ccna 640-802 in 3 weeks?

can i pass CCNA exam by doing dummies. Will that be enough.

i want to give the exam asap, but since the exam fee is high, i am afraid i may fail.

plz guide me.

im a telecom engineer, and persuing PDGM in Telecom Management. Shuld i do CCNA cirtification. Most of the salyabus is covered in our course.

Iam confused about the course as it is divided in two parts.. Help me in this regards.. and from where can i  do the course self study or program as i m doing full time PGDM. 

Received my CCNA certificate from CISCO this morning. They sent a Certificate, Congratulation letter, and a Card. wonder what that card is for .. looks like a discount  card.

hmm if u reaaly wana learn CCNA then i think u should practice with real routers

that takes abt 45-60 days to learn CCNA thats ideal preparation for any one to grasp mthe knowledge :)

well you could do that,especially with a lot of help today you get with dumps and other question ares. but thats not the true way of studying .. am not preparing for this exam as i would for a collage exam.. tell me one thing "how do you count experience in terms of years or knowledge". i have never ever worked on a real router or for that matter have seen it physically but you put me "on the line" today am not scared to do it. this is the what i have learnt in this journey of my preparation "raise your -chin up and get ready to face the situation". so its not about passing exam with one week preparation or one month. its what you learn in that period.   boy! am getting so philosophical...... whooo hoooo!  

niranjan thats it ( ibelieve this comment is from an andharite)

 Nothing there to study in CCNA... We can read it in a week and pass the exam.. But we should have Real time experience in that subject to had grip in that...

Anup, very few companies see experience today that too for a very high position. If you know the work properly, no company will reject you. Not even Microsoft !!! I personally have seen many freshers directly getting into good companies in off campus just on the basis on their strong knowledge.

Secondly, You think a lot !!! :) Don't worry so much man, right at this moment, don't think what will happen after the exam. Right now just concentrate on ur exam. Be bindaas and face it. After the exam is over, then start planning for the placements. Remember, when your marks are good in CCNA, no company can neglect you....

i heard people say that for ccna exam you need to know answer to a question from topic#2 inorder to answer question from topic#1... hey can you help me with this "how exactly are loopback interfaces different from sub-interfaces"

for ex- we use sub-interfaces for point to point frame relay,  can we use loop back interfaces as well. if no why.

     and somebody please explain the fields that show up in "show processes" on a router. how different is connecting a modem to aux port and connecting a modem to console port. if we connect modem to aux port what cable should be used and what cable for connection modem to console port. thanks....
