A hospital is deploying a new IP Clos fabric for its campus. The network team wants to ensure that a failure of any single spine or leaf switch does not cause a complete outage for any connected device. They plan to connect each access switch (leaf) to multiple spine switches. What is the primary role of the spine switches in this design?

Spine switches are optional in a small campus and can be replaced by a single distribution switch.

Spine switches are the access layer where end devices connect, providing Power over Ethernet and port security.

Spine switches perform all routing and policy enforcement, while leaves only forward frames at Layer 2.

Spine switches provide the interconnection between all leaf switches and act as the backbone for all east-west traffic.

What is the primary purpose of the overlay network in a campus fabric?

To establish the physical routing protocol between switches

To provide a backup path for the underlay network

To provide logical segmentation and connectivity for tenants or VLANs

To replace the need for IP addressing on the physical network

A network engineer is troubleshooting a performance issue in an IP Clos fabric. They notice that traffic between two leaf switches is always taking the same path, even though multiple spine switches are available. What is the most likely cause?

The traffic is north-south, so it does not use the spine.

The spine switches are not connected to each other, preventing path diversity.

ECMP is not configured or is not working correctly, so traffic is not being load-balanced across the available paths.

The leaf switches are using STP to block redundant paths.

A network architect is planning a new campus fabric deployment. They need to ensure that the design supports multiple tenants with isolated Layer 2 domains, while also providing efficient use of the physical infrastructure. Which deployment consideration is most important to address?

Implementing VXLAN overlays with EVPN control plane to provide scalable Layer 2 segmentation.

Relying on ACLs on the spine switches to isolate tenants.

Using a single large VLAN for all tenants to simplify the network.

Deploying a separate physical network for each tenant.

When deploying an IP Clos campus fabric, what is a key consideration for IP addressing?

Use the same IP subnet for all switch-to-switch links to simplify routing

Use private IP addresses only for the underlay and public IPs for the overlay

Use a single loopback address for all switches to reduce IP consumption

Use a consistent, hierarchical IP addressing plan for loopback and link addresses
