Explanation

In the Cisco three-tier data center architecture (core, aggregation, access), the aggregation layer serves as the convergence point for services. Service Module Integration (A) is a primary function - security appliances, load balancers, firewalls, and other service modules attach at this layer. Default Gateway Redundancy (B) is also provided here using protocols like HSRP or VRRP so servers always have a reachable gateway. High-speed packet switching backplane (C) is a core layer function. NIC teaming (D) is configured on individual servers at the access layer. Layer 3 domain definitions (E) are primarily managed at the core or between core and aggregation, not exclusively at aggregation.
