10. • The CCENT certification requires a single step: pass the ICND1 exam. Simple enough.
• The CCNA Routing and Switching certification gives you two options, as show in Figure I-1: Pass
both the ICND1 and ICND2
• exams, or just pass the CCNA exam. (Note that there is no separate certification for passing the
ICND2 exam.)

12. Types of Questions on the Exams :(EXAM PATTERN)
The ICND1, ICND2, and CCNA exams all follow the same general format. At the testing center, you will sit
in a quiet room with
a PC. Before the exam timer begins, you will have a chance to do a few other tasks on the PC—for
example, you can take a
sample quiz just to get accustomed to the PC and the testing engine. Anyone who has user-level skills in
getting around a PC
should have no problems with the testing environment.
After the exam starts, the screen shows you question after question. The questions typically fall into one of
the following
categories:
• Multiple-choice (MC) single answer
• Multiple-choice (MC) multiple answer
• Testlet
• Drag-and-drop (DND)
• Simulated lab (Sim)
• Simlet
The first three items in the list are all actually multiple-choice questions.

13. Jobs That Require CCNA
 Jobs That Require CCNA
 Computer Systems Analyst.
 Database Administrator.
 Health Information Technician.
 Help Desk Technician.
 Database Administration.
 Computer Systems Analyst.
 Database Administrator.
 Network Administrator.

14. why should join CCNA?
 You can expect a hike in your
designation and salary in your
current company.
 You can easily switch a job
demanding a hike in the salary.
 CCNA is recognized all over the world,
thus you can easily get a job abroad.
 Feeling of Self-recognition as CCIE is
the toughest IT examination

46. TCP/IP Model

47. IP defines datagram structures that encapsulate the data to be delivered. It
also defines addressing methods that are used to label the datagram
source and destination.
Internet Protocol

48. IP Addressing

49. Routing is the process of selecting paths in a network along which to send
network traffic. Routing is performed for many kinds of networks, including
the telephone network (circuit switching), electronic data networks (such as
the Internet), and transportation networks
