first off it's direct-sequence spread spectrum
secondly the data rate is achieved by combining the modulation with coding
thirdly ofdm rates are much higher then DSSS except for the 6Mbps data rate
so I don't understand this question
cisco sells
Power Levels 2.4 Ghz:20dbm 5.8 Ghz:17dbm 2.4 Ghz:28dbm 5.8 Ghz:28dbm
virtual interface is for mobilty, dhcp relay and guest web auth.
mgmt int is for inband
The aWGB connects only to upstream Cisco APs, and the AP sees multiple Ethernet clients.
uWGB It allows bridging to upstream non-Cisco APs and appears as a
single client.
drag and drop-vowlan(2),management(1),foundation(3) read these topics..
1.Know how ip is assigned from WLC or through external dhcp server..
2.check the status of the dhcp is not enabled.. so its getting ip from switch..
3.wireless n channel is " 149 " which is not correct..
Mostly all the questions are logical.
this dump is valid..
thanks all for ur valuable comments..
Answer:
• Commands available during a Telnet or SSH session include debug, disable, enable, help, led,
login, logout, more, no debug, show, systat, undebug, where.
To avoid potential conflicts and security threats to the network, the following commands are
unavailable while a Telnet or SSH session is enabled: config terminal, telnet, ssh, rsh, ping,
traceroute, clear, clock, crypto, delete, fsck, lwapp, mkdir, radius, release, reload, rename,
renew, rmdir, save, set, test, upgrade.

all new questions were discussed by this comments, read careful
thanks a lot to meh123, good luck to all testtaker.
some tips, there is a lot question on WCS and Drag and drop,
please study on Delete, clear and acknowledge function in Alarm summary in WCS <- one of the drag and drop question ,
another drag and drop question;
what are the function you are able to do in the Lightweight AP when you SSH and Telnet in,
remember you are not able to config t, enable, you can show, clear, not sure debug ( but i answer debug)
good luck to those who are taking exam ...
Also few new Drag & drop can't remember . Learn drol3 drag & drop are true and correct.
New Question d&d
IBSS/OPEN----------THREE BOX WITH SHIELD
IBSS/SECURE ----- THREE BOX WITHOUT SHIELD
BSS/SECURE ------ 5 BARS WITHOUT SHIELD
BSS/OPEN ------ 5 BARS WITH SHIELD
Other question troubleshotting screenshoot config, in a question the opcion correct is connect http://10.10.10.10 to wlan
Other d&d
foundation (3)
vowlan (2)
managament (1)
Other question tshoot with screenshoot about dhcp ip, in figure you can see the group interface the correct alternative is the cliente recived ip from segment that pertenencie to group.
Final new d&d about process one cliente and ap a and b this same this is correct order
1- Client sends probe request.
2- Access points (A/B) send probe response. Client evaluates
access point response, selects best access point.
3- Client sends authentication request to selected access point (A).
4- Access point (A) confirms authentication and registers client.
5- Client sends association request to selected access point (A).
6- Access point (A) confirms association and registers client.
Could you please share with answers for
1st question, dhcp collision, WLC and L3 both define DHCP scope, which the AP will get for operate?
A WLC, B Switch, C route robin D Not getting ip (subnet override) E Static IP required
as well ass for Sean's Q.6-9
What do you mean when you said troubleshooting ?
Is that a sim ? with some emulated termianl and everything like you have on the CCNA ??
Thanks
Passed With 950 , The Dump is Valid 100% but the answers sometimes not correct , there are 3 troubleshooting scenarios ( one about native vlan mismatch , one about Client not connected due to WPA2 - TKIP mismatch ) , and there is a totally new question about smthn i don't know about :D all of the rest questions are the same. Good Luck
Anon: Gratz and cheers!
John: sorry for late reply, actually is WLC will lease for AP, host get ip from switch
the correct is :
which the AP will get for operate?
A WLC,
Conclusion: I would say this dump is still valid, plus those Tshoot questions (one was with the Win 7 bars)
GL to all !
5 bar with a star logo,
threebox with yellow shield logo,
threebox without yellow shield logo,
5 bar with yellow shield logo,
5 bar without yellow shield logo,
star means no connection yet, yellow shield is means security open(without password required), 5 bar means connect with BSS / AP, 3 box means connect with IBSS / ad hoc
but if you r confident and exp enough, I think should be ok, coz the answer is quite straight forward and common sense.
Looks like new questions appeared recently
When can we expect a new file?
Apple: Damn it, CISCO is killing us, ur the unlucky 1,haiz..
so 1st question, dhcp collision, WLC and L3 both define DHCP scope, which the AP will get for operate?
A WLC, B Switch, C route robin D Not getting ip (subnet override) E Static IP required
2nd question, why old 2.4 spectrum host unable to connect to the AP?
*take note the screenshot is only configured with WPA2/TKIP, security issue
3rd question, why the host is unable to use .11n speed?
*take note the WLC configuration on a/n page
4th question, host is unable to connect, why?
*take note the hex key required to added on..
5th question the conflict of choosing ap /probe issue, topology AP 1<-> host <-> AP 2, *take note answer in sequence steps, broadcast bss -> both ap response -> choose the suitable AP to connect in within -> send request for associate AP1 -> authentication request -> authentication reply -> send probe to AP
6th question DND of basic of 802.11, management of 802.11, VoWLAN
7th question WLC administration page, how to configure bla bla bla
8th question WLC administration page, how to determine if AP is connected?
9th question WLC administration page, Base on the monitoring page which is most suitable for the explanation as below? (from answers)
10th question D&D of windows 7 wireless logo, ibss open -> three box with a shield, ibss secure -> three box without shield, bss open -> 5 bar with a shield, bss secure -> 5 bar without shield
and alot more, i cant hardly remember, but lucky I passed with 870, not easy if you are not familiar in cisco WLAN env/exp...
i plan on taking my exam tomorrow. it will help to review them.
anyway thanks for the corrections and the dump...
