An engineer is configuring data and voice services to pass through the same port. The designated switch interface fastethernet0/1 must transmit packets using the same priority for data when they are received from the access port of the IP phone. Which configuration must be used?
- A. interface fastethernet0/1 switchport voice vlan dot1p
- B. interface fastethernet0/1 switchport priority extend cos 7
- C. interface fastethernet0/1 switchport voice vlan untagged
- D. interface fastethernet0/1 switchport priority extend trust
Refer to the exhibit. Which change to the configuration on Switch2 allows the two switches to establish an EtherChannel?
- A. Change the LACP mode to desirable
- 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
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?
- A. SW1(config-if)#switchport mode dynamic auto SW1(config-if)#switchport port-security SW1(config-if)#switchport port-security violation restrict
- 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

Which port type supports the spanning-tree portfast command without additional configuration?
- A. trunk ports
- B. Layer 3 sub interfaces
