Which unique characteristics of the Data Center Aggregation layer must be considered by an Enterprise Campus designer？（）

• A、 Layer 3 routing between the Access and Aggregation layers facilities the ability to span VLANsacross multiple access switches， which is a requirement for many server virtualization andclustering technologies.
