A full-tunnel VPN routes all of a user's network traffic through the corporate network. This means that the organization can inspect all network traffic for security and compliance purposes, as all data is tunneled through the VPN, allowing for comprehensive monitoring and inspection.

802.1Q tagging, also known as VLAN tagging, is used to identify VLANs on a trunk link between switches.
This allows the switches to transfer data for multiple VLANs (or networks) over a single physical connection.
This method ensures that traffic from different VLANs is properly separated and managed across the network.References:CompTIA Network+ study materials.

802.1x is a network access control protocol that provides an authentication mechanism to devices trying to connect to a LAN or WLAN. This ensures that only authorized devices can access the network, making it ideal for mitigating the risk of unknown devices connecting to the network, especially in accessible areas.
802.1x Authentication: Requires devices to authenticate using credentials (e.g., username and password, certificates) before gaining network access.
Access Control: Prevents unauthorized devices from connecting to the network, enhancing security in public or semi-public areas.
Implementation: Typically used in conjunction with a RADIUS server to manage authentication requests.

* Definition of SD-WAN:
* Software-Defined Wide Area Network (SD-WAN) is a technology that simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. It allows for centralized management and enhanced security.
* Benefits of SD-WAN:
* Reduced Provisioning Time: SD-WAN enables quick and easy deployment of new sites with centralized control and automation.
* Security: Incorporates advanced security features such as encryption, secure tunneling, and
* integrated firewalls.
* Scalability: Easily scales to accommodate additional sites and bandwidth requirements.
* Comparison with Other Technologies:
* VXLAN (Virtual Extensible LAN): Primarily used for network virtualization within data centers.
* VPN (Virtual Private Network): Provides secure connections but does not offer the centralized management and provisioning efficiency of SD-WAN.
* NFV (Network Functions Virtualization): Virtualizes network services but does not specifically address WAN management and provisioning.
* Implementation:
* SD-WAN solutions are implemented by deploying edge devices at each site and connecting them to a central controller. This allows for dynamic routing, traffic management, and security policy enforcement.
