C. At login, the user can select the authentication domain to be used. 

D. Cisco Unified Computing System supports LDAP or RADIUS for remote authentication. 

E. A locally authenticated user account is authenticated directly through the fabric interconnect. 

Answer:

Q35. 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:


Q36. Which of the following is true with respect to recovery from failure with automatic pinning that is configured on a cluster of Cisco Unified Computing System 62XX Fabric Interconnects? 

A. By default, server MAC addresses are pinned to uplink interfaces using PIN groups. 

B. When a northbound fabric interconnect link goes down, the affected servers will use NIC teaming to re-establish connectivity on the second fabric interconnect. 

C. When a northbound fabric interconnect link goes down, the fabric interconnect will send a gratuitous ARP to the northbound switch to announce the servers on the new port. 

D. In the event that all uplink ports on the fabric interconnect lose connectivity, the 22XX I/O module shuts down all of the host ports until at least one uplink is restored. 

Answer:


Q37. Which policy is used to update adapter firmware? 

A. adapter policy 

B. host firmware policy 

C. management firmware policy 

D. network control policy 

Answer:


Q38. What are the default settings of the Cisco IMCCIMC NIC properties on a standalone Cisco UCS C-Series server? 

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:


Q39. 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:


Q40. Your systems engineer has determined all of the firmware versions that the server operating system supports. What steps are taken on Cisco UCS to avoid manual firmware upgrades on the blade servers? 

A. Use Cisco UCS Manager firmware management to upgrade all Cisco UCS blade servers to the same target firmware versions. 

B. Configure host firmware package and management firmware package policies and associate the firmware policies with the service profiles. 

C. Create a BIOS policy and define the host firmware package and management firmware package. 

D. Configure host firmware package and management firmware package policies and associate the firmware policies with the server pools.
