When the user moves to another location, the switch port is assigned to a different VLAN for that user When the user moves to another location, the switch port is assigned to the same VLAN for that user Dynamic VLAN assignment allows for de-centralized network management Dynamic VLAN assignment allows for centralized network management Question 5 of 23 6. Which of the following statements are TRUE in regards to VLANs? A VLAN is a logical grouping of hosts that appear to be on the same LAN, regardless of their physical location VLANs increase the number of Broadcast domains, but reduce their overall size VLANs decrease the number of Broadcast domains, but increase their overall size A VLAN is a physical grouping of hosts that appear to be on the same LAN, regardless of their logical location Question 6 of 23 7. Which of the following is TRUE in regards to dynamic VLAN assignment with VMPS? The dynamic assignement is based on the IP address of the host The dynamic assignment is based on the MAC address of the switch port The dynamic assignment is based on the MAC address of the host The dynamic assignment is based on the port-based VLAN membership Question 7 of 23 8. What is used to increase the efficiency of trunk links by eliminating unnecessary Broadcast, Multicast and unknown traffic from being propagated across the network? VTP Pruning ISL VTP Transparent mode Port Filtering DISL 802.1Q Question 8 of 23 9. Which of the following DTP modes will NOT result in the establishment of a trunk? auto – auto desirable – desirable desirable – auto auto – desirable Question 9 of 23 10. What does the switch use to create the BID when the extended system ID or MAC address reduction feature is enabled? Different MAC addresses The Switch Priority The internal VLAN A single MAC address The VLAN ID Question 10 of 23 11. What is TRUE in regards to the origins of the native VLAN when using the 802.1Q standard? The IEEE defined the native VLAN to prevent special frames from being tagged The IEEE defined the native VLAN to allow ISL and 802.1Q compatibility The IEEE defined the native VLAN to provide for connectivity to old 802.3 ports that did not understand VLAN tags The IEEE defined the native VLAN to carry specific protocol traffic like Cisco Discovery Protocol (CDP) Question 11 of 23 12. The following command is used on a port being configured as a trunk port: switchport trunk encapsulation negotiate What is TRUE in regards to this configuration? It means that if DISL and DTP negotiation fails to successfully agree on the encapsulation format, then the trunk will not be established It means that if DISL and DTP negotiation fails to successfully agree on the encapsulation format, then 802.1Q is the selected format It means that if DISL and DTP negotiation fails to successfully agree on the encapsulation format, the Catalyst switch will generate an error message asking for administrator intervention It means that if DISL and DTP negotiation fails to successfully agree on the encapsulation format, then ISL is the selected format Question 12 of 23 13. What information does VTP advertise to other switches? The VLAN Maximum Transmission Unity (MTU) VTP Mode The VTP Configuration Mode Management domain Configuration Revision Number Question 13 of 23 14. Which of the following statements are TRUE in regards to VTP Pruning? VLAN 1 and VLANs 1002 to 1005 are always pruning-ineligible VTP pruning must be enabled on all switches in the VTP domain Enabling VTP pruning on the server enables it for the entire VTP domain VLAN 1 and VLANs 1002 to 1006 are always pruning-ineligible It is disabled by default It is enabled by default on all VTP servers Question 14 of 23 15. Which of the following statements are FALSE in regards to ISL and 802.1Q? With 802.1Q, the trunking device does not recalculate the FCS before it sends the frame over the trunk link When an ISL header is attached, the original FCS is added to the end of the frame When an ISL header is attached, a new FCS is calculated over the entire ISL packet and added to the end of the frame With 802.1Q, the trunking device must recalculate the FCS before it sends the frame over the trunk link Question 15 of 23 16. Your co-worker B. Wildered is about to implement a new VTP Client switch into the existing VTP domain. You advise him to reset the Configuration Revision Number before integrating the switch into the network. He has no idea on how this can be performed. Which of the following would you tell him? Change the switch to Transparent mode and then change it back Change the VTP domain name and then change it back Use the config-rev 0 global configuration command to set the Configuration Revison Number to 0 Simply reboot the switch Question 16 of 23 17. In what two ways can VLANs be implemented? As dynamic VLANs As end-to-end VLANs As static VLANs As local VLANs Question 17 of 23 18. What Cisco proprietary Layer 2 messaging protocol manages the addition, deletion, and renaming of VLANs on switches in the same VTP domain? ISL PVST VTP CDP Question 18 of 23 19. Click on the Exhibit. What command is required to add VLAN 80 to the list of allowed VLANs on the trunk? switchport trunk allowed vlan none except 80 switchport trunk allowed vlan remove all except 80 switchport trunk allowed vlan add 80 switchport trunk allowed vlan 80 switchport trunk add vlan 80 switchport trunk add vlan 80 Question 19 of 23 20. What is TRUE in regards to suspending and shutting down VLANs? Suspending the VLAN is used to prevent packets from being forwarded in a VLAN on the local switch without affecting the forwarding of packets for all other hosts in that VLAN throughout the entire switched LAN Shutting down the VLAN is used to prevent packets from being forwarded in a VLAN on the local switch without affecting the forwarding of packets for all other hosts in that VLAN throughout the entire switched LAN Suspending the VLAN retains the configuration, such as all access ports assigned to the VLAN, but prevents the VLAN from passing traffic until it is manually transitioned to an active state Shutting down the VLAN retains the configuration, such as all access ports assigned to the VLAN, but prevents the VLAN from passing traffic until it is manually transitioned to an active state Question 20 of 23 21. Which of the following is TRUE in regards to VTP? There is no restriction on the number of VTP server switches that can exist within the VTP domain Only two VTP servers, the Root and Backup Root Bridge, can exist within the VTP domain In VTP version 2, transparent mode switches do not relay received VTP information to other switches unless the VTP domain names and VTP version numbers match those of the other switches VTP clients cannot modify VLANs but do store the VTP database in NVRAM In VTP version 1, transparent mode switches do not relay received VTP information to other switches unless the VTP domain names and VTP version numbers match those of the other switches Question 21 of 23 22. What methods can be used to configure the switch with a VTP domain name? manual configuration CDP automatic assignment Dynamic ISL domain assignment dynamic domain assignment Question 22 of 23 23. Which of the following statements are FALSE about internal VLANs in Catalyst 6500 series switches? The show internal vlan usage command is used to view internal VLAN allocation The show vlan internal usage command is used to view internal VLAN allocation Layer 2 Ethernet ports consume one extended VLAN number By default, internal VLANs are allocated in descending order Layer 3 Ethernet ports consume one extended VLAN number By default, internal VLANs are allocated in ascending order Question 23 of 23 Loading…
