Question 1

Question
Which statement is true about RSTP topology changes?
Answer
  • Any change in the state of the port generates a TC BPDU.
  • Only non-edge ports moving to the forwarding state generate a TC BPDU.
  • If either an edge port or a non-edge port moves to a block state, then a TC BPDU is generated.
  • Only edge ports moving to the blocking state generate a TC BPDU.

Question 2

Question
Why are users from VLAN 100 unable to ping users on VLAN 200?
Answer
  • Encapsulation on the switch is wrong.
  • Trunking must be enabled on Fa0/1.
  • The native VLAN is wrong.
  • VLAN 1 needs the no shutdown command.
  • IP routing must be enabled on the switch.

Question 3

Question
The link between switch SW1 and switch SW2 is configured as a trunk, but the trunk failed to establish connectivity between the switches. Based on the configurations and the error messages received on the console of SW1, what is the cause of the problem?
Answer
  • The two ends of the trunk have different duplex settings.
  • The two ends of the trunk have different EtherChannel configurations.
  • The two ends of the trunk have different native VLAN configurations
  • The two ends of the trunk allow different VLANs on the trunk.

Question 4

Question
When you create a network implementation for a VLAN solution, what is one procedure that you should include in your plan?
Answer
  • Perform an incremental implementation of components.
  • Implement the entire solution and then test end-to-end to make sure that it is performing as designed.
  • Implement trunking of all VLANs to ensure that traffic is crossing the network as needed before performing any pruning of VLANs.
  • Test the solution on the production network in off hours.

Question 5

Question
You have just created a new VLAN on your network. What is one step that you should include in your VLAN-based implementation and verification plan?
Answer
  • Verify that different native VLANs exist between two switches for security purposes.
  • Verify that the VLAN was added on all switches with the use of the show vlan command.
  • Verify that the switch is configured to allow for trunking on the switch ports.
  • Verify that each switch port has the correct IP address space assigned to it for the new VLAN.

Question 6

Question
Which two statements describe a routed switch port on a multilayer switch? (Choose two.)
Answer
  • Layer 2 switching and Layer 3 routing are mutually supported.
  • The port is not associated with any VLAN.
  • The routed switch port supports VLAN subinterfaces.
  • The routed switch port is used when a switch has only one port per VLAN or subnet.
  • The routed switch port ensures that STP remains in the forwarding state.

Question 7

Question
On a multilayer Cisco Catalyst switch, which interface command is used to convert a Layer 3 interface to a Layer 2 interface?
Answer
  • switchport
  • no switchport
  • switchport mode access
  • switchport access vlan vlan-id

Question 8

Question
All network links are FastEthernet. Although there is complete connectivity throughout the network, Front Line users report that they experience slower network performance when accessing the server farm than the Reception office experiences. Which two statements are true? (Choose two.)
Answer
  • Changing the bridge priority of S1 to 4096 would improve network performance.
  • Changing the bridge priority of S1 to 36864 would improve network performance.
  • Changing the bridge priority of S2 to 36864 would improve network performance.
  • Changing the bridge priority of S3 to 4096 would improve network performance.
  • Disabling the Spanning Tree Protocol would improve network performance.
  • Upgrading the link between S2 and S3 to Gigabit Ethernet would improve performance.

Question 9

Question
What does the command channel-group 1 mode desirable do?
Answer
  • enables LACP unconditionally
  • enables PAgP only if a PAgP device is detected
  • enables PAgP unconditionally
  • enables EtherChannel only
  • enables LACP only if an LACP device is detected

Question 10

Question
Which two statements are true? (Choose two.)
Answer
  • Interface gigabitethernet 0/1 has been configured as Layer 3 ports.
  • Interface gigabitethernet 0/1 does not appear in the show vlan output because switchport is enabled.
  • Interface gigabitethernet 0/1 does not appear in the show vlan output because it is configured as a trunk interface.
  • VLAN2 has been configured as the native VLAN for the 802.1q trunk on interface gigabitethernet 0/1.
  • Traffic on VLAN 1 that is sent out gigabitethernet 0/1 will have an 802.1q header applied.
  • Traffic on VLAN 2 that is sent out gigabitethernet 0/1 will have an 802.1q header applied
