Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 952
What is the architectural difference between the MAC address table and TCAM?
Answer options
- A. TCAM entries are stored for 600 seconds, and MAC address table entries are kept for 200 seconds.
- B. TCAM entries are populated using the ARP table, and the MAC address table is populated dynamically from outgoing frames.
- C. TCAM entries consist of VLAN, port ID and source MAC Address, and MAC address table entries consist of source MAC address end port ID.
- D. TCAM entries are composed of value, mask, and result, and MAC address table entries are composed of value and results.
Correct answer: D
Explanation
The correct answer, D, accurately describes the structure of TCAM and MAC address table entries. TCAM uses a combination of value, mask, and result for its entries, which allows for more complex matching, while the MAC address table generally consists of simpler entries with just value and results. The other options incorrectly describe the characteristics or functionality of TCAM and the MAC address table.
