Testking : VTP Trunk

[best1980]

Ciao a tutti... sto studiando un po' sui testking e non ho capito una domanda in particolare:

A New switch is installaed into an existing LAN and a new VTP trunk is set up with an existing switch. Which VLANs will be allowed on this new trunk?

A. All defined VLANs are allowed on the trunk by default.
B. Each VLAN, or VLAN range, that is specified with the switchport mode command.
C. Each VLAN, or VLAN range, that is specified with the vtp domain command.
D. Each VLAN, or VLAN range, that is specified with the vlan database command.

Answer: C
Explanation:
By default, all VLANs that are configured to be in the same VTP domain will be allowed
by the VTP trunk.

Più avanti invece c'è questa domanda:

When a new trunk link is configured on an IOS based switch, which VLANs are
allowed over the link?
A. By default, all defined VLANs are allowed on the trunk.
B. Each single VLAN, or VLAN range, must be specified with the switchport mode
command.
C. Each single VLAN, or VLAN range, must be specified with the vtp domain command.
D. Each single VLAN, or VLAN range, must be specified with the vlan database
command.

Answer: A
Explanation:
By default, all VLANs are allowed over a trunk at all times. This is true for every Cisco
IOS switch that is capable of VLAN trunking.

Come vedete le risposte sono diverse anche se le domande sembrano le stesse...

dove sbaglio?

Quale è quella corretta?

Ciao e grazie in anticipo
