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.)
simpler deployment for additional switch equipment
less required equipment to provide the same performance levels
easier to provide redundant links to ensure higher availability
reduced cost for equipment and user training

What is one function of a Layer 2 switch?
determines which interface is used to forward a frame based on the destination MAC address
forwards data based on logical addressing
duplicates the electrical signal of each frame to every port
learns the port assigned to a host by examining the destination MAC address
determines which interface is used to forward a frame based on the destination MAC address
