F. A switch in the VTP server mode will update switches in the VTP client mode regardless of the configured VTP

Answer: A,B,D
Explanation:
VTP operates in one of three modes: Server - In this VTP mode you can create, remove, and modify VLANs. You
can also set other configuration options like the VTP version and also turn on/off VTP pruning for the entire VTP
domain. VTP servers advertise their VLAN configuration to other switches in the same VTP domain and
synchronize their VLAN configuration with other switches based on messages received over trunk links. VTP
server is the default mode. The VLANs information are stored on NVRAM and they are not lost after a reboot.
Client - VTP clients behave the same way as VTP servers, but you cannot create, change, or delete VLANs on the
local device. In VTP client mode, VLAN configurations are not saved in NVRAM.
