Zorluk: OrtaOSI Model Layers and Functions

A network administrator is evaluating protocol functions within an enterprise network infrastructure. Which of the following operations take place specifically at the Network Layer (Layer 3) of the OSI model? (Select TWO.)

  1. Determining optimal path selection for data delivery across interconnected subnets using routing algorithmsCevap
  2. Formatting data units into IP packets and applying logical source and destination addressesCevap
  3. C
    Performing physical hardware addressing and framing using Media Access Control (MAC) addresses
  4. D
    Managing end-to-end segment sequencing, flow control, and port-based process multiplexing

Cevap

Determining optimal path selection for data delivery across interconnected subnets using routing algorithms, and formatting data units into IP packets and applying logical source and destination addresses.
The Network Layer (Layer 3) is responsible for end-to-end logical host addressing and path determination (routing) across interconnected subnets. Consequently, encapsulating data into packets with logical IP addresses and routing those packets across networks are the correct Layer 3 operations.

Adım Adım Çözüm

1
Identify the primary scope of the Network Layer (Layer 3) in the OSI model.
Layer 3 handles logical addressing and path determination across multi-segment networks.
The core purpose of Layer 3 is to enable inter-network host communication beyond local broadcast domains.
2
Analyze each proposed function against OSI layer boundaries.
Routing paths and IP packet addressing belong to Layer 3. MAC addressing belongs to Layer 2, while TCP/UDP port multiplexing and flow control belong to Layer 4.
Differentiating physical hardware addresses, logical network addresses, and transport ports clarifies proper layer assignment.
