Explanation

Port security (A) is a Layer 2 switch feature that restricts which MAC addresses are allowed to communicate through a specific physical switch port, directly preventing unauthorized devices from joining the network. A firewall (E) enforces access control policies at the network boundary, blocking unauthorized connections based on IP, port, or protocol rules. Anti-malware (B) protects against software threats but does not control network access. Certificates (C) authenticate identities but are not standalone network admission controls. An IDS (D) detects intrusions but does not block connections. A captive portal (F) redirects unauthenticated users to a login page (common in guest Wi-Fi) but does not prevent a node from physically connecting.
