An engineer is creating a new fabric in Apstra. The engineer has selected the 'Spine & Leaf' reference design and is at the 'Add Devices' step. The engineer needs to add 4 spine switches and 20 leaf switches. The engineer has already added the 4 spines and 10 leaves. What is the next step to add the remaining 10 leaves?

Use the 'ZTP' tab to automatically add the remaining devices

Commit the current blueprint, then add the remaining devices in a new blueprint

Click 'Add Devices' again and select the remaining 10 leaf switches from the inventory

Create a new fabric and add all 24 devices to it

When selecting a data center reference design, which factor is most important for determining whether a superspine architecture is required?

The number of network administrators on staff

The total number of server ports needed in the data center

The brand of the server hardware

The color of the data center racks

A large enterprise is designing a new data center with Apstra. The design must support a mix of east-west traffic (server-to-server) and north-south traffic (to the internet). The enterprise expects east-west traffic to grow significantly over time. The network team is considering a 3-stage spine-and-leaf design with 8 spines and 64 leaves. What is the primary consideration when evaluating this design against the traffic requirements?

The number of leaf switches determines the bandwidth available for north-south traffic

The design must use a collapsed-core architecture to minimize latency for east-west traffic

The number of spine switches determines the bisectional bandwidth available for east-west traffic

The design must be changed to a 5-stage superspine to support any east-west traffic

A network engineer is comparing Apstra reference designs for a new data center. The engineer needs to support 500 racks, each with 2 leaf switches. The engineer is considering a 5-stage superspine design. What is the primary advantage of the superspine layer in this design?

It provides a dedicated layer for north-south traffic, improving internet connectivity

It eliminates the need for a separate overlay network

It allows the fabric to scale beyond the port capacity of a single spine tier

It reduces the number of leaf switches required in the fabric

Which components are typically defined within an Apstra data center reference design?

The organization's ITIL service management processes and change approval workflows

Only the physical cabling and power requirements for the data center

The list of all servers and their operating systems to be connected to the fabric

Topology, protocol choices, and operational policies
