The correct answer is D: TCAM entries are composed of value, mask, and result, and MAC address table entries are composed of value and results.
Here's why:
TCAM (Ternary Content Addressable Memory):
- Uses a three-component structure:
1. Value: The data to match
2. Mask: Determines which bits to compare
3. Result: The action to take when matched
- Allows for wildcard matching
- Optimized for fast lookups in networking devices
MAC Address Table:
- Uses a simpler two-component structure:
1. Value: MAC address
2. Result: Port number/interface
- Direct one-to-one mapping
- No masking capability needed
Why other options are incorrect:
A) The timing values are incorrect, and timing isn't an architectural difference
B) This describes population methods, not architectural differences
C) This incorrectly describes the components of both structures
A: No. this is exactly backwards.
B: No. EIGRP is considered a hybrid routing protocol.
C: No. EIGRP uses DUAL, OSPF uses SPF.
D: Yes. But poorly worded. External EIGRP has an AD of 170. Internal EIGRP has an AD of 90.
Example:
TCAM: deny ip 192.168.1.0 0.0.0.255 any
MAC:
MAC Address Port
