An enterprise network architecture incorporates multiple specialized physical and virtual components across campus, data center, and edge segments. Match each network component on the left to its primary operational function and forwarding behavior on the right.
- Next-Generation Firewall (NGFW)Performs deep packet inspection up to Layer 7, enforcing stateful access control policies and threat prevention across security zones.
- Type 1 Bare-Metal HypervisorRuns directly on host hardware to manage virtualized computing resources and provides internal Layer 2 software switching between virtual machines.
- Wireless LAN Controller (WLC)Centralizes control-plane operations, dynamic radio frequency (RF) management, and SSID policy deployment for lightweight access points.
- Layer 3 SwitchExecutes hardware-accelerated wire-speed packet forwarding between local VLANs using specialized Application-Specific Integrated Circuits (ASICs).
Answer
Next-Generation Firewall (NGFW) matches deep packet inspection up to Layer 7 stateful security enforcement. Type 1 Bare-Metal Hypervisor matches direct hardware execution for managing virtual machines and vSwitches. Wireless LAN Controller (WLC) matches centralized control-plane and dynamic RF management for lightweight APs. Layer 3 Switch matches ASIC-driven, wire-speed inter-VLAN hardware routing.
Each component is accurately paired with its architectural plane and operational behavior: Next-Generation Firewalls handle stateful Layer 7 security inspection; Type 1 Hypervisors execute on bare metal to manage compute virtualization and vSwitches; Wireless LAN Controllers centralize control-plane RF and policy administration for APs; and Layer 3 Switches perform ASIC-accelerated inter-VLAN packet routing at line rate.
