Correct answer: CAM performs Layer 2 MAC lookups; TCAM performs Layer 3 address/ACL lookups., The MAC address table is stored in CAM, and ACL/QoS entries are stored in TCAM..
Why this is the answer
CAM (Content Addressable Memory) is optimized for exact-match lookups, making it ideal for storing MAC address tables for Layer 2 forwarding. TCAM (Ternary Content Addressable Memory) is more complex and allows for "don't care" bits in its lookups, enabling it to perform longest-prefix matching for IP routing and complex pattern matching for Access Control Lists (ACLs) and Quality of Service (QoS) policies. Therefore, CAM handles Layer 2 MAC lookups, while TCAM handles Layer 3 address lookups and ACL/QoS entries. The other options incorrectly assign these functions or memory types.
