Q1. 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:

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. Which feature must be configured for Linux VMs to be able to transition from Cisco VM-FEX standard mode to universal passthrough mode? 

A. RSS 

B. MSI Interrupt Mode 

C. VEMDPA Agent 

D. Execute Disabled Bit 

E. Processor C State 

Answer:

Q4. Which of the following is true concerning the Global Chassis Discovery policy configuration on the Cisco Unified Computing System Manager when using Cisco Unified Computing System 22XX I/O modules with Cisco UCS 62XX Fabric Interconnects? 

A. The link grouping preference should be set to discrete mode when the number of northbound links are not a power of 2. 

B. Set the action policy-count higher than the actual number of uplinks; otherwise, the Cisco Unified Computing System servers will not be discovered. 

C. For Cisco Unified Computing System implementations that mix I/O modules with different numbers of links, it is best to manually reacknowledge the chassis in order to use all available links. 

D. Automatic reacknowledgement due to chassis discovery is never disruptive. 

Answer:
