When designing SRDF/A, what is the recommended configuration for the DSE pool?

• A.RAID 1 devices on dedicated disks
• B.RAID 5 devices spread out over few disks
• C.RAID 6 devices on dedicated disks
• D.RAID 1 devices spread out over many disks

You are designing an SRDF/S solution. Network bandwidth can be purchased in increments of single OC3 (155 Mb/s) links. Data compression is not in use. The workload profile is as follows:
Total I/Os per second = 30,000
Read block size = 4 KB
Write block size = 4 KB
Writes = 30%
How many OC3 links should be recommended?

• A.6
• B.8
• C.2
• D.4

Which SRDF/A feature is recommended for improving resiliency from link outages?

• A.Delta Set Extension
• B.Link Limbo Timer
• C.Increased cache size
• D.Write Pacing

A customer wants to implement virtual provisioning on a new VMAX array and is concerned about efficient use of available storage and application performance.
The VMAX environment will have file system, database and document repository hosts. The customer reports the system hosts append data to the file system, the database hosts use auto-extend and the document repository hosts have low performance and growth requirements.
How should you recommend the host storage be provisioned on the VMAX array?

• A.File system storage on traditionally provisioned volumes; database and document repository storage on thin volumes.
• B.File system, database and document repository storage on thin volumes.
• C.File system, database and document repository storage on traditionally provisioned volumes.
• D.File system and database storage on thin volumes; document repository storage on traditionally provisioned volumes.

For which Symmetrix VMAX SRDF mode(s) is the SiRT feature used?

• A.SRDF/A only
• B.SRDF/S only
• C.SRDF/A and SRDF/Adaptive Copy
• D.SRDF/A and SRDF/S
