QuestionQ14

Network Stack

Which layer preserves unique logical source and destination addresses over the entire path between endpoints?

  • A Layer 5 – Session Layer
  • B Layer 4 – Transport Layer
  • C Layer 3 – Network
  • D Layer 2 – Data Link Layer
Explanation

The Network layer (Layer 3) provides logical addressing through source and destination IP addresses, allowing packets to be routed across multiple networks between end hosts. Data-link addresses are only used on a local link and change at each routed hop. Cisco notes that IP provides the logical addressing needed for communication across diverse networks.
