Fully understanding the Project Management Institute’s (PMI ) approach to project management can be diffi-
cult. This is not because of the complexity of the material. The difficulty arises from having a body of knowl-
edge that is structured for referencing, not learning.
PMI divides the tasks associated with project management into 44 processes. There are also 44 different man-
agement activities that must be completed, in a specific order .
Network management is the poor cousin of network design and implementation.
All too often it is treated as an inconvenience by equipment manufacturers, or
forgotten entirely. But the ability to manage network devices is fundamental to
their utility, and a successful and functional network can only be built from equipment
that can be easily managed and operated.
Management refers to the ability to confi gure, control, operate, and diagnose
equipment. Of course, no vendor ships devices that cannot be managed, but
typically each is operated and controlled in a different way.
• Validate user experience
connectivity, response times
• Anticipate network change
failures, growth, user mobility, new apps online
• Enforce conformance with corporate policies
user auditing/control, user/application differentiation
• Report findings to management
who’s not happy, what’s my ROI
• Identify how to leverage network as an asset
Implementing and Managing Networks
Describe the elements and benefits of project management
Manage a network implementation project
Understand network management and the importance of baselining to assess a network’s health
Plan and follow regular hardware and software maintenance routines
Describe the steps involved in upgrading network hardware and software
Optical Switching Networks describes all the major switching paradigms developed for
modern optical networks, discussing their operation, advantages, disadvantages, and
implementation. Following a review of the evolution of optical wavelength division
multiplexing (WDM) networks, an overview of the future of optical networks is set out.
Welcome to the exciting world of Cisco certification! You have picked up this book because
you want something better; namely, a better job with more satisfaction. Rest assured that you
have made a good decision. Cisco certification can help you get your first networking job, or
more money and a promotion if you are already in the field.
Cisco certification can also improve your understanding of the internetworking of more
than just Cisco products: You will develop a complete understanding of networking and how
different network topologies work together to form a network.
Internetworking---the communication between two or more networks---encompasses every aspect of
connecting computers together. Internetworks have grown to support vastly disparate end-system
communication requirements. An internetwork requires many protocols and features to permit scalability
and manageability without constant manual intervention. Large internetworks can consist of the
following three distinct components:
The Cisco® Networking Academy® course on CCNA® Security provides a next step for students who
want to expand their CCNA-level skill set to prepare for a career in network security. The CCNA
Security course also prepares students for the Implementing Cisco IOS® Network Security (IINS)
certification exam (640-553), which leads to the CCNA Security certification.
The CCNA Security Lab Manual provides you with all 11 labs from the course designed as hands-on
practice to master the knowledge and skills needed to prepare for entry-level security specialist careers....
In addition to an explosion of touch points, we are faced with an infinitively
complex and rapidly changing web of networks, applications, systems, client software,
and service providers. Under these circumstances, absolute security cannot be guaranteed
since it’s impossible to test the security implications of every configuration combination
of hardware and software under every set of conditions.
More complex networking services in Red Hat Linux require more advanced
administration methods. While graphical tools such as Network Configuration
(via the redhat-config-network command) are available to assist in configuring
all aspects of Linux networking, the best way to learn networking is by practicing with the key
command line utilities and associated configuration files.
Over the last ten years, the impact of wireless communications on
the way we live and do business has been surpassed only by the impact
of the Internet. Cell phones, pagers, and wireless Personal Digital
Assistants (PDAs) have become so commonplace in our lives that it is
easy to forget that ten years ago, they were a rarity.
One of the keys to understanding Cisco is the OSI model. The OSI model permits
people to understand how internetwork works and it serves as a guideline or framework
for creating and implementing network standards, devices, and internetworking schemes.
Some of the advantages of the OSI model include:
• It allows for the breaking down of complex operation into simple elements;
• Enables engineers to specialize the design and development of modular elements;
• It provides standards for plug and play and multivendor integration....
Our goal in writing Network Intrusion Detection, Third Edition has been to
empower you as an analyst. We believe that if you read this book cover to
cover, and put the material into practice as you go, you will be ready to
enter the world of intrusion analysis. Many people have read our books, or
attended our live class offered by SANS, and the lights have gone on;
then, they are off to the races. We will cover the technical material, the
workings of TCP/IP, and also make every effort to help you understand
how an analyst thinks through dozens of examples....

The following 3 questions all refer to the scenario below: The company Certkiller
manufactures and imports fasteners like bolts and nuts. The company's network consists of a main campus
composed of three separate building that are less than 150 meters apart, connected with Category 5e copper
wiring. Network access as well as distribution takes place by means of 100 Mbps hubs, and the core is a 100
Mbps Layer-2 switch. The company has been in existence for 8 years and thus development in the network
resulted in a series of steps that involved minimal planning.
This chapter presents a high-level overview of several basic models that you can
use in designing your IP telephony network. This overview provides some
guidance with respect to when and why a particular design should be selected.
Subsequent chapters delve into each network model in greater detail, beginning
with the simplest model and building to increasingly complexity models.
