Where do servers typically attach in a VSX deployment at the Access-Aggregation layer?

• A. Core switches
• B. Wireless controllers
• C. Access/Aggregation switches
• D. Edge routers

Answer: (C)

In a VSX fabric, servers connect to the access/aggregation layer because this is the edge where end hosts are given direct, policy-controlled access to the network. The two VSX switches act as a single logical switch, providing a loop-free, highly available path for all east–west traffic. Placing servers on the access switches ensures their traffic is immediately part of the VSX fabric and can be dual-homed or uplinked to both VSX peers without creating loops. This setup also keeps server traffic close to the edge where VLANs, ACLs, QoS, and other policies are applied, while the aggregation/VSX pair handles the resilient, high-capacity uplinks toward the core. Choosing core switches would place servers too far from the edge where they typically need immediate access policies; wireless controllers are for wireless management and traffic separation, not primary server attachment points; edge routers handle WAN connectivity, not internal data-center server access.
