How do TCAM entries differ architecturally from MAC address table entries?

TCAM (Ternary Content Addressable Memory) entries are designed for complex lookups, using a value, a mask, and a result. The mask allows for wildcard matching, enabling efficient policy-based forwarding, ACLs, and QoS. MAC address table entries, in contrast, are simpler value/result pairs, directly mapping a MAC address (value) to an egress port (result) for basic Layer 2 forwarding. The other options are incorrect: TCAM and MAC table aging times are configurable and not fixed as stated; TCAM entries are populated by various control plane protocols (like routing protocols for FIB, or ACLs), not directly from the ARP table; and while TCAM entries can include VLAN and port ID for more granular matching, MAC table entries primarily focus on source MAC and port for forwarding.
