• Question 132:

  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
  C. Extending Layer 2 through a core causes path blocking by STP and has the risk of uncontrollable broadcast issues related to extending Layer 2 domains, and therefore should be avoided
  D. Server-to-server traffic typically travels between aggregation modules by way of the core, while backup and replication traffic remains within the aggregation module
  C. Extending Layer 2 through a core causes path blocking by STP and has the risk of uncontrollable broadcast issues related to extending Layer 2 domains, and therefore should be avoided
