QUESTION 81

What design will effect traffic flows in the Data Center Core layer?

 

A.

The domain needed to extend a VLAN from one switch to another is determined at the core layer

B.

With a 3 layer (Access, Aggregation, Core) design the Layer 2 domain must be configured across the Core for VLAN extension to occur
