A.       dynamic desirable (VTP domain A) to dynamic desirable (VTP domain A)

B.       dynamic desirable (VTP domain A) to dynamic desirable (VTP domain B)

C.       dynamic auto (VTP domain A) to dynamic auto (VTP domain A)

D.       dynamic auto (VTP domain A) to dynamic auto (VTP domain B)

E.        dynamic auto (VTP domain A) to nonegotiate (VTP domain A)

F.        nonegotiate (VTP domain A) to nonegotiate (VTP domain B)


Correct Answer: AF




Which two RSTP port roles include the port as part of the active topology? (Choose two.)


A.       root

B.       designated

C.       alternate

D.       backup

E.        forwarding

F.        learning


Correct Answer: AB




Which two statements correctly describe characteristics of the PortFast feature? (Choose two.)


A.       STP is disabled on the port.

B.       PortFast can also be configured on trunk ports.

C.       PortFast is needed to enable port-based BPDU guard.

D.       PortFast is used for STP and RSTP host ports.

E.        PortFast is used for STP-only host ports.


Correct Answer: BD




Which statement correctly describes the Cisco implementation of RSTP?


A.       PortFast, UplinkFast, and BackboneFast specific configurations are ignored in Rapid PVST


B.       RSTP is enabled globally and uses existing STP configuration.

C.       Root and alternative ports transition immediately to the forwarding state.

D.       Convergence is improved by using subsecond timers for the blocking, listening, learning, and

forwarding port states.


Correct Answer: B




What is the effect of applying the switchport trunk encapsulation dot1q command to a port on a Cisco Catalyst switch?


A.       By default, native VLAN packets going out this port are tagged.

B.       Without an encapsulation command, 802.1Q is the default encapsulation if DTP fails to

negotiate a trunking protocol.

C.       The interface supports the reception of tagged and untagged traffic.

D.      If the device connected to this port is not 802.1Q-enabled, it is unable to handle 802.1Q



Correct Answer: C




You are the administrator of a switch and currently all host-connected ports are configured with the portfast command. You have received a new directive from your manager that states that, in the future, any host- connected port that receives a BPDU should automatically disable PortFast and begin transmitting BPDUs. Which command will support this new requirement?


A.       Switch(config)#spanning-tree portfast bpduguard default

B.       Switch(config-if)#spanning-tree bpduguard enable

C.       Switch(config-if)#spanning-tree bpdufilter enable

D.       Switch(config)#spanning-tree portfast bpdufilter default


Correct Answer: D




A port in a redundant topology is currently in the blocking state and is not receiving BPDUs. To ensure that this port does not erroneously transition to the forwarding state, which command should be configured?


A.       Switch(config)#spanning-tree loopguard default

B.       Switch(config-if)#spanning-tree bdpufilter

C.       Switch(config)#udld aggressive

D.       Switch(config-if)#spanning-tree bpduguard


Correct Answer: A




Which command can be issued without interfering with the operation of loop guard?


A.       Switch(config-if)#spanning-tree guard root

B.       Switch(config-if)#spanning-tree portfast

C.       Switch(config-if)#switchport mode trunk

D.       Switch(config-if)#switchport mode access


Correct Answer: C




Which statement is a characteristic of multi-VLAN access ports?


A.       The port has to support STP PortFast.

B.       The auxiliary VLAN is for data service and is identified by the PVID.

C.       The port hardware is set as an 802.1Q trunk.

D.      The voice service and data service use the same trust boundary.


Correct Answer: C




Which two statements are true about recommended practices that are to be used in a local VLAN solution design where layer 2 traffic is to be kept to a minimum? (Choose two.)


A.        Routing should occur at the access layer if voice VLANs are utilized. Otherwise, routing

should occur at the distribution layer.

B.        Routing may be performed at all layers but is most commonly done at the core and

distribution layers.

C.        Routing should not be performed between VLANs located on separate switches.

D.        VLANs should be local to a switch.

E.         VLANs should be localized to a single switch unless voice VLANs are being utilized.


Correct Answer: BD
