Zorluk: OrtaNetwork Components Roles and Functions

A network administrator is evaluating the core infrastructure components for a new branch office deployment, including a router, an unsegmented Layer 2 switch, a Next-Generation Firewall (NGFW), and virtualization servers. Which two statements accurately describe the operational roles and domain boundaries of these network components?

  1. A router isolates broadcast domains at each configured Layer 3 interface.Cevap
  2. A Next-Generation Firewall performs stateful inspection and application-level control up through Layer 7 of the OSI model.Cevap
  3. C
    A Layer 2 switch isolates broadcast domains on each physical port by default without requiring VLAN configuration.
  4. D
    A Type 2 hypervisor executes directly on host server hardware without an underlying operating system.

Cevap

A router isolates broadcast domains at each configured Layer 3 interface, and a Next-Generation Firewall performs stateful inspection and application-level control up through Layer 7.
Routers operate at Layer 3 and prevent Layer 2 broadcast traffic from propagating across interfaces, creating distinct broadcast domains. Next-Generation Firewalls expand upon traditional packet filtering by integrating deep packet inspection and application awareness up through Layer 7 of the OSI model.

Adım Adım Çözüm

1
Analyze the forwarding domain boundaries of routers versus Layer 2 switches.
Routers operate at Layer 3 and stop Layer 2 broadcasts from passing between interfaces. Layer 2 switches split collision domains per port but maintain a single shared broadcast domain by default.
Understanding domain separation is fundamental to network architecture.
2
Evaluate the functional scope of Next-Generation Firewalls (NGFW).
NGFWs inspect traffic up to Layer 7 (Application layer) to provide deep packet inspection and threat prevention.
Standard firewalls filter traffic up to Layer 4, while NGFWs inspect application payloads.
3
Differentiate hypervisor architecture classifications.
Type 1 hypervisors run directly on bare metal, while Type 2 hypervisors rely on a host operating system.
Proper classification prevents misidentifying virtualization platform architecture.
