• Question 7:

  How do you examine the attributes of a Dynamic SRDF device?

  A. symdev show
  B. symcfg discover
  C. symrdf list
  D. symdev list
  A. symdev show

• Question 8:

  Refer to the exhibit.

  A database server has its logs stored on a volume on the log source Symmetrix V-Max array and its data stored on a volume on the data source Symmetrix V-Max array. Both source Symmetrix V-Max array frames replicate data to the target

  Symmetrix V-Max array at the Remote site. There are two device groups that have been defined:

  One group for the data volume on the Symmetrix containing the data LUNs One group for the log volume on the Symmetrix containing the log LUNS What happens if the SRDF inks between the Symmetrix contain the data LUNs and the

  target Symmetrix were to fail?

  

  

  

  A. The R2 data in the database remains consistent because Enginuity Consistency Assist (RDF-ECAJ technology would ensure data consistency).
  B. The data in the database becomes inconsistent at the Remote site.
  C. An SRDF failover would be initiated on all volumes and processing will automatically be switched over to the Remote site
  D. The R2 volumes in the Symmetrix V-Max containing the log LUNs would become write-disabled to the database server
  C. An SRDF failover would be initiated on all volumes and processing will automatically be switched over to the Remote site

• Question 9:

  A. 2 hours of data
  B. 1.5 hours of data
  C. 4.5 hours of data
  D. 3 hours of data
  A. 2 hours of data

• Question 10:

  What is the maximum volume size configurable on a V-Max?

  A. 240 GB
  B. 64GB
  C. 256 GB
  D. 480 GB
  A. 240 GB
