The correct answer is B. Device Package. To reduce configuration overhead for integrating multiple identical L4-7 devices in ACI, a Device Package should be used to define the capabilities and integration points once.

Why each option

To reduce configuration overhead for integrating multiple identical L4-7 devices in ACI, a Device Package should be used to define the capabilities and integration points once.

AFunction profile

A Function Profile defines the various functions (e.g., firewall, load balancer) that a service device can provide, but the Device Package is the specific mechanism for templating the device integration itself.

BDevice PackageCorrect

A Device Package in ACI is a software module that defines the capabilities, properties, and configuration parameters of a specific L4-7 device type. By using a Device Package, you can abstract the device-specific configuration and integrate multiple instances of the same device type (e.g., ten identical firewalls) with minimal overhead, as the APIC uses the package to interact with and provision these devices.

CGraph Connector

A Graph Connector is a component within a Service Graph that defines how the service function chain connects to EPGs or other service functions, but it doesn't reduce the device configuration overhead directly.

DService Graph

A Service Graph defines the logical service function chain (e.g., EPG -> Firewall -> EPG), but the underlying integration and templating of the devices themselves for reuse is handled by the Device Package.
