What feature is more important at the core layer than at any other hierarchical network design layer?

  • easy access of end devices
  • aggregation of network links
  • QoS classification and marking
  • data security
  • packet switching speed

Explanation: Even though QoS classification and marking can be done at any layer, it typically is done at the access layer when possible. High availability easy access is also a function of the access layer. Data security can also be a part of any layer, but the access layer tends to focus on port security and the distribution layer on policy-based security. The core layer is considered to be the network backbone of the hierarchical network design model. Packet switching speed is critical for the core layer to provide high-speed, availability, and redundancy.
