问题 What are two results of entering the VESwitch(config)# vtp mode client command on a Catalyst switch in the Ezonexam LAN? (Choose two.)
选项 A、The switch will ignore VTP summary advertisements
B、The switch will forward VTP summary advertisements
C、The switch will process VTP summary advertisements
D、The switch will originate VTP summary advertisements
E、The switch will create, modify and delete VLANs for the entire VTP domain
答案B,C
解析 Explanation :
Server mode: VTP servers have full control over VLAN creation and modification for their domains. All VTP information is advertised to other switches in the domain, while all received VTP information is synchronized with the other switches. By default, a switch is in VTP server mode. Note that each VTP domain must have at least one server so that VLANs can be created, modified, or deleted, and VLAN information can be propagated.

Client mode: VTP clients do not allow the administrator to create, change, or delete any VLANs. Instead, they listen to VTP advertisements from other switches and modify their VLAN configurations accordingly. In effect, this is a passive listening mode. Received VTP information is forwarded out trunk links to neighboring switches in the domain, so the switch also acts as a VTP relay.

Transparent mode: VTP transparent switches do not participate in VTP. While in transparent mode, a switch does not advertise its own VLAN configuration, and a switch does not synchronize its VLAN database with received advertisements. In VTP version 1, a transparent-mode switch does not even relay VTP information it receives to other switches, unless its VTP domain names and VTP version numbers match those of the other switches. In VTP version 2, transparent switches do forward received VTP advertisements out of their trunk ports, acting as VTP relays. This occurs regardless of the VTP domain name setting.
