What type of VLAN passes inter-switch traffic providing an additional layer of security?

The management VLAN is specifically designated for network management traffic, allowing administrators to manage the network devices securely and efficiently. By isolating management traffic from regular user traffic, it helps in safeguarding sensitive administrative access from potential attacks that may target the data or user VLANs.

Using a management VLAN enhances security because it limits access to management interfaces and protocols only to specific devices and users who are authorized to perform configuration or management tasks. This segregation minimizes the risk of unauthorized access and potential breaches since the management traffic cannot be easily intercepted by users on other VLANs.

The other options do not serve the same purpose in the context of inter-switch traffic and security. For instance, a Virtual Local Area Network (VLAN) is a broader concept referring to logically segmented networks but does not specifically relate to management or security layers. An Out of Band VLAN typically refers to a network that is separate from the normal operations of a production network for maintenance and diagnostics, but it does not provide the same targeted management security and isolation benefits. Data Loss Prevention (DLP) VLAN is not a standard term used in networking for security purposes.
