Exam SY0-701 Topic 1 Question 296 Discussion

Port security is the best mitigation technique for preventing an attacker from flooding the MAC address table of network switches. Port security can limit the number of MAC addresses learned on a port, preventing an attacker from overwhelming the switch's MAC table (a form of MAC flooding attack). When the allowed number of MAC addresses is exceeded, port security can block additional devices or trigger alerts.
Load balancer distributes network traffic but does not address MAC flooding attacks.
IPS (Intrusion Prevention System) detects and prevents attacks but isn't specifically designed for MAC flooding mitigation.
NGFW (Next-Generation Firewall) offers advanced traffic inspection but is not directly involved in MAC table security.
