Implementing Cisco Application Centric Infrastructure (DCACI) — Question 315

Which function does spine switch perform in the Cisco ACI fabric?

Answer options

• A. It connects to classic Ethernet devices in the multitier topology.
• B. It decapsulates VXLAN packets received from leaf switches.
• C. It stores all the entries of endpoints-to-VTEP mapping.
• D. It bridges tenant packets for applying network policies.

Correct answer: C

Explanation

The correct answer is C because the spine switch is responsible for storing endpoint-to-VTEP mapping entries, which is crucial for the operation of the ACI fabric. Option A is incorrect because spine switches do not directly connect to classic Ethernet devices. Option B is wrong as decapsulation is managed by leaf switches, not spine switches. Option D is also incorrect because policy application occurs primarily at the leaf switches, not on the spine switches.
