Question

Which protocol reduces administrative overhead in a switched network by allowing the configuration of a new VLAN to be distributed to all the switches in a domain?
1. STP
2. VTP
3. DHCP
4. ISL

Answer 1

Correct Answer - Option 2 : VTP

VTP:

• VTP stands for Virtual Trunk Protocol
• It is used to pass VLAN database to all switches in the switched network domain.

 

There are three VTP modes

1. Server
2. Client
3. Transparent

 

DHCP:

• DHCP stands for Dynamic host configuration protocol
• It provides IP address dynamically.

 

ISL:

• ISL stands for Inter switch link (Cisco specific implementation)
• It is used for trunking multiple VLANs between Cisco switches where a single interface will carry traffic for more than one VLAN

 

STP:

• STP stands for Spanning Tree Protocol
• It uses the spanning tree algorithm to create a topology database of the network.

 

Hence option 2 is the correct answer.
