CCNA1-5 Chapter 1

Certification Exam – Student Feedback

Mike I wanted to let you know, I passed the CCNA 640-802 test today, with a 934/1000 (it would have been higher, but see the

commentary below)

Lessons Learned

• You can NEVER go back, if you skip a question, it's wrong.

• Passing Grade is 825/1000

• Simulations are worth around 50 points ( I know this because I skipped it, and realized too late, DOH!)

• Read a question fully, if it says select 3, and you choose 2, it will not warn you on some questions.

• Know your routing, and routing behaviour, there will be some tricky ones on the test for sure

• Things that will be on the Exam. STP, Access-Lists, and EIGRP

• Know your command-line

• Tab does not finish commands on the test, ? still works

• You must have the know how to use command line to get the answers you need ie, show vtp status to get the ip of the vtpserver, and use show cdp neighbor detail to get its name

• Do your packet tracer labs, or don't bother with the exam, there are many of "How do we solve this questions"

Mike I just thought you should know I found the test easy, but it was the hard work on my end, and your mentoring that lead tothe easy test.

One suggestion ok, maybe two, make sure you go over STP and drive home the Root Bridge Election portion more,

Access-lists we need more time to work on those, they are linked to so many things.

Overall, I feel the Cisco coarse was the highlight of the ITP program for me personally because of my IT background, especiallythe WAN section, that shined a light into dark area's of my experience.



CCNA1-6 Chapter 1

Gradebook Weightings

A pass is 70%.You must pass the exam (70%) to pass the course module.

Each module is a prerequisite to the next module.You must prove to Instructor/TA a lab in complete to get credit.



Best Practices

• Complete all work during class time• Work in small teams to complete labs & assessments

• Don’t cheat yourself by copying assessment/exam answers

• For best understanding read the Cisco Academy chapter

• Try to relate networking to a post office. They are similar.

• Use FireFox, as IE has some problems with Cisco website

• This course will focus on researching information more thanmemorizing



Typical Student Challenges

• If Internet Explorer doesn’t work try FireFox • Subnetting (see reference sheet)

• Acronyms – knowing them & what they mean (seehttp://acronymsonline.com/Default.asp)

• Command Line Interface (CLI Command Reference.pdf) • Wrong cabling (straight thru vs cross-over)

• Workload

• Time Management

• The telephone was used for voice and the post officedelivered most of the written communications.

• Video communication was one-way using the television.



CCNA1-19 Chapter 1

Networks – The Early Days

• Early networks were limited to character based information.• Communications between computers was not easy and

required a host (no pun intended) of resources to accomplishthe simplest data transfer.



CCNA1-20 Chapter 1

CCNA1-27 Chapter 1

Networks Supporting The Way We Work

• Business networks evolved to enable the transmission ofmany different types of information services, including e-mail,video, messaging, and telephony.

• Different companies use different types of networks.



CCNA1-28 Chapter 1

Networks Supporting The Way We Work



CCNA1-29 Chapter 1

Networks Supporting The Way We Play

• The entertainment and travel industries have made use of theInternet to provide online gaming, music and moviedownloads, online travel bookings, hotel and car reservationsand much, much more.



CCNA1-30 Chapter 1

Networks Supporting The Way We Play

• Some of the most innovative developments in networktechnology have come from the increasing demand forentertainment.



CCNA1-31 Chapter 1

Communications – What is it?

• Communications can take many forms and occurs in manydifferent environments.

• We establish rules, or protocols, for communicating with eachother:

• Identify the sender and receiver.• Agree on the method.

• Common language.

• Speed and delivery of the message.

• Confirmation that the message was received.

• Communications between individuals is successful if themeaning of the received message is the same as themeaning of the message that was sent.



CCNA1-32 Chapter 1

Communications - Quality

•

For data networks, we use the same basic criteria to judgesuccessful communication.

• However, there are external factors that can affect themessage.

• The quality of the pathway between the sender and therecipient.

• The number of times the message has to change form orbe redirected or re-addressed.

• The number of other messages being transmitted

simultaneously on the communication network.• The amount of time allotted for successful

communication.



CCNA1-33 Chapter 1


•

There are also internal factors that can affect successfulcommunication.

Message Size

MessageComplexity

MessageImportance



CCNA1-34 Chapter 1


•It is also more difficult to deliver a large, bulky packagesuccessfully and without damage than it is to deliver severalsmaller packages.



CCNA1-35 Chapter 1

Network As A Platform

•

All networks have 4 basic elements in common:

Rules (protocols) to govern the handling of the message.

Messages that travel from one device to another.

Medium that is used to interconnect devices and cantransport the messages from one device to another.

Devices on the network that exchange messages.



CCNA1-36 Chapter 1


Rules on a network seem almost endless – but they’re not.

• Other Application Protocols:

• DNS, DHCP, FTP

• Some Other Protocols:

• TCP/IP Protocol Suite, Ethernet, Routing Protocols



CCNA1-37 Chapter 1


Messages take many forms.



CCNA1-38 Chapter 1


Media on a network can be varied.



CCNA1-39 Chapter 1


Devices on a network – Common Symbols



CCNA1-40 Chapter 1

Putting It all Together

1. Converted to Binary.

2. NIC generates signals.

3. Passed among LAN devices.

4. Exit the local area (router).



CCNA1-41 Chapter 1


The many interconnecteddevices worldwide are often

represented by a cloud.

5. Bits are transmitted todevices that interconnectthe networks.



CCNA1-42 Chapter 1


6. Passed among localdevices at the destination.

7. The destination device convertsthe bits into human readable form.

CCNA1-48 Chapter 1

The Architecture of the Internet

•

The term Network Architecture defines… • Technologies that support the infrastructure

• Programmed services and protocols that move themessages across that infrastructure.

• There are 4 basic characteristics for networks in general tomeet user expectations:

• Fault tolerance

• Scalability

• Quality of Service (QoS)• Security




CCNA1-49 Chapter 1


Fault Tolerance




CCNA1-50 Chapter 1


•

Fault Tolerance:• The Internet, in its early inception, was the result of

research funded by the United States Department ofDefense (DoD).

• Fault tolerance was the focus of the initial internetworkdesign.

• Early network researchers looked at the existingcommunication networks, which were primarily for thetransmission of voice traffic, to determine what could bedone to improve the fault tolerance level.




CCNA1-51 Chapter 1

CCNA1-54 Chapter 1


Scalability




CCNA1-55 Chapter 1


•

A good example of scalability is the Tier architecture of theInternet.Tier 2: Pay Tier 1 providers for

connectivity and provideregional service.

Tier 1: ISPs provide nationaland international connections.(Verizon, Sprint, AT&T, NTT,

cable systems, etc.)

Internet

Backbone

Tier 3: Provide service to endusers and are usually connected

through Tier 2 providers.




CCNA1-56 Chapter 1


•

Additional providers can be added relatively easily with nodisruption of current services. THAT is scalability!

CCNA1-64 Chapter 1

IT is not the Network – it IS the users.

•

The IT (Information Technology)department is not the network.

• The network is the users and their:

• Needs• Expectations

• Requirements

• Uses

If IT doesn’t find a way, the

users will!

A Shift in Attitude



CCNA1-65 Chapter 1

A Shift in Attitude

•

The following Old school IT thinkingdoesn’t work any more.

• We don’t support PCs or Apples.

• We can’t allow that application

on our network.• We can’t give them access

on our network.

• We have too much to do already.

• We don’t support that. • You don’t know about networks, so we can’t do that.

• That would breach our security

Technical and Soft Skills



CCNA1-66 Chapter 1

Technical and Soft Skills

•

Networking professionalsneed more knowledge andskills today than ever before.

• Tomorrow’s IT professionalswill need even more skills.

• Just as important, andsometimes even moreimportant, are the soft skills:

• Attitude

• Enthusiasm

• Communications skills

• Professionalism and Ethics
