Refer to the exhibit. It belongs to a Cisco IOS AP with just one radio. This portion of configuration refers to a multiple SSID/VLAN configuration. Which statement is correct?
Refer to the exhibit. It belongs to a Cisco IOS AP with just one radio. This portion of configuration refers to a multiple SSID/WLAN configuration. Which statement is correct?
The configuration does not allow for non-corporate clients to connect to any SSID Guest traffic.There fore will not allowed.
#39;mbssid guest-mode#39; is used to allow broad cat of multiple SSIDs on the radio interface. No other #39;mbssidquot; commands are needed to achieve this functionality.
The AP must have subinterfaces 80,81,and 82 configured on the Radio 0 and Ethernet interfaces.
The SSID quot;EAPquot; will allow clients to connect to it using any EAP authentication method such as EAP-TLS.
Answer: C Explanation:
Consider the association process of a wireless client to an SSID. Drag and drop the client actions from the left into the correct order of operation on the right.
802.11 probe request 802.11 association request EAPol key message 2 802.11 authentication request EAP identity response
Step1 ——-Step1 802.11 probe request
Step2 ——-Step2 802.11 authentication request Step3 ——-Step3 802.11 association request Step4 ——-Step4 EAP identity response
Step5 ——-Step5 EAPol key message 2

On a Cisco autonomous AP, the maximum number of attempts to send a packet (packet retries) is set to 32 by default. Which statement about the result when the AP has tried to send a packet for that number of attempts and no response is received from the client is true?
The access point drops the packet.
The client MAC address is excluded for 60 seconds.
The access point resets the radio interface.
The access point disassociates the client.
Packet Retries amp; Max-Retries I mrn-cciew https://mrncciew.com/2013/06/16/packet-retries-max-retries/
In Autonomous(IOS) AP, you can configure number of attempts the wireless device makes to send a packet before giving up amp; dropping the packet. There are two ways of configuring this feature. One method for best effort (priority value 0) traffic amp; another method for non- best effort (priority value 1-7)
Best-effort Traffic (packet retries command)
N on-Best-effort Traffic (packet max-retries command ) CLI default:
packet retries 32 drop-packet channel width 40-above channel dfs station-role
root rts retries 32 cfg:
Configuring the Maximum Data Packet Retries
The maximum data retries setting determines the number of attempts the makes to send a packet before giving up and dropping the packet. The default setting is 32. Beginning in privileged EXEC mode

You are setting up a Cisco access point in repeater mode with a non-Cisco access point as the parent and you use this interface configuration on your Cisco access point.
You are getting the following error message. Which reason for this issue is true?
Tll-4-CANT_A$S0C:lnterface DotllRadioO, cannot associate:No Aironet Extension IE.
quot;dotll extension aironetquot; is missing under the interface DotllRadio 0 interface When repeater mode is used, unicast-flooding must be enabled to allow Aironet IE communications.
The parent AP MAC address has not been defined.
Repeater mode only works between Cisco access points.

You have received a new Cisco 5760 Controller and have gone through the initial startup wizard. You are now trying to add APs to the controller, but these are not joining.
Which three checks should you do next? (Choose three.)
Check that the radios are not in a shutdown state.
Check the country code of the controller. The APs do not join the controller if the country code does not match.
Check that the correct time is set on the controller.
Check that option 53 has been set in the DHCP scope.
Check that the controller has enough AP licenses.
Check that the controller has been configured with the correct hostname. Otherwise, DNS resolution fails.

Which two effects does TSPEC-based admission control have as it relates to WMM clients? (Choose two)
Deny clients access to the WLAN that do not support WMM.
Allow access only for VoWLAN traffic when interference is detected.
Enforce airtime entitlement for wireless voice applications.
Ensure that call quality does not degrade for existing VoWLAN calls.
Deny clients access to the WLAN if then do not comply with the TERP standard.
