Thanks Z3r0, work in Brazil! 899/1000

Can anyone confirm that the new actualtest dumps are valid?

Don’t bother with the dump, it’s not valid. Here are some questions I can remember. Please provide input on which are correct:

Located in London, what’s the highest band used in the 5GHz: UNII-1, UNII-2, UNII-2E

What’s the highest power used for the 5GHz in the US: UNII-1, UNII-2, UNII-2E, UNII-3

How do you measure the beam width for signal and power: 3db, 6db, 10db, ½, ¼, 1/6, 1/8, 1/10….cant remember the rest of the options.

Something about egress of connection of AP on switch port: don’t remember the choices.

What does the gain of antenna produce: Think it’s either – Increase cell size or increase directional gain

Most overhead/administrative work required for network infrastructure: cloud or converged (Think it’s converged)

1 Drag and Drop: Absorption, Reflection, Scattering, Diffraction, Free Space Path Loss and Multipath. (No Refraction option) Pt to Pt open field, Pt to Pt with obstacles, Pt to Pt over body of water, going through wall, metal cabinet and pass through rain.

Default tab of Cisco Prime Infrastructure for rogue APs: Security, General, CleanAir, can’t remember other choice.

Picture of CLI error and what it indicates: Can’t remember the choices.

Which controller provides excess of 20 GBps throughout: 8510, 5760, 5500, can’t remember the other choice.

Someone could confirm the questions about MAC OS?

A customer who recently implemented Mac OS X Yosemite finds that the laptops have benn autonegotiating the authentication protocols when performing RADIUS authentication to ISE. What must the administator do to statically set the correct setting for the Mac clients?
1) Select the SSID and change the setting to the desired configuration under Control Panel > Network > Wireless Network and export to the other machines.

Mac OS X machines ares having issues accessing the wireless network. While working with TAC, the administator is asked to find the mac laptop´s wireless adpater model and driver. Where should the administrator look to find this information?

1) About this Mac > System Report
2) Control > System
3) Control Panel > Networking > adapters > properties
4) System Preferences > network > Wifi Adpater > advanced

ilsatch – Again here are my thoughts. Just curious on what your thoughts are for the answers to all the questions that you posted…

– Set de authentication configuration to use the desired setting under the system preferences network > advanced menu

– About this Mac > System Report

Joe,
The only response that i disagree with you is the drag and drop.

Reflection = Metal Cabinets
Free Space Path Loss = Distant point to point line of sight
Diffraction= Distant point to point with obstacles
Absortion = Rain
Scattering = Wooden Wall
Multipath = Body of water

Regarding the MAC OS questions, I don´t have any experience at all with that OS. Based on internet, the first question could be also the answer #2. Regarding the second one, could be also the answer #4.

What about this question

In version 8.0 code for CUWN, what interface can be assigned an ipv6 address?
1) AP-Manager
2) service-port
3) virtual
4) management
5) dynamic

I think the question only asks for one choice. What answer do you think it is? Service-port or the Management interface?

If it is only one, i think it will be the MGMT Interface.

I was thinking the same thing. Any chance you know the answers to any of these:

Located in London, what’s the highest band used in the 5GHz: UNII-1, UNII-2, UNII-2E

What’s the highest power used for the 5GHz in the US: UNII-1, UNII-2, UNII-2E, UNII-3

How do you measure the beam width for signal and power: 3db, 6db, 10db, ½, ¼, 1/6, 1/8, 1/10

Most overhead/administrative work required for network infrastructure: cloud, converged (Can’t remember other choices)

Default tab of Cisco Prime Infrastructure for rogue APs: Security, General, CleanAir, (Can’t remember other choice)

Which controller provides excess of 20 GBps throughout: 8510, 5760, 5500, (can’t remember the other choice)

Located in London, what’s the highest band used in the 5GHz: UNII-2E
What’s the highest power used for the 5GHz in the US: UNII-2E or UNII-3 (should be UNNI-3 “UNII-3/ISM band is intended for outdoor bridge products and may be used for indoor WLANs as well”)
How do you measure the beam width for signal and power: 3db, 6db, 10db, ½, ¼, 1/6, 1/8, 1/10 : I think 3 & 1/2
Most overhead/administrative work required for network infrastructure: cloud, converged (Can’t remember other choices): I think autonomous….
Default tab of Cisco Prime Infrastructure for rogue APs: Security, General, CleanAir, (Can’t remember other choice): Security
Which controller provides excess of 20 GBps throughout: 8510, 5760, 5500, (can’t remember the other choice): 5760 have 60Gbps..

Thanks. I had the same answers accept for the autonomous but I think your right. Since it would require a ton of overhead to manage each autonomous AP. If you have/remember any more questions that you could share I would appreciate it.

ilsatch – Do you happen to know the answer to a question that asked about 802.11n and how to improve client reliability/connections. I cant remember the details of the questions but the answers had: Transmit form beaming, Max ratio combining, spatial multiplex and one other choice i cant remember.

this one?.

Which IEEE 802.11n client feature can combine the signal from multiple antennas and radio
chains to improve SNR?

No, it was worded differently and mentioned about having 802.11n clients and something about how to keep the reliability/connections for the non 802.11n devices.

mmm i dont remember that. For reliability i think you have 2 options, MRC or Transmit Beaforming.
But for non 802.11n clients you have ClientLink……

Do you remember this scenario?.

Antenna X ——4db loss—-2dbi gain——————-2dbi gain—-4db loss = -45dbm ??

with this options:

-118
118
-20
20
28….

20

How do you get 20?

ilsatch, where did you get those questions. those are the ones I really struggled with. I have failed exam twice, cheers for remembering them
do you remember the liscence questions
and the POE questions, in how does it effect ap 802.af something in those lines
Would really appreaciate it, plus do you remember anymore, thanks

I dont know if this is right but I calculated this way: -67db – -45dbm = 22 dbm
Then I calculated 22 +4 db (tx cable) -2 db gain tx antenne + 4db rx cable.
or the other way around 28 – 4 + 2 -4 = 22
But I find this question is a bad design. I find it hard to unterstand what they want.
Question? Why ist the distance of the to APs not mentioned at all?

ilsatch – the transmitter question the answer is 28

28 – 4 + 2 – 69 + 2 – 4 = -45

the -69 is the average loss from transmitter

ilsatch my answer is right

I agree with amin that the answer is 28.

Rx Power= Tx Power – Tx Cable + Tx Antenna – Free Space (-69) + Rx Antenna – Rx Cable

-45 = x – 4 + 2 – 69 + 2 – 4

-45 = x – 73

x = -45 + 73

x = 28

Joe any ideas about the POE questions and how POE affects the ap in 802af questions

the options are I recall

3x 3 mimo
disables interface
that’s all I can remember

Joe regarding the 802.11n question
I think this goes in the lines of how does 802.11n improve performance compared to 802.11b

Transmit form beaming, Max ratio combining, spatial multiplex and one other choice i cant remember

problem is it could be anything from those choices, anyone know which one it is

I choose Max ratio combining, because TX beamforming require feedback.

The question about how POE affects the ap in 802af questions – I think is 3×3 MIMO (But I selected this answer due to another member on this forum saying that was the answer, no clue if its actually correct).

As for the 802.11n question, I agree with you that it could be any of those choices.

I ‘m also leaning toward Max Ratio Combining as the answer

cheers guys, if you guys can remember anymore would be appreaciated and will try to remember some and post them, thanks

amin/Asti – Do you have any suggestions on the Mac OS questions?

I will have an update for you by thursday, I have a meeting with a guy who is CCNP wireless, I’m sure he will know the answer

Mac OS X machines are having issues accessing the wireless network. While working with TAC,
the administrator is asked to find the Mac laptop’s wireless adapter model and driver. Where
should the administrator look to find this information?
A. About This Mac > System Report
B. Control Panel > System
C. System Preferences > Network > Wi-Fi Adapter > Advanced
D. Control Panel > Networking > Adapters > Properties
Correct Answer: A

this is from the old wireless dumps, its definite A

not sure about the other mac question

Mac OS X machines ares having issues accessing the wireless network. While working with TAC, the administator is asked to find the mac laptop´s wireless adpater model and driver. Where should the administrator look to find this information?

1) About this Mac > System Report

The second one i choose

3) set de authentication configuration to use the desired setting under the system preferences network > advanced menu

but it was just a guess

Amin / Joe, where did you find that the average loss is -69?. Do you have any link?. Thanks!.

this is on the official ccna wireless syllabus – chapter 3

You should also be aware that the free space path loss is greater in the 5-GHz band than it
is in the 2.4-GHz band. In the equation, as the frequency increases, so does the loss in dB.
This means that 802.11b/g/n devices (2.4 GHz) have a greater effective range than 802.11a/n
(5 GHz) devices, assuming an equal transmitted signal strength. Figure 3-6 shows the range
difference, where both transmitters have an effective isotropic radiated power (EIRP) of 14
dBm and the effective range ends where a receiver’s received signal strength indicator (RSSI)
equals –67 dBm.

extract from chapter 3

Thanks!, and why you used -69 instead of -67?.

Amin, the other MAC OS question was…

A customer who recently implemented Mac OS X Yosemite finds that the laptops have benn autonegotiating the authentication protocols when performing RADIUS authentication to ISE. What must the administator do to statically set the correct setting for the Mac clients?

1) Select the SSID and change the setting to the desired configuration under Control Panel > Network > Wireless Network and export to the other machines.
2) Create a new network profile with the desired setting using the Apple iPhone configuration utility or profile manager and upload to all mac os x machines.*?
3) set de authentication configuration to use the desired setting under the system preferences network > advanced menu *
4) Delete the ssid and have the users go through the authentication process again, this time selectin the setting during authentication.

I must have read it somewhere but if you put -69 you will will see it equals to 28
which is one of the multiple choice answers

and if you use -67 you get 26 which is not one of the multiple choice answers

You dont take the dbi from the antenna on the recieving side into the calculation only the cable loss.

28 + 2 tx antenna -4 tx cable -4 rx cable = 22
67-45=22

ok dont listen to me. I was wrong. The calculation is in the bookpage 22:
20 dbm – 2loss + 4gain – 69freespaceloss +4gain -2loss = -45 dBm

You are right Asti, thanks!.

So the answer is 20 :)

I don’t get it loss is 4db not 2 – yes your right on the book loss is 2 db and answer is 20

however if loss is 4 db then I think answer is 28

And this one?.

A customer suspects that a continous transmitter is causing instability with the wireless clients that are operating on the 2.4GHZ wireless band. The customer is trying to determine which channel is being impacted by this transmitter. Which dashboard on the WLC GUI identifies this information?

1) Clear Air – Worst Air Quality Report
2) 802.1a/n – Air Quality reports
3) Statistics – Mobility Statistics
4) 802.11b/g/n – Interference Devices

http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-0/configuration/guide/c70/c70cleanair.html

Could be the #4 …or maybe the #1

1) Clear Air – Worst Air Quality Report – only shows the worst AP per Band.
Just copied from our 5508 Airos 8.0 controller:
