What is the differences between TCAM and the MAC address table?
A . The MAC address table is contained in TCAM ACL and QoS information is stored in TCAM
B . The MAC address table supports partial matches. TCAM requires an exact match
C . Router prefix lookups happens in CAM. MAC address table lookups happen in TCAM.
D . TCAM is used to make Layer 2 forwarding decisions CAM is used to build routing tables

Answer: A

Explanation:

https://community.cisco.com/t5/networking-documents/cam-content-addressable-memory-vs-tcam-ternary-content/ta-p/3107938

When using Ternary Content Addressable Memory (TCAM) inside routers it’s used for faster address lookup that enables fast routing.

In switches Content Addressable Memory (CAM) is used for building and lookup of mac address table that enables L2 forwarding decisions.

Besides Longest-Prefix Matching, TCAM in today’s routers and multilayer Switch devices are used to store ACL, QoS and other things from upper-layer processing.
