubleshooting and Maintenance Plan
Due Week 10 and worth 170 points
Use the same scenario from Assignment 1. In addition, XYZ Company is
heavily invested in e-Commerce with all retail locations’ Point of Sale
systems connected so that it maintains a dynamic inventory and
automatically generates restock orders. The XYZ Company engineers
have configured the WAN-based Intranet using IPSec to support all of
these locations via encrypted VPN links connected to the nearest
regional distribution center.
XYZ Company has an enterprise network consisting of a core backbone,
corporate campus, two (2) data centers, regional distribution centers,
and Internet Edge with a DMZ. For better security, the retail Point of
Sale systems does not have direct Internet access. At the corporate
campus, the seven (7) departments in the company include Finance,
Operations, Human Resources, Sales, Marketing, Technology, and the
Corporate Executive Office. The company provides appropriate
computing equipment to all of its employees. It also provides remote
access for the system and network administrators using company-
provided encrypted laptops and two (2) factor authentication to access
the XYZ Company network in order to provide off-hours support.

2. Due to recent major security concerns in its campus network, XYZ
Company redesigned the infrastructure so that it:
Implements VLAN segments segregating servers, workstations, and
printers on separate VLANs.
Implements Port Security to protect against MAC layer attacks.
Implements firewalls between VLANs to protect against VLAN attacks.
Protects against spoofing attacks.
Secures the network switches.
Based on your prior success in other networking endeavors, your
supervisor has asked you to write a detailed troubleshooting and
maintenance plan for your fellow network engineers for when they are
on call. Additionally, this plan will be the template for the other system
administrators to write troubleshooting and maintenance plans for their
areas of expertise.
Write a six to ten (6-10) page paper in which you:
Describe the routing and switching infrastructure and the routing
protocols used in the environment.
Illustrate the secure routing and switching infrastructure topology
through the use of graphical tools in Microsoft Word or Visio, or an
open source alternative such as Dia. Include a depiction of all core
elements of the routing and infrastructure topology using color-keyed
symbols to indicate the functionality of each item. Note: The graphically
depicted solution is not included in the required page length.

3. Suggest one (1) overall troubleshooting methodology that you would use
for your troubleshooting and maintenance plan. Provide a rationale to
support your suggestion.
Create the daily, weekly, and monthly maintenance processes that your
fellow network engineers must follow in order to maintain the health of
the network. Provide a rationale to support of your suggestion(s).
Analyze whether or not other system administrators can use the template
of your plan to write troubleshooting and maintenance plans for their
areas of expertise. Justify your response.
Use at least three (3) quality resources in this assignment.Note:
Wikipedia and similar Websites do not qualify as quality resources.
Your assignment must follow these formatting requirements:
Be typed, double spaced, using Times New Roman font (size 12), with
one-inch margins on all sides; citations and references must follow APA

instructions.
Include a cover page containing the title of the assignment, the student’s
name, the professor’s name, the course title, and the date. The cover
page and the reference page are not included in the required assignment
page length.
The specific course learning outcomes associated with this assignment
are:
Describe and develop maintenance methods, and processes and
procedures through the use of networking tools, resources, and
techniques.
Summarize and develop troubleshooting processes for enterprise
networks.

4. Explain and plan the troubleshooting related to network performance.
Describe, maintain, and troubleshoot network security issues for branch
and remote office locations.
Use technology and information resources to research issues in
internetworking troubleshooting.
Write clearly and concisely about internetworking troubleshooting using
proper writing mechanics.
