1.

What is the objective of the Cisco Compatible Extensions program?

to provide access to proprietary Cisco IOS software code in order to expand the number of vendors writing

wireless code to provide Cisco engineers with the opportunity to certify that any wireless devices that are made by thirdparties are compatible with Cisco wireless products to provide customers with a broad range of WLAN client devices that have been tested for interoperabilitywith Cisco Aironet innovations to provide third parties with Cisco hardware in order to encourage the development of radical innovation inthe area of wireless

2.

Which two statements correctly describe features of Lightweight Access Point Protocol (LWAPP)? (Choose
two.)
Select 2 response(s).

Data traffic between an access point and a controller is encrypted within LWAPP. Control traffic between an access point and a controller is encrypted within LWAPP. Data traffic between an access point and a controller is encapsulated within LWAPP. Layer 3 mode packets are transmitted in TCP frames. VLAN tagging and QoS markings are applied at the access point.

3.

Why is BPDU guard an effective way to prevent an unauthorized rogue switch from altering the spanning-tree topology of a network?

BPDU guard can guarantee proper selection of the root bridge. BPDU guard can be utilized along with PortFast to shut down ports when a switch is connected to the port BPDU guard can be utilized to prevent the switch from transmitting BPDUs and incorrectly altering the rootbridge election. BPDU guard can be used to prevent invalid BPDUs from propagating throughout the network.

4.

Which statement is true about voice VLANs?

The voice VLAN feature is enabled by default. When the voice VLAN feature is enabled, all untagged voice and data traffic is sent through the voiceVLAN. The default CoS value is 1 for incoming voice and data traffic. The IP phone overrides the priority of all incoming data traffic (tagged and untagged) and sets the CoSvalue to 0.

5.

For what purpose is the command config network webmode enable used?

to allow HTTPS access to the WLAN controller to allow HTTP access to the WLAN controller to allow SSH access to the CLI of the WLAN controller to allow SSL access to the CLI of the WLAN controller

6.

When an attacker is using switch spoofing to perform VLAN hopping, how is the attacker able to gather information?

The attacking station uses DTP to negotiate trunking with a switch port and captures all traffic that is allowed on the trunk The attacking station tags itself with all usable VLANs to capture data that is passed through the switch,regardless of the VLAN to which the data belongs. The attacking station will generate frames with two 802.1Q headers to cause the switch to forward the frames to a VLAN that would be inaccessible to the attacker through legitimate means. The attacking station uses VTP to collect VLAN information that is sent out and then tags itself with thedomain information in order to capture the data.

7.

Which statement is true about the Lightweight Access Point Protocol (LWAPP)?

The control traffic between the client and the access point is encapsulated with the LWAPP. Data traffic between the client and the access point is encapsulated with LWAPP. Authentication, security, and mobility are handled by the access point. Real-time frame exchange is accomplished within the access point.

8.

With Cisco Express Forwarding, prefixes that require exception processing can be cached with one of which
four special adjacencies. (Choose four.) Select 4 response(s).

drop null glean kick discard

9.

What does the auto qos voip cisco-phone command do?

If a Cisco IP phone is attached, the switch trusts the CoS. The switch assigns a CoS value of 5 to incoming packets. It turns on STP to see if a Cisco IP phone is attached. If a Cisco IP phone is attached and removed, the switch continues to trust the CoS values as long as theswitch is not rebooted. It disables the trust boundary feature because the switch knows a Cisco IP phone is attached.

10.

A network administrator would like to configure 802.1x port-based authentication, however, the client workstation is not 802.1x compliant. What is the only supported authentication server that can be used?

TACACS with LEAP extensions TACACS+ RADIUS with EAP extensions LDAP
