yes, agree with D as correct answer.
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.
MAC Address Table is a basic structure used to store MAC addresses and their associated switch ports for Ethernet frame forwarding in a Layer 2 network.
TCAM is a specialized memory used for performing complex, high-speed lookups based on multiple criteria (like IP address matching, ACL rules, etc.) in Layer 3 and higher network operations.
D is the correct answer!, CAM is for exact match based searching. For example – the MAC address table whilst TCAM is for longest match searching eg acl or ip routing
CAM requires an exact match to return a result. This means that the value that is being searched for (in binary) must contain either 0s or 1s. TCAM does not require an exact match, and is queried using 0s, 1s, and Xs, where X essentially means “anything” (that is, either 0 or 1). It's kind of like a wildcard state.
Correct is D. CAM contains the MAC address table and their VLANS. TCAM is used for ACL and QoS purposes.
TCAM is the table that supports partial matches, for ACL purposes.
People answering option B as correct are badly wrong. Routing lookups are made in RIB, wich is the routing database.
