Q41. Which three items represent some of the components to implement Cisco VM-FEX for Cisco Unified Computing System Manager B-Series blades? (Choose three.)
A. Cisco VSM VM
B. VEM installed on the VMware vCenter server
C. VEM in the VMware ESX or ESXi host
D. Cisco Unified Computing System Manager version 1.2 or higher
E. VMware vCenter server
F. Fibre Channel VMFS volume
Answer: CDE
Q42. 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: C
Q43. When cabling a Cisco UCS 6200 Series Fabric Interconnect to disjoint Layer 2 networks, which option must be considered?
A. The fabric interconnect must be in switching mode.
B. You must first configure a LAN pin group.
C. Each VLAN is allowed across multiple disjoint uplinks.
D. Each vNIC can communicate to a single disjoint network.
Answer: D
Q44. Which of the following is true with respect to hardware failover or NIC teaming within a Cisco Unified Computing System?
A. Hardware failover is specified by the operating system.
B. An uplink failure when using automatic pinning requires that hardware failover for the server vNIC be disabled.
C. NIC teaming is controlled by the vNIC.
D. The hardware failover option that is available for Ethernet does not affect Fibre Channel traffic.
Answer: D
Q45. Which two VMware features will not allow an adapter to transition from Cisco VM-FEX standard mode to universal passthrough mode? (Choose two.)
A. VM Snapshot
B. Volume Shadow Copy
C. Storage vMotion
D. HA
E. Resource Reservations
Answer: AC

Q46. What is a true statement concerning automatic Fibre Channel pinning on a Cisco Unified Computing System 62XX Fabric Interconnect?
A. By default, uplink Fibre Channel interfaces are configured for VSAN trunking.
B. Using NPV, each downstream server will be pinned to an uplink port that is based on a PIN group.
C. The Fibre Channel pinning process is implemented differently than end-host MAC address pinning.
D. With VSAN trunking, the automatic pinning of server traffic to Fibre Channel uplink ports will be based on the server WWN.
Answer: D
Q47. In a standalone Cisco UCS C-Series server, which recommendations can be used to upgrade the BIOS?
A. Cisco IMC
B. Cisco UCS Manager
C. iFlash32 Utility
D. Flash ROM Utility
E. EFI Interface
F. Cisco Host Upgrade Utility
G. USB Flash Utility
Answer: F
Q48. Which item describes the failure scenario called a "split-brain" in the Cisco Unified Computing System?
A. failure of the Cisco Unified Computing System L1-L2 network
B. failure of a Cisco Unified Computing System Chassis Management Controller
C. failure of a Cisco Unified Computing System I/O module
D. failure of a Cisco Unified Computing System Fabric Interconnect
E. failure of a Cisco Unified Computing System Chassis Management Switch
Answer: A
Q49. How many links are there between a second-generation IOM (Cisco UCS 2204 or 2208) and a third-generation half-width blade (Cisco UCS B200 M3 or B22 M3) in a Cisco UCS system?
A. 1
B. 2
C. 4
D. 8
Answer: C
Q50. 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: A
