A customer is planning to virtualize their current production Oracle environment. To obtain advice, they hired EMC Application Virtualization Assessment for Oracle. After assessing the environment, EMC found that the databases consist of large, single server databases with high utilization, and a small number of application servers with high utilization.
What should be EMC's response to the customer?

• A.This is an excellent virtualization candidate for production databases, but a poor virtualization candidate for application servers, and a good candidate for EMC Unified Storage.
• B.This is a poor virtualization candidate for production databases and application servers, but a good candidate for EMC FAST VP, FAST Cache and EMC Unified Storage, respectively.
• C.This is an excellent virtualization candidate for production databases and application servers.
• D.This is a poor virtualization candidate for production databases, but a good candidate for EMC FAST VP and FAST Cache, and an excellent virtualization candidate for application servers.

Your customer is designing a Proof of Concept with SQL Server attached to a VNX. The storage design includes seven LUNs on a RAID Group. The system is generally very heavily loaded, with a particularly high load on the cache. This is a very carefully controlled environment and your customer has asked for assistance in planning the layout of the LUN location on the physical spindles.
Where in the RAID Group would you recommend placing the two heavily used LUNs if the physical spindle is fully utilized?

• A.Evenly placed, as non-adjacent as possible
• B.Adjacent to each other at the beginning
• C.Adjacent to each other in the middle
• D.One at beginning and one at the end

A customer has implemented a VNX array that hosts multiple SQL database applications, but there are significant performance issues with some of the applications. They have purchased a small number of Flash drives and have asked for your recommendation on maximizing performance using the limited number of new drives.
What suggestion would you make about using the Flash drives?

• A.Remove tempDB and store transaction logs on the drives.
• B.Enable read cache and store tempDB on the drives.
• C.Host transactional logs and tempDB on the drives.
• D.Disable write cache and store tempDB on the drives.

Click the calculator icon in the upper left-hand corner. A customer is building out a VDI environment of 1000 light users and 50 heavy users. They plan to use Boot from SAN for all VDI users. They are preparing a complete HA environment. If boot requires 6300 I/Os, with 5700 write I/Os and 20 seconds to complete. How many I/Os will occur during an HA failover in this environment?

• A.52,500
• B.10,500
• C.105,000
• D.315,000

A customer's database resides on a RAID 5 Pool with SAS drives. Which best practice should be followed to optimize Reserved LUN Pool disk performance?

• A.Use only NL-SAS II drives on dedicated RAID Groups
• B.Use only SAS disks on dedicated RAID Groups
• C.Use equal size thin LUNs from the same Pool as the database
• D.Use a mix of both SAS and NL-SAS disks from the same Pool as the database
