Zorluk: OrtaNetwork Hardware Devices

A network technician is establishing a newly created workstation segment in an office expansion. The client computers are connected to a network switch and can ping each other locally. However, all clients auto-configure with APIPA addresses (169.254.x.x169.254.x.x) and cannot reach the main corporate network or server resources on a different IP subnet. Which of the following network hardware devices should be installed to interconnect these distinct subnets and route network traffic between them?

  1. RouterCevap
  2. B
    Layer 2 switch
  3. C
    DNS server
  4. D
    Wireless access point

Cevap

A router is required because it operates at Layer 3 to route packets between different IP subnets and enable cross-subnet communication.
A router is the correct device because it operates at Layer 3 of the OSI model, making forwarding decisions based on IP addresses to move traffic between separate subnets.

Adım Adım Çözüm

1
Analyze the network symptoms and connectivity limitations presented in the scenario.
Workstations can communicate locally on the same switch, but have APIPA addresses (169.254.x.x169.254.x.x) and cannot reach resources on a separate IP subnet.
Communication within the same local segment confirms physical link integrity, while lack of cross-subnet access indicates a boundary boundary routing requirement.
2
Identify the OSI layer functionality needed to solve the problem.
Interconnecting different IP subnets requires Layer 3 (Network Layer) logical addressing and routing.
Layer 2 switches only forward frames using MAC addresses within a single broadcast domain.
3
Select the appropriate network hardware device matching Layer 3 routing requirements.
Selecting a router (or Layer 3 switch) fulfills the requirement to forward traffic between subnets.
Routers forward packets across network boundaries based on destination IP addresses.
