A . A sequence will never generate duplicate values B . The MAXVALUE of a sequence can be equal to the MINVALUE C . It is not possible to create a sequence that generates a constant since the INCREMENT value must be greater than zero D .

A .  Server-to-server traffic always remains in the core layer. B .  The recommended practice is for the core infrastructure to be in Layer 3. C .  The boundary between Layer 2 and Layer 3 should be implemented in the aggregation layer. D .  The Cisco Express Forwarding hashing algorithm is the default， based on the IP address andLayer 4 port. E .  Core layer should run BGP along with an IGP because iBGP has a lower administrativedistance than any IGP.

A . Fast switching reducesa routers CPU utilization， compared to process switching B . All packets of a flow， except for the first packet， use the information in the fast cache C . It can be enabled with the interface command ip route-cache D . Fast switching uses a fast cache maintained in a router’s control plane E . The fast cache contains information about how traffic from different data flows should beforwarded F . Even though the fast switching is enabled， the first packet of a flow is still process switched
