Question

Difficulty: MediumNetwork Hardware Devices

A network technician is setting up a new branch office network connection. The Internet service provider delivers incoming internet access via a high-speed fiber-optic connection, and corporate policy requires centralized security monitoring and packet filtering before traffic reaches the internal wired network. Which TWO network hardware devices should the technician install at the site boundary to fulfill these requirements?

  1. Optical Network Terminal (ONT)Answer
  2. Hardware FirewallAnswer
  3. C
    Unmanaged Layer 2 Switch
  4. D
    DHCP Server Appliance

Answer

The technician should install an Optical Network Terminal (ONT) and a Hardware Firewall.
An Optical Network Terminal (ONT) terminates the incoming fiber-optic line and converts light pulses into standard electrical Ethernet signals. A Hardware Firewall is positioned at the perimeter to perform packet filtering and enforce corporate security policies on traffic entering or leaving the site.

Step-by-Step Solution

1
Determine the device required for incoming signal conversion.
The fiber-optic line requires an Optical Network Terminal (ONT).
Fiber lines transmit data via optical light pulses, which must be converted into electrical Ethernet signals before internal equipment can process the traffic.
2
Determine the device required for network security and traffic inspection.
A Hardware Firewall must be installed between the ISP drop/ONT and the internal network.
Hardware firewalls inspect and control inbound and outbound traffic based on defined security policies at the network edge.

Key Concept

Identifying network hardware devices used for media conversion and boundary security.
