Explanation
Correct Answer: B. VTP (VLAN Trunking Protocol)
- VTP (VLAN Trunking Protocol):
VTP is a Cisco proprietary protocol that allows switches to share VLAN configuration information across a network. When VTP is enabled, a change to the VLAN configuration on one switch is propagated to other switches in the same VTP domain, ensuring consistent VLAN configurations across the network.
Why others are incorrect:
-
PPTP (Point-to-Point Tunneling Protocol):
PPTP is a protocol used for creating VPNs (Virtual Private Networks) and is unrelated to VLAN configuration or information sharing between switches. -
MPLS (Multiprotocol Label Switching):
MPLS is a routing technique that uses labels to direct data between nodes in a wide area network (WAN). It does not facilitate VLAN information sharing between switches. -
STP (Spanning Tree Protocol):
STP is used to prevent network loops in a Layer 2 network by managing redundant paths. While important for network stability, it does not share VLAN information between switches.
No Payment Cards Needed
