• Question 211:

  Which statement describes what happens when a switch enters dual active recovery mode?

  A. The switch shuts down and waits for the VSL link to be restored before sending traffic.
  B. All interfaces are shut down in the formerly active virtual switch member, but the new active virtual switch forwards traffic on all links.
  C. The switch continues to forward traffic out all links and enables spanning tree on VSL link and all other links to prevent loops.
  D. The VSS detects which system was last in active state and shuts down the other switch.
  B. All interfaces are shut down in the formerly active virtual switch member, but the new active virtual switch forwards traffic on all links.

  ---

  In the dual active recovery mode, all interfaces except the VSL interfaces are in an operationally shut down state in the formerly active virtual switch member. The new active virtual switch continues to forward traffic on all links.

• Question 212:

  Refer to the exhibit.

  

  Which set of configurations will result in all ports on both switches successfully bundling into an EtherChannel?

  A. switch1 channel-group 1 mode active switch2 channel-group 1 mode auto
  B. switch1 channel-group 1 mode desirable switch2 channel-group 1 mode passive
  C. switch1 channel-group 1 mode on switch2 channel-group 1 mode auto
  D. switch1 channel-group 1 mode desirable switch2 channel-group 1 mode auto
  D. switch1 channel-group 1 mode desirable switch2 channel-group 1 mode auto

  ---

  The different etherchannel modes are described in the table below:

  Mode Description

  active Places an interface into an active negotiating state, in which the interface starts negotiations with other interfaces by sending LACP packets. auto Places an interface into a passive negotiating state, in which the interface re- sponds to

  PAgP packets it receives but does not start PAgP packet negotia- tion.

  This setting minimizes the transmission of PAgP packets.

  desirable Places an interface into an active negotiating state, in which the interface starts negotiations with other interfaces by sending PAgP packets.

  on Forces the interface into an EtherChannel without PAgP or LACP. With the on mode, a usable EtherChannel exists only when an interface group in the on mode is connected to another interface group in the on mode.

  passive Places an interface into a passive negotiating state, in which the interface re- sponds to LACP packets that it receives, but does not start LACP packet ne- gotiation. This setting minimizes the transmission of LACP packets.

  Both the auto and desirable PAgP modes allow interfaces to negotiate with partner interfaces to determine if they can form an EtherChannel based on criteria such as interface speed and, for Layer 2 EtherChannels, trunking state and VLAN

  numbers. Interfaces can form an EtherChannel when they are in different PAgP modes as long as the modes are compatible. For example:

  An interface in the desirable mode can form an EtherChannel with another interface that is in the desirable or auto mode.

  An interface in the auto mode can form an EtherChannel with another interface in the desirable mode. An interface in the auto mode cannot form an EtherChannel with another interface that is also in the auto mode because neither interface

  starts PAgP negotiation. An interface in the on mode that is added to a port channel is forced to have the same characteristics as the already existing on mode interfaces in the channel.

• Question 220:

  There are 2 SW and 2 PCs. There is a trunk with VLAN 1 and 5 allowed.

  Question is if you do "switchport trunk allowed vlan 2,3,4" on SW2, what happens. Ports towards PCs are in mode access VLAN 5

  A. The connection is lost between PCs, because you will remove VLANs 1 and 5 from trunk with this command. You should use "switchport trunk allowed vlan" to add additional VLANs into trunk
