  A. switch(config)#spanning-tree portfast default

  B. switch(config)#spanning-tree portfast bpduguard default

  C. switch(config-if)#spanning-tree portfast trunk

  D. switch(config-if)#no spanning-tree portfast

  Correct Answer: A

  int g0/2 spanning-tree portfast.

  You can also enable portfast with the following command:

  SW1(config)# spanning-tree portfast default

  (this enables portfast on all access ports (not trunk ports).

• Question 615:

  Refer to Exhibit. Which configuration must be applied to the router that configures PAT to translate all addresses in VLAN 200 while allowing devices on VLAN 100 to use their own IP addresses?

  

  A. Router1(config)#access-list 99 permit 192.168.100.32 0.0.0.31 Router1(config)#ip nat inside source list 99 interface gi1/0/0 overload Router1(config)#interface gi2/0/1.200 Router1(config)#ip nat inside Router1(config)#interface gi1/0/0 Router1(config)#ip nat outside

  B. Router1(config)#access-list 99 permit 192.168.100.0 0.0.0.255 Router1(config)#ip nat inside source list 99 interface gi1/0/0 overload Router1(config)#interface gi2/0/1.200 Router1(config)#ip nat inside Router1(config)#interface gi1/0/0 Router1(config)#ip nat outside

  C. Router1(config)#access-list 99 permit 209.165.201.2 255.255.255.255 Router1(config)#ip nat inside source list 99 interface gi1/0/0 overload Router1(config)#interface gi2/0/1.200 Router1(config)#ip nat inside Router1(config)#interface gi1/0/0 Router1(config)#ip nat outside

  D. Router1(config)#access-list 99 permit 209.165.201.2 0.0.0.0 Router1(config)#ip nat inside source list 99 interface gi1/0/0 overload Router1(config)#interface gi2/0/1.200 Router1(config)#ip nat inside Router1(config)#interface gi1/0/0 Router1(config)#ip nat outside

  Correct Answer: A

• Question 616:

  Refer to the exhibit. Which switch becomes the root of the spanning tree for VLAN 110?

  

  A. Switch 1

  B. Switch 2

  C. Switch 3

  D. Switch 4

  Correct Answer: B

  The root bridge is the bridge with the lowest Bridge ID. All the decisions like which ports are the root ports (the port with the best path to the root bridge) are made from the perspective of the root bridge. In case of a tie (not the case in this example) then the root bridge will be the switch with the lowest MAC address.

• Question 617:

  Refer to the exhibit.

  B. interface gigabitethernet1/1 switchport mode access switchport access vlan 8 ! interface gigabitethernet1/3 switchport mode trunk switchport trunk vlan 8 switchport voice vlan 9

  C. interface gigabitethernet1/1 switchport mode access switchport access vlan 9 ! interface gigabitethernet1/3 switchport mode trunk switchport trunk vlan 8 switchport trunk vlan 9

  D. interface gigabitethernet1/1 switchport mode access switchport access vlan 8 ! interface gigabitethernet1/3 switchport mode access switchport voice vlan 8
