B.Switch SW1 has been configured with the spanning-tree vlan 1 root secondary global configuration command.
C.Switch SW1 has been configured with the spanning-tree vlan 1 priority 24577 global configuration command.

A.LACP is used to connect to non-Cisco devices.
B.LACP packets are sent with the command channel-group 1 mode desirable.
C.LACP packets are sent with the command channel-group 1 mode active.
D.Standby interfaces should be configured with a higher priority.
E.Standby interfaces should be configured with a lower priority.
Refer to the exhibit.
What does the command channel-group 1 mode desirable do？ （）
A.enables LACP unconditionally
B.enables PAgP only if a PAgP device is detected
C.enables PAgP unconditionally
D.enables Etherchannel only
E.enables LACP only if a LACP device is detected
During routine maintenance， G1/0/1 on DS1 was shutdown. All other interface were up. DS2 became the active HSRP device for Vlan101 as desired. However， after G1/0/1 on DS1 was reactivated. DS1 did not become the active HSRP device as desired.
What need to be done to make the group for Vlan101 function properly ？ （）
A. Enable preempt on DS1’s Vlan101 HSRP group
B. Disable preempt on DS1’s Vlan101 HSRP group
C. Decrease DS1’s priority value for Vlan101 HSRP group to a value that is less than priority value configured on DS2’s HSRP group for Vlan101
D. Decrease the decrement in the track command for DS1’s Vlan 101 HSRP group to a value less than the value in the track command for DS2’s Vlan 101 HSRP group.
A.The designated port is the switch port on every nonroot bridge that is the chosen path to theroot bridge. There can be only one designated port on every switch. The designated portassumes the forwarding state in a stable active topology. All switches connected to a given segment listen to all BPDUs and determine the switch that will be the root switch for a particular segment.
B.The disabled port is an additional switch port on the designated switch with a redundant link to the segment for which the switch is designated. A disabled port has a higher port ID than the disabled port on the designated switch. The disabled port assumes the discarding state in astable active topology.
C.The backup port is a switch port that offers an alternate path toward the root bridge. The backup port assumes a discarding state in a stable， active topology. The backup port will be present on nondesignated switches and will make a transition to a designated port if the current designated path fails.
D.The root port is the switch port on every nonroot bridge that is the chosen path to the root bridge. There can be only one root port on every switch. The root port assumes the forwarding state in a stable active topology.
Refer to the exhibit.
Which Virtual Router Redundancy Protocol （VRRP） statement is true about the roles of the master virtual router and the backup virtual router？（）
A.Router A is the master virtual router， and Router B is the backup virtual router. When Router A fails， Router B will become the master virtual router. When Router A recovers， Router B will maintain the role of master virtual router.
B.Router A is the master virtual router， and Router B is the backup virtual router. When Router A fails， Router B will become the master virtual router. When Router A recovers， it will regain the master virtual router role.
C.Router B is the master virtual router， and Router A is the backup virtual router. When Router B fails， Router A will become the master virtual router. When Router B recovers， Router A will maintain the role of master virtual router.
D.Router B is the master virtual router， and Router A is the backup virtual router. When Router B fails， Router A will become the master virtual router. When Router B recovers， it will regain the master virtual router role.
Examine the diagram. A network administrator has recently installed the above switched network using 3550s and would like to control the selection of the root bridge.
