Final answer:
The VLAN designed for administrative access to networking devices is known as the management VLAN. It allows secure and remote login for monitoring and configuring networking equipment, while keeping this traffic segregated and secure from user network traffic.
Step-by-step explanation:
The VLAN designed to support administrative access to networking devices is commonly known as a management VLAN. VLANs, or Virtual Local Area Networks, allow network administrators to segment the traffic on a network for improved performance and security. The management VLAN is specifically set up to allow IT personnel to log in to networking devices, such as switches and routers, remotely and securely for monitoring and configuration purposes.
In practice, administrators use this VLAN to access the management interface of networking equipment without exposing these critical interfaces to the normal user traffic that passes through the network. It is advisable to restrict access to the management VLAN to authorized devices and users, often implemented through access control lists (ACLs) or other forms of network security. By segregating the management traffic from the rest of the network, the risk of unauthorized access and potential security breaches can be minimized.
