    A. True
    B. False

  • Question 247:

    When centrally manage asynchronous remote copy homework through HostAgent, proposed to set asynchronous remote replication time length to:

    A. manual
    B. at the beginning of the synchronization time waiting
    C. at the end of the synchronous time waiting
    D. automatic

  • Question 248:

    About storage arrays between synchronous remote copies and asynchronous remote copies,which statement is correct?(Select 2 Answers)

    A. Synchronous remote copies is the data needs to be written to the main LUN and subordinate LUN,when the main LUN and subordinate LUN writting operations are completed, Then this port storage system complete the operation information feedback to the application server.Asynchronous remote copies is the data which is first written to the main LUN, Upon completion of the writting operation,the main port array will complete the operation information feedback to application server,After the data is written to the main LUN,System will record the difference between main LUN and subordinate LUN,Then synchronize according to the type of synchronization which system sets.
    B. Asynchronous remote copies is the data needs to be written to the main LUN and subordinate LUN,when the main LUN and subordinate LUN writting operations are completed, Then this port storage system complete the operation information feedback to the application server.Synchronous remote copies is the data which is first written to the main LUN, Upon completion of the writting operation,the main port array will complete the operation information feedback to application server,After the data is written to the main LUN,System will record the difference between main LUN and subordinate LUN,Then synchronize according to the type of synchronization which system sets.
    C. Synchronous mode can ensure data synchronization from the main LUN and subordinate LUN,Asynchronous mode has little effect on the system performancE.
    D. Asynchronous mode can ensure data synchronization from the main LUN and subordinate LUN,Synchronous mode has little effect on the system performancE.
