VTP allows a single switch port to carry information to more than one VLAN. VTP allows physically redundant links while preventing switching loops. VTP simplifies switch administration by allowing switches to automatically share VLAN configuration information. VTP helps to limit configuration errors by keeping VLAN naming consistent across the VTP domain. VTP enhances security by preventing unauthorized hosts from connecting to the VTP domain. Question 5 Which three of these statements regarding 802.1Q trunking are correct?
802.3u B D Explanation The Inter-Switch Link (ISL) and 802.1Q protocols are used to establish trunk links carrying traffic for multiple VLANs.

Local updater ID is 172.16.1.111 on interface Vl1 (lowest numbered VLAN interface found) The new switch, 1ASW3, has not yet been connected to the network.
Server Mode – In VTP server mode you can create, modify and delete vlans.

C Question 3 Which statements describe two of the benefits of VLAN Trunking Protocol? When VTP is turned on, switches will automatically share its VLANs information to other switches (which are in the same domain) by VTP updates. The correct encapsulation type has not been configured. The no shutdown command has not been entered for the port. D E Explanation VLAN Trunking Protocol (VTP) is used to ensure that all switches in a given group, or VTP domain, have the same information about the VLANs that are present in that domain.
