• A.A copy of a database in which Oracle data files are always synchronized
• B.A copy of a database in which transaction logs can be applied to the data files
• C.A copy of a database using consistency technology without putting the database in hot backup mode
• D.A copy of a database using consistency technology by putting the database in cold backup mode

Your customer just enabled symacl on a pair of existing VMAX arrays with SRDF/S replication configured between the frames. What needs to be done next to enable the local management host to manage the SRDF relationship?

• A.No additional access is required, as the local management hosts have full admin rights to the local VMAX.
• B.Assign access type RDF to both local management hosts on its corresponding Remote VMAX frames.
• C.Assign access type RDF to both local management hosts on its corresponding Remote VMAX frames.
• D.Assign access type Base, RDF to both local management hosts on its corresponding Remote VMAX frames.

Click on the calculator icon in the upper left corner. Refer to the exhibit.

You are designing the Symmetrix VMAX architecture for a DAS-to-SAN SQL Server migration. Currently all user databases reside on a single locally attached disk enclosure, mounted to "N:\". You have decided on RAID-5 protected 15,000 RPM drives for the new SQL database and RAID-1 for the transaction log.
Last week, you configured Perfmon to record the current IOPS load of the databases during the 8-hour business day, Monday thru Friday as shown in the exhibit. During an average business day, the transaction log processes 87 GB worth of data.
Following EMC best practices, which discount can be taken from the overall write IOPS, when calculating for the database writes?

• A.1544
• B.792
• C.396
• D.386

Refer to the exhibit.

A customer engaged technical support for a performance issue with their application. The exhibit shows IOPS for the four FA processors utilized to connect the HPUX host to the storage. The FA processors are dedicated to the application. All logical volumes, ports and storage are part of a single masking view. What should the customer change to enhance performance of the host?

• A.Modify host LVM configuration
• B.Correct multipath configuration
• C.Add FA processor capacity
• D.Add FA ports

Refer to the exhibit.

An SRDF/Star configuration has production running at Site A.
A symstar halt command is executed at the workload site (Site A). Which action would reconfigure the RDF device relationships such that the workload site is located at Site B and both RDF targets are in the disconnected state?

• A.A connect action
• B.A reconfigure action
• C.A switch action
• D.An enable action
