CCNA 4

Which WLC interface provides out-of-band management in the Cisco Unified Wireless Network Architecture?

• AP-Manager

• service port

• dynamic

• virtual

Refer to the exhibit. The network engineer is configuring a new WLAN and is told to use a setup password for authentication instead of the RADIUS

servers.

Which additional set of tasks must the engineer perform to complete the configuration?

• Disable PMF Enable PSK Enable 802.1x

• Select WPA Policy Enable CCKM Enable PSK

• Select WPA Policy Select WPA2 Policy Enable FT PSK

• Select WPA2 Policy Disable PMF Enable PSK

Which mode must be set for Aps to communicate to a Wireless LAN Controller using the Control and Provisioning of Wireless Access Points

(CAPWAP) protocol?

• route

• bridge

• lightweight

• autonomous

Which switch technology establishes a network connection immediately when it is plugged in?

• PortFast

• BPDU guard

• UplinkFast

• BackboneFast

Which command on a port enters the forwarding state immediately when a PC is connected to it?

• switch(config)#spanning-tree portfast default

• switch(config)#spanning-tree portfast bpduguard default

• switch(config-if)#spanning-tree portfast trunk

• switch(config-if)#no spanning-tree portfast

If a switch port receives a new frame while it is actively transmitting a previous frame, how does it process the frames?

• The new frame is delivered first, the previous frame is dropped, and a retransmission request is sent

• The previous frame is delivered, the new frame is dropped, and a retransmission request is sent

• The new frame is placed in a queue for transmission after the previous frame

• The two frames are processed and delivered at the same time

Refer to the exhibit. The entire MAC address table for SW1 is shown here:

What does SW1 do when Br-4 sends a frame for Br-2

• It performs a lookup in the MAC address table for Br-4 and discards toe frame due to a missing entry

• It floods the frame out or all ports except on the port where Br-2 is connected

• It Inserts the source MAC address and port into the forwarding table and forwards the frame to Br-2.

• It maps the Layer 2 MAC address for Fa0/3 to the Layer 3 IP address and towards the frame.

Which statement about Link Aggregation when implemented on a Cisco Wireless LAN Controller is true?

• To pass client traffic two or more ports must be configured

• The EtherChannel must be configured in ג€mode active €

• When enabled, the WLC bandwidth drops to 500 Mbps

• One functional physical port is needed to pass client traffic

Refer to the exhibit. An engineer is configuring an EtherChannel using LACP between Switches 1 and 2.

Which configuration must be applied so that only Switch 1 sends LACP initiation packets?

• 
• 
• 
• 

Refer to the exhibit. The entire Marketing-SW1 MAC address table is shown here:

What does the switch do when PC-4 sends a frame to PC-1?

• It performs a lookup in the MAC address table and discards the frame due to a missing entry.

• It maps the Layer 2 MAC address to the Layer 3 IP address and forwards the frame.

• It inserts the source MAC address and port into the table and forwards the frame to PC-1.

• It floods the frame out of all ports except on the port where PC-1 is connected.
