HP HP0-815 Online Questions & Answers

• Question 1:

  A customer is testing storage array replication with two storage systems in their data center. The arrays are connected with fiber optic cables that are a total of 30 meters in length. The replication mode is changed from synchronous to asynchronous. How does this affect replication performance in this case?

  A. Asynchronous mode replication is much faster than synchronous mode.
  B. Asynchronous mode replication is about the same as synchronous mode.
  C. Synchronous mode replication is much faster than asynchronous mode.
  D. Synchronous mode replication is slightly faster than asynchronous mode
  B. Asynchronous mode replication is about the same as synchronous mode.

• Question 2:

  In many cases, the growth pattern for a storage installation is difficult or impossible to predict. To accommodate this unpredictability, the SAN architect should allow for growth within a predefined design that _____.

  B. is a subset of the mesh for a smaller configuration
  C. uses the ring switch topology as the initial installation
  D. uses the initial installation as a subset of a larger pre-designed configuration
  D. uses the initial installation as a subset of a larger pre-designed configuration

• Question 3:

  Why do customers want to extend the SAN?

• Question 7:

  For HP, what is Data Availability Level 4 in a SAN?

  A. An extended fabric license must be added to all switches in the SAN.
  B. A remote switch license must be added to both switches.
  C. Nothing is required, simply connect the ISLs.
  D. An extended fabric license must be added to both switches.
  D. An extended fabric license must be added to both switches.
