When using spine and leaf fabric architectures, what is the role of each device? (Choose two.)

A.

Spine nodes are used for host connectivity.

Answers
A.

Spine nodes are used for host connectivity.

B.

Spine nodes are used for transit to other leaf nodes.

Answers
B.

Spine nodes are used for transit to other leaf nodes.

C.

Leaf nodes are used for traffic to other leafs.

Answers
C.

Leaf nodes are used for traffic to other leafs.

D.

Leaf nodes are used for host connectivity.

Answers
D.

Leaf nodes are used for host connectivity.

Suggested answer: B, D

Explanation:

In a spine-leaf fabric architecture, which is commonly used in data center designs, each device has a distinct role to ensure efficient and scalable network traffic flow.

Step-by-Step Breakdown:

Spine Nodes:

The spine nodes form the backbone of the fabric and are responsible for transit traffic between leaf nodes. They connect to every leaf switch and provide multiple paths for traffic between leaf nodes, ensuring redundancy and load balancing.

Leaf Nodes:

The leaf nodes are used for host connectivity. These switches connect to servers, storage, or edge routers. They also connect to the spine switches to reach other leaf switches.

Reference:

Spine-Leaf Architecture: In Juniper's IP fabric designs, spine switches handle inter-leaf communication, while leaf switches manage host and endpoint connectivity.
