Zorluk: KolayNetwork Components Roles and Functions

A network engineer needs to deploy a security device at the enterprise perimeter that inspects packet headers and payloads, maintains connection state tables, and enforces security policies to permit or deny traffic. Which network component fulfills this specific role?

  1. Stateful FirewallCevap
  2. B
    Layer 2 Switch
  3. C
    Type 2 Hypervisor
  4. D
    Link Layer Discovery Protocol (LLDP) agent

Cevap

Stateful Firewall
A stateful firewall is specifically designed to enforce perimeter security by monitoring active connection states and comparing incoming and outgoing traffic against access rules.

Adım Adım Çözüm

1
Identify the primary requirement in the scenario
The scenario calls for inspecting traffic, maintaining connection state tables, and enforcing security policies.
Security policies and state tracking are defining characteristics of network security devices.
2
Match the functional requirements to network component roles
A stateful firewall continuously tracks session states (such as TCP handshakes) and applies security rules to filter traffic at the network edge.
Switches, hypervisors, and discovery protocols perform forwarding, virtualization, and management neighbor identification respectively, rather than stateful security enforcement.
