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.

You are troubleshooting a traditional Clos Layer 3 IP fabric in your data center. You are reviewing the BGP configuration for one of your spine devices.



Referring to the exhibit, which statement is correct?

  1. This spine device will not install multiple next hops for remote destinations in its routing table.
  2. This spine device will not install any routes for remote destinations in its routing table.
  3. This spine device has three neighboring leaf devices.
  4. This spine device has three neighboring spine devices.

Answer(s): C



Referring to the exhibit, which statement is correct?

  1. Leaf1 has not learned any MAC addresses
  2. Leaf3 is the remote tunnel endpoint.
  3. One tunnel is servicing multiple VLANs
  4. Spanning Tree Protocol is disabled

Answer(s): C



You are asked to deploy an Ethernet bridging design in a data center with the criteria shown below.

- Routing must occur on the spine devices.
- VTEPs must terminate on the leaf devices.
- Facilitate inter-VLAN communication.
- Layer 2 gateways must be present on spine and leaf devices.

Which architecture should you use in this scenario?

  1. edge-routed bridging architecture
  2. centrally-routed bridging architecture
  3. bridge overlay architecture
  4. collapsed spine architecture

Answer(s): B
