When a FlexConnect AP is in the “local authentication, local switching†state, it handles client authentication and switches client data packets locally. This state is valid in standalone mode and connected mode. Which three statements about a FlexConnect AP are true? (Choose three.)

  • A. In connected mode, the AP provides minimum information about the locally authenticated client to the controller. This information is not available to the controller: policy type, access VLAN, VLAN name, supported rates, encryption cipher.
  • B. In connected mode, the access point provides minimal information about the locally authenticated client to the controller. However, this information is available to the controller, policy type, access VLAN, VLAN name, supported rates, encryption cipher.
  • C. Local authentication is useful where you cannot maintain a remote office setup of a minimum bandwidth of 128 kbps with the round-trip latency no greater than 100ms and the maximum transmission unit no smaller than 576 bytes.
  • D. Local authentication is useful where you cannot maintain a remote office setup of a minimum bandwidth of 128 kbps with the round-trip latency no greater than 150ms and the maximum transmission unit no smaller than 500 bytes.
  • E. Local authentication is connected mode does not require any WLAN configuration.
  • F. Local authentication can be enabled only on the WLAN of a FlexConnect AP that is in local switching mode.


Answer : ACF

Explanation:
In connected mode, the access point provides minimal information about the locally authenticated client to the controller. The following information is not available to the controller: â€" Policy type â€" Access VLAN â€" VLAN name â€" Supported rates â€" Encryption cipher
Local authentication is useful where you cannot maintain a remote office setup of a minimum bandwidth of 128 kbps with the round-trip latency no greater than
100 ms and the maximum transmission unit (MTU) no smaller than 500 bytes. In local authentication, the authentication capabilities are present in the access point itself. Local authentication reduces the latency requirements of the branch office.


Note Local authentication can only be enabled on the WLAN of a FlexConnect access point that is in local switching mode.

Which statement about a Cisco Mesh Network when a radar event is detected by the MAP on a mesh tree when coordinated channel change is enabled is true?

  • A. The MAP immediately stops transmission on the current channel and joins the parent after 30 minutes after the channel is marked as clean.
  • B. The MAP propagate radar event information to the RAP in the same BGN, searches for a different parent working on a non-dfs channel, and joins there.
  • C. The MAP continues transmission of the beacons and probes for 10 seconds after the radar detection and suspends operation for the next 30 mins.
  • D. The MAP propagates the radar event information to the RAP and the whole sector moves to the new channel.


Answer : A

Explanation:
If the mesh access point does detect radar, the controller and the mesh access point both will retain the channel as the configured channel. The controller retains it in volatile memory associated with the mesh access point, and the mesh access point has it stored in its flash as configuration. After the 30 minute quiet period, the controller returns the mesh access point to the static value, regardless of whether the mesh access point has been configured with a new channel or not. In order to overcome this, configure the mesh access point with a new channel, and reboot the mesh access point.

Which action is needed to edit the settings of an RF profile?

  • A. Remove the desired RF profile from all AP groups.
  • B. RF profiles cannot be edited. They must be removed and recreated with the desired values.
  • C. Disable both radio networks.
  • D. Disable custom power level settings for all APs within the group to which the profile linked.


Answer : A

Explanation:

Your customer is having wireless VoIP problems. When the Cisco 7925 phones roam from AP1 to AP2, the voice drops out and comes back. The phones are set up for PEAP/WPA1-AES with CCKM to an external RADIUS server. The APs and WLAN are set up in FlexConnect mode. Which statement explains the issue?

  • A. PEAP with WPA-AES is not supported with Cisco Centralized Key Management, use EAP-FAST.
  • B. The APs have been added to the FlexConnect group.
  • C. The APs have not been added to the FlexConnect group.
  • D. PEAP with WPA2-AES is not supported with Cisco Centralized Key Management, use LEAP.


Answer : C

Explanation:
Fast Secure Roaming via CCKM is supported only among APs within the same FlexConnect group. As the number of APs within a Flex group is limited (for example, on the 5508 WLC, to 25 APs), FlexConnect is not suited to large deployments.

Which two statements about deploying a mesh network by MAPs and RAPs are true on AireOS 8.0? (Choose two.)

  • A. The backhaul client access feature cannot be enabled on a RAP that is, a RAP does not allow clients on its 802.11a radio.
  • B. RADIUS and Local authentications are supported with both PCK and EAP.
  • C. The three main types of mesh type under the neighbor information are neighbor, parent, and child. For types default neighbor, default parent, and default child, default is used when the neighbor BGN is not known or different from the current AP BGN if the strict matching BGN feature is disabled.
  • D. A MAP/RAP must be authorized by either PSK or EAP before joining a controller in bridge mode.
  • E. VLAN tags are always forwarded across Mesh links.


Answer : BC

Explanation:

You are working on a deployment that uses two Cisco APs as wireless bridges. One of the bridges is configured as a root bridge and the second bridge is configured as a nonroot bridge. Client A associates to the root bridge and client B associates to the nonroot bridge. Which two statements about this scenario is true? (Choose two.)

  • A. Only one device can connect to the Ethernet port of a noonroot bridge.
  • B. For two bridges to communicate with each other, one of the bridges must be in root mode and the other bridge must be in nonroot mode.
  • C. In point-to-multipoint bridging, WGB is not recommended with the root bridge.
  • D. Two bridges that are in root mode can talk to each other.
  • E. The default setting of a bridge is nonroot bridge.


Answer : B

Explanation:
For two bridges to communicate with each other, one of the bridges should be in rootmode and the other bridge must be in non-rootmode.
The default setting of a bridge isroot. Therefore, two bridges that are in rootmode cannot talk to each other.

With the introduction of Mdns Policies in AireOS release 8.x, the administrator can configure to identify who uses the Bonjour service instances and in which location. Based on user 802.1x authentication, a AAA server/ISE can be configured to return which two possible values in the form of a “CISCO-AV-PAIR�
(Choose two.)

  • A. Bonjour-profile
  • B. user-ID
  • C. client-location
  • D. client-role
  • E. user-role


Answer : AE

Explanation:
Explanation:With introductionof the Bonjour policies in the release 8.0, the administrator can configure to identify who uses the Bonjour service instances and in what location (all this applies to the same WLAN). With introduction of the Bonjour policies, the administrator does not need to create multiple WLANs to select which services are allowed or should be used on specific WLAN. Based on user 802.1x authentication, the AAA server or ISE can be configured to return USER-
ROLE or BONJOUR-PROFILE in the form of the “CISCO-AV-PAIRâ€. This value gets plumbed into the policy created on the wireless controller. Based on the user authentication, a configured policy and profile are applied to a specific user on the same WLAN.
