PUT

DELETE

COPY

POST

SET

2. Refer to the exhibit.

Which option describes what this sequence of commands achievers on a Cisco Autonomus AP?

This example shows how to permit SNMP access to all objects with read-only permission to only those three specific IP addresses using the community string public. The access point also sends config traps to the hosts 192.180.1.111 and 192.180.1.33 using SNMPv1 and to the host 192.180.1.27 using SNMPv2

The community string public is not sent with the traps because is the default community value.

The community string public is not sent with the traps.

This example shows how to permit any SNMP manager to access all objects with read-only permission using the community string public. The access point also sends config traps to the hosts 192.180.1.111 and 190.180.1.33 using SNMPv1 and to the host 192.180.1.27 using SNMPv2

The community string public is not sent with the traps as this is the default community value.

You are getting the following error message. Which reason for this issue true?

%DOT11-4-CANT_ASSOC Interface Dot 11 Radio0. Cannot associate NO Aironet Extension IE.

“dot11 extension” is missing under the interface Dot11Radio 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 point.

4. 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.

5. You are installing Converged Access controllers that run Cisco IOS-XE and you are ready to implement QoS. From the below, choose all the possible QoS target levels that would apply to downstream traffic (toward the client)?

Client, SSID, Radio, Port

Client, SSID, Radio

Client, Radio

Client, SSID

6. DRAG DROP

Drag and drop the CAPWAP event on the left into the order in which they occur on the right during the WLC discovery and join processes.

7. Which memchanism incorporates the channel capacity into the CAC determination and gives a much more accurate assessment of the current call carrying capacity of the AP?

Static CA

Reserved roaming bandwidth (%).

Expedited bandwidth.

Metrics collection.

Load-based A

Max RF bandwidth (%).

Admission control.

8. On a Cisco 5760 WLC, which of the below is not part of the initial setup script?

Wireless management interface

Host name

HTTP server login account

SNMP Network Management

NTP server

Enable password

Default routing protocol

9. A Cisco Unified 7925G Wireless IP Phone is operating on the 5 GHz band and transmitting at a power level of 40 mW. Which configuration must be done on the controller to avoid one-way audio?

In DCA, enable UNH-1 channels only.

Set the maximum power level assignment to 26 dBm.

In DCA, enable UNII-II channels only.

Set the maximum power level assignment to 16 dBm.

10. Which two effects does TSPEC-based admission control have as it relates to WMM clients?(Choose two.)

Deny clients access to the VLAN that do not support WM

Allow access only for VoWLAN traffic when interference is detected.

Enforce airtime entitilement for wireless voice applications.

Ensure that call quality does not degrade for existing VoWLAN calls.

Deny clients access to the WLAN if they do not comply with the TERP standard.

11. Your customer has a Cisco Unified Wireless Network running AireOS 8.0 and wants to learn about the FlexConnect mode that is available on his APs. Which two statements are true? (Choose two.)

A newly connected AP can be booted in FlexConnect mode.

When an AP is changed from Local mode to FlexConnect mode, a reboot is required.

Enhanced FlexConnect mode allows to enable wIPS on FlexConnect APs.

When an AP is changed from Local mode to FlexConnect mode, reboot is not required.

Using CCKM with FlexConnect APs requires the use of FlexConnect Groups.

FlexConnect was previously know as "H-TEEP"

12. Refer to the exhibit.

You are troubleshooting location accuracy problems on a customer deployment. You have done the wireless design and you are sure that the As are correctly placed on the Cisco Prime map. Everything is correctly synchronized between WLC, PI, and MSE but, you are sometimes getting elements tracked on the wrong floor. After you get this debug output from MSE, which step is next?

Reduce the confidence level on MSE when the last heard value is higher than 150 seconds.

Run a new calibration model and ensure that it is applied on the floor.

Discard RSSI values lower than C 75 dbm.

Check it the AP with MAC address 001c 0f 4c 45 60 is physically located on the floor where the element was wrongly located and if the inter-floor attenuation is weak.

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

The backhaul client access feature cannot be enabled on a RAP that is, a RAP does not allow clients on its 302.11a radio.

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.

A MAP/RAP must be authorized by either PSK or EAP before joining a controller in bridge mode

RADIUS and Local authentications are supported with both PSK and EA

VLAN tags are always forwarded across Mesh links.

14. Which three conditions can trigger a client exclusion policy?(Choose three.)

Excessive 802.11 probe request failures

Excessive 802.lx authorization failures

IP theft or IP reuse

Excessive 802.lx authentication failures

Excessive 802.11 association failures

Excessive 802.11 packet retries

15. Which two features were added as part of the 802.llh amendment?

Dynamic Frequency Selection and Direct Link Setup.

Dynamic Frequency Selection and Transmit Power control.

Dynamic Frequency Selection and Wireless Performance Prediction.

Dynamic Frequency Selection and Inter-Access Point Protocol.

16. VLAN Trunking Protocol is a Cisco proprietary protocol that propagates the definition of VLANs over the local area network. Which two statements are true?(Choose two.)

VTP requires access mode interfaces to propagate.

VTP requires trunk mode interfaces to propagate.

VTP transparent mode forwards VTP packets and can act as a client or a server.

VTP config revision increases base on switch uptime.

When Cisco switches are started from scratch, they are in server mode and their domain is set to null.

17. Which two statements are true about adding Identity Services Engines 1.3 to Prime Infrastructure 2.2?(Choose two.)

You need to use super user credentials on ISE for PI integration to work.

If you add two ISEs, one should be primary and the other should be standby.

Configuration templates within PI can be used to set up IS

A maximum of three ISEs can be added to P

18. Which two statements about VXLAN are true?(Choose two.)

VXLAN overcomes the 802.1Q virtual LAN address space limitation.

VXLAN is an encapsulation method used to create a Layer 3 overlay network

VXLAN uses the Spanning Tree Protocol for loop prevention.

VXLAN is a Cisco proprietary standard.

VXLAN can be used to enforce Layer 2 isolation in a multitenant infrastructure.

19. Which statement about Wired Guest Access is true?

The guest traffic can terminate on the foreign WLC, but egress interface must be defined on the guest SSID

Wired Guest Access is not supported in the Cisco 5760 WLC

The wired guest traffic terminates only on the anchor Cisco WLC

The Cisco 5760 WLC supports Wired Guest Access only in conjunction with the converged access switches.
