Remote Site Configuration Technology

C.

The technology that can provide plug-and-play with zero-touch configuration for remote locations without any local technical support is "Satellite Network Virtualization."

Satellite Network Virtualization is a Cisco technology that allows the deployment of multiple switches at remote sites without the need for on-site technicians or a complex configuration process. With this technology, a single switch, called a "master switch," can control and configure multiple switches, called "satellite switches," at remote locations. The master switch is typically located in a central data center or a network operations center (NOC).

When a satellite switch is connected to the master switch, it automatically downloads its configuration and software image from the master switch. The satellite switch also sends its status and performance data back to the master switch for monitoring and troubleshooting purposes. This process requires minimal or no intervention from on-site technicians, making it a plug-and-play solution with zero-touch configuration.

Security Context, Virtual Device Context, and Secure Domain Router are all other Cisco technologies that serve different purposes and are not designed for plug-and-play with zero-touch configuration for remote locations without any local technical support.

Security Context is a feature in Cisco ASA firewall that allows multiple virtual firewalls to be created within a single physical ASA firewall. Virtual Device Context (VDC) is a feature in Cisco Nexus switches that allows a single physical switch to be partitioned into multiple logical switches. Secure Domain Router (SDR) is a technology in Cisco IOS XR software that allows multiple virtual routers to run on a single physical router.
