What is the difference between the MAC address table and TCAM?
The MAC address table is stored in CAM (Content Addressable Memory), which is used for exact match lookups such as finding MAC addresses and their associated VLANs. TCAM (Ternary Content Addressable Memory), on the other hand, is used for more complex operations like ACL (Access Control List) and QoS (Quality of Service) lookups that require partial matches or longest-prefix matching.
There's a typo on D, should read "MAC are stored in CAM not TCAM...
Yes, the answer have a type mistake, in the first part is MAC not TCAM.
Absolutely agree with the typo.
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.
They are saying "contained" which is not wrong. You are right, MACs are in CAM and CAM contained in TCAM, and all of us are winners
the correct answer is B
i think so
wrong. https://notes.networklessons.com/memory-cam-and-tcam#:~:text=Now%20applying%20this%20to%20networking%20devices%2C%20when%20looking%20up%20an%20address%20in%20the%20MAC%20address%20table%2C
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.
Correct answer is D
D is correct for me
Correct is D
D is the correct answer
CAM stores only MAC addresses.
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
D is correct
Mac addresses are stored in the CAM. ACL and QOS are TCAM.
B - no way (see link below). D is OK
D is the correct answer https://www.ciscopress.com/articles/article.asp?p=101629&seqNum=4
Correct answer is D.
which one is good
I took the exam yesterday and passed it. I confirm the question as it appears in the exam. It is not the administrator's fault.
