Q1. If a customer wants to maximize the capability of server mobility with the Cisco UCS deployment, what two options are Cisco recommended? (Choose two.) 

A. Configure a server inheritance policy. 

B. Configure a Virtual Media boot. 

C. Configure a hardware-based service profile with burned-in addresses and identities. 

D. Configure boot from SAN. 

E. Configure service profiles with resource pools. 

Answer: DE 

Q2. The Cisco UCS 6200 Series Fabric Interconnects offer a new feature that allows dynamic port allocation for all of the 10 Gigabit Ethernet interfaces. What are these ports called? 

A. universal ports 

B. flex ports 

C. unified ports 

D. converged ports 

Answer:

Q3. How does a Cisco Unified Computing System react when configured for disjoint Layer 2 domains? 

A. Automatic pinning is disabled; VLAN membership must be statically pinned to the uplink ports. 

B. VLANs must be divided between the fabric interconnects using PIN groups. 

C. The VLAN traffic for a disjoint network can only travel along an uplink that is specifically assigned to this VLAN and is selectively excluded from all other uplinks. 

D. When you configure disjoint Layer 2 networks, you must assign VLANs to uplink interfaces. 

Answer:

Q4. Which network driver is required on a VMware ESXi 5.0 host for a vNIC to enter Cisco VM-FEX universal passthrough mode? 

A. VMXNET3 

B. Vlance 

C. Flexible 

D. E1000e 

E. VMXNET5 

Answer:

Q5. In the Create Dynamic vNIC Connection Policy dialog box, there is a configurable field titled Protection. What is the significance of the three choices for Protection? 

A. allows reserve vNICs to be allocated out of the spares pool 

B. enables hardware-based failover 

C. enables static binding of the VM port profile to dynamic vNICs 

D. selects the primary fabric association for dynamic vNICs 

E. allows dynamic vNICs to be reserved for fabric failover 

Answer:

Q6. You have a Cisco UCS B200 M2 server configured with 12 4-GB DDR3 1333-MHz dual-voltage 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. 

Answer:

Q7. Which of the following scenarios accurately demonstrate how the Cisco Unified Computing System ensures that a firmware upgrade is minimally disruptive to the data center unified fabric? 

A. If an I/O module is upgraded to a version that is incompatible with its fabric interconnect, the fabric interconnect can automatically reactivate the I/O module to a compatible version. 

B. If components like server BIOS, HBA, and RAID controller firmware are unsuccessfully updated through direct firmware updates, the update process will fall back to a host firmware package that is associated with the service profile. 

C. If an update of the subordinate fabric interconnect leaves it in a nonusable state, the primary fabric interconnect will automatically be updated to ensure that one fabric interconnect is running the most recent firmware. 

D. After Cisco Unified Computing System Manager upgrades the subordinate node, only then is the active management node automatically synchronized. 

Answer:

Q8. Which of the following is the most accurate concerning the link configuration between Cisco Unified Computing System 22XX I/O modules and Cisco Unified Computing System 62XX Fabric Interconnects? 

A. Port channels are always recommended when using source-dest-mac load balancing. 

B. The addition of links to a port channel requires a reacknowledgement. 

C. You cannot mix and match discrete links and port channeling for different chassis when using 22XX. 

D. Port channels do not require a Global Chassis Discovery policy. 

Answer:

Q9. Which two options occur when a server discovery policy is invoked? (Choose two.) 

A. executes the qualification in the server discovery policy against the server 

B. applies the scrub policy to the server 

C. analyzes the inventory of the server 

D. assigns the server to the selected organization, if configured 

E. creates a service profile for the server with the identity burned into the server at time of manufacture 

Answer: AC 

Q10. Which adapter is capable of supporting VM-FEX? 

A. VIC 1280 

B. Cisco UCS M61KR-I 

C. Cisco UCS M72KR 

D. Cisco UCS M51KR-B
