B. The write pending limit of the partition will be raised until it reaches 80%
C. Host write activity to that partition will be throttled
D. Cache will be borrowed from the default partition

Question 2

A customer plans to migrate UNIX and Microsoft Windows clusters from another vendor's array to an EMC Symmetrix. You are responsible for the design of the VMAX 20K solution that is to be replicated to a metropolitan bunker site. There is no tolerance for data loss.
Which data is appropriate for the design of this solution?

A. IOSTAT for Linux and AIX hosts DISKPAR data for Windows hosts SAR data for HP-UX and Solaris hosts
B. IOSTAT data for HP-UX and Linux hosts PERFMON data for Windows hosts SAR for AIX and Solaris hosts
C. IOSTAT data for Linux and AIX hosts PERFMON and DISKPAR data for Windows hosts
D. IOSTAT data for Linux, Solaris, and AIX hosts ERFMON data for Windows hosts SAR for HP-UX hosts

Question 3

An SRDF configuration is running in SRDF/A mode. The customer's decision to switch from SRDF/A to SRDF/S is rejected. At which percentage of write cache in use at the SRDF R2 site will this occur?

A. 90%
B. 50%
C. 100%
D. 80%

A. Save devices store the original track from the source device which is copied on first access.
B. RPQ is required to use RAID1 protection on Save devices.
C. Each Save device is recommended to be equal to or less than the largest VDEV.
D. RAID6 is the preferred protection for Save devices.

Question 5

What can happen if an over-subscribed thin pool becomes full?

A. writes to unallocated extents on TDEV's continue within cache and the virtual pool is not automatically expanded to the needed level.
B. writes to unallocated extents on TDEV's stay in a queued state until the storage administrator can assign additional capacity.
C. writes to unallocated extents on TDEV's continue within cache and the virtual pool is automatically expanded to the needed level.
D. writes to unallocated extents on TDEV's fail and an I/O error is returned. If the host is booting from SAN, this may also result in a server hang condition.
