An MNC hired Brandon, a network defender, to establish secured VPN communication between the company's remote offices. For this purpose, Brandon employed a VPN topology where all the remote offices communicate with the corporate office but communication between the remote offices is denied. Identify the VPN topology employed by Brandon in the above scenario.

In a Hub-and-Spoke VPN topology, multiple remote networks (spokes) securely connect to a central corporate network (hub). The spokes cannot communicate directly with one another; all traffic must pass through or is restricted by the central hub. This topology is highly scalable and allows centralized security policy enforcement, making it ideal for organizations with a main headquarters and multiple branch offices that require secure access to central resources without needing direct branch-to-branch communication.

A. Point-to-Point VPN topology connects exactly two endpoints directly, rather than connecting multiple remote offices to a central hub.
B. Star topology is a general physical or logical LAN networking term, whereas Hub-and-Spoke is the specific architectural terminology used for this VPN deployment.
D. Full-mesh VPN topology allows every remote office to communicate directly with every other remote office, which directly contradicts the scenario's restrictions.
