Q37. While the Nexus 7010 switches are configured with vPC, the Nexus 5000 switch connections to each Nexus 7010 are configured as regular port-channels. Which statement best describes the problem affecting the port channel on N5K1?
A. LACP is not configured to initiate negotiations.
B. N5K1 must also be configured with vPC.
C. load-balancing is not configured correctly on N5K1.
D. The remote ends of the port-channel on N5K1 cannot use the same interface

C. Only the mgmt 0 interface is allocated to the admin VDC.
D. All interfaces other than mgmt 0 are allocated to the default VDC.
E. The admin context can only be created on Supervisor 2/2E.
F. The admin VDC is a new feature in Cisco NX-OS version 6.0.
Q40. Cisco UCS users residing behind N5K2 are complaining about poor performance with a single LAN application in the data center. Which statement best explains what is wrong with N5K2?
A. Traffic balancing is based on the destination IP address.
B. Port channel members do not have equal bandwidths.
C. The trunk between the Nexus 5000 switches is filtering all VLANs.

Traffic balancing is based on the destination IP address
Use the “show port-channel load-balance” command to verify.
