A.

B.
The SAN core connects to the network aggregation layer.

C.
Separate links with the same I/O are used for SAN and LAN traffic.

D.
Storage devices are accessed via FCoE over the LAN network.

Explanation:
The Aggregation layer of the data center provides connectivity for the Access layer switches in the
server farm, an aggregates them into a smaller number of interfaces to be connected into the Core
layer. In most data center environments, the Aggregation layer is the transition point between the
purely Layer 3 routed Core layer, and the Layer 2-switched Access layer. 802.1Q trunks extend the
server farm VLANs between Access and Aggregation layers. The Aggregation layer also provides a
common connection point to insert services into the data flows between clients and servers, or
between tiers of servers in a multi-tier application.
