A company is designing a new data center with Apstra. The company has a requirement that the fabric must support a large number of tenants, each with its own isolated network. The company is considering a 3-stage spine-and-leaf design. What is the primary mechanism in Apstra for providing tenant isolation in this design?

Virtual Networks (VNs) with VXLAN encapsulation

Separate BGP ASNs for each tenant

Dedicated leaf switches for each tenant

A separate spine-and-leaf fabric for each tenant

What is the purpose of device onboarding in the Apstra implementation process?

To create a backup of the switch configurations

To install the Apstra operating system on the switches

To assign IP addresses to the servers connected to the fabric

To add the physical switches to the blueprint so they can be managed and configured by Apstra

A financial services company is deploying a new data center. The compliance team requires that all traffic between servers in the same rack must not traverse any spine switch. The network team wants to use a standard Apstra reference design. Which design element must the company implement?

Use a 5-stage superspine design to ensure traffic stays within the rack

Place all servers in the same rack on the same VLAN and rely on the spine's Layer 2 forwarding

Enable 'Local Switching' on the leaf switches in the Apstra blueprint

Connect all servers in a rack to a single leaf switch and disable the uplinks to the spine

A company is designing a new data center with Apstra. The company has a requirement that the fabric must support both Layer 2 and Layer 3 tenant connectivity. The company also requires that the fabric must be able to scale to 100 racks. The network team is evaluating a 3-stage spine-and-leaf design. What is the primary consideration when evaluating this design against the Layer 2 and Layer 3 requirements?

The design must use OSPF for the underlay to support Layer 2

The design must support VXLAN for Layer 2 extension and BGP EVPN for Layer 3 routing

The design must use a 5-stage superspine to support both Layer 2 and Layer 3

The design must use a collapsed-core architecture to support Layer 2

An engineer is implementing a new Apstra fabric. The engineer has added all devices to the blueprint and assigned roles. The engineer now needs to configure the underlay. The engineer notices that the 'Underlay' tab shows a warning that the 'ASN' is not set for the fabric. What is the correct action to resolve this warning?

Set the ASN in the 'Devices' tab for each device individually before proceeding

Set a unique ASN for the fabric in the 'Underlay' tab, which will be used for BGP peering between spines and leaves

Ignore the warning, as the underlay will use OSPF instead of BGP by default

Re-create the blueprint and select a different reference design that does not require an ASN
