Question

Difficulty: MediumNetwork Hardware Devices

A network technician is designing the infrastructure for a newly constructed satellite office. The network design requires connecting local wired workstations, supplying electrical power directly over data cables to mounted IP surveillance cameras, and providing perimeter network security with stateful packet filtering. Which of the following network hardware devices should the technician select to meet these requirements? (Select TWO.)

  1. Power over Ethernet (PoE) switchAnswer
  2. Hardware firewallAnswer
  3. C
    Unmanaged Layer 2 Ethernet switch without PoE
  4. D
    DHCP server appliance

Answer

The Power over Ethernet (PoE) switch and the hardware firewall are the required network hardware devices.
Selecting the Power over Ethernet (PoE) switch fulfills both the requirement to interconnect local workstations and the requirement to supply electrical power over data cabling to IP cameras. Selecting the hardware firewall addresses the requirement for perimeter protection and stateful packet inspection at the network border.

Step-by-Step Solution

1
Analyze the requirement for device connectivity and power delivery.
IP cameras require both network data communication and power delivery via standard Ethernet cabling.
Power over Ethernet (PoE) technology integrated into a network switch allows DC electrical current to travel alongside data frames over twisted-pair copper cables.
2
Analyze the requirement for perimeter network protection.
Stateful packet filtering at the network boundary requires a dedicated security appliance.
A hardware firewall inspects inbound and outbound traffic, keeping track of active connections to block malicious or unauthorized access at the perimeter.

Key Concept

Selecting network hardware devices based on functional requirements such as Power over Ethernet (PoE) and hardware security filtering.
