What is a characteristic of the two-tier spine-leaf topology of the Cisco ACI fabric architecture?
- The spine and leaf switches are always linked through core switches.
- The spine switches attach to the leaf switches and attach to each other for redundancy.
- The leaf switches always attach to the spines and they are interlinked through a trunk line.
- The leaf switches always attach to the spines, but they never attach to each other.
Explanation: In the two-tier spine-leaf topology used by Cisco ACI, the architecture follows a specific connection rule: every leaf switch must connect to every spine switch, but leaf switches never attach directly to one another. This design ensures that all devices connected to the fabric are exactly one hop away from each other, providing predictable and low-latency communication. Similarly, spine switches only connect to leaf switches and core switches, not to other spine switches.
