Cisco’s CCNA certiﬁcation proves that you have a ﬁrm foundation in the most important
components of the Cisco product line—namely, routers and switches. It also proves that you
have a broad knowledge of protocols and networking technologies. CCNA is not an easy
certiﬁcation to get, but it is well worth the effort. In a booming economy, CCNA is the ﬁrst
step toward getting a higher salary than your noncertiﬁed peers. In a difﬁcult economy, it
could be the difference between whether a prospective employer even looks at your résumé.
According to Eric Vanderburg of certmag.com, the CCNA is “Cisco's introductory certification and the one in greatest demand. Cisco products
often are the first thought when choosing network infrastructure equipment, and they are immensely prevalent, creating a vast need for
professionals who are capable of managing them.”
On June 25, 2007, Cisco announced major updates to their CCNA curricula, including the new version of the CCNA Composite Exam (640-
The Cisco CCNA Security curriculum provides foundational network security knowledge, practical experience, opportunities for career exploration, and soft-skills development to help students prepare for careers with network security responsibilities. CCNA Security includes a comprehensive set of hands-on, online laboratories.

Cisco certification can also improve your understanding of the internet-
working 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. This is beneficial to every networking job and is
the reason Cisco certification is in such high demand, even at companies with
few Cisco devices.
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.

The Cisco Certiﬁed Internetwork Expert (CCIE) certiﬁcation program has been available since
the early ’90s. This long-standing certiﬁcation has maintained a high degree of credibility and
is recognized as a certiﬁcation that lives up to the name “expert.” The CCIE certiﬁcation process
requires passing a computer based test and then a two-day hands-on lab. Recertiﬁcation is
required every two years to ensure that the individual has kept skills up-to-date.
At Cisco Press, our goal is to create in-depth technical books of the highest quality and value. Each book is
crafted with care and precision, undergoing rigorous development that involves the unique expertise of
members from the professional technical community.
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....
Cisco’s Cisco Certified Network Administrator (CCNA) certification provides a way to distin-
guish those brilliant and talented enough to become Cisco administrators from those who just
might be, umm—well, better suited to another occupation. It’s basically Cisco’s version of sep-
arating the wheat from the chaff. The main reason that it’s a really good thing to be the proud
possessor of Cisco’s certifications is that they give you a serious edge over the poor, wretched,
unfortunate, and noncertified masses.
Professional certifications have been an important part of the computing industry for many years and will
continue to become more important. Many reasons exist for these certifications, but the most popularly cited
reason is that of credibility. All other considerations held equal, the certified employee/consultant/job candidate
is considered more valuable than one who is not.
Objectives and Methods
The most important and somewhat obvious objective of this book is to help you pass the CCNA exam
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....
