JNCIP-DC: Juniper Networks Certified Professional – Data Center (2023) — Question 2

You are deploying a 3-stage Clos IP fabric in your data center.
In this scenario, which statement is correct?

Answer options

• A. There is an eight-spine node limitation.
• B. Each spine node must be physically connected to all other spine nodes.
• C. No direct physical connections exist between leaf nodes.
• D. Each server-facing interface on a leaf node is always three hops away from other server-facing interfaces.

Correct answer: C

Explanation

The correct answer is C because in a Clos network architecture, leaf nodes are designed to connect to spine nodes without direct connections to each other. Option A is incorrect as there is no inherent limitation on the number of spine nodes, B is wrong because spine nodes do not require direct connections to each other, and D is misleading since the hop count can vary depending on the network topology.
