Difficulty: HardNetwork Components Roles and Functions

An enterprise network engineer is designing a branch office infrastructure with three specific requirements:
1. Virtualized server workloads must run directly on bare-metal hardware without an intermediate operating system layer.
2. Local VLAN broadcast domains must be segmented and routed at hardware wire speed using specialized Application-Specific Integrated Circuits (ASICs).
3. Wireless Access Points (APs) managed by a centralized Wireless LAN Controller (WLC) must continue switching local client traffic locally if the WAN connection to the central controller fails.

Which combination of network component operational roles and architecture satisfies all of these requirements?

  1. Deploy Type 1 hypervisors on server hardware, perform inter-VLAN routing using Layer 3 switches, and configure lightweight APs in FlexConnect mode.Answer
  2. B
    Deploy Type 2 hypervisors on a host operating system, perform inter-VLAN routing using Layer 3 switches, and configure lightweight APs in FlexConnect mode.
  3. C
    Deploy Type 1 hypervisors on server hardware, perform inter-VLAN routing using Layer 2 switches, and configure lightweight APs in Local mode.
  4. D
    Deploy Type 1 hypervisors on server hardware, perform inter-VLAN routing using Layer 3 switches, and configure lightweight APs in Local mode.

Answer

Deploy Type 1 hypervisors on server hardware, perform inter-VLAN routing using Layer 3 switches, and configure lightweight APs in FlexConnect mode.
The correct selection combines Type 1 bare-metal hypervisors (which run directly on physical hardware), Layer 3 switches (which use dedicated ASICs to perform high-speed inter-VLAN routing across broadcast domains), and FlexConnect AP mode (which enables local traffic switching at branch offices during WLC controller outages).

Step-by-Step Solution

1
Identify the virtualization requirement.
Direct execution on bare-metal hardware without a host OS requires a Type 1 (bare-metal) hypervisor, such as VMware ESXi or Cisco UCS B-Series hypervisors.
Type 2 hypervisors require an underlying host OS (e.g., Windows/Linux), adding overhead.
2
Identify the routing component requirement.
Wire-speed inter-VLAN packet forwarding using hardware ASICs requires a Layer 3 switch (multilayer switch).
Layer 2 switches do not perform IP routing between subnets, while software-based routers lack hardware ASIC switching tables for high-density campus LANs.
3
Identify the wireless AP mode requirement.
FlexConnect mode (formerly REAP) allows lightweight APs to switch client data traffic locally when the CAPWAP control tunnel to the WLC is disrupted.
Local mode APs drop client traffic or cease forwarding when CAPWAP connection to the WLC drops.
