Answer: C
Explanation:
VTP revision number is to indicate the modified version that VTP configured is a 32-bit value,
which begins with 0. If VLAN information changes, the revision number will plus 1 until
4294967295. Then circulate and then return 0, re-start and increase.
When the monitoring switch receives notices bigger than the revision number they stored, this
notice will override the stored VLAN information, and thus it is very important to set the added
revision number of the switch to default 0.
To set the revision number to default 0, the following methods may be useD.
1> change the mode of switch VTP to transparent mode, and then return to the server mode
2> make changes to switch VTP domain name, and revert to the original domain name
