Share your CCDA Experience

Hi AMIR,
What does “D&D have same description” mean? I plan to take ccda on Thursday, thanks.

Hi JP,
If I remmeber correctly the question was:
static –> single isp link
bgp –> multiple isp link
small mesh –> Rip
large homogeneous network –> OSPF
large homogeneous network –> EIGRP

If you read TI and dstut carefully you will pass it easyly. :)

passed today 974/1000 all from here with all D&Ds and the new one Amir mentiones tested with TI 5,71

@ Amir one was small homogeneous other large homogeneous network, I think i failed on that one a bit, hence the 974

@ Dstut well done again TuT as the voice one this one was cake after learning your site!
up to route for me do hope you will get Arch up soon ;-)

Scheduled to take the test on the 5th. Trying to get it before the change. Been studying like a mad man the past few days. I recently took the ccna voice and passed on the 25th.

hey, how many items this exam has??

@Mark
ops, why? I just read both, both was same for me.
Can you write down the question?

Hi,
How to calculate the number of calls for a certain amount of bandwidth ?
Thx

hey, am pretty sure the D&D for me said

single isp link – static
multiple isp link – BGP
small mesh – RIP
small homogeneous network – OSPF/EIGRP
large homogeneous network – EIGRP/OSPF

not sure which is correct think i used OSPF for small EIGRP for large
cheers

Hey gabe,

I am also going to take it on the 5th! Good luck to you and everyone else!

Neptune:

I too struggle to calculate the number of calls for a certain bandwidth. So I’m just going with a few memorizations which are:

G.711 82.4 Kbps (no CRTP) & 67.2 Kbps (w/CRTP)
G.728 34.4 Kbps (no CRTP) & 19.2 Kbps (w/CRTP)
G.729 26.4 Kbps (no CRTP) & 11.2 Kbps (w/CRTP)

This information comes from the Cisco Voice over IP Authorized Self-Study Guide (page 89).

If you go to this web site on the Voice Design option, there are two questions asking for bandwidth calculations. Use the above information, retake the questions and you’ll see the desired correct answers. Make sure to note that one questions asks for CRTP and one does not. I know it would be better to know the actual way to perform the calculation but I can’t seem to figure it out. So I’ll memorize a few numbers and more onto whatever comes next. I’m taking the CCDA exam on Nov. 4th. Good luck with your test.

I took the exam last thursday, got 1000, the correct D&D is:

single isp link – static
multiple isp link – BGP
small mesh – RIP
homogeneous network – OSPF
heterogeneous network – EIGRP

Go for the exam before nov 8, with the information provided you will pass it, only found 3 new questions; good luck

Neptune:

Voice Packet size = ( packet_header + CRTP + payload) x 8 = ____ bits

Voice Packets per sec = bit_rate / (payload x 8) = ____ pps

BW = Voice_packet_size x voice_packets_persec = ____ bps

#calls = WAN_BW / BW

*** If CRTP = yes, then its value is 4
= no, then it is 2

The bit_rate depends on the Codec

Good Luck

Hey Mil,

The normal IP/UDP/RTP packet header is 40 bytes and if cRTP is being used, it’s only 2 bytes.

fcisco:
Thanks, you are wright, I got it backwards, it is smaller if CRTP is being used because it is compressed :S, with CRTP is 2.

Hey Mil,

I was looking over your proposed solution to the D&D that is not covered in the dstut D&D section; referring to matching the link type with the appropriate routing protocol selection.

single isp link – static
multiple isp link – BGP
small mesh – RIP
homogeneous network – OSPF
heterogeneous network – EIGRP

I agree with the first three selections but feel like the last two should be swapped around. If you think about, how could EIGRP be used in a heterogeneous networked environment? I’m interpreting heterogeneous here as “mixed” aka “non-cisco devices”. When using EIGRP you MUST use all Cisco equipment since the protocol is proprietary. OSPF, on the other hand IS able to use “mixed-network” devices. To me this answer would make more sense:

single isp link – static
multiple isp link – BGP
small mesh – RIP
homogeneous network – EIGRP
heterogeneous network – OSPF

thoughts?

Mil, Mark

What is the correct answer for a question:
Which three types of WAN topologies can be deployed in the Cisco Enterprise Architecture Enterprise Edge WAN module? (Choose three.)
A. ring
B. full mesh
C. partial mesh
D. collapsed core
E. star
F. core
G. edge

Answer: B, D, E

What did you choose?… partial mesh or collapsed core?
Thanks

Hi,

cbe:
I think you are wright, your arguments are correct. Maybe this is one of the demo questions of the exam (according to the terms of the exam, there are up to 3 demo questions whose answer doesn´t affect your total grade) and that is why I got a perfect score.

strr:
The correct answers are: full mesh, partial mesh and star.

i got a new D&D not covered on this site. I don’t remember the exact answers. What I remember is the following:

Match the following devices with elements of the Cisco Unified Wireless Network:

There’s a bunch of devices listed and five elements of the Cisco UWN on the right side. The following is the mapping I attempted. I don’t know if I got it right or not:

CCx3 notebook –> Wireless endpoint
WLC2006 –> Unified Management
WCS –> Mobility Control
1242AG –> Access point

Good luck everyone!

Ok I take for example Q6 in Voice questions:

Codec: G.728
Bit rate: 16 Kbps
WAN Bandwidth: 256 Kbps
Packet Header: 6 bytes
Payload: 40 bytes
CRTP: Yes

Voice Packet size = (6 + 4 + 40) x 8 = 400 bits
Voice Packets per sec = 16 / (40 x 8) = 0.05 pps
BW = 400 x 0.05 = 20 bps
# calls = 256 / 20 = 12.8 (~13 calls)

It seems match the result! Thank you!

Just passed a few hours ago 1000/1000. 3 new dnd…. like that posted ahead.

Tks Dstut and MMFSH!!

What were the new dnd? Are they the ones posted above from the other posters?

Just passed a few hours ago 1000/1000
1 new d&d – something with wan technology description (i used isdn, sonet, frame relay, tdm), the rest of the questions are on this page – big thanks for it!

Just passed, 974/1000. Got two or three new questions. Two which I vaguely remember were both D&D. Both questions were matching the appropriate technology with the correct description. I don’t remember the descriptions of the technologies involved but tried to quickly jot down the technologies at least. So if you were to look these up and really know what they are/used for, you should have no problems.

D&D Question 1 had these terms: Frame Relay, Circuit Switched, and Packet Switched.

D&D Question 2 had these terms: DWDM, TDM, SONET, ISDN, Analog Modem. I think there were a couple more on this question but don’t recall exactly what the terms used were.

Good Luck!!

DOES ANYONE ,BY CHANCE , HAVE ANY MATERIAL ON :IMPLEMENTING CISCO STORAGE NETWORKING SOLUTIONS(ICSNS)?VIDEOS OR BOOKS?

Passed the test with a 989. Had the same dnd as mysiak. Since mysiak got the perfect score I recommend answering them in the order he/she did.

@Jdsan
CCx3 notebook –> Wireless endpoint
WLC2006 –> Unified Management
WCS –> Mobility Control
1242AG –> Access point

You almost had it correct, WLC2006 is the Wireless LAN Controller which would be the Mobility Control and WCS is the Wireless Control System which would be the Unified Management in this case. I am writing the exam tomorrow and will probably be the last one writing it in this old version, will let you all know how it goes :)

@CCVP

What I posted was vaguely what I remember from the exam. I probably did answer it the way you said but I can’t even remember that!

But I’ve given you the options available on both sides of the D&D and if it helps you even a little in answering the question, all the better!

Cheers.

la version de CCDA fue cambiada, yo lo iba a dar el exam el viernes pero el centro donde lo iba a dar lo desactivaron y me cambiaron la fecha, alguien tiene el nuevo material.

CCDA version was changed, I was going to take the exam on Friday but the center where it was going to give it turned off and I changed the date, someone has the new material.

Please someone has the new material CCDA. >:(

It may take a while for the new material to come out. In the meantime I recommend getting your hands on some material to study to really understand the concepts.

Passed the exam with a perfect score thanks to this site and digitut.

@JRS
Like Gabe suggested start with study material from Cisco and you will have to wait while till the new versions come out…Good luck !!

passed today 974 /1000 ;

Thanx everyone and good luck

Hello Everyone,

Does anyone know about similar site for CCDP ARCH.

Thanks,

Please, if someone plans to take the exam this week to share his experience.

@STR b,c,e

I passed it too the 5th November, all questions as expected! Thx everybody

i passed ccda exam on 24 oct 2010. 95% of questions was same. one new drag and drop question about wan technologies

Dear Sirs, greetings. I need student guides for CCDA preparation. But I could not find them.
Cold you help me to point to link where I can to donwload them. Thank you in advance.

info!! new exam CCDA. someone will give the exam this week.

I passed 640-863 with 1000/1000 on Nov 5th using this stuff http://www.careercert.info/2009/08/ccda-study-material.html
Special thanks to TestInside v5.71 (128 Q’s) and DSTUT for this excellent site!
Greetings from Costa Rica!

Has anyone taken the exam on or after November 8th? Are these questions still accurate?

I would imagine the questions are still valid. If anything Cisco might of added a few new ones for the new topics in v2.1 but I would imagine the bulk of these questions will still remain valid.

NOTF : I would be great if what you saying is true. I will continue reading ccda cisco press for ver 2.0, but If anyone has passed(or failed ;P) new version of exam please post your feelings about the exam.
Regards.

what is the prerequisite for the CCDA exam.

I have just completed ICND Part -1 in this month.

Good passed!!! tks :)

JRS: When did you pass? Are you in a position to confirm my previous post.

thanks for your beautiful website,

I am prepareing myself to get My CCDA, Unfortunately there is not enogh sources on the internet.
Pass4sure with 222 question is really needed??if anyone has sitten for the exam after 8.Nov.2010 please share information.

thanks a lot,

Folks they have extended the current exam till April 2011 so everything here is good and the CCDPs 642-873 exam extended till May 2011. Check Cisco’s website out!!!

DOES this exam still available??????????

@ANON can you give us a link or something.
