A . core B . access C . distribution D . aggregatio

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. B .  “East-west” server-to-server traffic can travel between aggregation modules by way of the core，but backup and replication traffic typically remains within an aggregation module. C .  Load balancing， firewall service， and other network service are commonly integrated by the useof service modules that are inserted in the aggregation switched. D .  Virtualization tools allow a cost effective approach for redundancy in the network design byusing two or four VDCs from the same physical switch.

A . Voice needs to be assigned to the hardware priority queue. B . Voice needs to be assigned to the software priority queue. C . Call signaling must have guaranteed bandwidth service. D . Strict-priority queuing should be limited to 50 percent of the capacity of the link. E . At least 33 percent of the link bandwidth should be reserved for default best-effort class.
