  D. 8-bytes including native VLAN
  A. 4-bytes except the native VLAN

  ---

  In 802.1Q trunking, all VLAN packets are tagged on the trunk link, except the native VLAN. A VLAN tag adds 4 bytes to the frame. Two bytes are used for the tag protocol identifier (TPID), the other two bytes for tag control information (TCI).

  A. username and password
  B. entire payload
  C. entire header
  D. password
  A. username and password

• Question 843:

  Refer to the exhibit.

  

  All switches are configured with the default port priority value. Which two commands ensure that traffic from PC1 is forwarded over the Gi1/3 trunk port between DSW1 and DSW2? (Choose two.)

  A. DSW1(config-if)# spanning-tree port-priority 0
  B. DSW2(config)# interface gi1/3
  C. DSW2(config-if)# spanning-tree port-priority 128
  D. DSW1(config-if)# spanning-tree port-priority 16
  E. DSW2(config-if)# spanning-tree port-priority 16
  F. DSW1(config)# interface gi1/3
  B. DSW2(config)# interface gi1/3
  C. DSW2(config-if)# spanning-tree port-priority 128

• Question 844:

  Missing the exhibit.

  Based on the output,which two statements are true?(choose two)

  A. the device sends unicast messages to its peers
  B. the standby device is configured with the default HSRP priority
  C. the device is using the default HSRP hello timer
  D. the device is configured with the default HSRP priority
  E. the device is HSRP group uses the virtual IP address 10.10.2.242
  B. the standby device is configured with the default HSRP priority
  C. the device is using the default HSRP hello timer

• Question 845:

  A question about isolated port private VLAN.

  A. It can communicate only on isolated port.
  B. It can configure more than one on the same port VLAN.
  C. www.certbus.com
  D. www.certbus.com
  A. It can communicate only on isolated port.

• Question 846:

  Which command globally enables AAA on a device?

  A. aaa new-model
  B. aaa authentication
  C. aaa authorization
  D. aaa accounting
  A. aaa new-model

  ---

  To configure AAA authentication, enable AAA by using the aaa new-model global configuration command.

  AAA features are not available for use until you enable

  AAA globally by issuing the aaa new-model command.

• Question 847:

  HSRP Ferris Plastics, Inc. is a medium sized company, with an enterprise network (access, distribution and core switches) that provides LAN connectivity from user PCs to corporate servers. The distribution switches are configured to use HSRPto provide a high availability solution.

  -DSW1 -primary device for VLAN 101 VLAN 102 andVLAN 105

  -DSW2 - primary device for VLAN 103 and VLAN 104

  - A failure of GigabitEthemet1/0/1 on primary device should cause the primary device to release its status as the primary device, unless GigabitEthernet1/0/1 on backup device has also failed. Troubleshooting has identified several issues. Currently all interfaces are up. Using the running configurations and show commands, you have been asked to investigate and respond to the following question.

  

  All interfaces are active. DSW2 has not become the active device for the VLAN 103 HSRP group. As related to the VLAN 103 HSRP group, what can be done to make the group function properly?

  A. On DSW1, disable preempt.
  B. On DSW1, decrease the priority value to a value less than 190 and greater than 150.
  C. On DSW2, increase the priority value to a value greater 200 and less than 250.
  D. On DSW2, increase the decrement value in the track command to a value greater than 10 and less than 50.
  C. On DSW2, increase the priority value to a value greater 200 and less than 250.

  ---

  From the output shown below of the HSRP status of DSW2, we see that the active router has a priority of 200, while the local priority is 190. We need to increase the priority of DSW2 to greater than 200, but it should be less than 250 so that if the gig 1/0/1 interface goes down, DSW1 will become active. DSW2 is configured to decrement the priority by 50 if this interface goes down, so the correct answer is to increase the priority to more than 200, but less than 250.

  

• Question 848:

  Which information does the subordinate switch in a switch stack keep for all the VLANs that are configured on it?

  A. VLAN database
  B. DHCP snooping database
  C. spanning trees
  D. routing information
  C. spanning trees

• Question 849:

  Which statement about restrictions for multichassis LACP is true?

  A. It is available only on a Cisco Catalyst 6500 Series chassis.
  B. It does not support 1Gb links.
  C. Converting a port channel to mLACP can cause a service disruption.
  D. It is not available in VSS.
  C. Converting a port channel to mLACP can cause a service disruption.

  ---

  When configuring mLACP for Server Access, follow these guidelines and restrictions:

  PFC3A mode does not support the mLACP for server access feature.

  VSS mode does not support the mLACP for server access feature.

  No more than 100 VLANs can be active on a switch configured as a PoA.

  mLACP does not support half-duplex links.

  mLACP does not support multiple neighbors.

  Converting a port channel to mLACP can cause a service disruption.

  The DHD system priority must be lower (higher numerically) than the PoA system priority.

• Question 850:

  A physical switch port is part of an EtherChannel group. What happens while the same port is configured as a SPAN destination?

  A. The port is removed from the EtherChannel group.
  B. The operation is not allowed as an EtherChannel member cannot be a SPAN source port.
  C. The port forwards traffic in the EtherChannel group and acts as a SPAN source simultaneously.
  D. The port is put in the errdisabled state and can only be re-enabled manually.
  A. The port is removed from the EtherChannel group.
