AEF.

VLAN Trunking Protocol version 3 (VTPv3) is a protocol used to synchronize VLAN information between Cisco switches. Below are the explanations for each statement:

A. It supports 4K VLANs: VTPv3 supports up to 4K VLANs, which is an increase from the 1K VLANs supported by VTPv1 and VTPv2.

B. It supports manual configuration of VLANs on a device configured as a VLAN Trunking Protocol client: Unlike VTPv1 and VTPv2, VTPv3 allows manual configuration of VLANs on a device configured as a VTP client. This means that even if the switch is not in VTP server mode, it can still have VLANs configured on it.

C. It does not support private VLANs: VTPv3 does not support private VLANs, which are used to isolate ports on a switch from each other.

D. It is not compatible with VLAN Trunking Protocol version 1 or 2: VTPv3 is not backward compatible with VTPv1 or VTPv2. This means that if you upgrade to VTPv3, switches running VTPv1 or VTPv2 will not be able to synchronize VLAN information with the VTPv3 switches.

E. It allows only the primary server to make VLAN Trunking Protocol configuration changes: In VTPv3, only the primary server can make configuration changes to the VLAN database. This is to prevent accidental or malicious changes to the VLAN database.

F. It provides enhanced security with hidden and secret passwords: VTPv3 provides enhanced security by supporting hidden and secret passwords. Hidden passwords are encrypted, and secret passwords are hashed, making them more secure than plain-text passwords.

In summary, VTPv3 supports up to 4K VLANs, allows manual configuration of VLANs on VTP clients, does not support private VLANs, is not compatible with VTPv1 or VTPv2, allows only the primary server to make configuration changes, and provides enhanced security with hidden and secret passwords.
