Answer “E” is incorrect.
Quote: The only disadvantage of the collapsed-core topology is its scale limit relative to the core-edge topology. While the collapsed-core topology can scale quite large, the core-edge topology should be used for the largest of fabrics. However, to continually scale the collapsed-core design, one could convert the core to a core-edge design and add another layer of switches.
