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

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

Answer(s): D



You are deploying an EBGP IP fabric. In this scenario, which statement is true?

  1. Each spine should peer with every other spine using physical addresses.
  2. Each spine should peer with each leaf using loopback addresses.
  3. Each spine should peer with every other spine using loopback addresses.
  4. Each spine should peer with each leaf using physical addresses.

Answer(s): D



You are asked to scale the available bandwidth within your Clos data center network to support more east-west traffic. In this scenario, what are two ways to accomplish this task? (Choose two.)

  1. Add leaf devices to increase available paths and bandwidth
  2. Use aggregated interfaces in the fabric.
  3. Add spines to increase available paths and bandwidth.
  4. Interconnect all spines to increase available paths and bandwidth.

Answer(s): A,C

Explanation:

In a Clos data center network, scaling the available bandwidth to support more east-west traffic can be effectively achieved by either adding more leaf devices (A) or more spine devices (C). Adding leaf devices increases the total number of endpoints in the network, thereby providing additional paths and bandwidth for east-west traffic. Similarly, adding spine devices increases the interconnectivity within the network, offering more paths for traffic to flow through, which helps in handling higher volumes of east-west traffic. Both approaches work towards enhancing the overall capacity and efficiency of the network.

Which two statements are correct about a spine and leaf-based IP fabric? (Choose two.)

  1. Traffic is diverted within the fabric when a device or link fails.
  2. There is no need for redundancy at the server level.
  3. Leaf switches broadcast frames to all other leaf devices.
  4. Clos networks demonstrate good scaling features.

Answer(s): A,D

Explanation:

In a spine and leaf-based IP fabric, when a device or link fails, the traffic is rerouted within the fabric (A), ensuring high availability and resiliency. This architecture is designed to dynamically adapt to changes and reroute traffic as needed. Furthermore, Clos networks, which are the basis for spine-leaf architectures, demonstrate good scaling features (D) as they allow for easy expansion of the network by adding more spine or leaf switches without significant changes to the existing infrastructure.
