CompTIA Network+ N10-005

Course Duration: 1 day(s), 00:51:46
Introduction to CompTIA Network+ N10-005
In this introductory Nugget, Keith Barker discusses what will be covered in this Nugget training series and how the training maps to the N10-005 exam objectives. Keith also gives some advice about on how to get the most out of this training series.
Network Concepts 101: OSI vs TCP/IP
In this Nugget, Keith explains how computer networks operate, by using interesting analogies, real world examples and presenting it in a fun and easy to understand manner. In this Nugget you will learn how to describe the "thought process" a computer goes through when preparing to send a message, as well as the steps taken by the computer or server who is receiving the message. This Nugget is the foundation for all of the others. Maps to exam objective 1.1
Network Concepts: Matching up Network Components with Their Correct OSI
Understanding how the real network components we use today, such as network interface cards, addresses, switches and routers, all relate to the OSI model covered in this Nugget. Maps to exam objective 1.2.
NC: IP Addressing Uncut and Uncensored
IP addresses are something that we work with every day on the network, both IP version 4 and 6. In this Nugget, Keith answers the question "Why do we need IP addresses?", and then proceeds to take you on the journey behind the scenes as the world of IP addressing is demystified, one step at a time. Maps to exam objective 1.3
NC: Routing and Switching
Learning what to do, and then doing it, are two of the primary responsibilities of routers and switches. In this Nugget, Keith provides examples of what each do, and gives live demonstrations of the most relevant protocols, including RIP, OSPF and EIGRP for routers, and Spanning Tree Protocol (STP) for switches. Maps to exam objective 1.4
NC: Well-Known Ports
For each popular application layer protocol, (such as HTTP for surfing the Web, DNS to find out what IP address we can use to reach, and SMTP for sending email), there is a "Well-Known Port" that is associated with each of these protocols. In this Nugget, Keith discusses the reason for these ports, demonstrates them in action and takes you behind the scenes with a protocol analyzer to reinforce what you have learned. Maps to exam objective 1.5
NC: The Functions of Common Protocols
So what does ARP do, and how does my computer know which IP address it should send a packet to when accessing a Google server? These are just a few of the questions that are answered in this Nugget as Keith reviews several of the protocols in the TCP/IP protocol suite, and introduces you to a few new ones as well. To complete this fun Nugget, Keith provides a demonstration of a computer that joins the network and accesses a Web server, and then we go behind the scenes with a protocol analyzer to confirm the details of how DHCP, ARP, DNS and HTTP were all functioning to make the Web request possible. Maps to exam objective 1.6
NC: Digging into the Details of DNS
How do we find the phone number of a friend? Usually we will look at some type of online database or phone book, that can provide the phone number based on their name. How does a computer find the IP address of a Web server? As we learned in a previous Nugget, the computer will use the Domain Name System (DNS). On the surface, it looks fairly simple: The computer asks a DNS server, and the DNS server replies, but behind the scenes, there are thousands of servers cooperating together to make this all possible. In this Nugget, Keith provides a sneak peak behind the scenes a the inner workings of the Domain Name System, as well as some tools you can use to verify and troubleshoot DNS. Maps to exam objective 1.7
NC: Using a Method When Troubleshooting
When the network goes "bump" in the night, and users have lost access, it can be a stressful time for both the users and you, the network technician. By having a method to follow when troubleshooting can give you the edge (and confidence) to ask the right questions, isolate the problem, and get the network up and running. In this Nugget, Keith walks you through using a methodology to do live troubleshooting on network that has been used in class since the first Nugget of this series. Maps to exam objective 1.8
NC: Moving to Virtual
The world is a changing place, and when a new idea comes along that makes sense, and saves money, it usually moves forward. This is the case with virtualization. In the old days, when a company needed a new server, they would buy one physical sever, install the software, and add it to the network. This process usually took weeks. Now, new servers can be brought online in a "virtual" environment, and be up and running in only minutes. In this Nugget, Keith describes the concepts of how virtualization is possible, then he takes you behind the scenes of how it is done with live examples of virtualized Servers, workstations, routers and switches. Maps to exam objective 1.9
Network Installation and Configuration: Routers and Switches Part 1 of 2
Leveraging the fundamentals we learned in the previous Nuggets, it's time to put network pieces together for a functional network. In this Nugget (part 1 of 2), Keith walks you through the configuration of a router including interfaces, routing, access-lists and more. You will also discover the how and why Quality of Service (QoS), Network Address Translation (NAT) and its little friend PAT which are used on today's networks. Maps to exam objective 2.1
NIC: Routers and Switches Part 2 of 2
Implementing switching, correctly, is a key skill for a network technician. In this Nugget, Keith reviews the concepts of VLANs, and dives in deeper to discuss the details implementing them, as well as trunking (802.1q) and VLAN Trunk Protocol (VTP). Join Keith as he discusses Power over Ethernet (PoE), port mirroring and much more. Maps to exam objective 2.1
NIC: The World of Wireless
Wireless networking has become an expected feature in business, at hotels, coffee shops and many homes. As network technicians, we must understand the details of the protocols (the rules) and standards for WiFi to successfully implement a wireless network. In part one of this two-part Nugget, Keith walks you through the standards used in wireless, explains the components and how they inter-operate together. Maps to exam objective 2.2
NIC: Configuring the Wireless Network
In this Nugget, Keith has you join him as he does a "site survey" of existing wireless networks (in real time) to discover the appropriate channel to use for a new wireless transmitter. Armed with that information, you will then join Keith as he walks you through the configuration of a wireless router, and then verifies the configuration by having a wireless client connect to the network. Maps to exam objective 2.2
NIC: Going Deeper into DHCP
DHCP is a fantastic protocol to dynamically assign IP addresses to network devices. DHCP was introduced in an earlier Nugget, and in this Nugget Keith takes you on a deeper discussion of the protocol, including how it is implemented in a larger corporate network scenario. Maps to exam objective 2.3
NIC: Troubleshooting Wireless Networks
Using the airwaves to transmit bits is way cool, but unfortunately, there are several factors that can prevent the wireless network for operating at its best. In this Nugget, Keith shares with you some common challenges that arise in wireless networks, and how to identify and resolve them. Maps to exam objective 2.4
NIC: Troubleshooting common Router and Switch problems
"The network is down!" (A quote from an average user)

Users really only want 2 things: 1) The network to work, and 2) The network to be fast. If either of these aren't the case, they will let you know (and they outnumber us). In times like these, we need to have troubleshooting skills that can confirm a problem, and then like a detective, narrow down the possible causes until we find and correct the problem. In this Nugget, Keith takes you on a journey through a laundry list of things that could go wrong as you and he troubleshoot a live network using both end station troubleshooting tools, (like nslookup) and network tools such as the CLI on a router. Maps to exam objective 2.5
NIC: Plan and Implement a Small Network
Ever have that moment, when they turn to you and ask you to design and implement a network? Now is your chance to do it, alongside Keith, as you both gather requirements from a customer, design the network and identify how all the pieces correctly function together. Maps to exam objective 2.6
Media and Topologies: Fiber and Copper Media
If layer 1 isn't happy, layer 2 isn't happy. (Paraphrased and adapted quote from my father. I think the actual quote was "If mom isn't happy, ain't nobody happy.")
MT: Connector Types
Having the correct media in place is important, but unless that media is correctly connected to the network devices (hosts, routers, switches, etc.) the media won't be of much use. In this video, Keith describes the cable connectors, both fiber and copper types that are commonly used today, and provides some fun ways to remember their names. Maps to exam objective 3.2
MT: Wireless Standards
In a previous Nugget, we learned about the 802.11 wireless standards. In this video Keith reviews wireless standards and takes you even deeper into their characteristics, because of the importance that wireless has in our high speed networks today. Maps to exam objective 3.3
MT: WAN Technologies
Any way you slice it, Wide Area Networks (WANs) are going to require the use of a 3rd party, the service provider. The lightning bolt that represents the WAN can be implemented in many different ways, using a variety of technologies. In this video, Keith demystifies the terms of T1, T3, OC3, etc. and discusses the options regarding WAN services that can be obtained from a provider. Maps to exam objective 3.4
MT: LAN and WAN Topologies
How can a network be a logical bus and a physical star (at the same time) and what is a logical bus anyway? Those are great questions which will be addressed in this video about network topologies. This Nugget includes a brief history lesson regarding the beginnings of Ethernet, and then dives into LAN and WAN topologies that are in use in our production networks today. Maps to objective 3.5
MT: Common Physical Layer Problems
The cabling for the network is like the arteries and veins in the human body. If they stop allowing data to flow through the network, clients and servers won't be able to communicate, which translates to loss of productivity and loss of revenue. In this video Keith talks with you about several of the very common mistakes and issues that arise with physical cabling, as well as some tips to avoid those problems. Maps to objective 3.6
MT: Comparing LAN technologies
Acronyms are in heavy use on the network, and the terms used for cabling are no exception. This video will demystify the terms used for many of the common cable types, as well as compare the throughput and distances supported by them. In this video, Keith reinforces your foundation of how the network operates, and then adds to that some new content including an explanation and demonstration of bonding 2 or more Ethernet connections together to create a single larger Ether-channel. Maps to objective 3.7
MT: Describing the Cable Plant
This plant requires no water to grow. :) By being organized, with a plan and structure for our cables, racks, routers, etc., we can expand our network and keep our sanity at the same time. In this video, Keith explains and discusses wiring distribution terms such as IDF, MDF, Demarcation Point, and many more. This is an important Nugget, as you are likely to hear these terms on a regular basis when working on a corporate network. Maps to objective 3.8
NM: Network Appliances
A Network Appliance is a dedicated box (a server) that performs a specific function in the network. In this video, Keith provides examples of how a network appliance can be used to address a need on a network. Load balancing, VPN Concentrators, Proxy Servers, Firewalls and more are explained in this video. Maps to objective 4.1
NM: Hardware Tools for Troubleshooting
Cables look so innocent from the outside, but can have all sorts of problems on the inside, such as open connections, shorts, incorrect pairs, etc. In this video, Keith takes you on a journey through the world of specialized hardware tools: Cable Testers, Toner Probes, TDR/OTDRs and many others, to discuss with you how and when those tools can be used to troubleshoot physical cabling issues. Maps to objective 4.2
NM: Software Tools for Troubleshooting
Sometimes, the correct tool to verify IP connectivity or DNS functionality, is right in front of us, as a program that is pre-installed on a workstation. In this Video, we will re-visit some of our old friends: Tracert, Nslookup, Ping and IPconfig. Keith will also introduce and demo some new software utilities including DIG, Netstat, remote control software and more. Maps to objective 4.3
NM: Analyze Network Traffic
How do you know? Specifically, how do we find out what is really happening on our networks? The answer is simple if we know where to look. In this video, Keith explains where to look and demonstrates how to discover what is happening on the network. Tools discussed in this video include SNMP, Syslog, Protocol Analyzers and more in the pursuit of discovering the details about the traffic that is coursing through the veins of our networks. Maps to objective 4.4
NM: Documentation for Survival
There are many details regarding today's high speed networks, in fact too many to rely on memory for everything. Documenting is key to survival, and good documentation will allow us to troubleshoot faster, bring up new networks more easily, and have more peace of mind. In this video, Keith discusses with you the key elements that every network should have documented and why documented baselines are important for us today. Maps to objective 4.5
NM: Network Optimization
It was early in the morning, and the network was quiet, too quiet. Then all of a sudden: WHAM! Millions of packets were sent from hundreds of computers, all at the same time when all the users were trying to watch the live video from the Chief Executive Officer (CEO) talking about the quarterly earnings of the company. Unfortunately, the network didn't have the capacity to support all the traffic on it, so quality suffered and the users were upset. How could this be avoided? The answer is network optimization through implementing Quality of Service (QoS). In this video Keith talks with you about the types of network traffic that should be prioritized, and the mechanisms to accomplish that. Maps to objective 4.6
NS: Securing Network Traffic
The network routers and switches do a fantastic job of moving data at a high rate of speed, and perhaps they do too good of a job. By default, the network devices forward traffic regardless of the source, destination or protocol being used. In a production network, there is some traffic that should not be forwarded by the router at all, while other traffic should encrypted for protection before it is forwarded. In this video, Keith explains and demonstrates Access Control Lists (ACLs), VPN Tunnels using IPsec, and other technical controls we can use to secure the traffic on our networks. Maps to exam objective 5.2
NS: Security for Wireless
In the video, we review the need for a site survey, the right type of antennas to make sure we have the wireless coverage we need, and that we are avoiding Radio Frequency Interference (RFI). Once the basics are in place, securing the wireless network is important to avoid eavesdroppers listening in, or gaining unauthorized network access. In this video Keith discusses and demonstrates best practices for securing the wireless network including the idea of MAC address filtering at the access point. Maps to objective 5.1
NS: User Authentication
Until we know "who" a person is, its tricky to provide that user with their own personal set of permissions and access on the network. Authentication (identifying who the user is) is a critical first step in securing the network. In this video, Keith provides you a guided tour of user authentication methods, including Kerberos, AAA, multi-factor authentication and more. Maps to exam objective 5.3
NS: Threats and Vulnerabilities
It is not a matter of "if" our network is attacked, but rather a question of "when". Attack tools readily available, and simple to use. Protecting our network can best be done when we understand where the weak areas are, and what the likely attacks will be. In this video, Keith discusses many of the common attacks as well as the counter measures that we can put in place to limit the effectiveness of those attacks against our network. Maps to exam objective 5.4
NS: Firewalls
A firewall in a racecar (between the engine and the driver) is meant to protect one area from the other. In computer networks, a firewall has same responsibilities. In this video, Keith explains the security attitude that firewalls initially take and how "stateful filtering" is use by industrial strength firewalls today. You and Keith will also implement a firewall, beginning with its default configuration, and ending with a fully functional firewall between the inside users and the outside Internet. Maps to objective 5.5
NS: Security Appliances
When a computer is acting as a server, it will respond to connection request on the applications well known ports (HTTP = 80, SSH = 22, etc). An attacker who wants to discover what services are available on devices in your network can send a connection request to thousands of port numbers (1-65000 as an example) of a specific host, and see which ports are "open" or listening. This is referred to as a port scan. In this video, Keith will demonstrate one of the more popular scanners, and discuss with you detection and prevention mechanisms that we can use to prevent an unauthorized scan of your network. Maps to objective 5.6

00:00:18 - with networking, it was exciting, and I loved it.
00:00:21 - Now, here the 21st Century, computer networks are faster,
00:00:26 - and they're still very, very exciting, and I still love it.
00:00:29 - And as I think back to those days, the early days, I didn't
00:00:33 - learn all the stuff I learned on my own.
00:00:35 - I had some amazing mentors, people that I will be
00:00:38 - eternally grateful to, that took me aside and said this is
00:00:42 - how this works and this is how that works.

00:01:16 - Secondly, maybe you've been in the field for a while.
00:01:19 - Maybe you've been at the help desk, or you've been a server
00:01:22 - administrator, and you'd like to branch off a little further
00:01:26 - into the world of network technician, maybe be a network
00:01:29 - designer or a network trouble shooter, maybe get a Cisco
00:01:32 - certifications or Juniper certification
00:01:34 - or some other vendor.
00:01:36 - This also is for you.
00:01:38 - If you have some of those holes in your knowledge you
00:01:40 - need filled up, some gaps that you'd like to have better
00:01:43 - understanding for, this Network Plus series will help
00:01:46 - assist you in filling those gaps and making you confident
00:01:49 - and providing you that rock solid foundation that you're
00:01:53 - going to need and want to be successful in your career.
00:01:57 - The other two categories, one would be
00:02:00 - management of some type.
00:02:02 - If you're a manager or owner of a small business, and you
00:02:05 - have technicians or individuals that work under
00:02:07 - you, you definitely want to make sure you have a basic
00:02:10 - foundation of knowledge so you can understand when they're
00:02:13 - talking to you.
00:02:14 - And when they propose something, you can ask better
00:02:17 - questions, and if you're purchasing products from
00:02:20 - vendors, you can have better questions and make better
00:02:22 - judges for them.
00:02:23 - And the last category would be somebody who just likes to
00:02:26 - have a good time.
00:02:27 - I have a great time as I talk with you in
00:02:30 - every single Nugget.
00:02:32 - So if you just want to have a good time, you can pick
00:02:34 - virtually any of the Nuggets in this series, turn it on,
00:02:38 - and you or I are off to the races to
00:02:40 - have a fantastic time.
00:02:41 - So what exactly is covered in the new, latest, greatest
00:02:45 - Network Plus, which is what we're talking about?
00:02:47 - And that is a fantastic question, and to answer that,
00:02:51 - I would have us go to a website, and here's the
00:02:53 - website I'd have us go to.

00:03:42 - expected to be learned by someone who is Network Plus
00:03:46 - certified, someone who's demonstrated the skills and
00:03:48 - ability that the Network Plus certification is calling for.
00:03:52 - So here's the five major domains of what they're going
00:03:54 - to be asking about and making sure that you're comfortable
00:03:57 - with, and then it has details on every single one, starting
00:04:00 - with OSI reference model.
00:04:02 - This is the objectives 1.1, 1.2, 1.3 for IP addressing.
00:04:08 - And what I've done in the Nugget series is I've followed
00:04:11 - the exam objectives, so I've made it logical so you can
00:04:16 - jump into this network training and understand
00:04:18 - everything as we go together through it.
00:04:20 - And it also follows the blueprint.
00:04:23 - So if you wanted to say, you know what, Keith, I want to
00:04:25 - focus on IP addressing.
00:04:26 - It's always confused me.
00:04:27 - You have the IP address is 32 bits.
00:04:29 - There's a mask involved.
00:04:30 - There's subnets.
00:04:31 - How does all that work?
00:04:32 - You can jump right to 1.3 in the Nugget
00:04:35 - series and go at it.
00:04:37 - Now, as a homework assignment, get this document from
00:04:40 - and make sure you have it so you can reference
00:04:43 - if you need to.
00:04:44 - So we're going to follow the blueprint from
00:04:46 - CompTIA step by step.
00:04:48 - We've organize the actual Nuggets that way.
00:04:50 - And as we continue our journey through the world of
00:04:53 - networking together, you and I will discover how IP
00:04:56 - addressing works, how the TCP/IP protocols stack
00:04:59 - compares to the OSI reference model, what is a virtual
00:05:03 - private network, a VPN, what's a VLAN, how does IPsec versus
00:05:08 - SSL compare to each other, what's the software and
00:05:11 - hardware involved, the world of virtualization, wireless,
00:05:15 - and much, much more.
00:05:17 - So let's look focus, for a moment, on how you can get the
00:05:19 - absolute most out of this series and optimize your time
00:05:23 - because I realize time is a critical thing.
00:05:25 - The first thing I'd do is I would allocate the time to go
00:05:29 - ahead and go through the Nuggets.
00:05:30 - It's been scientifically proven that if you're not
00:05:33 - listening to a Nugget, you are very unlikely to learn from
00:05:37 - that specific Nugget.
00:05:38 - Are you with me?
00:05:39 - So make a time that you and I can be together to go through
00:05:43 - the basic concepts and discuss and demonstrate the
00:05:47 - technologies as we learn them together.
00:05:49 - Because I'm going to be demoing virtually everything
00:05:51 - that we talk about to reinforce those concepts.
00:05:55 - The second thing I would have you do is I would have
00:05:57 - you do hands on.
00:06:00 - Hands on practice is one of the best ways
00:06:03 - to reinforce a concept.
00:06:04 - Now, what if you don't have a whole rack of equipment?
00:06:07 - That is not a problem because what you do have is you have,
00:06:10 - very likely, a Windows PC or a Macintosh or a
00:06:15 - Linux box of some type.
00:06:17 - Regardless of which one of those three that you primarily
00:06:20 - use, there's a lot of hands on that we can do right at the
00:06:23 - command line of those operating systems, and I will
00:06:26 - walk you through step by step.
00:06:28 - So for example, if we said, hey, how do I find out what
00:06:30 - the IP address is, we don't have to wait.
00:06:33 - If I say go ahead and launch ipconfig right now from a
00:06:36 - command line, you can do it right then with me.
00:06:39 - We can verify the results.
00:06:40 - You can pause me if you need to, and we can continue on.
00:06:44 - Second thing--
00:06:45 - or actually third thing.
00:06:46 - There's one, there's two, there's three.
00:06:48 - The third thing is teach others.
00:06:50 - What do you mean, Keith, teach others?
00:06:53 - Well, what I would strongly recommend you do is I would
00:06:56 - recommend you keep notes.
00:06:57 - So as you and I are discussing whatever the topic is for the
00:07:00 - day-- let's say it's Tuesday, and you joined me for the
00:07:03 - world of switching or routing or access
00:07:07 - control lists or IPv6.
00:07:08 - Whatever it happens to be in our Nugget series together,
00:07:11 - I'd like you to take notes.
00:07:13 - So just on a spiral notebook, make notes of what we talked
00:07:15 - about, and then I'd like you to teach others.
00:07:18 - That is a fantastic way to increase your knowledge.
00:07:21 - I find, personally, that if I teach somebody else the
00:07:25 - content, or try to teach somebody else the content,
00:07:28 - that's the moment I realize I need to revisit this.
00:07:31 - I need to revisit this and refresh my knowledge, or I
00:07:34 - teach it in such a way that I think, you know what, I
00:07:36 - actually get this.
00:07:38 - And the last part is I'd ask you to commit.
00:07:42 - I'd like you to commit to a date when you're going to take
00:07:45 - your certification exam.
00:07:46 - Maybe it's two months out.
00:07:48 - Maybe it's three months out.
00:07:50 - But here's what you're going to do.
00:07:51 - Go ahead and look at your calendar, find out what life
00:07:54 - commitments you have, and then take a look at the videos, how
00:07:58 - long they are and how many there are.
00:07:59 - There's a boatload of them, and they're all great.
00:08:01 - And plan on, every day or maybe a couple hours a day,
00:08:08 - going through the videos so that you can finish all of
00:08:11 - them and have time to review your notes and go back to
00:08:15 - maybe one or two that you want to revisit before you go take
00:08:18 - your certification.
00:08:19 - So commit to a date, and here's what I learned.
00:08:22 - Somebody wiser than me told me this.
00:08:25 - They said, Keith, if you don't commit to something in public,
00:08:29 - you're not really serious about it.
00:08:30 - I said, no, I'm serious.
00:08:32 - I really want to do this.
00:08:33 - And she said to me, well, why don't you put
00:08:35 - it on Facebook then?
00:08:36 - Why don't you tell the world what you're going to do, and
00:08:39 - then if you don't do it, you'll have the world to go
00:08:42 - ahead and face.
00:08:43 - I thought, wow, that's like negative pressure, and she
00:08:47 - said, yes, it is.
00:08:49 - So what I'm asking you do is I'm asking you commit to a
00:08:51 - date for Network Plus, and I'd like to share
00:08:54 - that date with someone.
00:08:55 - It doesn't have to me.
00:08:56 - If you want to, you can go up by a Facebook page.
00:08:59 - It's called Keith Barker Networking, and you can go up
00:09:02 - there and say, Keith, I'm committed to my Network Plus
00:09:04 - exam in this month of this year.
00:09:07 - You don't have to give me a specific date.
00:09:08 - You can do ahead and just give me a month, and that way I can
00:09:11 - look at it, and I can follow up.
00:09:14 - And here's why that works.
00:09:16 - Having the pressure-- people often do things
00:09:18 - for one of two reasons.
00:09:20 - Number one, they want to get some benefit out of it, or
00:09:23 - they want to avoid pain.
00:09:25 - So they're going for the positive
00:09:26 - or avoiding a negative.
00:09:28 - So individuals who accomplish their goals, statistically,
00:09:32 - get there because of one of three things.
00:09:35 - Number one, they think how great it's going to be once
00:09:37 - they accomplish it.
00:09:39 - And just think, when you look back on this course that you
00:09:41 - went through with me, and it's like 10 years from now, and
00:09:45 - you're looking back with fond memories of how it all started
00:09:48 - and where you're at now, you're going to be amazed, and
00:09:50 - it's going to be great.
00:09:51 - So number one, you can imagine how fantastic it's going to be
00:09:55 - to accomplish it.
00:09:57 - Number two, which isn't as good, you can think about the
00:10:00 - negative impact of doing nothing will
00:10:03 - have on your life.
00:10:05 - So you can think of, oh, my gosh, if I just sit here, I'm
00:10:08 - going to be at the same job doing the same thing.
00:10:10 - I'm not going to progress unless I take some action, and
00:10:13 - that can be a motivator for some.
00:10:15 - And the third one that, actually, I use on a daily
00:10:18 - basis, is I just don't think about it.
00:10:22 - What do you mean, Keith, you don't think about it?
00:10:24 - Well, let's say I've committed to exercise three times a
00:10:27 - week, which I have, and I post it on Facebook.
00:10:32 - So I've committed exercise three times a week, and when
00:10:35 - it is my time to exercise--
00:10:36 - or I'm looking at the week, and sometimes it's a little
00:10:38 - flexible, but I get three a week.
00:10:40 - And at what if I don't feel like exercising?
00:10:42 - This happens all the time, just to let you know.
00:10:45 - I think, well, you know what, I've been
00:10:47 - working hard all day.
00:10:48 - I really don't feel like exercising.
00:10:50 - I just don't think about it.
00:10:51 - I say you know what, I need exercise.
00:10:53 - I'm just going to do it.
00:10:54 - And then once I start, guess what, I am totally good.
00:10:58 - I'm like five or six minutes into the exercise, I'm
00:11:01 - thinking, OK, I'm here, and I'm going to finish this
00:11:03 - 25-minute spin or whatever it is, and I finish it.
00:11:06 - So if you commit to the time and you say, you know what,
00:11:10 - I'm not going to think about whether or not
00:11:11 - I want to do it.
00:11:12 - I'm just going to go ahead and do it.
00:11:13 - Once you get in, and you're starting to talk with me in
00:11:16 - the video series, you'll be absolutely fine.
00:11:18 - So three strategies for getting stuff done.
00:11:22 - One, think how great it's going to be.
00:11:23 - Number two, think about how bad it's going
00:11:26 - to be if you don't.
00:11:27 - And third is not think about at all.
00:11:30 - Set your goals and spend the time when you say you're going
00:11:33 - to do it on studying.
00:11:36 - One last item I'd like to encourage you to do, and that
00:11:38 - would be to take the courses, take the Nuggets in order.
00:11:41 - You can always go back to any specific Nugget you want for
00:11:44 - reinforcement, but here's why the order's important.
00:11:47 - We're going to start right here at Zero, and we're going
00:11:50 - to go up here to Hero, and we're going
00:11:53 - to do in that order.
00:11:54 - And as we go, we're going to build our knowledge.
00:11:56 - So for example, here, we might learn about the OSI model.
00:11:59 - Here we might learn about the IP and IP addressing.
00:12:02 - Here, we might start using protocol analyzers to actually
00:12:07 - take a look.
00:12:08 - And so if we're looking at a protocol analyzer, looking at
00:12:10 - IP addresses, and maybe looking at TCP or UDP segments
00:12:15 - at layer four, it's implied that we've already taken a
00:12:19 - look at the basics so we can leverage the advanced
00:12:21 - information, so I would take them in order.
00:12:24 - You don't have to, but that's my strong recommendation is to
00:12:27 - start with 1.1 and work your all the way to the end, 5.X.
00:12:32 - So what exactly have we talked about in this introduction to
00:12:36 - the Network Plus series?
00:12:37 - Number one, the video series is made for you.
00:12:40 - Every single Nugget that I put together, I did as if you were
00:12:45 - sitting right next to me.
00:12:46 - We're just sitting at a couple computers.
00:12:48 - We're going through the technology, demonstrating
00:12:51 - everything as we go, to make sure that you and I completely
00:12:54 - get it, that we understand each of the concepts as we
00:12:57 - build upon the previous concept.
00:12:59 - What's covered?
00:13:00 - Everything, everything in the Network Plus official
00:13:04 - objectives is covered, and I threw in some additional
00:13:07 - tidbits here and there that I thought would be extremely
00:13:09 - valuable and useful for the real world, as well, that
00:13:12 - could increase and reinforce those concepts.
00:13:15 - And how do I get the most of the series?
00:13:17 - It really boils down to, number one, finding the time
00:13:21 - to go through them.
00:13:22 - Take notes, teach others, and commit.
00:13:25 - If you commit publicly, you'll have more pressure and
00:13:28 - motivation to get it done, and I'll tell you what, those
00:13:31 - changes can change your life.
00:13:33 - It's not just a matter of learning
00:13:35 - some facts and details.
00:13:36 - We're talking about changing people's
00:13:38 - lives, and I mean you.
00:13:40 - I know this from my own personal experience.
00:13:43 - I have a couple CCIEs with Cisco, and I have Juniper
00:13:46 - certifications, and I have some HP certifications, and
00:13:49 - [INAUDIBLE], and et cetera, et cetera.
00:13:50 - And every time I apply myself just to steady constant steps
00:13:55 - of learning and improving my skills, it has always, always
00:13:59 - paid off, and I know it'll do the same for you.
00:14:01 - I am super excited about joining you in every single
00:14:05 - one of these Nuggets.
00:14:07 - I hope this is has been informative for you, and I'd
00:14:09 - like to thank you for viewing.
