Difficulty: MediumNetwork Hardware Devices

A network administrator is organizing network hardware components for a new office expansion project. Match each network hardware device to its primary function or capability in a corporate network environment.

  • Managed SwitchProvides packet switching and allows network administrators to configure VLANs, port security, and SNMP monitoring.
  • PoE InjectorSupplies electrical power over standard Ethernet cable to a single remote device when the connecting switch port lacks power capabilities.
  • Media ConverterTransitions network signals between disparate physical transmission media, such as copper twisted-pair and fiber-optic cabling.
  • Hardware FirewallFilters incoming and outgoing network traffic at the perimeter based on pre-established security rules.

Answer

Managed Switch matches with configurable VLAN and SNMP capabilities; PoE Injector matches with supplying power to a single device over Ethernet; Media Converter matches with transitioning signals between cable types like copper and fiber; Hardware Firewall matches with filtering perimeter traffic based on security rules.
Each device is matched to its primary physical or logical networking role: Managed Switches for configurable Layer 2/3 traffic control and VLANs, PoE Injectors for inline electrical power delivery, Media Converters for physical media translation (copper to fiber), and Hardware Firewalls for security rule enforcement at network boundaries.

Step-by-Step Solution

1
Identify the function of the Managed Switch.
Managed switches offer advanced features like VLAN segmentation, port mirroring, and SNMP management.
Unmanaged switches lack administrative interfaces, whereas managed switches allow active configuration of network parameters.
2
Identify the function of the PoE Injector.
PoE injectors combine data from a non-PoE port with electrical power onto a single Ethernet cable.
This enables powering end devices in locations without nearby power outlets when standard switch ports lack native PoE.
3
Identify the function of the Media Converter.
Media converters transition data signals between different physical mediums, such as UTP to fiber.
This is essential when expanding cable runs beyond copper distance limits (100 meters).
4
Identify the function of the Hardware Firewall.
Hardware firewalls inspect and filter network traffic according to predefined security rules at the network boundary.
Perimeter firewalls protect internal assets from unauthorized external access.
