You must add a new switch to the existing network using VTP to maintain the VLAN databases.
Which mode should be configured on this switch so that VLANs can be separately maintained on this switch?
A. None
B. Client
C. Server
D. Transparent
Correct Answer: D
Explanation/Reference:
Answer:
Adding a switch configured in VTP transparent mode allows the administrator to maintain the switch VLAN configuration information and not advertise its database to other switches in the network.
A VTP transparent mode switch will receive and forward VTP advertisements. The VTP transparent mode switch will not use the contents of the advertisement to synchronize with its own VLAN database.
VTP advertisements are flooded throughout the management domain every five minutes or whenever there is a change. These advertisements originate from a switch that is in server mode and are propagated by switches that are in either client or transparent mode. Before a client or another server accepts or incorporates the information sent in the advertisement, it checks the domain name and password (if defined) against its own configuration. Next, the revision number is checked to see if it is higher than the last value stored in the receiving switch. If the revision number is higher, the receiving switch will overwrite its VLAN database with the information in the advertisement.
The VTP server mode sends or forwards VTP advertisements, synchronizes VLAN configuration information with other switches, and saves the VLAN in NVRAM.
The VTP client mode sends or forwards VTP advertisements and synchronizes VLAN configuration information with other switches. It does not save VLAN information in NVRAM. In client mode, VTP clients only can receive VLAN information from VTP servers.
