Which VPN technology allows remote locations to appear as a single LAN segment?

A. B. C. D.A
VPLS is a virtual private network (VPN) technology. A VPLS is a provider service that emulates the full functionality of a traditional Local area network (LAN). A
VPLS makes it possible to interconnect several LAN segments over a packet switched network (PSN) and makes the remote LAN segments behave as one single
LAN.

The correct answer is A. VPLS (Virtual Private LAN Service).
VPLS is a Layer 2 VPN technology that enables multiple remote locations to appear as if they are on the same LAN segment, allowing for seamless communication between them. With VPLS, each remote site is connected to the same virtual bridge, which extends the LAN to include all the sites.
VPLS is often used in enterprise networks to connect geographically dispersed sites and provide a consistent and transparent network experience for end-users. It can also be used by service providers to offer VPN services to their customers.
Other options listed are:
B. CCC (Cisco Compatible Client) - This is not a VPN technology, but rather a client software used to connect to a Cisco VPN Concentrator.
C. Layer 3 VPN - This is a VPN technology that uses Layer 3 (network layer) routing protocols to provide secure communication between remote sites. Unlike VPLS, it does not make the remote sites appear as a single LAN segment.
D. L2TP (Layer 2 Tunneling Protocol) - This is a VPN protocol that provides secure communication between remote sites by encapsulating data in a tunnel over the Internet. However, like Layer 3 VPN, it does not make the remote sites appear as a single LAN segment.
