• Question 64:

  An EtherChannel bundle has been established between a Cisco switch and a corporate web server. The network administrator noticed that only one of the EtherChannel links is being utilized to reach the web server. What should be done on the Cisco switch to allow for better EtherChannel utilization to the corporate web server?

  A. Enable Cisco Express Forwarding to allow for more effective traffic sharing over the EtherChannel bundle.
  B. Adjust the EtherChannel load-balancing method based on destination IP addresses.
  C. Disable spanning tree on all interfaces that are participating in the EtherChannel bundle.
  D. Use link-state tracking to allow for improved load balancing of traffic upon link failure to the server.
  E. Adjust the EtherChannel load-balancing method based on source IP addresses.
  E. Adjust the EtherChannel load-balancing method based on source IP addresses.

  EtherChannel load balancing can use MAC addresses, IP addresses, or Layer 4 port numbers, and either source mode, destination mode, or both. The mode you select applies to all EtherChannels that you configure on the switch. Use the option that provides the greatest variety in your configuration. For example, if the traffic on a channel only goes to a single MAC address (which is the case in this example, since all traffic is going to the same web server), use of the destination MAC address results in the choice of the same link in the channel each time. Use of source addresses or IP addresses can result in a better load balance. Reference: http://www.cisco.com/c/en/us/support/docs/lan-switching/ etherchannel/12023- 4.html

• Question 67:

  Which statement about using EtherChannel on Cisco IOS switches is true?

  A. A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.
  B. A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.
  C. A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 16 Gbps only for Gigabit EtherChannel.
  D. A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 10 Gbps only for Gigabit EtherChannel.
  A. A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.

  ---

  Explanation: An EtherChannel consists of individual Fast Ethernet or Gigabit Ethernet links bundled into a single logical link. The EtherChannel provides full- duplex bandwidth up to 800 Mbps (Fast EtherChannel) or 8 Gbps (Gigabit EtherChannel) between your switch and another switch or host. Each EtherChannel can consist of up to eight compatibly configured Ethernet interfaces. All interfaces in each EtherChannel must be the same speed, and all must be configured as either Layer 2 or Layer 3 interfaces.

• Question 68:

  Which command creates a login authentication method named "login" that will primarily use RADIUS and fail over to the local user database?

  A. (config)# aaa authentication login default radius local
  B. (config)# aaa authentication login login radius local
  C. (config)# aaa authentication login default local radius
  D. (config)# aaa authentication login radius local
  B. (config)# aaa authentication login login radius local

  ---

  In the command "aaa authentication login login radius local" the second login is the name of the AAA method. It also lists radius first then local, so it will primarily use RADIUS for authentication and fail over to the local user database only if the RADIUS server is unreachable.

• Question 69:

  Refer to the exhibit . Which two statements about the network environment of the interface that generated (Choose two)

  

  A. The configured VRRP priority of the interface is 120
  B. The device on which the interface resides is acting as a standby router
  C. The Skew time .531 seconds
  D. The Configured VRRP Priority of the interface is 105
  E. If the priority of another router is higher than the priority of the master router, it becomes the master router
  C. The Skew time .531 seconds
  D. The Configured VRRP Priority of the interface is 105

• Question 70:

  A. The lowest extended VLAN number is 1006.
  B. The lowest extended VLAN number is 1002.
  C. Any VLAN ID can be used as an extended VLAN.
  D. They are recognized only by VTP version 3
  E. They are propagated by VTP by default
  F. They require the extended system ID to be enabled on the device.
  A. The lowest extended VLAN number is 1006.
  D. They are recognized only by VTP version 3
  F. They require the extended system ID to be enabled on the device.
