Chapter 1 – Implement VLAN based solution, given a network design and a set of requirements
QUESTION NO: 26
Switch R1 and R2 both belong to the Company VTP domain. What’s true about the switch operation in VTP domains? (Select all that apply)
A. A switch can only reside in one management domain
B. A switch is listening to VTP advertisements from their own domain only
C. A switch is listening to VTP advertisements from multi domains
D. A switch can reside in one or more domains
E. VTP is no longer supported on Catalyst switches
A VTP domain is made up of one or more interconnected devices that share the same VTP domain name. A switch can be configured to be in only one VTP domain, and each VLAN has a name that is unique within a management domain. Typically, you use a VTP domain to ease administrative control of your network or to account for physical boundaries within your network. However, you can set up as many or as few VTP domains as are appropriate for your administrative needs. Consider that VTP is transmitted on all trunk connections, including ISL, IEEE 802.1Q, 802.10, and LANE. Switches can only belong to one management domain with common VLAN requirements, and they only care about the neighbors in their own domains.
QUESTION NO: 27
VTP devices in a network track the VTP revision number. What is a VTP configuration revision number?
A. A number for identifying changes to the network switch.
B. A number for identifying changes to the network router.
C. A number for identifying changes to the network topology.
D. None of the other alternatives apply.
The configuration revision number is a 32-bit number that indicates the level of revision for a VTP packet. Each VTP device tracks the VTP configuration revision number assigned to it, and most of the VTP packets contain the VTP configuration revision number of the sender. This information is used to determine whether the received information is more recent than the current version. Each time you make a VLAN change in a VTP device, the configuration revision is incremented by one. In order to reset the configuration revision of a switch, change the VTP domain name and then change it back to the original name.
QUESTION NO: 28
Switch R1 is configured to use the VLAN Trunking Protocol (VTP). What does R1 advertise in its VTP domain?
A. The VLAN ID of all known VLANs, the management domain name, and the total number of trunk links on the switch.
B. The VLAN ID of all known VLANs, a 1-bit canonical format (CF1 Indicator), and the switch configuration revision number.
C. The management domain name, the switch configuration revision number, the known VLANs, and their specific parameters.
D. A 2-byte TPID with a fixed value of 0x8100 for the management domain number, the switch configuration revision number, the known VLANs, and their specific parameters.
E. None of the other alternatives apply.
“Each switch participating in VTP advertises VLAN information, revision numbers, and VLAN parameters on its trunk ports to notify other switches in the management domain. VTP advertisements are sent as multicast frames. The switch intercepts frames sent to the VTP multicast address and processes them with its supervisory processor VTP frames are forwarded out trunk links as a special case. The following global configuration information is distributed in VTP advertisements:
QUESTION NO: 29
VTP switches use advertisements to exchange information with each other. Which of the following advertisement types are associated with VTP? (Select all that apply)
A. Domain advertisements
B. Advertisement requests from clients
C. Subset advertisements
D. Summary advertisements
QUESTION NO: 30
Switch R1 is part of the Company VTP domain. What’s true of VTP Pruning within this domain? (Select all that apply)
A. It does not prune traffic from VLANs that are pruning-ineligible
B. VLAN 1 is always pruning-eligible
C. it will prune traffic from VLANs that are pruning-ineligible
D. VLAN 2 is always pruning-ineligible
E. None of the other alternatives apply.
By definition, pruning-ineligible VLANs can not be pruned. You can make specific VLANs pruning ineligible with the clear vtp pruneeligible vlan_range command. By default, VLANs 2-1000 are pruning-eligible. Since the default VLAN for any switch port in a Catalyst switch is VLAN 1, it is not eligible for pruning.
