It does appear to be CDF.

Express Security Limitations

Because the Express Security page is designed for simple configuration of basic security, the options available are a subset of the access point security capabilities. Keep these limitations in mind when using the Express Security page:

•You cannot edit SSIDs. However, you can delete SSIDs and recreate them.
•You cannot assign SSIDs to specific radio interfaces. The SSIDs that you create are enabled on all radio interfaces. To assign SSIDs to specific radio interfaces, choose Security > SSID Manager.
•You cannot configure multiple authentication servers. To configure multiple authentication servers, click Security > Server Manager.
•You cannot configure multiple WEP keys. To configure multiple WEP keys, click Security > Encryption Manager.
•You cannot assign an SSID to a VLAN that is already configured on the access point. To assign an SSID to an existing VLAN, choose Security > SSID Manager.
•You cannot configure combinations of authentication types on the same SSID (such as MAC address authentication and EAP authentication). To configure combinations of authentication types, choose Security > SSID Manager.

Thanks foxx, I also thought C D F to be the right answer on #42.

Any idea on this question?
Which three WLC debug commands are appropriate to troubleshoot a wireless client that is
associated to an AP? (Choose three.)
A. debug capwap
B. debug mac addr
C. debug dot11
D. debug dhcp
E. debug ap
F. debug dtls
It is showing b c d as correct answer everywhere, but I am pretty sure you can not use debug mac addr, rather it is debug client . In that case A C D should be correct answer. What do you think?

What is the approximate time difference for a client to perform Intracontroller roaming compared to intercontroller roaming?
a. 1 ms
b. 10 ms
c. 20 ms
d. 30 ms

How come 10 ms is the right answer?
I was watching CBT nugget video by Keith Barker. Intercontroller roaming takes around 50 ms, and intracontroller takes around 10 ms. so the time difference should be roughly 40 ms. Anyone wanna share thoughts on this please?

@Tintin #4
The answer does appear correct to me: BCD

“Debug mac addr” is really a filter for subsequent debug commands. You would enter “debug mac addr xx:xx:xx:xx:xx:xx” then follow with other debug commands to filter just that mac address in the debug dump (in this case, debug dot11 and debug dhcp).

@Foxx
I c.

Have you checked Guardians comment on this question on page 60.

@Tintin #5
According to the official cert guide:

Intracontroller roaming:
“Thanks to the simplicity, an intracontroller roam takes less than 10 ms to complete”

Intercontroller Layer 2 roam:
“The client can keep its same IP address, and the roam is fast (usually less than 20 ms).”

I wasn’t able to find a speed for an intercontroller layer 3 roam in the guide, unless I’m just overlooking it somewhere. Looks like 10ms would be the correct answer.

Review the IMM document posted on the last page

You might see number 216 on your test. I did

@titan – foxx is correct – I saw that also

When a WLC uses/integrates (don’t really remember) several WLAns, which interface is created?
A. Service port
B. Virtual
C. Management
D. Dynamic
E. Can’t remember

Dynamic

@foxx helped with this one. I remember something similar – keep in your mind Dynamic and WLC – cant remember the question

@Foxx
#8, thanks for explaining. If you consider layer 2 intercontroller roaming, then 10 ms has to be the right answer. I was thinking of layer 3 intercontroller roaming, so got confused.

@Bob
#9
Right answer to 216 is access, trunk and port-channel trunk; Am I right?

@guardian Please send me 437 Q dumps (shy . beau gmail . com ) . Thanks

Which portion of a WLAN deployment can WLC message logs help to troubleshoot?

A. RF issues

B. encryption issues between APs and clients

C. configuration verification issues

D. infrastructure and client Issues

E. AP placement issues

I am seeing varied answers for this questions, could someone please shed light on this one?

What three components must be the same on a controller and the radius server when adding radius server to WLC?
a. User name
b. Shared secret
c. Index priority
d. Port number
e. IP address
f.Network mask

Anyone knows the right answer? Please comment.

@guardian
Received thanks for your help :)

@Tintin
For post #14 I think D is the right choice.

@Tintin
#15 B and E must be same

@Bob: Congratulations!!!! That was a great job and thanks for the additional inputs.

@Tintin and guardians: Goodluck guys. Hope you will make it too.

@Foxx: Thanks for your continued support man. That’s a lot of help.

#15
Needs 3 correct answers. Port number and shared secret are needed to be same for sure. I am confused between Subnet mask and IP address. In my opinion, subnet mask looks more appropriate to me as I won’t expect the WLC and the radius server having the same IP address. In the dump, it is showing IP address as one of the correct answer.

Foxx, please share your expertise mate :) many thanks in advance.

@Tintin
Should be IP, port number, and shared secret.

When you go to Security, RADIUS, Authentication, you’ll enter the IP of the AAA server, the secret used on both, and the port number.

The index priority can be set if you really want it, but it just picks the next number.
There is no username to set.
There is no subnet mask to set; we’re not doing routing on the WLC, just pointing to an IP.

Thanks Foxx :)
There is a new question, What interference you will see when conducting a site survery (Choose 3)-
A. Microwave Ovens
B. Analog Wireless Camera
C. AdHoc Hotspot
D. Bluetooth headset

I thought it should be A B D, but in many places I am seeing Adhoc hotspot as one of the correct answer instead of Bluetooth headset. Any idea why is that?

@Tintin Interference term is used for non 802.11 devices, so Adhoc hotstop is not an interference although it is an unwanted signal

Which CLI command is used on a Cisco WLC to troubleshoot mobility, rogue detection, and load- balancing
events?
A. debug dot11
B. debug capwap all
C. show dot11 details
D. show capwap details

@guardian
A, debug dot11

“To configure the debugging of 802.11 events, use the debug dot11 command.

debug dot11 { all | load-balancing | management | mobile | nmsp | probe | rldp | rogue | state} { enable | disable}

Please check your email, sent 437.

My exam is in 16 hours from now :(

Scared to death :(

Thanks .Best of luck .

@Tintin/guardian please share 437Q windewit365 @ outlook . com

sorry wimdewit365 @ outlook . com

@Tintin TKIP is not supported in 802.11n

@Guardian, the question is not quite appropriate. Apart from TKIP all the other options are valid to work with 802.11n. If you need to choose one option as a right answer, TKIP will be the most appropriate here.

What does the current European Telecommunications Standards Institute rule state is the 2.4-GHz maximum transmitter output power for point-to-point installations?

A. 16dBm
B. 17dBm
C. 20dBm
D. 30dBm
E. 36dBm

@Guardian would you choose b or c in this question

@Tintin
For post #37 I will chosse surely C since OCG said so

@Tintin it asks for slower connecrions, I think using CCMP is the best answer.

@Tintin/guardian
The max transmitter output power under ETSI is 17dbm. The EIRP maximum is 20dbm.

https://learningnetwork.cisco.com/docs/DOC-31396

That’s for both point-to-point and point-to-multipoint systems.

Hello guardian,

It would be great if you can share the dump file to tonnnywhyte @ gmaildotcom

Passed with 947 :) I was not sure until I saw the score that I am gonna pass. I used the cbt nugget videos extensively to learn the core concepts and it really helped. Skimmed through the OCG and read the CWNA book as well.

The last 15 pages of this forum, 411q and the IMM doc has been crucial in my preparation. I cant emphasize enough on going through the questions discussed in the last 15 pages of this forum, many of them appeared in my exam. None of the questions in my exam was totally new, wordings and options were quite different in majority of the questions though. But that challenge can easily be overcome with some common sense, general understanding of WiFi, concepts learned from CBT nuggets.
Massive thanks to Foxx and Guardian and everyone else in this forum for generously helping me out with so many questions I asked in last few weeks. Good wishes for all the future test takers in the forum.

Wow! Congratulations Tintin.

By the way, can you confirm if there are questions regarding AnyConnect and RRM? Thanks and congrats again.

Hello to all.
I did the exam on June 6 and unfortunately I did not pass it. The links that were presented in these pages are not useful x passing the exam.
I ask anyone who is aware of the sources needed to pass the exam 200-355.
There is no drag and drop, no laboratory simulation.
Please help me because without dump or exam simulators overcoming this rock is very difficult.
Thanks again to anyone who wants to help me.

I will add that the 441q link is also insufficient to pass the exam.

@Tintin
Superb. Congrats to you. I will try my chance by next week.

@Tintin
You mentioned about a CWNA book. What is it? Can you share pdf with me?
