Question 292
Refer to the exhibit. Which change to the configuration on Switch2 allows the two switches to establish an EtherChannel?

B. Change the protocol to PAgP and use auto mode
C. Change the LACP mode to active
D. Change the protocol to EtherChannel mode on
Question 293
Refer to the exhibit. An engineer must configure the interface that connects to PC1 and secure it in a way that only PC1 is allowed to use the port. No VLAN tagging can be used except for a voice VLAN. Which command sequence must be entered to configure the switch?

B. SW1(config-if)#switchport mode nonegotiate SW1(config-if)#switchport port-security SW1(config-if)#switchport port-security maximum 1
C. SW1(config-if)#switchport mode access SW1(config-if)#switchport port-security SW1(config-if)#switchport port-security mac-address 0050.7966.6800
D. SW1(config-if)#switchport mode dynamic desirable SW1(config-if)#switchport port-security mac-address 0050.7966.6800 SW1(config-if)#switchport port-security mac-address sticky
Question 294
Which protocol must be implemented to support separate authorization and authentication solutions for wireless APs?

B. TACACS+
C. 802.1X
D. Kerberos
Question 295
Which port type supports the spanning-tree portfast command without additional configuration?
A. trunk ports
B. Layer 3 sub interfaces
C. Layer 3 main interfaces
D. access ports
Question 296
Refer to the exhibit. What are two conclusions about this configuration? (Choose two.)
A. The spanning-tree mode is Rapid PVST+
B. This tea root bridge
C. The spanning-tree mode is PVST+
D. The designated port is FastEthernet 2/1
E. The root port is FastEthernet 2/1
Question 297
A Cisco engineer must configure a single switch interface to meet these requirements: - Accept untagged frames and place them in VLAN 20, - Accept tagged frames in VLAN 30 when CDP detects a Cisco IP phone. Which command set must the engineer apply?
A. switchport mode dynamic desirable switchport access vlan 20 switchport trunk allowed vlan 30 switchport voice vlan 30
B. switchport mode access switchport access vlan 20 switchport voice vlan 30
C. switchport mode dynamic auto switchport trunk native vlan 20 switchport trunk allowed vlan 30 switchport voice vlan 30
D. switchport mode trunk switchport access vlan 20 switchport voice vlan 30
Question 298
What does a switch use to build its MAC address table?
A. VTP
B. DTP
C. ingress traffic
D. egress traffic
Question 299
Refer to the exhibit. The EtherChannel is configured with a speed of 1000 and duplex as full on both ends of channel group 1. What is the next step to configure the channel on switch A to respond to but not initiate LACP communication?
A. interface range gigabitethernet0/0/0-15 channel-group 1 mode on
B. interface range gigabitethernet0/0/0-15 channel-group 1 mode desirable
C. interface port-channel 1 channel-group 1 mode auto
D. interface port-channel 1 channel-group 1 mode passive
Question 300
Which command entered on a switch configured with Rapid PVST+ listens and learns for a specific time period?
A. switch(config)#spanning-tree vlan 1 priority 4096
B. switch(config)#spanning-tree vlan 1 hello-time 10
C. switch(config)#spanning-tree vlan 1 max-age 6
D. switch(config)#spanning-tree vlan 1 forward-time 20
