Question: 8

You have a Cisco UCS B200 M2 server configured with 12 4-GB DDR3 1333-MHz dualvoltage
memory DIMMs. You learned that the server memory speed is running at 1066
MHz instead. How can you configure the server to run at maximum memory speed?

A. You cannot configure memory speed of 1333 MHz. The maximum memory speed of a
Cisco UCS B200 M2 server with 12 4-GB DIMM is 1066 MHz.
B. Memory speed of the ESX host is configurable on VMware vCenter.
C. Create a BIOS policy. In the RAS Memory BIOS settings, select Performance Mode for
LV DDR Mode.
D. On the CIMC of the Cisco UCS B200 M2, select 1333 MHz in the Memory Speed option.

Which two are true with respect to the switching modes on the Cisco Unified Computing

System 62XX Fabric Interconnect? (Choose two.)

B. For northbound traffic, server MAC addresses are statically pinned to an uplink; the return path is controlled by the unified fabric switches.

C. A fabric interconnect port in Ethernet switching mode appears to the uplink switch as a host with many MAC addresses.

D. Server-to-server traffic on a common VLAN are locally switched by the fabric

interconnect and not the northbound switches.

E. A MAC forwarding table is not used to forward traffic to the uplink switch.

F. A MAC address forwarding table is maintained for server-to-server communications across VLANs.
