A data center architect is designing a new IP fabric in Apstra for a customer who runs a three-tier application. The customer requires two types of leaf devices: one for server connectivity (with 48x10G downlinks and 4x100G uplinks) and one for storage connectivity (with 24x25G downlinks and 4x100G uplinks). Both leaf types will connect to the same pair of spine switches. The architect wants to minimize the number of logical devices to maintain. What should the architect do?

Use the built-in default leaf logical device and accept that the storage leaf will have unused interfaces

Create one leaf logical device with 48x10G downlinks and override the speed to 25G on the storage leaf's device profile

Create two separate leaf logical devices, one for each hardware model, and assign them to the respective device profiles

Create a single generic logical device with 48 interfaces and assign roles per interface during device profile application

What does the 'breakout' property of an interface in a logical device allow?

Enabling the port to automatically negotiate speed with the peer

Splitting a high-speed port into multiple lower-speed ports

Combining multiple ports into a single logical port channel

Allowing the port to be used for both uplink and downlink roles

A network engineer is creating a logical device for a leaf switch that has 48 ports. The engineer wants to use 12 of these ports as 4x10G breakouts to connect to servers, while the remaining 36 ports will be used as 10G downlinks. The switch hardware supports breakout on all 48 ports. What should the engineer configure in the logical device?

Define all 48 interfaces with breakout enabled (4x10G)

Define 48 interfaces with breakout enabled and then disable breakout on 36 of them after applying the logical device

Define all 48 interfaces with breakout disabled (1x10G) and rely on the device profile to enable breakout later

Define 12 interfaces with breakout enabled (4x10G) and 36 interfaces with breakout disabled (1x10G)

What is the purpose of validating a logical device in Apstra?

To check that the logical device's configuration is free of syntax errors

To confirm that the logical device is using the latest version of the Apstra software

To ensure the logical device is compatible with the hardware capabilities of the device profile

To verify that the logical device has been assigned to at least one device in the fabric
