Cisco CCNA Certification Exam Training: What Is Packet Switching?

Cisco CCNA certification exam training means you need to learn a lot of new terms, and some of them can be a little problematic at first view.
To pass this hard certification exam,you definitely need to understand one term which is packet switching. The first question, of course, is “What is packet switching in the first place?” In today’s Cisco CCNA exam prep tutorial we will learn about this term.

Packets transmitted from “point A” to “point B” all have to arrive at the same destination, but with packet switching, they do not all have to take the same path to get there. If you and I are standing 10 feet apart and I want to throw a rugby ball to you, I’ve got some options. I could bounce the ball off the floor to you, I could throw it directly to you, or I could send it up into the air to you. Packet switching is pretty the same thing – packets will take different paths to get from source to destination, but the result is that all the packets arrive at the destination. Then they are then reassembled to take the form of the original message.

Packet switching may sound a little odd, but this is the most efficient way of transporting the data. Frame Relay is a packet switching technology, as is X.25, and both of these standards are very efficient.

When we have packets that must arrive at the destination in the same order in which they left the source, packet switching is not the best choice. For this situation, we’ll need to use something like circuit switching, and we’ll discuss that in tomorrow’s Cisco CCNA certification training article!

A Glimpse Into IBM Professional Certification

The IBM line of offerings spans across all segments of the IT industry: hardware, software, consulting and IT services. The challenge for the IBM Professional Certification Program is to keep pace with the certification needs across the many professions within all of these segments of the IT industry.

To make the challenge even more interesting in the fast-paced world of IT, business frequently is re-evaluated and reorganized to meet the needs and demands of the rapidly growing IT marketplace. Business models, product lines, services and organizational structures all change to support business growth and customer demand. As a result, skills requirements continue to evolve at a rapid rate, requiring certification to keep pace.

To meet the challenge, IBM provides 18 certification programs under the umbrella of the Professional Certification Program. Each area includes certifications that cross the various roles of IT, including users, administrators, developers, architects and technical and sales professionals.

The programs include new certification offerings based on technology from the IBM Systems and Technology Group and long-established and popular DB2 certifications from the IBM Software Group.

A New Power Requirement

In January, IBM combined the System i and System p product lines, simplifying them and renaming them Power Systems. At the same time, IBM announced a shift in its sales process from a brand-specific focus, with sales professionals who concentrated on System i, System p and Storage, to a client-centric focus with sales teams focusing on the best solution for the client, regardless of brand.

With all these changes and the emergence of Power Systems, a new certification program was needed. Laura Calley, the Power Systems certification program manager in the IBM Systems and Technology Group, was tasked to evaluate the certification portfolios of the former System i and System p, converge them where appropriate and create the new Power Systems certification program.

Calley had experience in revamping certification programs. In 2007, she resized the portfolio of the System i certification exams. Certifications were evaluated, and exams were updated or retired. In addition, plans were put in place with IBM’s Academic Initiative to help college students earn certifications to facilitate them gaining employment in the IT field.

Restructuring for Power

To successfully restructure the new certification program for Power Systems, executives, brand managers and partner-channel management offered input. Test-delivery and tracking methods were evaluated and budgets scrutinized. All of the data was gathered and analyzed.

When the analysis was complete, it was determined that, while the hardware was important, it was the operating system chosen by the customer that reflected the customer’s business and dictated how the hardware operates. Calley began plans to implement the new program by preparing new certifications reflective of the new Power6 generation of processors, with focus on the IBM i V6.1, AIX 6.1 and Linux operating systems. With the design of the new program, existing System i and System p certifications were identified for withdrawal.

To develop the exams, the IBM Power Systems certification program used carefully screened subject matter experts from the customer, partner and IBM sales and technical communities. These IT professionals set the standard of each certification, clarifying the job role of the certification candidate, determining common tasks and evaluating which skill level is required to validate that the test-taker has the skills in question. As experienced volunteers, they keep the certifications grounded in the real world of customers and partners.

The team for the first pair of exams was divided into two groups: Power Systems Sales for the IBM i operating system and Power Systems Sales for AIX and Linux. These teams worked both remotely and in face-to-face sessions over several months, developing the tests that were designed to be reliable measurement instruments, relevant to the Power Systems Sales role for the targeted audience.

The result was two new Power certifications:

* IBM Certified Specialist – Power Systems Sales for IBM i Operating System (Test 973): This certification is for those with experience in sales and sales support roles. The successful candidate has 12 to 18 months of strong product experience. He or she also has experience assessing customer business requirements, utilizing sales tools and resources, presenting solution proposals and managing customer relationships.
* IBM Certified Specialist – Power Systems Sales for AIX and Linux (Test 331): The successful candidate for this certification should have a minimum of six months of hands-on experience selling Power Systems servers, related application software, middleware and services.

Details about these certifications, as well as information regarding promotions and special offers for discount testing, can be found on the Power Systems certification Web site at

Preparation: Key to Success

Preparation for certification is essential. The test — preparation information for each certification is available on the Web site, including road maps, training resources and access linking to the online assessment tests. These online tests provide a means of assessing a candidate’s readiness for taking the certification exam and are available at www.ibt.prometric.com/ibm. These assessment tests are the only method supported by IBM to determine candidate readiness for certification.

More to Come

The next step was to form the Power Systems technical test teams to design and develop the corresponding technical certifications. The teams are putting the finishing touches on the second pair of exams prior to publication.

Another View of IBM Certification

Meanwhile, on the other side of the IT spectrum, IBM has a variety of software certification programs. One is IBM Information Management: Information management provides a means to represent, access, maintain, manage, analyze and integrate data and content across diverse information sources. At the core of Information Management is DB2, a relational database that allows businesses to organize and transform data into actionable information.

DB2 certification has a strong following and has been well-established for several years. Susan Dykman, the certification program manager for IBM Information Management, has crafted a certification portfolio that allows DB2 professionals to customize their certification paths based on job role, specialty area and level of skills advancement. Each industry-recognized IBM DB2 9 certification is designed to validate the in-demand skills in today’s competitive market.

The program begins with an entry-level certification, the IBM Certified Database Associate. After establishing a base knowledge of the fundamentals, the DB2 9 certification portfolio provides a choice of certification paths: On the database administrator (DBA) path, there is a choice between specializing in DB2 9 for Linux, Unix and Windows (LUW), or a specialization in DB2 9 for z/OS. An application developer path also offers a variety of options.

* DB2 9 Associate. Database professionals who have never taken a DB2 9 certification will want to start with the DB2 9 Fundamentals. This certification requires knowledge about areas such as planning, security, database objects, DB2 tables, DB2 data with SQL and data concurrency. The IBM Certified Database Associate for DB2 9 Fundamentals certification is awarded upon successful completion of the single exam (730).
* DB2 Administrator. The next level of skill advancement is database administrator (DBA), and there are a variety of DBA certification opportunities.
* DB2 9 Administrator for LUW. The IBM Certified Database Administrator for DB2 9 for Linux, Unix and Windows certification is recommended for DBAs who have significant experience with DB2 9. The exam for this certification (731) covers areas such as DB2 server management, data placement, database access, DB2 utilities, analyzing DB2 activity, high availability and security.
* Upgrade Exams. DB2 certification offers a fast path for DBAs who already hold certifications for DB2 UDB V8 by passing exams 700 and 701. These DBAs can benefit by taking a short upgrade Exam (736) and bypassing exams 730 and 731 to achieve the IBM Certified Database Administrator for DB2 9 for Linux, Unix and Windows certification. The upgrade exam has 38 questions covering areas such as server management, data placement, XML concepts, analyzing DB2 activity, high availability and security.
* DB2 9 Administrator for z/OS. Successfully completing the exam DB2 9 DBA for z/OS (732) earns the credential of IBM Certified Database Administrator – DB2 9 for z/OS. This certification is designed to validate z/OS skills, including database design and implementation; operation and recovery; security; auditing; performance; and installation, migration and upgrade.

Additionally, the DB2 certification portfolio provides opportunities for advanced-level certification.

* DB2 9 Advanced DBA for LUW. The IBM Certified Advanced Database Administrator for DB2 9 for LUW requires three exams: DB2 9 Family Fundamentals (730); DB2 9 DBA for Linux UNIX and Windows (731)l DB2 9 Advanced Database Administrator for Linux UNIX and Windows (734). The advanced DBA is the lead for the DB2 products on one or more of the following platforms: Linux, Unix (including AIX, HP-UX and Sun Solaris) and Windows. This individual has extensive experience as a DBA and extensive knowledge of DB2 9.
* DB2 9 Application Developer. There also are different options on the application developer career path. IBM Certification Application Developer – DB2 9 is an intermediate- or advanced-level application developer specializing in creating applications that run on any of the DB2 platforms: Linux, Unix (including AIX, HP-UX and Sun Solaris) and Windows, z/OS, s/390 and iSeries. This application developer should be skilled in the areas of data manipulation, XML manipulation, advanced programming, database objects and programming methods and others.

The IBM Certified Solutions Developer – DB2 9.5 SQL Procedure Developer is new to the DB2 9 portfolio. The certification requires exam 735 and is designed to measure the important knowledge, skills and abilities necessary to design, build, test and deploy SQL Procedures, triggers and functions. The certification exam covers areas such as SQL procedural language, DB2 SQL procedures, functions, triggers, advanced SQL features and more.

CCNA: Added value or just another certification?

In this article, I will discuss the Cisco Certified Network Associate (CCNA) certification and the value it provides to both employers and employees.

History
Cisco created the Cisco certifications in late 1998 to give administrators a set of skills and to give prospective employers an authenticated way to measure those skills. Becoming a CCNA can be the initial step of a successful journey toward a new or refreshed, highly rewarding, sustainable career. Although the certifications have a Cisco product twist, passing the Cisco certification exams provide people with a basic understanding of networking, regardless of the brand of routers and switches. This adds value to any IT employee.

The CCNA program was not only created to provide a solid introduction to the Cisco internetworking operating system (IOS) and to Cisco hardware, but also to internetworking in general. This makes it helpful to you in areas not exclusively Cisco-related. It’s hard to say at this point in the certification process, but it’s not unrealistic to imagine that future network managers, even those without Cisco equipment, could easily require Cisco certifications of their job applicants. So, if you make it through the CCNA and are still interested in Cisco and internetworking, you’re headed down a certain path to success.

The test
The first certification in the Cisco certification track is the CCNA. The CCNA consists of one written exam, which can be taken at any Sylvan testing center. The exam takes about two hours at most and is mostly multiple-choice questions, with a couple of fill-in-the-blank ones thrown in for good measure. If you pass this exam (passing score is about 82%), you will be crowned a CCNA. After signing a nondisclosure agreement, you will then receive a certificate in the mail.

To meet the CCNA certification skill level, you must be able to:

* ?· Provide an understanding of the OSI model and hierarchal networking.
* ?· Configure a Cisco router with basic configuration options such as hostnames, passwords, banners, and interface descriptions.
* ?· Understand basic IP routing including IP addressing, subnetting, and configuring Cisco routers with IP addresses.
* ?· Understand basic IPX routing including IPX addressing and configuring Cisco routers with IPX network addresses.
* ?· Describe layer-two technologies.
* ?· Back up a router configuration and IOS.
* ?· Telnet in to multiple routers simultaneously and resolve hostnames with a hosts table.
* ?· Filter a network using Access lists.
* ?· Understand basic WAN topologies such as PPP, HDLC, Frame Relay, and ISDN.

Once you can install and configure Cisco switches and routers in multiprotocol internetworks using LAN and WAN interfaces, you are then ready to get a job! A CCNA should possess the skills to handle the following jobs:

* ?· Help desk engineer
* ?· Field technician
* ?· Level 1 systems engineer

Studying
As you study for the CCNA exam, ita€?s critical that you have some hands-on experience with Cisco routers. If you can get your hands on some Cisco routers and switches, you’re set. But if you can’t, try a router simulation software package such as RouterSim for a Cisco router simulator that provides the hands-on experience youa€?ll need to pass the Cisco certification exams at the fraction of a cost of real Cisco equipment. Study guides are also found to be very helpful in your pursuit of Cisco certifications. There are dozens of such guides available in most any bookstore. My book titled CCNA: Cisco Certified Network Associate Study Guideby Sybex Computer Books is one of the more popular Cisco study guides available.

Exam tips
Many questions on the exam will have answer choices that at first glance look identical, especially the syntax questions! Remember to read through the choices carefully, because a close answer won’t cut it. If you choose an answer in which the commands are in the wrong order or one where there is even one measly character missing, theya€?ll count the question wrong. So to practice, find some practice exam questions (over 500 are in my book or try the Boson practice tests). Read each exam question carefully. Don’t jump to conclusions. Make sure you’re clear on exactly what the question is asking.

Where to take the exam
You may take the exam at any one of the more than 800 Authorized Sylvan Prometric Testing Centers around the world. For the location of a testing center near you, call 800-204-3926. Outside the United States and Canada, contact your local Sylvan Prometric Registration Center. Tell them you want to take CCNA exam number 640-802.

How Do I Earn a Cisco Certification?

Expertise in the application of Cisco hardware and software is established by licensed certification. Since such certifications have become industry-standard, you may be wondering: How do I earn Cisco certification? This article should provide answers.
Valuable Certifications

It has become a standard practice within the computer industry for professionals to earn certificates. Businesses and organizations have general confidence that such certification adds value to their operations. Consequently, earning certification has become important to career advancement.
Cisco Certifications

The prevalence of Cisco Systems equipment within the industry has made this certification increasingly important. These certifications have four levels:

* Entry
* Associate
* Professional
* Expert

There also exist a number of specializations. Examples are:

* Cisco Routing and Switching Solutions Specialist
* Cisco Express Foundation Design Specialist
* Cisco IP Telephony Design Specialist
* Cisco Security Solutions and Design Specialist

General Certification Process

Certification is achieved by a combination of coursework, hands-on lab work and examination. Once earned, a certificate is valid for three years. It may be renewed by retaking the exam for that certificate or taking a higher level exam. Cisco examinations are administered by Pearson VUE, www.vue.com.
Sample Certification Process

The most basic Cisco certification is that of Cisco Certified Entry Networking Technician. The curriculum for CCENT does not cover advanced voice, wireless and security issues. It does cover all the skills for switching, routing and addressing needed to establish a small office network.

Achievement of the CCENT certificate requires five days of virtual pre-training, 40 hours of lab work and five days of class. The exam is titled Interconnecting Cisco Networking Devices Part One (ICND1). Cost for the exam is presently $125.00.

The ICND1 course and exam may be followed by ICND2. This leads to certification at the next level, the more well-known Cisco Certified Network Associate designation (CCNA). Some licensed providers offer a popular boot camp approach which provides combined training and a composite exam (CCNA 640-802), leading immediately to the CCNA certification.

Cisco 640-802 CCNA And CCENT Certification: RAM, ROM, NVRAM, Flash, And The Boot Process

An important part of your Cisco CCENT and 640-802 CCNA certification studies is learning the differences between RAM, ROM, NVRAM, and Flash memory. Learn these vital differences from Chris Bryant, CCIE #12933.

An important part of your Cisco CCENT and CCNA certification studies is learning the differences between RAM, ROM, NVRAM, and Flash memory. You better know the differences when it comes to working in real-life networks as well, because vital Cisco files are found in these memory types – and since some of these files are lost on a router reload and some are not, we better know which is which!

The memory types and functions discussed in this section are the same for routers and switches, but to keep from saying “routers and switches” 500 times, I’ll just say “routers”.

Configuring the routers is a lot of fun, but we’ve got to know what’s going on inside the router, too! Cisco routers have four different kinds of memory, and while some of the names are similar, their purpose is totally different.

The contents of some of these memory types is kept when the router is reloaded, and others are lost on a reload. We better know which is which!

It’s a fair bet that these topics will come up on your CCENT and CCNA exams, and this is also information you’ve got to know to be a real network admin. Let’s examine these four memory types closely and see what each one does!

ROM: Read-Only Memory. ROM stores the router’s bootstrap startup program, operating system software, and power-on diagnostic test programs (POST).

Flash Memory: Generally referred to simply as “flash”, the IOS images are held here. Flash is erasable and reprogrammable ROM. Flash memory content is retained by the router on reload.

RAM: Random-Access Memory. Stores operational information such as routing tables and the running configuration file. RAM contents are lost when the router is powered down or reloaded. By default, routers look here first for an Internetwork Operating System (IOS) file during boot.

NVRAM: Non-volatile RAM. NVRAM holds the router’s startup configuration file. NVRAM contents are not lost when the router is powered down or reloaded.

Some important comparisons:

RAM contents are lost on reload, where NVRAM and Flash contents are not.

NVRAM holds the startup configuration file, where RAM holds the running configuration file.

Let’s take a look at the boot process of a Cisco router, and then talk about the dreaded Setup Mode!

The Router Boot Process

When a Cisco router powers up, it first runs a series of POSTs (Power-On Self Test). A POST is a series of diagnostic tests designed to verify the basic operation of the network interfaces, memory, and the CPU.

Depending on the model or router of switch you’re using, you can actually see some of these tests being passed. Here, I’ve reloaded a Cisco 2950 switch, and you can see some of the POSTs being run and passed at the very beginning of the bootup process.

Initializing flashfs…

flashfs[1]: 79 files, 3 directories

flashfs[1]: 0 orphaned files, 0 orphaned directori

flashfs[1]: Total bytes: 7741440

flashfs[1]: Bytes used: 5980672

flashfs[1]: Bytes available: 1760768

flashfs[1]: flashfs fsck took 7 seconds.

flashfs[1]: Initialization complete.

Done initializing flashfs.

POST: System Board Test : Passed

POST: Ethernet Controller Test : Passed

ASIC Initialization Passed

POST: FRONT-END LOOPBACK TEST : Passed

POSTs are particularly effective at detecting major problems early in the boot process, such as a broken fan. If the POST detects such a problem (usually called an “environmental factor”) that would cause the router or switch to overheat after booting, the POST will fail, give you a clear message as to why the POST failed, and will then stop the boot process.

But let’s speak positively here!

After the router passes the POST, it looks for a source from which to load a valid Internetwork Operating System (IOS). The router has three sources from which it can load an IOS image, and it’s a good idea to know these sources and the order in which the router will look in each for the IOS image:

1. Flash memory (the default).

2. A TFTP server. (Trivial File Transfer Protocol)

3. Read-Only Memory (ROM)

To change that order, a change must be made to the configuration register, and we’ll talk about that later in the course. It’s similar to the Microsoft Registry in that you should never change this value unless you are sure of the result.

Once the IOS is found, the router looks for a valid startup configuration file. By default, the router will look for the startup configuration file in Non-volatile RAM (NVRAM).

If no valid startup configuration file is found, the router enters setup mode, where the router runs the system configuration dialogue, a series of questions involving basic router setup. We’ll take a look at Setup Mode in the next installment of my exclusive 640-802 CCNA and CCENT certification exam tutorial series

Cisco Certification: How To Build Your Own Home Lab

Two routers really are required to see if anything works. If you have a very limited budget, you can receive value from only purchasing a single router over working with a simulator. However, you will not be able to see the main thing we are trying to accomplish. The propagation of route tables!

The only way you can see if your configurations work, is to have at least two routers. Therefore, I strongly recommend that you purchase a dual router kit that comes with all the accessories you need. Otherwise you can spend days trying to find all the little extra pieces you need to get your lab up and running.

Do I need a switch?

Well, it is nice to have. However, with only about 2 questions on the test dedicated to ?hands on? switch knowledge, if you have to skimp on something, skimp on the switch.

What routers and switches should I buy?

Choices, choices, choices! Which 2500/2600 router do I pick? I will list some pros and cons of each router below, along with current prices (note that prices are generally lower if you buy a dual router kit instead of a single router). Please note that prices are approximations.

1) Cisco 2501 Router with 16 MB Flash/16MB DRAM $94.99. The cheapest introduction router, and it can support a vast majority of the commands that you will need to learn for your CCNA test. All 2500 routers that we will discuss come with a minimum of two serial ports and an Ethernet port.

You will need to add a transceiver to this unit to convert the Ethernet AUI port to an RJ-45 style Ethernet port.

2) Cisco 2503 Router with 16 MB Flash/16MB DRAM $119.99. This is the same as a Cisco 2501, except it adds an ISDN port so you can complete all your ISDN commands for the CCNA test. You will need to add a transceiver to convert the Ethernet AUI port to an RJ-45 style Ethernet port.

3) Cisco 2505/2507 with 16 MB Flash/16MB DRAM $109.99. The same as a Cisco 2501 except it has a built-in 8 or 16 port hub so you do not have to purchase a transceiver.

4) Cisco 2514 Router with 16 MB Flash/16MB DRAM $149.99. This router is the same as a Cisco 2501 except instead of one Ethernet port you have two. You may ask, what is the big deal? Well, you can use this as your Cable Modem/DSL Modem router. Now you can test your ability to setup a firewall and router in a live environment on the Internet. Lots of fun! You will need to add two transceivers to convert the Ethernet AUI ports to an RJ-45 style Ethernet ports.

5) Cisco 2520 Router with 16 MB Flash/16MB DRAM $119.99. This is the same as a 2503 but it also adds two more serial ports so you can use this as a frame relay switch later in your CCNA studies. It costs the same as a 2503, so this is a great money saving tip.

6) Cisco 2612 Router with 32 DRAM and 8 MB Flash $199.99. This is a modular router unlike any of the 2500 series routers. So the big benefit of this is you can buy extra modules to add functionality such as more serial ports, ISDN ports, Ethernet ports, WICs and such. However, due to the flexibility you will pay a bit more. One day it is a frame relay switch, the next it is your ISDN router. In the long run it will be cheaper than purchasing a bunch of dedicated routers for each

discipline you want to learn.

7) Cisco 1912 or 1924 Switch with Enterprise Software $109.99. This is a good low cost switch. The only drawback is it is a 10 MB switch except for the two 100 MB uplink ports. Not a big deal since you have 10 MB routers.

Cisco 2912 or 2924 Switch with Enterprise Software $249.99. This switch will run all the current commands needed for the test and is a full 100 MB switch.

And should you desire to sell your lab after you complete your certification, you can either negotiate a price with the vendor who sold it to you, or you can sell it yourself on ebay. It?s my experience that 95% of candidates who earn their CCNA go on to pursue their CCNP within one year, though, so don?t sell it too quickly.

In the end, you spend only a few hundred dollars, and you gain invaluable experience and knowledge that will help you both in your certification quest and your job performance. Having worked my way from the CCNA to the CCIE, I can tell you that you will learn much more from actually configuring and cabling your own equipment than you ever will from any simulation of the real thing.
