Which statement best describes weighted round robin queuing?

Classified traffic is allocated a percentage of the total switch bandwidth according to the level of its priority queue. All other traffic is automatically assigned a lower than normal priority level to create a bandwidth reserve for the highest priority queue. Classified traffic is allocated a percentage of the total switch bandwidth according to the level of its priority queue. If there is no competing traffic, allof the switch bandwidth is available to all traffic, regardless of priority. Each queue holds classified traffic according to priority, and is allocated bandwidth in order from highest to lowest queue number. As higher prioritytraffic is serviced, lower priority traffic gets better access to the remaining bandwidth through dynamic resource reallocation. Switch bandwidth is automatically allocated to the highest priority traffic. All other traffic is held in queues and allocated any remaining bandwidth. Ashigh priority traffic is serviced, the queues are dynamically reallocated to support lower priority traffic.

2.

What are the communication limitations of server blades on a Virtual Connect private network?

They can communicate only with specific nodes by special ACLs implemented within the Virtual Connect domain. They use special VLAN tags to communicate only within Virtual Connect domains. They cannot communicate within Virtual Connect and require external communication through a Layer 3 device. They can only communicate within the Virtual Connect domain and access to external networks or switches is prohibited.

3.

What is the console interface an example of?

in-band management out-of-band management graphical user interface autoconfiguration script

4.

What is a hypervisor?

management software between vSphere and individual virtual machines software that provides a network abstraction layer between Virtual Connect and the server blade software that controls multiple virtual switches as a single logical switch software that allows multiple operating systems to run on a host computer concurrently

5.

What must be done before moving a server profile from one server bay to another?

The operating system on both the source and target servers must be at the same patch level. Both the source and destination servers must be powered off. The source and destination bays must be linked to the same range of MAC addresses and WWNs. The enclosure with the target server must be elevated to the role of base enclosure.

6.

Which flexibility does Virtual Connect Ethernet provide concerning data center network connectivity?

determining which server downlink ports connect to which Virtual Connect uplink ports determining which switch uplink port processes VLAN tags determining which trunk link will receive the majority of LACP traffic determining when broadcast traffic will be allowed on VLANs within Virtual Connect

7.

What is a requirement of a Flex-10 10GbE multifunction BL-c adapter for use on BL2x220c server blades?

It must support the Accelerated iSCSI protocol. It must be a Type I mezzanine card. It must be a Type II mezzanine card. It must consume less than 15 watts of power.

8.

WHICH DEVICE IS A CONVERGED NETWORK ADAPTER (CNA)?

HP NC553i Dual Port FlexFabric 10Gb Adapter HP 4X QDR IB CX-2 Dual-port Mezzanine HCA HP NC522m Dual Port Flex 10 10Gb Adapter HP NC522SFP Dual Port 10GbE Server Adaptor

9.

The FC Mode indicator on uplink X2 on a Virtual Connect Flexfabric 10Gb/24-port module is illuminated solid and not flashing. What does this signify?

There is a logon error in the upstream Fibre Channel switch. Uplink X2 is not passing Ethernet traffic. The SFP device in uplink port X2 has an invalid signature. There is a Flex-NIC configuration error on one of the installed server blades.

10.

Which advantage distinguishes HP FlexFabric technology from the technology supporting other CNAs?

It includes capabilities to support Virtual Connect Flex-10 interface virtualization. Fibre Channel capabilities are supported directly from the FlexNIC to the uplink port. The FCoE standard is enchanced with proprietary Virtual Connect extensions. It provides complete backward compatibility between FCoE and FCIP technologies.
