Share your CCNA Wireless Experience

Why WCS?? It’s an old subject, non covered in the officiali cert guide.

@Kriz the answer is C. OPEN

Hi guys How are you

Hi Guys, passed today 985, there are 3 new question and multiple choice changed to single choice.
good luck..

Hi @Kriz

can you share VCE file Dump Pls.
abstractz@h o t m a i l . c o m

Hi everybody, I passed yesterday 977. I had 65 questions, 103q is 100% valid.
NO WCS AT ALL
Regards

Now next challenge: what do you think about preparation for CCNP, no OCG at the moment…

@mateo next CUWSS or IAUWS

@kriz those are ‘old’ exams and material, last dates for those is 21 september..

Does anyone know where I can get a copy of the VCE file for the 103q dump?

Q32:A customer wants to deploy Cisco Cloud Wireless architecture with 802.11ac capabilities. Which two access
points would meet the customer’s requirements? (Choose two.)
A. Cisco 3700 Access Points
B. Cisco MR34 Access Points
C. Cisco MR18 Access Points
D. Cisco 3600 Access Points
E. Cisco MR72 Access Points
F. Cisco 1570 Access Points
G. Cisco MR26 Access Points
Correct Answer: AE

Guys dont you think answer should be BE? because question is about cloud wireless and 3700 is a lwap. Please update me if I get it wrong.

Passed 200-355 exam yesterday, 962/1000 marks, 65 questions in total.

Learned all questions from PassLeader 200-355 dumps: http://www.passleader.com/200-355.html

Some new 200-355 dumps collection: https://drive.google.com/open?id=0B-ob6L_QjGLpcXZkRGszbGJmUkE

Hi Gary,
Yes , the answer is BE. Cisco 3700 is not cloud based. If you are not sure, you can just search it online ;)

Hello 200-355 dump 103q is still valid?

Hi all,

Can someone confirm the 103q is still valid ?

@Toeao, it’s 1000% valid go take the exam sir, please go through if you’re having any questions on the 103Q

@Toeao, I mean go through the comments lol

togo_13@yah o o . c o m

@Simon, @kriz, @Abstractz can share VCE file of 103q? appreciate your kind response.

I have a question. It is about calculating approximate EIRP for link budget for a wireless point-to-point bridge. Specifically questions 73 from the 103q. I am having difficulty with dealing with mW dBm dBd and dBi…

My notes are that you have to convert dBd to dBi and the formula is
dBi = dBd +2.15.

Is this right?

QUESTION 73
When calculating the link budget for a wireless point-to-point bridge, the engineer notices that one antenna has its gain marked as 2.85 dBd. With a 20-mW access point and 3-dBi loss for the cable, what is the approximate
EIRP?
A. 15 dBm
B. 18 dBm
C. 22 dBm
D. 25 dBm

Answer is A. 15 dBm

And from what I can see on question 73 on the 103q I need to convert mW to dBm.

Very confusing and what are the conversion table for this? Anyone have an easy way to remember this?

Seems like this is the only thing that is holding me up before I take the test.

Any help would be much appreciated.
Thanks.

I think I answered my questions on converting mW to dB.

So if I am going from mW to dBm I just remember 10mW = 10dBm. Then use 10s and 3s to get to my dBm. In questions #73 I need to get 20mW to dBm. So I know that 10mW =10dBm so I take 10dBm and multiply by 2 to get 20. So 10 plus 3 = 13dBm

In question 73 I need to get dBm to dBi. So I take 2.85 dBm and add 2.15 to get 5dBi. We have a -3dBi loss on the cable so just add them up.

13 dBm + 5dBi – 3dBi gives us 15 dBm.

Crazy. Did anyone see that? Happen fast didn’t it?

I saw some post on this earlier on page 19, but wanted to see if I could write it out and understand it. I think I got it…

@everyone hey if your looking for CCNP wireless training my mentor/boss is on the board wifitraining .com

@kriz I saw your question earlier this morning, first off congrats on passing…my boy @jdrane was correct the answer is C open. Lets dig a little deeper why this answer is C….This question dealing with the authentication part of connecting to a wireless network….remember the two A’s: authentication and association.

Back in the days of 802.11 prime and 802.11b the main two ways of authenticating were open and WEP. As we know WEP is unsecure and isn’t used anymore. WEP is still stated for legacy and backwards compatibility IF needed but shouldn’t be used.

Open like WEP is still around….with Open its the authentication part used on most all 802.11 networks. Its used for both the AP and the client to let each other know they are both 802.11 devices and able to communicate. Once that happens you move on to the association portion and thats where all the other magic happens.

On to the other answers and why incorrect:
A) WPA2(TKIP) This is not correct whenever you have WPA2 you will always use AES
B) WPA(AES). WPA in of itself did not support AES when created, it used TKIP which was fully replaced by WPA2 AES
C) Open Answer above
D) WEP Answer above

Hope this helps

@Garry good day and welcome to the forum….I saw your question about Meraki and cloud support and setup….This is one of the few questions that is actually wrong on the 103q….I believe there was some good information on this on pages 14-16. The answer is MR34 and MR72..

@Wireless Junkie hey welcome on to the forum…..I saw your post about the dBm dBi dBd and mW question and you are correct…I’ve done a couple of posts on that question in the past…the Cisco Press book didnt do the best job of covering this….CWNA covers a lot of these types of questions…if you really enjoy tackling those types of questions look at the CWNA…I learned a lot from studying for that certification

@jdrizzie hey thanks for the kind words….I’m here to help out however I can…I echo your comments about not just taking this test to get a certification….if you ever need some help understanding some concepts or anything reach out to me…

Manny,

How would you calculate the 4 mW in question #2 in the 103q? Or how do you get from 4 mW to dBm in this particular situation? I have no reference point to go by.

QUESTION 2
An  access  point  is  currently  transmitting  at  4  mW.  The  customer  needs  to  increase  its  signal  strength  by  6  dB to  create  a  larger  wireless  cell.  What  should  the  new  transmit  power  be?

A. 8 mW
B. 10  mW
C. 12  mW
D. 16  mW
E. 24  mW

Correct Answer: D

@Wireless Junkie…..ok lets tackle this bad boy…..key to remember is for every 3dB you add you double the power for every 10dB you ten times the power….3s and 10s…..

So we got 4mW thats our base and were gonna raise it 6dB…so that 3dB two times….
4mW +3dB = 8mW (remember its a double)

Now were at 8mW..
8mW + 3dB = 16mW (its a double again)

Key is to break down the dB to either multiples of 3 or 10…once you figure that out you can figure out how many times to double or 10x the mW

So thats how you get answer D….hope this helps….

Guys,

Just want to say thank you for posting and sharing your knowledge. It is very helpful and aids in clarification and understanding of the material. I’ve read the OCG, used the Prime config guide, WLC guide, various websites, and used the 103q as well as the passleader dumps to help me pass the exam this morning. I do feel that you must test yourself with these dumps to get a feel for the “Cisco” structure and presentation of the test questions. With out it, I think one would somewhat struggle even having read and studied the material. I know I would have.

Like Manny and some of the other contributors/posters have written, do take the time to understand the concepts and how to deduce the learned knowledge to solve problems rather that just memorizing dumps, it will help you in your career and keep the merit in the cert itself. Thanks guys!

Manny,

No that doesn’t make sense. You can’t add mW with dB. Don’t you first have to convert mW to db?

Manny,

Here is another one:

QUESTION 19

A  network  engineer  notices  that  two  mesh  APs  are  having  problems  communicating.  After  reviewing  the  current radio  configurations,  it  is  noted  that  one  AP  is  transmitting  at  3  mW  while  the  other  is  transmitting  at  60  mW. How many decibels  would  the  3-mW  AP  need  its  power  increased  to  match  the  60-mW  AP?

A. 8
B. 12
C. 13
D. 20
E. 57

Correct Answer: C

My question is how are you getting from mW to db? Can you show me the formula to remember or show me the math?

@Wireless Junkie…..so questions are great but I know a lot of us ask “When will I use this in real life?” I would like to give you a great example…..

Lets take the 3702 and the 1131 AP from Cisco….3702 is pretty new and a lot of older environments you will still see the 1131 (we still have them lol).

So when you are dealing with the raising/lowering power on those guys from the controller all you see is power level 1-6 or 1-8 dealing with the model and channel band.

Well they both go to a power level 1 on 5GHz UNII-3 but what does that really mean….and its pretty shocking!!!!

PL 1 on the 1131 is 17dBm and PL1 on the 3702 is 23dBm….the difference between that is 6dB…
From our scenario questions and formula 6dB is 2x power plus 2x power…..

In other words the 1131 is 50mW and the 3702 is 200mW…..THATS A HUGE DIFFERENCE!!! You would never want the 3702 running at Power Level 1 in an indoor environment……

OK. I understand question 19. How about question 2? Can you go through that question like you did with 19?

I don’t see how to use 3s and 10s on the question 2. How do I go from 4mW to 6 dB?

4 x 2 = 8. I went over 6. See my confusion?

Thanks Manny and Den. Going to take my exam in the morning. will share my experience. fingers crossed.

@Junkie
Here is the explanation of question 2

lets say the new transmit power is 16mW. How many dB changes from 4mW to 16mW
=10log16-10log4
=10log(16/4)= 10log4= 10log(2*2)=10log2+10log2=3+3=6dB

I hope it makes sense

How about this one?
QUESTION 88
After the initial deployment at a customer site, the master controller mode function was left enabled on the secondary controller after access points were primed and statically configured with primary, secondary, and tertiary controller failover. The guest anchor controller was also deployed in the architecture. The access points reboot after a power failure. Which controller will the access points associate to when the reboot process is completed?
A. primary controller
B. secondary controller
C. tertiary controller
D. guest anchor controller
Correct Answer: B

I think the answer should be A. Primary controller.
After reboot an ap always joins the primed controllers first.

@Garry hello and good morning….this is a great question we went over this one I believe on page 18….@Conrd and I had a long discussion….this is one of the few questions on 103Q that the answers are wrong….it is answer A Primary controller….The controller will always look at the primed controller configuration first…

@wireless Junkie….hey good morning…I think I see your confusion on question 2…..let me see if I can help….

So that 4mW needs to be raised by 6dB…..let me try to explain it using power levels on a controller/AP as just an example…..its like he’s asking to go from a power level 3 to a power level 1

For every power level you add +3dB….so to go from power level 3 to power level 2 you add 3dB(which doubles the mW power)…to go from power level 2 to power level 1 you add 3dB again(which doubles the mW power again)

In reality you added 6dB to power level 3 to move to power level 1

Same thing with this question take the 6dB you are going to add and break it down into two separate 3dB level….

If you were going to add 9dB you would add 3dB three times

For every 3dB you raise, you double the amount of mW
+3dB = 4mW x 2 = 8mW
+3dB = 8mW x 2 = 16mW
+3dB = 16mW x 2 = 32mW

@wireless Junkie…..in your previous comment you also say

” don’t see how to use 3s and 10s on the question 2. How do I go from 4mW to 6 dB?
4 x 2 = 8. I went over 6. See my confusion?”

I believe the confusion there is you don’t have your numbers labeled…..its not 6mW your adding your raising it 6dB….

4mW x 2(+3db) = 8mW

8mW does not equal 6dB

8mW x2(+3dB) = 16mW

Total: 4mW was raised by a gain of +6dB = 16mW

Hi guys, need help. How can I get the 103Q? Almost every comment is related to the 103Q but found no link, no clue on how/where to get it. Can you help? antoniosantos1618 @ g m a i l . com

Took the exam today morning. 977/1000.
103q is 100% valid.

@antonio sent you in the email. good luck

Whic quesitons 100% valid. please send me , pleaseee
( learning.networking.ever@g m a i l.com )

To those who are looking for the 103Q there are comments on page 18 regarding a link to the google drive…..

Please take the time to go through pages 14-20 there is a wealth of information from others regarding questions on the test and explanations on why they are answered like that

Finally to those looking for 103Q please take the time to study the material on the concepts of the certification exam….there is a lot of good knowledge in the books, here on this forum, and videos on the internet….getting a certification just to put on a resume will not help if you get put in the position of an interview with an employer who knows wireless

@Garry congrats on passing the exam….what will you move on to now?

@manny thanks. Going for ccnp. but not sure which one I should take first. Any suggestions? I know 742 series gonna end in sep. Should I go and take one before sep 21 or should I go for 300 series straight?

@Garry cool cool on the CCNPW track……I’m going CWSP as my next one…..I personally say you should move on to the 300….I actually got signed up for the 742 series from global knowledge…took the first 2 hours and I was like WTH….dude they were talking about pre ISE and pre Prime stuff I hadn’t seen in years….the instructor even said they have gone past EOL on these applications…

@Garry the only thing I can add to that is if you know the old school applications then maybe you can squeeze one test in before the date….I know they are allowing you to mix and match old to new…me I’ve only been a couple of years in a real WiFi role and my environment is surrounded by ISE, Prime, and 8.x controllers

@Manny I’m in the same boat. Just started wireless career couple of years ago and now i’m all in. Lets see how far it goes along.
Best of luck for your next exam.
I will decide in couple of days.
