A Networking Academy delivers web-based content, online assessment, student performance tracking, and hands-on labs to prepare students for industry-standard certifications.The CCNA curriculum includes four courses oriented around the topics on the Cisco Certified Network Associate (CCNA) certification. LAN Switching and Wireless, CCNA Exploration Labs and Study Guide is a supplement to your classroom and laboratory experience with the Cisco Networking Academy. In order to be successful on the exam and achieve your CCNA certification, you should do everything in your power to arm yourself with a variety of tools and training materials to support your learn ing efforts. This Labs and Study Guide is just such a collection of tools.Used to its fullest extent, it will help you gain the knowledge and practice the skills associated with the content area of the CCNA Exploration LAN Switching and Wireless course. Specifically, this book will help you work on these main areas: à ¦ LAN design principles and concepts à ¦ Ethernet operation with switches à ¦ Basic switch configuration and security à ¦ VLAN concepts and configuration à ¦ VTP concepts and configuration à ¦ STP, RSTP, and rapid PVST+ concepts and configuration à ¦ Inter-VLAN routing concepts and configuration à ¦ LAN wireless concepts and security issues LAN wireless configuration using Linksys WRT300N routers à ¦ Troubleshooting LAN switching and wireless configurations Labs and Study Guides similar to this one are also available for the other three courses: Network Fundamentals, CCNA Exploration Labs and Study Guide, Routing Protocols and Concepts, CCNA Exploration Labs a nd Study Guide, and Accessing the WAN, CCNA Exploration Labs and Study Guide. Audience for This Book This bookââ¬â¢s main audience is anyone taking the CCNA Exploration LAN Switching and Wireless course of the Cisco Networking Academy curriculum.Many Academies use this book as a required tool in the course, while other Academies recommend the Labs and Study Guides as an additional source of study and practice materials. The secondary audiences for this book include people taking CCNA-related classes from professional training organizations. This book can also be used for college- and university-level networking courses, as well as anyone wanting to gain a detailed understanding of basic switching and wireless technologies. 00_2028_fm. qxp xviii 4/3/08 5:08 PM Page xviii LAN Switching and Wireless, CCNA Exploration Labs and Study Guide Goals and MethodsThe most important goal of this book is to help you pass the CCNA exam (640-802). Passing this foundation exam means that you not only have the required knowledge of the technologies covered by the exam, but that you can plan, design, implement, operate, and troubleshoot these technologies. In other words, these exams are rigorously application based. You can view the exam topics any time at http://www. cisco. com/go/certifications. The topics are divided into eight categories: à ¦ Describe how a network works à ¦ Configure, verify, and troubleshoot a switch with VLANs and inter-switch communications à ¦Implement an IP addressing scheme and IP services to meet network requirements in a medium-sized enterprise branch office network à ¦ Configure, verify, and troubleshoot basic router operation and routing on Cisco devices à ¦ Explain and select the appropriate administrative tasks required for a WLAN à ¦ Identify security threats to a network and describe general methods to mitigate those threats à ¦ Implement, verify, and troubleshoot NAT and ACLs in a medium-sized enterprise branch office network à ¦ Implement and verify WAN links The LAN Switching and Wireless course focuses on the second, fifth, and sixth bullets.The Study Guide portion of each chapter offers exercises that help you learn the LAN switching and wireless concepts as well as the configurations crucial to your success as a CCNA exam candidate. Each chapter is slightly different and includes some or all of the following types of exercises: à ¦ à ¦ Skill-building activities and scenarios à ¦ Configuration scenarios à ¦ Concept questions à ¦ Packet Tracer Activity Vocabulary matching and completion Internet research In the configuration chapters, youââ¬â¢ll find many Packet Tracer Activities that work with the Cisco Packet Tracer tool.Packet Tracer allows you to create networks, visualize how packets flow in the network, and use basic testing tools to determine whether the network would work. When you see this icon, you can use Packet Tracer with the listed file to perform a task suggested in this book. The a ctivity files are available in this bookââ¬â¢s CD-ROM; Packet Tracer software, however, is available through the Academy Connection website. Ask your instructor for access to Packet Tracer. The Labs and Activities portion of each chapter includes a Command Reference table, all the online Curriculum Labs, and a Packet Tracer Skills Integration Challenge Activity.The Curriculum Labs are divided into three categories: à ¦ Basic: The Basic Labs are procedural in nature and assume you have no experience configuring the technologies that are the topic of the lab. à ¦ Challenge: The Challenge Labs are implementation in nature and assume you have a firm enough grasp on the technologies to ââ¬Å"go it alone. â⬠These labs often only give you a general requirement that you must implement fully without the details of each small step. In other words, you must use the knowledge and skills you gained in the chapter text, activities, and Basic Lab to successfully complete the Challenge Labs.Avoid the temptation to work through 00_2028_fm. qxp 4/3/08 5:08 PM Page xix xix the Challenge Lab by flipping back through the Basic Lab when you are not sure of a command. Do not try to short-circuit your CCNA training. You need a deep understanding CCNA knowledge and skills to ultimately be successful on the CCNA exam. à ¦ Troubleshooting: The Troubleshooting Labs will ask you to fix a broken network. These labs include corrupted scripts you purposefully load onto the routers. Then you use troubleshooting techniques to isolate problems and implement a solution.By the end of the lab, you should have a functional network with full end-to-end connectivity. Packet Tracer Companion Most of the hands-on labs include Packet Tracer Companion Activities where you can use Packet Tracer to complete a simulation of the lab. Packet Tracer Challenge Each chapter also includes a culminating activity called the Packet Tracer Skills Integration Challenge. These activities require you to pul l together several skills learned from the chapterââ¬â and from previous chapters and coursesââ¬âto successfully complete one comprehensive exercise. A Word About Packet TracerPacket Tracer is a self-paced, visual, interactive teaching and learning tool developed by Cisco. Lab activities are an important part of networking education. However, lab equipment can be a scarce resource. Packet Tracer provides a visual simulation of equipment and network processes to offset the challenge of limited equipment. Students can spend as much time as they like completing standard lab exercises through Packet Tracer, and have the option to work from home. Although Packet Tracer is not a substitute for real equipment, it allows students to practice using a command-line interface.This ââ¬Å"e-doingâ⬠capability is a fundamental component of learning how to configure routers and switches from the command line. Packet Tracer v4. x is available only to Cisco Networking Academies through the Academy Connection website. How This Book Is Organized Because the content of LAN Switching and Wireless, CCNA Exploration Companion Guide and the online curriculum is sequential, you should work through this Labs and Study Guide in order beginning with Chapter 1. The book covers the major topic headings in the same sequence as the online curriculum for the CCNA Exploration LAN Switching and Wireless course.This book has seven chapters, with the same numbers and names as the online course chapters. If necessary, a chapter uses a single topology for the exercises in the Study Guide portion. The single topology per chapter allows for better continuity and easier understanding of switching commands, operations, and outputs. However, the topology is different from the one used in the online curriculum and the Companion Guide. A different topology affords you the opportunity to practice your knowledge and skills without just simply recording the information you find in the text. à ¦ Chapter 1, ââ¬Å"LAN Designâ⬠: The exercises in the Study Guide portion focus on LAN design concepts, including vocabulary and the three-layer hierarchical model.

Cable a network that is similar to the one shown in Figure 6-4. You can use any current switch in your lab as long as it has the required interfaces shown in Figure 6-4 and supports 802. 1Q encapsulation. The router you choose must support inter-VLAN routing. The output shown in this lab is based on Cisco 2960 switches and an 1841 router.Other switch or router models may produce different output. Set up console connections to all three switches. Step 2. Clear any existing configurations on the switches. Clear NVRAM, delete the vlan. dat file, and reload the switches. Refer to ââ¬Å"Lab 2-1: Basic Switch Configuration (2. 5. 1)â⬠if necessary for the procedure. After the reload is complete, use the show vlan command to confirm that only default VLANs exist and that all ports are assigned to VLAN 1.

Airline Pricing Strategies Research Paper Example | Topics and Well Written Essays - 4000 words
Airline Pricing Strategies - Research Paper Example The airline industry faces an unpredictable and often uncertain environment that is driven by trends in consumer behavior, internal demands placed on specific organizations, and a competitive environment that often dictates forward momentum. Revenue management systems, on average, function as a tool with which to remove certain business activities that are calculated to be inefficient or budget-restrictive. In this system, ââ¬Å"comparative trials of complex pricing policies are employed according to an application schedule that has a periodic character with respect to the arrival date of quoting circumstancesâ⬠(patents.com, 2008, p.1). In many businesses, these systems become automated in order to link inventory with actual usage time that can be calculated on a variety of electronic systems. Marriott Hotels took advantage of combining two different revenue management systems to link customer needs with internal operational components to ensure that productivity measured with demand (Thibodeau, 2005). Airline companies must develop methods to measure productivity with inventory strategy, labor, and other industry-specific activities. All of these are related to the financial goals or current economic position of the specific airway carrier. Whilst being driven to satisfy customers with different demands placed on marketing efforts, airline companies also manage expenditures balanced with the organization considered much like a system. The research identifies information associated with revenue production, advertising as part of marketing, internal functions and organizational constraints with the design of the airline carrier, and general business activities in the airline industry.Ã

Cause effect essay Example | Topics and Well Written Essays - 250 words
Cause effect - Essay Example in Effects of Poverty 1). To join a school like fellow children may just remain as a dream for many children as their families do not have favorable financial positions. Struggling becomes common to those families in every corner of life. This can make their children grow up under continuous mental stress and inferiority complex as comparisons are inevitable while competing with others who are better privileged. Also, inability to afford nutritious food coupled with poor living standards creates a dampening effect on childrenââ¬â¢s physical well-being. They become prone to various infections and growth problems. Apart from these, poverty can make a person develop hatred towards society which may influence his/her attitudes towards others. Unfortunately, innocent people are often affected as a consequence of such attitudes. Various observations also suggest a strong correlation between increase in poverty and crime rates (Effects of Poverty 1). To conclude, poverty can severely impact the well-being of individuals. Lack of adequate financial resources make those people suffer from poor living standards, diseases, and distress which may collectively influence their behavior towards society in a dangerous

Social media organizations PowerPoint Presentation
Social media organizations - PowerPoint Presentation Example It is my belief that because of this approach, Anne Rice has in fact made steps to become closer to her fans, and people on her page started realizing that there is more to her than a writer. Ms. Rice uses social media daily. If she is unable to post information about her latest media appearance, she posts her own opinion about issues that interest her. She also asks her fans questions about the characters in her books, hence increasing awareness about work. By interacting daily with her fans, she has gained new supporters. In Facebook alone, there are almost 1 million members of her page. Meanwhile, she has more than 70,000 followers in Twitter. Who knows how many more are part of her mailing list. We do know, however, that Ms. Rice receives numerous invitations for interview as she posts her interview schedules in her Facebook Page and Twitter account. This is because Ms. Rice also enabled visitors to her website to have immediate access to her secretary who sets up appointments for her. Based on these observations, I can say that Anne Rice can sustain her position as one of the most awarded writers today, thanks to her use of social media. She was already a household name in the past, but because of her active involvement in social media, more teenagers are becoming aware of her work and she is receiving support from almost all age

Self Defense And International Law Case Study Example | Topics and Well Written Essays - 1500 words
Self Defense And International Law - Case Study Example However the action initiated by the Republic of Bona by invading Malox can be termed as legitimate on the grounds of self defense as stated by the Republic of Bona. According to the Article 51 of UN Charter, the guidelines laid down by the United Nations Security Council will not weaken the rights of self defense of the member state of United Nations against armed attack carred out on them, until the Security Council has taken measures necessary to maintain international peace and security. Measures taken by Members in the exercise of this right of self-defence shall be immediately reported to the Security Council and shall not in any way affect the authority and responsibility of the Security Council under the present Charter to take at any time such action as it deems necessary in order to maintain or restore international peace and security. The invasion is legitimate on the grounds of self defense, until the Security Council takes stringent measures against the Malox Government. But instead, the Republic of Bona could have brought to the notice of Security Council, that it has evidence to show that the Alliance is responsible for the massacre that has taken place. Even though, one of the UN Security Council member, Kumara is an ally of the Alliance, he cannot on his own dismantle the efforts of the Bona Republic to counter terrorism. Then the Security Council may decide what measures, not involving the use of armed force, are to be employed to give effect to its decisions, and it may call upon the Members of the United Nations to apply such measures. These may include complete or partial interruption of economic relations and of rail, sea, air, postal, telegraphic, radio, and other means of communication, and the severance of diplomatic relations as laid down in the Article 41 of United Nations Charter of International Laws. In this process, the Bona Republican has used cluster bombs, white phosphorus and depleted uranium to locate and destroy the Alliance terrorist camp before further more attacks on themselves. The arms that have been used by the Bona Republican are Weapons of Mass Destruction (WMD) which not only kills persons but will degrade the environment. The degraded environment will make the life on the particular place not only difficult but the persons living there will be effected in the sense, they may get physically or mentally handicapped. The next generation childs may be born physically or mentally handicapped as wel. Such mass destruction will also lead to failure in plantation and degradation of other human necessities. On the grounds of humanitarian, use of such WMD's shall be avoided, just to destroy the Allaince Terrorist Group. However, United Nations has condemned the use of WMD's that has severe and drastic effect on the life of human beings and the next generation. Massive amo unts of circumstantial evidence strongly suggests that the use of DU ammunition has known to cause dramatic side effects, such as health problems, stillborn babies, toxic and poisonous land, water supplies, and residential territories. Such ammunitions is unethical for we will demean ourselves as a civilized

Researched Drama Paper (Hamlet) Research Proposal
Researched Drama Paper (Hamlet) - Research Proposal Example The Shakespeares were a prosperous and locally prominent family. His father, John Shakespeare, was a successful businessman. A great deal is known of Stratford which enables us to understand something of Shakespeareââ¬â¢s boyhood there. The town supported a grammar school which was free to the sons of Burgesses of whom Shakespeare was one. He also went to Grammar school. It is not known what Shakespeare did between the time he left school and his departure for London. Some stories about him that he got into trouble for poaching deer ââ¬â are possible, but unproved. He married Ann Hathaway, daughter of a yeoman farmer. Their first child was Susan and later, twins, Hamnet and Judith. Very soon after the latterââ¬â¢s birth, Shakespeare departed for London without his family. Shakespeare entered the theater as an actor and was to be an actor-manager for the rest of his life. He made money also as a playwright. Shakespeare died in Stratford in 1616 at the unbelievably early age of 52. Shakespeare wrote the following plays in a period of eight and nine years. Julius Ceasar; Hamelt; Allââ¬â¢s Well that Ends Well; Troilus and Cressida; Measure for Measure; Othello; King Lear; Macbeth; Antony and Cleopatra; Timon of Athens; Corionalus. Hamlet has been adjudged the best of men and the worst of men. Mark van Doren in his introduction to the play states that something in his personality renders him superior to decision and incapable of acting. His antic disposition has been analyzed as both a sign of abnormality as well as a device for seeming to be mad. One judgment is as good as another. Very little can be said that will be untrue of this brilliant and abounding young man. Opinions have differed as to which other character can best bring out Hamletââ¬â¢s character to the fore. Many writers would probably choose Horatio, his close friend and ally who supports Hamlet throughout the story, who echoes his way of thinking and is all praises for him. For
