Zorluk: OrtaNetwork Hardware Devices

A network technician is troubleshooting performance issues in a small department where several workstations are connected to a legacy networking component. Network traces show that incoming frames on any single port are mirrored to all active ports, causing frequent bandwidth saturation and packet collisions. The technician must replace this legacy equipment with a device that provides dedicated collision domains for each port while keeping all endpoints on the same Layer 2 flat subnet. Which of the following hardware devices should the technician install?

  1. Unmanaged Layer 2 switchCevap
  2. B
    Layer 3 router
  3. C
    DHCP server appliance
  4. D
    Automatic Private IP Addressing (APIPA) concentrator

Cevap

An unmanaged Layer 2 switch should be installed because it creates individual collision domains for each port by filtering traffic based on MAC addresses while maintaining a single local subnet.
The unmanaged Layer 2 switch is the ideal replacement for an Ethernet hub. Switches inspect destination MAC addresses in Layer 2 Ethernet frames to forward traffic exclusively to the specific port connected to the recipient node. This breaks up the single shared collision domain into separate collision domains for each port while keeping all endpoints on the existing local subnet.

Adım Adım Çözüm

1
Analyze the reported issue and current symptom
Frames received on one port are broadcast to all other ports, causing frequent packet collisions characteristic of a legacy Ethernet hub.
Ethernet hubs share a single collision domain across all connected ports.
2
Identify the required device functionality
The target device must microsegment the network by creating a dedicated collision domain per port while keeping all hosts within the same Layer 2 subnet.
Layer 2 switches inspect incoming Ethernet frame headers, store source MAC addresses in a CAM table, and forward frames only to the designated destination port.
3
Select the appropriate hardware device
An unmanaged Layer 2 switch satisfies the microsegmentation and Layer 2 broadcast requirements without requiring complex routing configurations.
Unmanaged switches operate at Layer 2 to isolate collision domains out of the box.
