Difficulty: HardNetwork Components Roles and Functions

An enterprise network team is implementing a hyper-converged rack architecture containing Type 1 bare-metal hypervisors, Layer 3 access switches, and Next-Generation Firewalls (NGFWs). Which two statements accurately describe the operational roles and traffic-handling boundaries of these components? (Select two.)

  1. The Type 1 hypervisor executes directly on physical server hardware to manage virtual machine resources and provision virtual switches without relying on an underlying host operating system.Answer
  2. B
    Virtual switches integrated within hypervisors create separate broadcast domains for each virtual machine connected to the same VLAN.
  3. Layer 3 switches separate Layer 2 broadcast domains by routing traffic between VLANs, whereas the NGFW tracks connection state to perform deep packet inspection and enforce security policies.Answer
  4. D
    The Type 1 hypervisor requires a pre-installed primary operating system kernel to translate virtual switch forwarding calls to physical network adapters.

Answer

The statement stating that Type 1 hypervisors execute directly on physical hardware without a host OS and the statement that Layer 3 switches terminate broadcast domains while NGFWs perform stateful connection inspection are both correct.
Type 1 hypervisors run bare-metal without an underlying host operating system, direct-managing hardware and internal virtual switching. Additionally, Layer 3 switches isolate broadcast domains by establishing routing boundaries between VLANs, while NGFWs perform stateful inspection and deep packet security enforcement across network zones.

Step-by-Step Solution

1
Analyze the architecture of Type 1 hypervisors relative to virtual switching.
Type 1 hypervisors run directly on bare metal without a host OS, providing hardware virtualization and integrated L2 virtual switching for hosted virtual machines.
Differentiating Type 1 (bare-metal) from Type 2 (hosted) hypervisors is critical when assigning infrastructure management responsibilities.
2
Evaluate the switching domain properties of virtual and physical switches.
Switches separate collision domains per switch port, but a VLAN defines a single Layer 2 broadcast domain across both physical and virtual switch ports.
Broadcast frames flood across all ports assigned to the same VLAN regardless of whether the switch is physical or virtual.
3
Compare Layer 3 switch routing capabilities with Next-Generation Firewall functional roles.
Layer 3 switches terminate Layer 2 broadcast boundaries at VLAN SVIs and handle high-speed inter-VLAN routing, whereas NGFWs maintain connection state tables and inspect payload contents up to Layer 7.
Network component roles must be distinctly allocated between Layer 3 throughput forwarding and stateful security boundary enforcement.
