Tugas CCNA 4 Lab 3.5.3 Creating a Scope Statement

Lab 3.5.3 Creating a Scope Statement

Step 1: Consider how meeting the project goals will impact the existing network
a. As the network designer, look at the existing network topology and the services that it provides.
Consider how much of the network is affected or changed as a result of the project.
b. Record what areas of the existing network will have to change or will in some way be affected by
meeting the project goals.
Draft informal descriptive notes of these possible changes. Organize these notes under headings
such as:

* • Access Layer
* • Distribution Layer
* • Core Layer
* • Data Center
* • Network Services
* • WAN Access

c. Use word processing software to create a Project Scope document based on these notes.
Step 2: Refine and record the proposed changes to the existing network
a. Distinguish between possible upgrades to existing network resources, such as additional servers or
VLANs, and completely new additional resources, such as QoS and WAN links.
b. Record which areas and users will be affected by these changes.
c. Include these network changes in your Project Scope document.
Step 3: Define the areas of the existing network not covered by the project
It is important to note the parts of the existing network that are not within the areas covered by the project.
These out-of-scope areas are defined so that there is no misunderstanding between the NetworkingCompany and FilmCompany management.
In this case study, for example, providing IP telephony services may be a future consideration, but it is not
within the scope of this project.
Clearly state these out-of-scope areas in your Project Scope document.
Step 4: Compile and present the project scope document
FilmCompany has to agree with your assessment of the Project Scope before you proceed further with the design. An agreement ensures that there is a common understanding about what is included in the network upgrade project and what is not included.
a. Discuss your Project Scope with another student to ensure that the issues you present are clear.
b. Save your Project Scope document and retain it for the next stages of this network design case study.
Step 5: Reflection
It is important that a project have clearly defined boundaries so that all parties know what is included and
what is not. Consider the issues of ensuring that customer business and network needs are satisfied before the scope is broadened beyond what is feasible and required.
What strategies could be used to ensure that a project scope is developed that is clear and appropriate?
• Pastikan bahwa setiap layanan jaringan baru dan teknologi yang tidak termasuk dalam ruang lingkup semata-mata karena mereka dapat, pastikan mereka selaras dengan kebutuhan perusahaan dan tujuan.
• Apakah orang yang berbeda, baik dari perusahaan desain jaringan dan bisnis, meninjau lingkup proyek dan memberikan interpretasi mereka untuk memastikan bahwa itu berarti hal yang sama untuk semua orang.

Tugas CCNA 4 Lab 3.5.2 Creating an Overall Project Goal

Lab 3.5.2 Creating an Overall Project Goal

Step 1: Gather information about the company goals that this network upgrade will facilitate
Consider what FilmCompany sees as benefits that the upgraded network will provide to their business in
terms of their new stadium contract. These business benefits will not be the direct technical improvements
that networking technicians and engineers may see. A business manager does not necessarily see the
network in terms of bandwidth, latency, efficient protocols, or device operation. They are more likely to
consider issues of profitability, flexibility, customer service, and reliability.
As a network designer, you take into account all the information obtained through interviewing the company managers and key members of the staff.
a. Draft informal notes of what you consider to be the business benefits in this case.
b. Use word processing software to create a Project Goal document based on these notes.
c. Organize or group your informal notes and save these in your Project Goal document.
General headings could include:

* • Financial goals
* • Job management goals
* • Customer communication goals

Step 2: Summarize important goals in a list
a. Examine the general goals recorded and summarize these as three or four key points.
Begin each point with a verb, such as Provide, Increase, Improve, or equivalent word. Try to include a measurable achievement if possible.
For example:
Provide the stadium with a broadcast-quality, 30-minute highlight video package within 3 hours of the conclusion of an event.
b. Save the list of important goals in your Project Goal document.
Step 3: Develop an overall project goal statement
a. Write a single statement that introduces the summarized important goals.
The proposed network upgrade will enable FilmCompany to increase its share of
the sports event video market through:

* • Improved response times to customer requests
* • Improved processing and delivery of video content across the network
* • Improved communications access to customer facilities
* • Ability for improved flexibility in meeting customer needs

b. Add this statement to your Project Goal document.
Step 4: Obtain agreement from the company on the project goal statement
FilmCompany has to agree with your assessment of the Project Goal before you proceed further with the
design. If this is agreement is not obtained, the network you design may not meet the FilmCompany overall business requirements. An agreement provides clarification and acknowledgement of why the upgrade is to occur and what it is to achieve.
a. Discuss your Project Goal document with another student and arrive at an agreed-upon Project Goal.
It may be necessary to amend the statement and important goals before agreement is reached.
b. Save your Project Goal document and retain it for the next stages of this network design case study.
Step 5: Reflection
Consider the issue of communication between the network designer and a manager of the company
considering an upgrade of the business network. The network designer is trained in network operation and performance and how to optimize network resources and technologies to best provide network services. To the manager, the network is only one of a number of business tools that the company may use. The business manager probably wants to improve profitability and sees an enhanced network as a tool to help achieve that goal. A business manager is not likely to relate to a goal that is expressed solely in technical terms, such as an upgraded LAN with higher bandwidth, less latency, and maximized server utilization. Although most designers may want to talk about network capabilities, the lifecycle approach is about customer requirements and enabling the business process.
Discuss some strategies that will enable clear communication between a network designer and a business manager so that the resulting Project Goal document represents business needs that ultimately can be met by a network design.
Mahasiswa yang tertarik untuk jaringan, termasuk komputer, sistem TI, dan teknologi, mungkin cenderung terlalu fokus pada aspek teknis desain jaringan. Pada tahap awal siklus desain, penting bagi siswa mengembangkan kesadaran tentang keharusan usaha yang akan meng-upgrade drive jaringan dari alam.

Tugas CCNA 4 Lab 3.3.2 Determining the Router Hardware Options

Lab 3.3.2 Determining the Router Hardware Options
Task 1: Inspect a Cisco 1841 ISR

Step 1: Physically inspect the external features of the router
Examine the router. In the table below, identify and match each item number in the figure with the description. In addition, record the number of each interface and port on the router with the description.
Is a module installed in Slot 0? No
How many Fast Ethernet interfaces does the router have?
2
WIC-2T two serial interfaces
Is a module installed in Slot 1?
No
Which of the modules and ports have the potential to be upgraded to improve the router’s
capabilities?
Slot 0 dan Slot 1, flash card slot

Step 2: Use IOS show commands to inspect the router
a. Referring to the topology diagram, connect the console (or rollover) cable to the console port on the
router and the other cable end to the host computer with a DB-9 or DB-25 adapter to the COM 1 port.
Ensure that power has been applied to both the host computer and router.
b. Establish a HyperTerminal or other terminal emulation program connection to the router.
c. From the privileged EXEC mode prompt of the terminal, issue show run and show flash:
commands.
Record the number and type of interfaces. Typical results are shown.
interface FastEthernet 0/0
interface FastEthernet 0/1
interface Serial 0/0/0
interface Serial 0/0/1
interface VLAN1
Record the details of the memory (DRAM, flash) modules.

different categories of interface card (WIC) supported by the 1841 platform.
e. From Table 6, what feature does the Advanced Integration Module (AIM) enable to be installed in an
1841 router?
VPN encryption

Step 3: Consider possible hardware options
The 1841 ISR has removable and interchangeable modules. Various optional modules can be installed in the router to provide specific capabilities. These modules are installed either by inserting them into slots on the chassis, or by opening the chassis and plugging them into connectors inside.Flash memory and interface cards fit into slots on the chassis and are installed and removed without opening the chassis.
There are three types of interface cards for the 1800 series modular routers:

* • WAN interface cards (WICs)
* • Voice WAN interface cards (VWICs – in data mode only on the Cisco 1841)
* • High-speed WAN interface cards (HWICs)

The following components plug into connectors inside the chassis and are installed and removed only by
opening the chassis:

* • Advanced Integration Module (AIM)
* • Synchronous dynamic RAM (SDRAM) small-outline dual in-line memory module (SODIMM

Summarize the changes that are possible for this router. This information is important to have and consider when planning and designing the network upgrade.
If the router is not at its limit of these features, candidates for upgrading could include:
Flash memory (if larger IOS required)
SDRAM
Slot 1 Ethernet switch 4-port module
Slot 1 WIC-2T – 2 serial interfaces
Slot 1 Other WAN technology DSL/ISDN

Step 4: Clean up
Erase any configurations and reload the router. Disconnect and store the cabling. For PC hosts that are
normally connected to other networks (such as the school LAN or to the Internet), reconnect the appropriate cabling and restore the TCP/IP settings.

Task 3: Reflection
Network device capabilities are continuously developing. Consider the advantages of a modular platform over that of a device with a fixed hardware platform.
Modularitas memfasilitasi kustomisasi perangkat untuk memenuhi kebutuhan jaringan lokal.
Peningkatan dan penggantian modul mengurangi biaya dan waktu dari layanan.
Perangkat Modular menyediakan desain jaringan yang fleksibel dan scalable.
