ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

A financial services company uses an 802.1X-based NAC solution to verify that laptops have up-to-date antivirus signatures before they receive a production VLAN address. Auditors now insist that the NAC must also detect when a laptop becomes non-compliant during the workday and automatically move it to a quarantine network without user intervention. Which NAC feature meets this new requirement?

  • Port security that restricts the number of MAC addresses allowed on each switch port

  • Link-layer encryption using 802.1AE (MACsec) on all access links

  • One-time certificate authentication performed only during pre-admission

  • Periodic post-admission posture assessment with dynamic VLAN re-assignment
