What Skills Do You Need to Become a CCNA?

To meet the CCNA certification skill level, you must be able to understand or do the following:

·         Install, configure, and operate simple-routed LAN, routed WAN, and switched LAN and LANE networks.

·         Understand and be able to configure IP, IGRP, IPX, serial, AppleTalk, Frame Relay, IP RIP, VLANs, IPX RIP, Ethernet, and access lists.

·         Install and/or configure a network.

·         Optimize WAN through Internet-access solutions that reduce bandwidth and WAN costs, using features such as filtering with access lists, bandwidth on demand (BOD), and dial-on-demand routing (DDR).

·         Provide remote access by integrating dial-up connectivity with traditional, remote LAN-to-LAN access, as well as supporting the higher levels of performance required for new applications such as Internet commerce, multimedia, etc.

How Do YouBecome a CCNA?

            The first step to becoming a CCNA is to pass one little test and—poof!— you’re a CCNA It’s just one test but you still have to possess enough knowledge to understand and you must have some hands-on experience with Cisco routers. If you can get a hold of some 2500 routers, you’re set. what they need to know to pass the CCNA exam.

Cisco’s Network Support Certifications

CCNA (Cisco Certified Network Associate)

            Cisco First Network Certification is the CCNA (Cisco Certified Network Associate) certification and it is a first step to all current Cisco certifications. It is a stepping-stone approach to CCIE certification. The Next Step is the Cisco Certified Network Professional (CCNP). Someone with a CCNP has all the skills and knowledge he or she needs to attempt the CCIE lab.

Why Become a CCNA?

            Cisco, not unlike Microsoft or Novell, has created the certification process to give administrators a set of skills and to equip prospective employers with a way to measure skills or match certain criteria. Becoming a CCNA can be the initial step of a successful journey toward a new, highly rewarding, and sustainable career.

            The CCNA program was created to provide a solid introduction not only to the Cisco Internetwork Operating System (IOS) and Cisco hardware, but also to internetworking in general, making it helpful to you in areas that is not exclusively Cisco’s. At this point in the certification process, it’s not unrealistic to imagine that future network managers—even those without Cisco equipment—could easily require Cisco certifications for their job applicants. If you make it through the CCNA and are still interested in Cisco and internetworking, you’re headed down a path to certain success.

Cisco—A Brief History

In the early 1980’s Len & Sandy Bosack, a married couple used to work in different computer departments at Stanford University was having trouble to communicate with their individual systems so they created a gateway server in their living room that made them to communicate with two computers using the IP protocol. In 1984, they founded Cisco Systems with a small commercial gateway server product which changed the Networking forever. In 1992 the company name was changed to Cisco Systems, Inc.

The first product the company marketed was called the Advanced Gateway Server (AGS). Then they introduced Mid-Range Gateway Server (MGS), the Compact Gateway Server (CGS), the Integrated Gateway Server (IGS), and the AGS+. Cisco calls these “the old alphabet soup products.” In 1993, Cisco came out with the amazing 4000 router and then created the even more amazing 7000, 2000, and 3000 series routers. These are still around and evolving (almost daily, it seems).

Cisco has since become an unrivaled worldwide leader in networking for the Internet. Its networking solutions can easily connect users who work from diverse devices on disparate networks. Cisco products make it simple for people to access and transfer information without regard to differences in time, place, or platform.

Cisco provides end-to-end networking solutions that customers can use to build an efficient, unified information infrastructure of their own or to connect to someone else’s. This is an important piece in the networking–industry puzzle because a common architecture that delivers consistent network services to all users. Because Cisco Systems offers such a broad range of networking and Internet services and capabilities, users needing regular access to their local network or the Internet can do so unhindered, making Cisco’s wares indispensable.

            Cisco answers this need with a wide range of hardware products that form information networks using the Cisco Internetwork Operating System (IOS) software. This software provides network services, paving the way for networked technical support and professional services to maintain and optimize all network operations.

            Along with the Cisco IOS, one of the services Cisco created to help support the vast amount of hardware it has engineered is the Cisco Certified Internetwork Expert (CCIE) program, which was designed specifically to equip people to effectively manage the vast quantity of installed Cisco networks.

          However, having a fabulous product line isn’t all it takes to guarantee the huge success that Cisco enjoys—lots of companies with great products are now defunct. If you have complicated products designed to solve complicated problems, you need knowledgeable people who are fully capable of Systems but the paper got ripped on the way to the installing, managing, and troubleshooting them.

             That part isn’t easy, so Cisco began the CCIE program to equip people to support these complicated networks. This program, known colloquially as the Doctorate of Networking, has also been very successful, primarily due to its extreme difficulty. Cisco continuously monitors the program, changing it as it sees fit, to make sure that it remains pertinent and accurately reflects the demands of today’s internetworking business environments. Building upon the highly successful CCIE program, CiscoCareer Certifications permit you to become certified at various levels of technical proficiency, spanning the disciplines of network design and support.

ccna interview questions

IAM POSTING THE CCNA INTERVIEW QUESTIONS PDF DOC WITH ANSWERS OF CCNA AND THESE QUESTIONS WILL HELP YOU ALL, AND ALSO YOU CAN FIND MANY TUTORIALS IN THE BELOW 

Question 21

Which NetWare protocol provides link-state routing?

A. NLSP

B. RIP

C. SAP

D. NCP

Ans: A

NetWare Link Services Protocol (NLSP) provides link-state routing. SAP (Service Advertisement Protocol) advertises network services. NCP (NetWare Core Protocol) provides client-to-server connections and applications. RIP is a distance vector routing protocol.

Question 22

As a system administrator, you want to debug igrp but are worried that the “debug IP igrp transaction” command will flood the console. What is the command that you should use?

A. debug IP igrp event

B. debug IP igrp-events

C. debug IP igrp summary

D. debug IP igrp events

Ans D

The “debug IP igrp events” is used to only display a summary of IGRP routing information. You can append an IP address onto either command to see only the IGRP updates from a neighbor.

Question 23

What does the following series of commands accomplish? router igrp 71 network 10.0.0.0 router igrp 109 network 172.68.7.0

A. It isolates networks 10.0.0.0 and 172.68.7.0.

B. It loads igrp for networks 109 and 71.

C. It disables RIP.

D. It disables all routing protocols.

Ans A

It isolates network 10.0.0.0 and 172.68.7.0 and associates autonomous systems 109 and 71 with IGRP. IGRP does not disable RIP, both can be used at the same time.

Question 24

In the command “router igrp 109″ what does 109 signify?

A. an autonomous system

B. any network number which the router is attached to

C. the allowable length of the routing table

D. the network socket number

Ans A

The Cisco IOS global configuration command “router igrp xxx” is used to configure the Interior Gateway Routing Protocol. In this case, the 109 is called the process-id , which can also be used for an autonomous system number.

Question 25

IGRP supports a feature that allows traffic to be distributed among up to 6 (4

default) paths to provide greater overall throughput and reliability. What is this called?

A. unequal-cost load balancing

B. equal-cost load balancing

C. proportionate load balancing

D. low cost load balancing

Ans A

An unequal-cost load balancing is used to provide alternate paths for data distribution on an internetwork. Cisco developed this method to use unused or under utilized links to increase bandwidth and network availability.

Question 26

IGRP uses flash updates, poison reverse updates, holddown times, and split horizon. How often does it broadcast its routing table updates?

A. 90 seconds

B. 10 seconds

C. 30 seconds

D. 45 seconds

Ans A

Question 27

The command “show IP protocol” displays which information?

A. routing timers

B. network information

C. contents of the IP routing table

D. information about all known network and subnetworks

Ans A & B

“show IP protocol” displays routing timers and network information. “show IP route” displays the routing table with information about all known networks and subnetworks.

Question 28

When using RIP, routing updates are broadcast every ____ seconds.

A. 30

B. 10

C. 60

D. 90

Ans: A

Novell’s RIP updates routing tables every 60 seconds, Apple’s RTMP is every 10 seconds, routers ARP every 60 seconds, DECnet hosts and IGRP signal every 15 seconds, and Banyan VINES signals every 90 seconds.

Question 29

An autonomous system can only exist if all routers in that system meet which criteria?

A. interconnected

B. run the same routing protocol

C. assigned same autonomous system number

D. run IGRP only

E. run RIP only

Ans A,B &C

An autonomous system is a set of routers and networks under the same administration. Each router must be interconnected, run the same routing protocol, and assigned the same autonomous system number. The network Information Center (NIC) assigns a unique autonomous system number to enterprises.

Question 30

A default route is analogous to a _________.

A. default gateway

B. static route

C. dynamic route

D. one-way route

Ans: A

A default route is analogous to a default gateway. It is used to reduce the length of routing tables and to provide complete routing capabilities when a router might not know the routes to all other networks.
