Passes inter-switch traffic which provides a layer of security. Which VLAN is described?

• A. VLAN
• B. Management VLAN
• C. Data Loss Prevention (DLP) Endpoint Software
• D. Network Flow (NetFlow)

Answer: (B)

Isolating administration traffic on a dedicated management VLAN creates a separate, more secure channel for inter-switch and device management communications. By keeping management plane traffic apart from user data, access to switch configurations and control interfaces is restricted to trusted administrators and secure protocols, reducing the chance that attackers can reach critical management functions through normal data paths. The other options don’t fit because a generic VLAN is just a segmentation concept without specifying management traffic isolation, DLP Endpoint Software is a security program rather than a VLAN, and NetFlow is a traffic monitoring protocol, not a VLAN for management security.
