    What is one distinction between Layer 2 and Layer 3 operations at the core?
    • A. 

      The Layer 2 core offers more control through QoS, the Layer 3 is limited to the use of routing protocols.

    • B. 

      The Layer 2 core manages its redundant links using STP, the Layer 3 core manages redundant The Layer 2 core manages its redundant links using a switching protocol, the Layer 3 core manages redundant links by using STP
