ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

During a security review of a campus network, you discover that switch management interfaces currently share the same Layer-3 infrastructure that carries ordinary user traffic. To minimize the chance that a compromised endpoint can influence routing or reconfigure devices, which network design change most directly enforces a clear separation between the control plane and the data plane?

  • Place every switch and router management interface into a dedicated out-of-band network that is accessible only from hardened administrative jump hosts.

  • Apply port security to restrict each access port to a single learned MAC address.

  • Replace distribution switches with Layer-2-only models to remove routing capabilities.

  • Enable Spanning Tree Protocol with root guard on all trunk links.
