Data Center PSE Professional Practice Test

The correct answer is that the APIC (Application Policy Infrastructure Controller) does indeed support inserting Layer 4 to Layer 7 devices in the data center. This capability is crucial because the APIC facilitates the integration of various services that can operate at different layers of the OSI model, thus enhancing the overall functionality and performance of applications deployed within the data center.

By supporting both Layer 4 and Layer 7 devices, the APIC enables organizations to implement load balancers, firewalls, and application delivery controllers that can manage traffic effectively at multiple layers. This versatility is essential for modern data center environments, where application performance, security, and availability are critical.

The APIC leverages service insertion to provide a seamless integration process for these devices, allowing them to be managed dynamically based on the application requirements. This means that as traffic patterns change, the APIC can automatically route traffic to the appropriate services, whether they are Layer 4-based (transport layer) or Layer 7-based (application layer).

This support for both Layer 4 and Layer 7 devices ensures that businesses can have a robust and adaptable infrastructure that caters to diverse application needs and traffic management strategies.
