A network designer must provide a rationale to a customer for a design which will move an enterprise from a flat network topology to a hierarchical network topology. Which two features of the hierarchical design make it the better choice? (Choose two.)

  1. lower bandwidth requirements
  2. reduced cost for equipment and user training
  3. easier to provide redundant links to ensure higher availability
  4. less required equipment to provide the same performance levels
  5. simpler deployment for additional switch equipment

Explanation: A hierarchical design for switches helps network administrators when planning and deploying a network expansion, performing fault isolation when a problem occurs, and providing resiliency when traffic levels are high. A good hierarchical design has redundancy when it can be afforded so that one switch does not cause all networks to be down.
