HP HP0-Y49 Online Questions & Answers

• Question 61:

  Which technology does the HP Virtual Connect support?

  A. InfiniBand connection to server backplane
  B. Fibre Channel over Ethernet (FCoE) V
  C. Distributed trunking
  D. Intelligent Resilient Framework (IRF)
  B. Fibre Channel over Ethernet (FCoE) V

  ---

  Virtual Connect interconnect modules provide the following capabilities:

  Reduces the number of cables required for an enclosure, compared to using pass-thru modules.

  Reduces the number of edge switches that LAN and SAN administrators must manage.

  Allows pre-provisioning of the network, so server administrators can add, replace, or upgrade servers without requiring immediate involvement from the LAN or SAN administrators.

  Enables a flatter, less hierarchical network, which reduces equipment and administration costs, reduces latency, and improves performance.

  Delivers direct server-to-server connectivity within the BladeSystem enclosure. This is an ideal way to optimize for east/west traffic flow, which is becoming more prevalent at the server edge with the growth of server virtualization, cloud computing, and distributed applications.

  Provides direct-attach SAN and dual-hop Fibre Channel over Ethernet (FCoE) capabilities to extend cost benefits further into the storage network. Reference: http://h20195.www2.hp.com/V2/GetPDF.aspx%2F4AA4-8174ENW.pdf

• Question 62:

  Refer to the exhibit.

  Exhibit HP Comware command output.

  

  Examine this output from the Comware command shown in the exhibit. Based on the flag of ACDEF, what is the status of the aggregated link?

  A. Static LACP link aggregation is configured, and the aggregated link is operational with load sharing not being performed.
  B. Static LACP link aggregation is configured, and the aggregated link is operational with load sharing being performed.
  C. Static link aggregation is configured, and the aggregated link is operational with load sharing being performed.
  D. Static link aggregation is configured, and the aggregated link is operational with load sharing not being performed.
  B. Static LACP link aggregation is configured, and the aggregated link is operational with load sharing being performed.

• Question 63:

  A customer is implementing an access layer solution with four HP Comware switches in an IRF topology.

  The customer expects to add two additional switches of the same model.

  What must the customer do when adding the new switches?

  A. Implement a daisy chain topology to provide better resilience.
  B. Enable spanning tree prevent Layer 2 loops for the newly added switches
  C. Create a second IRF domain for the two new switches.
  D. Verify that the switch model supports at least six switches in an IRF topology.
  B. Enable spanning tree prevent Layer 2 loops for the newly added switches

• Question 64:

  Refer to the exhibit.

  Exhibit Comware switch output.

  

  A network administrator has implemented link aggregation on an HP Comware switch using LACP.

  Assume the two ports are functioning at the data link layer between the Comware switch neighboring switch. The network administrator execution display link-aggregation verbose command and notices the flag of AG for the two links. As

  shown in the exhibit.

  What does this indicate?

  A. The link is marked as a backup because there are already eight active links in the aggregation
  B. The link is up, but LACP failed the negotiation on the port
  C. The link is down
  D. The link is up, but LACP has been disabled on the port.
  B. The link is up, but LACP failed the negotiation on the port

  Port Status: S -- Selected, U -- Unselected

  Flags: A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation,

  D -- Synchronization, E -- Collecting, F -- Distributing,

  G -- Defaulted, H -- Expired

  The flag is a one-octet LACP state flags field. From the least to the most significant bit, they are represented by A through H as follows:

  A indicates whether LACP is enabled. 1 for enabled and 0 for disabled. B indicates the timeout control value. 1 for short timeout, and 0 for long timeout. C indicates whether the link is considered as aggregatable by the sending system. 1 for

  true, and 0 for false.

  D indicates whether the link is considered as synchronized by the sending system. 1 for true, and 0 for false.

  E indicates whether the sending system considers that collection of incoming frames is enabled on the link.

  1 for true and 0 for false.

  F indicates whether the sending system considers that distribution of outgoing frames is enabled on the link.

  1 for true and 0 for false.

  G indicates whether the receive state machine of the sending system is using default operational partner information.

  1 for true and 0 for false.

  H indicates whether the receive state machine of the sending system is in the expired state.

  1 for true and 0 for false.
