Zorluk: OrtaNetwork Hardware Devices

A network administrator is organizing equipment and cabling within a newly established telecommunications closet. Match each network hardware device to the functional description that best fits its role in the infrastructure.

  • Patch PanelTerminates structured horizontal copper cable runs from wall outlets and provides a centralized point for organized jumper connections to network switches.
  • Layer 3 SwitchEvaluates packet IP header information to forward traffic between different VLAN subnets while operating at high switching speeds.
  • Hardware FirewallPerforms stateful packet inspection at the network perimeter to block unauthorized external access based on preconfigured security rules.
  • Power over Ethernet (PoE) InjectorInserts direct electrical power onto a single Category 6 Ethernet cable run to supply a distant network endpoint that lacks an adjacent AC power outlet.

Cevap

Patch Panel matches the termination of structured horizontal cabling; Layer 3 Switch matches evaluating IP headers to route between VLAN subnets; Hardware Firewall matches stateful packet inspection at the perimeter; PoE Injector matches inserting electrical power onto a single Ethernet cable run.
Each device performs a distinct physical or logical function within structured cabling and network management. Patch panels organize physical cable terminations. Layer 3 switches process network-layer IP packet headers for inter-VLAN routing. Hardware firewalls perform stateful security filtering at the perimeter. PoE injectors add electrical power directly to standard Ethernet lines for remote device power delivery.

Adım Adım Çözüm

1
Identify the primary role of cabling consolidation equipment.
The Patch Panel terminates horizontal runs from office space outlets into an organized rack arrangement.
Patch panels provide physical cabling organization and prevent wear on permanently installed cables.
2
Identify the hardware responsible for high-speed inter-VLAN routing.
The Layer 3 Switch performs packet switching and IP-based routing functions across network subnets.
Layer 3 switches operate at both Layer 2 (data link) and Layer 3 (network) to route inter-VLAN traffic without sending all data through an external router.
3
Identify perimeter network protection devices.
The Hardware Firewall performs stateful inspection to filter unauthorized access.
Firewalls evaluate traffic flows against configured access control lists at the network boundary.
4
Identify inline power supplying hardware.
The Power over Ethernet (PoE) Injector supplies DC power inline over an Ethernet run to power endpoints.
Midspan PoE injectors add power to individual twisted-pair runs when the main network switch does not supply native PoE port power.
