A large cloud provider is designing a new IP fabric with hundreds of leaf switches. The underlay must support ECMP and fast convergence, and the team wants to avoid the administrative overhead of assigning a unique ASN to every leaf. However, they also need to ensure that all paths are utilized. Which BGP design should be used?

Use the same ASN on all leaves and spines, and rely on BGP's built-in ECMP.

Use OSPF instead of BGP to avoid ASN management.

Use a unique private ASN for each leaf and a common ASN for all spines.

Use a single ASN for the entire fabric and enable BGP multipath.

A network architect is designing an IP fabric for a financial institution that requires high availability and minimal downtime during maintenance. The fabric will have 4 spines and 32 leaves. The team wants to perform software upgrades on the switches without causing traffic disruption. Which best practice should be implemented?

Upgrade one spine at a time, but do not upgrade leaves.

Upgrade all switches simultaneously during a maintenance window.

Rely on graceful Routing Engine switchover (GRES) only.

Use nonstop bridging and nonstop routing (NSB/NSR) to allow hitless upgrades.

A network administrator is configuring a new IP fabric. To ensure consistent configuration and simplify operations, the team wants to automate the deployment of leaf and spine switches. Which best practice should be applied?

Use a single configuration file for all switches, including hostnames and IP addresses.

Rely on dynamic routing protocols to automatically configure interfaces and VLANs.

Use a configuration management tool like Ansible to push the same base configuration to all switches, then apply role-specific variables.

Manually configure each switch to ensure unique settings are applied correctly.

In an IP fabric, what is the primary function of the underlay network?

To encrypt all data traffic within the data center

To establish physical connectivity and routing between fabric devices

To provide a management plane for network devices

To provide virtual network overlays for tenants

What is the primary impact of adding a new leaf switch to an existing spine-and-leaf IP fabric?

It reduces the overall fabric bandwidth

It increases the available server capacity without changing the existing topology

It requires reconfiguration of all existing spine switches

It increases the number of hops between existing leaves
