Q1. 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:

Q2. 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:

Q3. Which policy is used to update adapter firmware? 

A. adapter policy 

B. host firmware policy 

C. management firmware policy 

D. network control policy 

Answer:

Q4. 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 

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. Which two are true with respect to the switching modes on the Cisco Unified Computing System 62XX Fabric Interconnect? (Choose two.) 

A. End-host mode presents a link to a northbound uplink switch as a host trunk with loop detection that is provided by STP. 

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. 

Answer: DE 

Q7. 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:

Q8. Which item represents a secure method of transmitting fault data with Cisco Call Home? 

A. IPsec 

B. SSL email 

C. secure XML 

D. Cisco Transport Gateway 

E. RSA Digital Certificate 

Answer:

A. 'Shared LOM' NIC mode with 'Active-active' NIC redundancy and DHCP enabled 

B. 'Shared LOM' NIC mode with 'Active-standby' NIC redundancy and DHCP enabled 

C. 'Dedicated' NIC mode with 'Active-standby' NIC redundancy DHCP disabled 

D. 'Dedicated' NIC mode with 'None' NIC redundancy and DHCP enabled 

E. 'Cisco Card' NIC mode with 'Active-active' NIC redundancy and DHCP enabled 

Answer:

Q10. What is true statement concerning port personalities on the Cisco Unified Computing System 62XX Fabric Interconnect? 

A. Fibre Channel uplink ports must operate in Fibre Channel switching mode. 

B. The fabric interconnects use native FCoE storage ports to directly attach to the SAN infrastructure. 

C. By default, all Fibre Channel ports are unconfigured. 

D. The Fibre Channel uplink ports do not support VSAN trunking and Fibre Channel port channels. 

E. The Fibre Channel storage ports support VSAN trunking and Fibre Channel port channels.
